What is a gas boiler error?

All models and brands of boilers have their advantages, however, they do not guarantee trouble-free operation. All possible boiler failures have been tested by the equipment manufacturer, they are programmed into the diagnostic system, and based on the results, information on the codes is displayed on the operating panel. Knowing the cause of the failure, you can take comprehensive measures to repair the main or auxiliary boiler equipment.

While there is no generally accepted codification of boiler equipment errors, anarchy reigns in this matter - each manufacturer establishes its own encryption procedure. However, it is generally accepted to encode Latin letters starting with “E” or “F” and numbers from 0 to 100.

The interpretation of the codes is indicated in the technical documentation for the boiler, usually presented in tabular form indicating the error, reasons for the failure and recovery measures.

Design and control of these units

Among the design features of Hydrosta boilers, the following should be highlighted:

1. Availability of a built-in microprocessor. It helps track tuning metrics and smoothly changes the power of the device. The microprocessor also controls the set temperature of the coolant.
2. Forced ventilation system. It effectively removes smoke gases.
3. Remote Control. This is a portable mechanism: the digital indicator and sound signal present on it make it possible to control from a sufficient distance.
4. The functioning of the boiler's key mechanisms is monitored by a telemetry system. If any breakdown occurs, a warning signal is immediately sent to the remote control.
5. Modulated gas supply system. To increase the efficiency of these devices, they were equipped with electronic timers.
6. Hydrosta boilers are small in size, modern in design and easy to operate.

Basic error codes

Error e0 – malfunction of the room temperature sensor. Gas does not ignite properly. It is necessary to check the presence of gas in the system and whether the gas valve is closed. In addition, make sure there is gas in the cylinder or line.

Error e1 – lack of water in the heating system. Insufficient water in the system. You should make sure that the cold water supply system is not broken, check the filters and, if necessary, clean or replace them.

Error e3 - the water in the boiler boiled due to overheating. The water in the heating system circulates unevenly. You need to check whether the filter is clogged and whether the shut-off valves are open enough.

Error e4 - the chimney is clogged. Combustion products are not discharged outside. You need to check the pipes of the smoke exhaust system and, if necessary, clean the pipe or call a specialist.

Error e5 - the burner flame does not correspond to the norm. The automation does not “see” the flame or it does not flare up enough. It is necessary to check the flame control sensor and adjust the burner flame, or call a specialist.

Error e6 - gas leak. Gas is leaving the system. Immediately turn off the boiler and try to identify and eliminate the cause of the leak yourself, or invite a specialist.

Error e7 - the connection between the thermostat and the control panel is broken. Poor contact or broken cables connecting the thermostat to the control panel. Check the cable connections between the remote control and the thermostat and troubleshoot any problems.

Error e8 - the water temperature sensor is faulty. The sensor for controlling the water heating temperature gives distorted information. Check the problematic element and replace it if necessary.

Her mistake is that the fan is faulty. The fan does not work or becomes dirty. Check the voltage supply to the fan and replace it if it fails. You should also check it for contamination and clean it if necessary.

Error ef - the flow switch does not turn off the water for more than an hour and a half. The automation noticed the lack of activity for a long time and sent a message. Check the switch, clean it and, if necessary, replace it.

Error ea – a signal to replenish water is received more than 5 times a minute. The automation noticed that there was too much activity and sent a message about a possible malfunction. You should check the serviceability of the supply circuit, filters and the presence of the required pressure in the water supply.

Water supply filter

Error U0 (uo) – boiler restart. The boiler tries to restart itself when a fault signal appears, which can be eliminated after a certain time or by the consumer independently.

Probable errors and causes of occurrence

If you are not 100% sure what exactly the problem is and that you can solve it, immediately contact the service center to diagnose and fix the problem.

Error code E0 - Temperature control sensor error

Its appearance means a breakdown of the sensor that controls the temperature in the room. In this case, the correct ignition of the gas is disrupted. To eliminate it you need to: Make sure that gas is supplied to the system. Check if the gas valve is open. Check the presence of gas in the cylinder or line.

Error code E1 - Coolant error in the heating system

Its appearance means the absence or small amount of water in the heating system. To resolve this, make sure that the cold water supply system is working properly. Next, check the filters and, if necessary, clean or replace them.

Error code E3 - Water overheating

Boiling water in the Hydrosta boiler. The main reason for this error is uneven water circulation. Check the filter for contamination. Make sure shut-off valves are not closed manually.

Error code E4 - Lack of draft in the chimney

Combustion products remain in the unit and are not discharged to the street. To eliminate this, first check the pipes of the smoke exhaust system. If there is a problem with them, call a specialist or clean the pipe from contamination yourself.

Error code E6 - Gas leak

Its appearance means that a gas leak has been detected in your system. If this error appears, you should immediately turn off the device and, if possible, turn off the gas supply. Next you need to call a specialist.

Error code E7 - Communication error between thermostat and control panel

Its appearance means that the connection between the thermostat and the control panel is broken. The reason for the appearance is a violation or loss of contact. Check and fix.

Error code E8 - Temperature sensor error

It means that the temperature sensor is broken. A broken sensor responsible for the water heating temperature either gives incorrect information or does not provide information at all. Repair or replace it.

Error code EE - Fan failure

Indicates a fan failure. With this error, the fan either does not work at all or works intermittently due to severe contamination. To resolve this, first check whether the fan is connected to the network and whether voltage is supplied to it. Check if it is clean and clean if necessary. If this does not help, a replacement will most likely be required.

EF Error Code - Stream Switch Error

Its appearance means problems with the flow switch, namely, it does not turn off the water for an hour and a half or more. And this problem is reported by the boiler automation, which detected a lack of activity. Make sure the switch is in good working order and may need cleaning or replacement.

Error code EA - Error in the frequency of the coolant replenishment request

This signal is sent automatically, which saw that the request for water replenishment is submitted more often than five times per minute. Check the incident circuit for faults. Inspect the filter. Check the water pressure in the water supply.

Error code U0 - System startup error

With this error, the device tries to start itself several times. It can be eliminated on its own after some time, or the user can eliminate it independently.

It is important to remember that the use of Khudrosta boilers requires the use of voltage stabilizers, since the automation is very sensitive to voltage drops in the network, which happen very often in our country

Mounted boilers

Technical characteristics of mounted units:

1. The heat carrier is completely protected from freezing.
2. The wall-mounted version has a multi-level security system.
3. Sealed firebox design.
4. Hot water circuit. Equipped with two separate heat exchangers. They improve the performance of the device.

Important to know: the excellent production settings of the wall-mounted device allow it to be installed in a very short time.
There is no need to adjust the burner or perform other difficult tasks.

Characteristics of floor-mounted devices

Let's look at the example of Hydrosta HSB. They look like this: These mechanisms have the same characteristics as the wall-mounted options, but they are characterized by higher performance and additional functionality :

1. The heat exchanger is made of stainless steel, which significantly increases the service life (up to twenty years).
2. Reducing noise level. The functioning of the mechanism was based on the forced injection of air and the removal of waste after combustion. A special unit of the device - a muffler - reduces the intensity of noise.
3. The Hydrosta HSB double-circuit mechanism is installed in places with a large volume of heating area. Equipping with a built-in storage container significantly reduces the time for warming up the liquid.

Diesel use

An excellent alternative to gas-powered options is the floor-mounted dual-circuit diesel mechanism: Speaking about these models, we should immediately note their disadvantages:

1. Increased noise during operation of the inflatable burner.
2. The need to install a large fuel tank.

There are also some features of setting up this heating unit. They depend on the type and quality of liquid fuel.

The basic kit of the device includes an expansion tank, a circulation pump and safety options are also included. These mechanisms can be controlled using a remote control or even a smartphone.

Important to know: a double-circuit diesel boiler requires regular maintenance. It includes cleaning the firebox, cleaning the smoke exhaust system, cleaning condensate and more.

If this is neglected, the performance of the device will decrease noticeably.

Why Hydrosta boilers malfunction and recommendations for eliminating them

I can’t figure out how to reduce the pressure of a Hydrosta gas boiler? And is it possible to reduce the gas pressure? Does the device have a regulator that equalizes the gas fuel pressure or does it not need to carry out any regulation? The regulator must adjust the pressure of the fuel supplied to the device. If it is sufficiently low, the burner unit does not ignite; if it is high, then the fire appears to separate from the wick, and the burner goes out immediately after ignition. Here are the adjustment operations. Warm up the boiler sufficiently. Open the smoke exhaust channel fully. Set the main gas burner to the maximum level, at which point the flame will be yellow-blue. By turning off the supply valve, we eliminate the yellow fire. Then check the operation of the unit in all modes. The unit began to hum and heat up immensely, and in addition, the water discharge valve was leaking. Why did this happen? If you are sure that the boiler unit was installed correctly, then first you will need to look at the expansion tank. A situation may arise in which it is preferable to remove it to another place. Along with this, adjustments are made to the unit itself. For example, they examine the water flow or adjust the gas valve, because its incorrect adjustment can cause this deterioration in performance. I have a wall-mounted Hydrosta HSG 100SD boiler in my room. After a year and a half of normal operation, the pressure begins to decrease. We drained the coolant from the expansion tank, then pumped it up and topped it up with water. Everything was carried out in accordance with the instructions, but after some time the pressure drops again. No leaks were found anywhere. We intended to replace the nipple, but we can’t. What is the reason that the device did not maintain the required pressure? How to maintain and adjust the expansion tank? There is no need to drain water from the heating line. We stop the boiler unit. After this, the nipple located at the top of the tank is removed. If water flows, then the expansion tank needs to be replaced. If a small amount of air begins to escape, turn off the filler valve and open the drain valve, through which the coolant begins to be removed from the device. When the water stops draining, connect a pump with a pressure gauge to the nipple and pump up the pressure indicated in the passport. We perform the operation two or three times, since during the pumping period a little liquid is repeatedly drained, so the pressure drops. It is necessary to pump up until the pressure decreases and the liquid flows out. Then screw on the cap, open the taps and add water to the system. We turn on the device and use the air vent to release excess air from the system. Why does the unit start to click when heated? For example, when the burner ignites and the temperature begins to increase, an unusual metallic sound is produced. However, if you remove the screws securing the front panel, then there is no knocking. What is the problem? It happens that the unit begins to make a humming and crackling noise, mainly when the main burner is turned off. This occurs due to uneven heating of the heat exchanger surfaces due to contamination or calcium deposits. You should remove scale and dirt from the boiler as soon as possible. Khudrost boiler, unable to start. The burner lights up if you hold the on/off button. But the unit starts to go out as soon as the button is pressed. Explain to me the reason for the breakdown? The problem is probably a damaged thermocouple or a broken gas valve. As an option, a supply pipeline. has a minimum gas pressure or the control board voltage is very weak. The flame smokes thoroughly and the burner device always burns without dying out. The temperature does not rise above the set level while the fire continues to burn. There is a lot of soot in the boiler. The gas service says that the draft is bad. How can I fix the problem? Apparently there is not enough air. Maintenance needs to be done. Dismantle the burner device, clean and wash the burner and jets. The heat exchanger must be cleaned from the outside. Two days ago we noticed a problem with turning on. For some reason the main burner does not light up, but there is a fire on the pilot burner. Can anyone explain what's wrong? The ignition unit may be damaged. You will need to maintain the boiler and clean the ignition device. There is a gas boiler Hydrosta HSG 200SD. Two days ago he had a problem. The unit begins to go out if a wind flow hits the ignition burner. I changed the thermocouple twice, but nothing changed. How to fix? When the main burner turns on, this serves to reduce the fuel input to the pilot burner, so the automatic safety unit is activated. You need to increase the fuel supply to the ignition mechanism. This occurs periodically due to low pressure in the system. Another reason is a decrease in draft in the chimney if it is designed incorrectly. For what reasons does the device not start and error code E1 is displayed? The pressure is maintained normally and no leaks are visible. I turn off the power, but the alarm is not cleared. Tell me, what is the reason? This situation may occur when the water pressure in the heating circuit decreases. In this case, we recommend checking the pressure sensor. Most likely it is damaged. What is the problem if the boiler stops turning off while the heating reaches the required temperature? Heating goes up to 89 degrees, then goes into failure. After performing a reboot, everything resumes. It looks like the board is damaged, the temperature sensor needs to be replaced, and the protection sensor button is broken. It cannot be ruled out that an automation error occurred. In October of that year, I launched the Hydrosta wall-mounted boiler. About six months later, a failure occurred. I'm trying to set the temperature cycle, but it doesn't register it. Please tell me what is the reason? We assume that the automation fails, and when the temperature rises by 63 degrees, the injectors turn off. It is necessary to adjust the automation for proper operation. Another factor may be that the wrong power of the device is selected in proportion to the heating area. What is the problem when the Hydrosta HSG 200SD boiler does not turn on? In this case, it often shows error E3. What should be done? This malfunction often occurs due to any problems in the thermostat, temperature sensor, as well as malfunctions of the main circulation circuit. Most likely, there is overheating of the water in the heat exchanger. If the thermostat and temperature sensor are not damaged, then the problem is with the control board. It needs to be replaced. Can anyone please help me troubleshoot the chimney duct? Soon it will be three days before a reverse draft occurs, in which the smoke goes straight into the kitchen. I made the chimney myself. It is made of steel pipe. There may be some inaccuracy. The main reason is the incorrect configuration of the chimney. There may be contamination of the pipe with combustion products, which sharply limits its effectiveness. In addition, it is necessary to inspect the ventilation openings in the house. Explain to me how to diagnose the operation of a 3-way valve? There is a suspicion that this component is not fully performing the opening. During the heating cycle, it does not pump distant batteries, but the heating supply pipe under the boiler is heated by the DHW. Of course, you need to inspect the 3-way valve for sticking of the stem in the intermediate state. We also recommend checking the heating system itself. The Khudrosta wall-mounted gas boiler operates for about 2-3 minutes, then the burner turns off and error E4 appears. It glows for no more than a minute, the burner starts working again, and the unit works well for another five to six minutes, and so on continuously. This code, judging by the instructions, means that the draft sensor is triggered, although the chimney is clean and exhaust gases are discharged normally. I just can’t figure out what the problem is? In a particular case, the main reasons contributing to the lack of traction may be: breakdown of the pneumatic traction sensor-relay. The contact between the traction sensor-relay and the electronic board has been broken. The presence of condensate, as well as improper fastening of the tubes with the air relay sensor. The fan is damaged. It doesn't seem to develop the required RPM. When starting up, the unit could have hummed before, but now it makes a louder noise. At first the sound occurred briefly, but now it lasts much longer. occurred briefly, did you encounter this problem? The occurrence of an additional unpleasant sound indicates the presence of scale inside the heat exchanger, which heats unevenly due to different wall thicknesses. The more dirty the heat exchanger is, the louder the noise, and the lower the heat output. I have this device installed. Now, when starting, the wick burns for seven seconds, but the main burner does not catch the flame, which is why the device goes out. How is it possible to get out of the situation? Probably the automatic ignition is not working or there is a problem with the burner. In any case, check whether the phasing is correct when connected to the mains. Hydrosta HSG 100SD boiler in operation. This week the ignition error code E5 is starting to appear almost every day. After resetting using the reset button, the device periodically starts without problems, but this happens sporadically. Just recently I removed the air intake plug and it is functioning better. What kind of breakdown is this? When a chimney error occurs, you must open the safety covers. This will help draw air out of the room. Then inspect the chimney pipe for the presence of ice and, if necessary, remove it. If the failure is associated with flame separation, you need to find out whether gas is entering the room. The Hydrosta wall-mounted gas boiler is in operation. The device quickly raises the temperature to 98 C, and then blocks with overheating. After a while, when it cools down, it starts automatically. What does this depend on? An overheating alarm indicates a lack of coolant circulation. First of all, it is necessary to control the position of the heating radiator taps. They are installed open. Then the cleanliness of the filter element is checked, and you should also make sure that the heat exchanger is not clogged.

Why Hydrosta boilers malfunction and recommendations for eliminating them

The South Korean company Hydrosta is known as the largest manufacturer of plumbing fixtures and components for laying heating and water supply networks. The line of products presented includes ball valves, bimetallic radiators, pipe materials and elements for their fastening.

But gas boilers from this manufacturer are the most popular. The company began producing these products in 2003, and at the moment almost the entire capacity of the enterprise is directed to this industry.

The Hydrosta gas unit is the perfect type of complete micro-boiler. This type of equipment is intended not only for heating homes, but also for heating water.

If you hang two of these boilers, they will solve the problem of heating a house with an area of ​​up to 400 square meters. m. Equipping the unit with a closed combustion chamber allows it to be used in non-residential premises of a house up to five or more floors.

Some recommendations from care professionals

The main warning of professionals is that only specialists should carry out repairs and install such boilers.
Errors during operation will lead to the fact that the mechanism very quickly fails or loses performance. In all other matters, this care does not present any particular difficulties.

You can read how to choose an electric boiler for your home in this article.

You just need to understand the labeling of messages on the display, and then many problems can be fixed on your own. What you need to remember when installing such equipment:

1. The dimensions of the coaxial chimney meet European standards, this simplifies the installation process.
2. The chimney must be equipped with rubber hatches. It should also have special components that prevent the formation of condensation.
3. The boiler is equipped with a flow sensor; when the pressure in the network decreases, the heater stops operation and stops supplying fuel to the burner.
4. To heat a residential building up to 200 sq.m., a large fuel tank (at least 5 m3) must be installed for the boiler. Accordingly, this will require a lot of space.

From the monitoring of consumer reviews, we can conclude that Hydrosta boilers are not inferior in performance to products from German manufacturers. These units appeared not so long ago, and in practice they have not yet been tested whether they will last the 20 years declared by the manufacturer.

You can read how to make an electric boiler with your own hands in this article.

You may also find this article about gas heaters for your summer house useful.

Also, consumer reviews indicate that they often had difficulties purchasing spare parts. But, if there is a service center nearby, then this boiler becomes an excellent alternative to its German counterparts.

Important to know: the excellent production settings of the wall-mounted device allow it to be installed in a very short time. There is no need to adjust the burner or perform other difficult tasks.

• Operating principle. Warming up the exhaust gas is used to produce heat in larger quantities.

Characteristics of floor-mounted devices

Let's look at the example of Hydrosta HSB. They look like this: These mechanisms have the same characteristics as the wall-mounted options, but they are characterized by higher performance and additional functionality :

1. The heat exchanger is made of stainless steel, which significantly increases the service life (up to twenty years).
2. Reducing noise level. The functioning of the mechanism was based on the forced injection of air and the removal of waste after combustion. A special unit of the device - a muffler - reduces the intensity of noise.
3. The Hydrosta HSB double-circuit mechanism is installed in places with a large volume of heating area. Equipping with a built-in storage container significantly reduces the time for warming up the liquid.

Diesel use

An excellent alternative to gas-powered options is the floor-mounted dual-circuit diesel mechanism: Speaking about these models, we should immediately note their disadvantages:

1. Increased noise during operation of the inflatable burner.
2. The need to install a large fuel tank.

There are also some features of setting up this heating unit. They depend on the type and quality of liquid fuel.

The basic kit of the device includes an expansion tank, a circulation pump and safety options are also included. These mechanisms can be controlled using a remote control or even a smartphone.

Important to know: a double-circuit diesel boiler requires regular maintenance. It includes cleaning the firebox, cleaning the smoke exhaust system, cleaning condensate and more.

If this is neglected, the performance of the device will decrease noticeably.

Hidrasec

Suction

After oral administration, racecadotril is rapidly absorbed. The time until plasma enkephalinase inhibition begins is 30 minutes.

Eating does not affect the bioavailability of racecadotril, but after eating, the drug's activity appears with a delay of approximately one and a half hours.

Distribution

In the blood plasma, after the use of racecadotril, labeled with the radioactive isotope 14C, the radiocarbon content was many times higher than in blood cells, and 3 times higher than in whole blood. Thus, the drug slightly binds to blood cells. Radiocarbon is moderately distributed in other tissues of the body, as evidenced by its apparent volume of distribution in plasma of 66.4 kg. 90% of the active metabolite of racecadotril, (thiorphan) ((RS)-N-(1-oxo-2-(mercaptomethyl)-3-phenylpropyl) glycine), is bound to plasma proteins, predominantly albumin. The pharmacokinetic properties of racecadotril do not change as a result of repeated doses, or when administered to elderly patients.

The duration and effectiveness of racecadotril depend on the dose of the drug. In adults, the time to peak inhibition of plasma enkephalinase is approximately 2 hours and corresponds to 75% inhibition at a dose of 100 mg.

The inhibition time of plasma enkephalinase is approximately 8 hours.

Metabolism

The biological half-life of racecadotril, measured as plasma enkephalinase inhibition time, is approximately 3 hours.

Racecadotril is rapidly hydrolyzed to thiorphan, an active metabolite, which in turn is transformed into inactive metabolites. Taking repeated doses of racecadotril does not lead to its accumulation in the body. Data obtained from in vitro

, show that racecadotril/thiorphan and the four major inactive metabolites do not inhibit the CYP enzyme isoforms (3A4, 2D6, 2C9, 1A2 and 2C19) to an extent that may be clinically significant.

Data obtained from in vitro

show that racecadotril/thiorphan and the four major inactive metabolites do not induce CYP enzyme isoforms (ZA, 2A6, 2B6, 2C9/2C19, 1A, 2E1) and conjugated uridine glucuronosyltransferase enzymes (UGTs) to an extent that may be clinically significant.

Racecadotril does not affect the protein binding of active substances such as tolbutamide, warfarin, niflumic acid, digoxin or phenytoin.

In patients with hepatic impairment (Child-Pugh class B), the kinetic profile of the active metabolite racecadotril showed similar Tmax (time to maximum blood concentration) and T1/2 (half-life) and lower Cmax (maximum blood concentration) values. (-65%) and AUC (area under the concentration-time curve) (-29%) compared with these indicators in healthy people.

In patients with severe renal impairment (creatinine clearance 11-39 ml/min), the kinetic profile of the active metabolite racecadotril demonstrated a lower Cmax (-49%) and higher AUC (+16%) and T1/2 compared to healthy volunteers ( creatinine clearance >70 ml/min.).

Cmax is reached 2 hours 30 minutes after application.

No accumulation was observed when the drug was repeated every 8 hours for 7 days.

Removal

Racecadotril is excreted from the body in the form of active and inactive metabolites primarily through the kidneys, and to a much lesser extent in the feces. Excretion through the lungs is negligible.

We troubleshoot problems with Hydrosta gas boilers

The Hydrosta HSG 160SD double-circuit wall-mounted boiler does not start. As long as we press the start button, the burner is functioning. But if you don’t press the button, the device immediately goes out. Explain the reason for the breakdown? The thermocouple may have failed or the gas valve may have broken down. There may also be low gas pressure in the supply pipeline. In some cases, there is a lack of voltage on the electronic board. There is a problem. The start is very difficult. The igniter is lit, but there is no flame on the main burner. Help me figure out what is the reason? Most likely there is a functional malfunction of the ignition device. We recommend servicing the boiler and cleaning the ignition unit. Why does the Gidrosta 100 wall-mounted boiler not turn off when it reaches the required temperature? It heats up to 85C, then crashes. After the restart operation the problem starts again. Perhaps the control board is faulty, the boiler water temperature sensor is damaged, or the protection sensor button is faulty. It cannot be ruled out that there was an error in the automation settings. Please tell me why the boiler does not heat above 70 C? We need to raise the temperature, but the display shows that this is the maximum setting. How to increase the heating temperature? If the unit cannot realize an increase in the temperature of the heating circuit, then the following reasons are likely. In the settings, the maximum heating temperature limit is set to no higher than 70C. There is a decrease in chimney draft. The Hydrosta HSG 200SD boiler is unstable in terms of heating the hot water supply system. Cold and hot water alternately flows from the tap. Tell me why this happens? The sources of the malfunction may be as follows. There is an admixture of cold water due to the fact that the 3-way valve is not working correctly. The heat exchanger is very dirty. We recommend that you clean it. Water leaks regularly from the tap under the boiler. The device itself does not turn on. What should I do? Apparently, there is a discharge of coolant from the safety valve. In this case, this indicates high pressure in the system. The system fill valve may also not be closed or the expansion tank may need to be pumped up. Could you tell me what kind of malfunction occurs when the pressure jumps up around the clock, and at the same time the relief valve comes into action? The heating symbol is always displayed on the screen when the unit is heating up. What should I do? There is a problem with the heating circuit temperature sensor. Water has poor circulation in the heating line. What is the problem if the Khudrosta wall-mounted gas boiler periodically turns off? In particular, recently the ignition did not function at all. The device was cleaned that month. What could it be? It looks like there is a problem with the smoke exhaust system. A chimney inspection is required. Incorrect operation of the ignition element means damage to its parts due to inconsistent voltage or water leakage. Help me fix a problem with my chimney? Soon, three days later, a reverse draft is observed, with smoke immediately penetrating into the kitchen. The chimney was made by me myself. It consists of a metal pipe. There is probably an error in the calculations. The boiler heats the DHW without any problems, but when the heating starts, the water quickly boils and the unit stops working. What could be wrong and how can it be fixed? Perhaps the circulation pump is not working, the electronic board is faulty, or the temperature sensor is faulty. The filter mesh could also be clogged. In the hot water supply cycle, the unit began to alternately produce cold and hot water. I just can’t understand what this depends on. How to adjust the heating of the coolant? Apparently, the heating system is dirty or the heat exchanger needs cleaning. In addition, the pressure control relay may be damaged or the circulation pump may be broken. The main factor is the incorrectly manufactured structure of the chimney pipe. Soot may be deposited on the pipe walls, which greatly reduces its effectiveness. In addition, it is advisable to control the hood in the house. We use a Hydrosta HSG 100SD double-circuit boiler. It instantly reaches 96 C, but then wakes up overheating. Later, when it cools, it begins to start on its own. How to fix the problem? Suspension of operation due to overheating indicates the absence of the circulation process. Initially, you need to monitor the heating radiator taps. They must be in the open position. Next, an inspection is carried out to check for clogging of the filter, and you should also make sure that the heat exchanger is not clogged. I installed this model in the fall of that year. After about 2 months, the device sometimes began to make noise. Explain why it makes noise? Probably the presence of scale in the heat exchanger. If the water is hard, then over time limescale deposits will be deposited on the wall of the pipes in the radiator. Would you like to connect a hydrosta 160 gas double-circuit boiler to the heating system? Tell me how to put such a unit into operation without errors? To correctly put this equipment into operation, you must do the following: Connect the power supply to the unit. Open the gas valve. Then turn on the main burner. Then adjust the desired temperature. I need some repairs done. Please advise how to drain the water from the device yourself? According to the manual, this procedure is implemented as follows. Disconnect the device from electricity. Turn off the gas valve. Open the automatic air vent a little. Open the drain valve completely. Then we clean up the spilled water. If necessary, you can drain the water using the relief valve. This valve is mounted at the bottom of the device. Please tell me how to diagnose a three-way valve? I think that this part does not open all the way. In heating mode, it does not pump distant radiators, but the DHW heats up the pipe for the coolant to flow under the boiler. Of course, we recommend checking the three-way valve for whether its stem is stuck in the middle position. We also recommend that you have your heating system inspected. I installed and connected the HSG 130SD boiler at the dacha. Until this morning I acted without question. At the moment, after five seconds after turning on, it began to go out. It seems that he is unable to deliver water to the system. Tell me, what is the source of the problem? A possible factor for this malfunction may be the ignition electrode, which does not detect fire, or a lack of circulation. Recently a problem was discovered with this unit. While working, he began to whistle. I decided to restart - the attempt was successful, but no changes occurred. Maybe someone can explain what is the reason for the whistling? Very often, a sharp whistle appears if the pressure on the gas burner nozzles is adjusted incorrectly. It is necessary to check the gas pressure adjustments and correct if necessary. The boiler was recently filled with water and began to function intermittently. For example, if you set any temperature, and the heating mode goes from strength to 25 degrees, and then the unit turns off. Tell me what could have gone wrong? If the control board unit has been flooded with water, it is most likely damaged. Try rebooting it by completely disconnecting the device from the power supply. After that, re-enable and check its functionality. We installed a Hydrosta HSG 250SD gas double-circuit wall-mounted boiler a week ago. Today, during startup, the wick burns for 8 seconds, the main burner does not catch the flame, which is why the device goes out. How can I fix the problem? The ignition mechanism has probably failed or there is a problem with the burner. In any case, check whether the phasing is correct when connecting to the electrical network. We launched the same device in the middle of this year. Presumably, after 4 months, a failure occurred in the DHW circuit, although the heating mode is functioning normally. I tried to use hot water, but it only indicates the temperature and does not intend to heat it up. What is the cause of the problem? The problem may be with the 3-way valve. It requires replacement. I would like to know why a safety temperature sensor is needed in a boiler? This component stops the gas supply to the gas burner unit if the water in the main heat exchanger overheats. The main water heat exchanger needs to be washed and cleaned. Tell me what steps to take to remove it efficiently? The primary heat exchanger is easily removed from the unit using a simple screwdriver. Below is the dismantling procedure. Drain the water from the device using the outlet tap. The next step is to empty the hot water system. Unscrew the screws securing the heat exchanger and remove it from the frame. We connected the Khudrost boiler. After approximately three months, the water pressure in the unit decreased. He constantly slows it down and stops. More precisely, it does not hold pressure at all. What could be wrong? If the unit does not increase water pressure, there may be a leak from the make-up tap. If a shutdown occurs and the water pressure decreases to 0, then the three-way valve is defective. Explain how to clean the cold water filter? The first thing is to drain the water from the hot water supply system. Second, unscrew the flow sensor nut. Then we pull out the sensor along with the filter from the recess. After removal, we clean the accumulated impurities and dirt. The HSG 400SD boiler used to hum when it was turned on, but now the noise has intensified. At first the sound was heard for a short time, but now it can be heard for much longer. Has anyone encountered this problem? The appearance of additional noise indicates the presence of limescale inside the heat exchanger, which heats unevenly due to different wall thicknesses. The more dirty the heat exchanger is, the more pronounced the noise is, and the heat transfer decreases accordingly. The appliance is functioning, but water does not appear to be circulating through the system. Very hot. return pump What could have happened? Most likely, the dirt filter is clogged or there are closed taps somewhere, which prevents the passage of coolant. The circulation pump may also fail. What causes hot water to stop heating? The water is barely warm. Tell me, what happened? The search for damage is carried out in the following directions. For example, a breakdown of the DHW temperature sensor requires replacement of the sensor. It is possible that the power settings of the DHW heating device have gone wrong. The spark is constantly broken during ignition. The burner is not dirty, the chimney is normal, the draft is good. What could be wrong? The device does not detect a spark due to a weak signal from the combustion mechanism. Here it is necessary to diagnose the wiring between the ionization sensor and the electrode. It may need to be tightened up. There may also be damage to the sensor insulation, which needs to be replaced.

Hydrosta wall-mounted boiler. After replacing the inlet valve, when the heating was turned on, the temperature began to rise very quickly to 90 degrees. The radiators are connected in parallel, two branches. In this mode, only the batteries closest to the boiler are heated, one on each branch. Everything is fine with the hot water supply. The pump is running. There is no air in the batteries. And how could changing the make-up tap affect it, and everything in the system was closed, both direct and return. There may be several possible faults, but in any of them there is a problem with coolant circulation. Very simply, the coolant was drained from the unit, which means that instead of it it was filled with air, air was forced into the system. Or, alternatively, it lifted dirt from the system and clogged the filter. Need help with this problem. Warm floors and hot water supply have been running from the Hydrosta gas boiler for the third year now. Everything was fine for two years. This spring, during the next visit of the gas equipment maintenance service, it suddenly became clear that something was configured incorrectly. They say that the expansion tank is not configured when starting the unit. And they did something with the expansion tank. They either pumped it up or released the pressure. Don't know. We are used to trusting such serious services. A few weeks later, summer began, the heating system was turned on according to the room temperature, so, naturally, in the summer the device only worked to heat water in the DHW system. In August, my blood pressure suddenly began to drop. Within a day it could drop to a critical 0.5 bar (the light on the display began to blink). Then one day in the village it turned out that there was a break in the water supply line. They turned off the water supply, fixed the leak within 24 hours, and provided water. On the contrary, the pressure began to increase. I had to drain about 200 grams per day so that the pressure did not rise above 1.6 bar. A little later it got colder, and the boiler began to turn on to warm up the TP heating system. The pressure began to increase at breakneck speed. You have to drain up to 4 liters of water per day - the pressure rises from 1.6 to 2.2 bar. We invited the service department - nothing new. They did something to the expansion tank and left. And the pressure continues to rise. Since the departure of the service department, 17 liters of water have been drained in less than 4 days. There are strong leaks in the boiler. The technicians said it was condensation. We suspect problems with the heat exchanger. And does it stop at these 2.2 or does it continue to grow? But 4 liters is something prohibitive. If you're not exaggerating. Well, since you are draining so much, then the problem is no longer in the expansion tank, although of course it could not have been inflated correctly. If so much is drained, it means so much is coming from somewhere. It can only come from the DHW circuit. It flows from it into the heating circuit. There are two possible points where the OB circuit and the DHW circuit can come into contact. This is the feed tap. Leaks, does not close, seal is damaged, twisted. And this is a secondary plate heat exchanger. The fistula is inside this TO. The pressure in the water supply may have increased after repairs, so household (sanitary) water is seeping into the heating circuit somewhere. Open the combustion chamber and inspect the heat exchanger. The Hydrosta gas wall-mounted boiler began to malfunction after 5 years of operation, but I dealt with it myself. Now, after replacing the fuse again, the piezoelectric element has failed. How can I fix it? The standard service life of these models is 5 years, after which endless repairs become unprofitable, and it is better to replace the unit with a new one. Apparently, the power supply has failed or the control board has burned out. Can anyone advise on the Hydrosta hsg 100sd boiler? The heating is working properly, but there is a problem with the hot water supply. When you open the tap, the burner lights up, water flows, but the temperature is very low (25-30 degrees), set to 48. After 1-1.5 minutes, the burner goes out without reaching the temperature. The value 90 appears in the right window of the remote control, but in heating, and the DHW turns on again. And so it repeats. When the DHW tap is opened weakly, the temperature seems to rise. The heat exchanger has just been replaced. The numbers 90, as I understand it, are the temperature of the coolant inside the unit. You have overheating in the heating circuit of the secondary heat exchanger. Usually this is poor heat removal in the secondary heat exchanger, because it is clogged (overgrown with scale), it is washed or replaced. There may also be a blockage in the primary heat exchanger, in which case there will be overheating even when heating is running. Since your heat exchanger was replaced (it is unclear when and which one), call the experts again. The problem is that the pressure in the Khudrost boiler systematically drops to zero, and I cannot understand why. Will a cold water check valve help correct the pressure? You have two problems, most likely unrelated. A pressure drop in the heating system is the result of a coolant leak or release through a safety valve when the expansion tank is “blown out”. And turning on the device when turning off the cold water tap on the mixer is the result of “inflating” the hot water supply tract. When the cold water intake stops, its pressure increases, and if there is room for some more cold water in the DHW tract, it flows in, creating a short-term movement on the flow sensor. This is enough for the boiler to detect that the extraction of hot water is starting and try to start. A non-return valve will help with the second problem - the pressure in the hot water supply tract will not decrease when cold water is taken out, and accordingly, there will be nowhere for it to flow when the pressure rises from stopping the extraction. I noticed a peculiarity that when starting the Khudrosta boiler in heating mode, the burner actually turns on for 30 seconds, heats the water, and then there is a knocking noise (maybe it really boils). It starts working after I drain the water from it, then add new water. Maybe the air vent has become unusable, although it releases air upon startup after filling. If you fill it incorrectly with water, then air may remain in it, and then knocking may occur due to local boiling of water in the heat exchanger. And he may refuse to work. The air vent is designed to gradually (as the coolant passes past it) remove small volumes of air. It produces very little. It is not intended for complete air removal when filling the unit with coolant or immediately after filling. You can try (even if filling not according to the instructions) to disperse the air through the heating system by driving the pump without igniting the burner (preventing the attempt to ignite using the remote control). Then it will slowly come out through the air vent in the unit and on the radiators. In my opinion, it is better to fill the system, including the apparatus, as per the instructions, so that there are no large accumulations of air there. Boiler hsg 200sd, in operation for 3 years. All summer in a disconnected state, a small leak appeared in the lower left corner of the mesh filter housing. Having removed the cap, I discovered that there was a leak at the junction of the tube with the expansion tank and on the other tube behind. I use a mixture of water and glycol - the fluidity is good. The pressure is now 1.2 bar. In both problem areas, the spring clamps are loose and rotate freely. Gaskets along with clamps, or something else? They are only there to prevent it from falling away. Don't think about them. I purchased a hydrosta 350sd boiler, installed it, and started filling it. While filling, water leaked from the case itself, I removed the front cover and found that water was flowing out of this hole. Please tell me what this is and why the water is being discharged? The pressure sensor blinks at zero, i.e. it turns out that there is no pressure in the system, or very little. A gas boiler HSG-130SD was installed, it worked for three years, but a problem arose. When hot water is drawn from the mixer, the pressure in the heating system drops to zero. What could be the problem? Most likely in an expansion tank (expansion tank). When the Hydrosta boiler is operating, something vibrates, it’s not clear that something is rattling inside. I took the cover off, it works, everything is fine. When you close it, it starts to rattle. How to fix it? And when igniting, sometimes the burner starts on the second try. Is this normal or not? If this started in severe frost, then the pipe (outdoor inlets) may have frozen. The unit does not have enough air, and when you remove the cover, air is drawn freely from the room. Hydrosta HSG 160sd. When operating at room temperature, it cannot start normally. When the temperature drops, it starts up, but after a few seconds the temperature on the remote control jumps by a degree and it has to stop. And the temperature immediately drops by a degree again. The boiler, accordingly, starts again. And this happens every time you start. It starts about ten times before the temperature on the remote control stabilizes. Tell me how to solve the problem. What can you tweak? Either the ignition electrode is dirty, or the outside heat exchanger has not been cleaned for a long time, or the gas pressure has not been adjusted, or there are problems with the chimney, both with the air supply channel and the smoke exhaust channel. The Hydrosta wall-mounted gas boiler has been running on liquefied gas in cylinders for 2 years, during which time it has never been serviced. How often should it be serviced? How much does it cost and are parts included in the price? Regular prevention refers to routine maintenance and is recommended as an annual procedure. The burner is cleaned, the automation is adjusted, the cleanliness of the heat exchanger and the serviceability of the circulation pump are checked, and the parameters of all sensors are measured. I have a Hydrosta hsg 200sd boiler, water is dripping from the drainage. How to fix? And another question, how to check the expansion tank if it is removed? The water pressure in the system should be 1-1.2 bar. If the pressure exceeds the norm, you need to reset the water pressure in the heating system to normal. If the pressure is normal, the water discharge valve is most likely faulty (replacement is necessary). To check the expansion tank, you need to remove it from the system, unscrew the black plug, there is a nipple under the plug, you need to take a pump with a pressure gauge and put it on the nipple. The pressure should be 1-1.2 bar. If there is not enough pressure, you need to pump it up. If the expansion tank does not hold pressure, it needs to be replaced. Tell me, what errors may occur during the operation of the Khudrost boiler? If possible, codes and designation. Error E0 - Malfunction of the temperature sensor in the room remote control. Error E1 - There is not enough water in the system. Error E2, E4 - Smoke exhaust malfunction. Error E3 - Overheating. Error E5 - Excessive ignition voltage. Error E6 - Gas leak. Error E7 - Malfunction in information exchange. Error E8 - Malfunction of the temperature sensor in the heating system. Error E9 - Water leakage from the heating system. Error EE - Fan malfunction. Error U1 - Button malfunction. Error Uo - Boiler restart. Error EF - Water flow switch has been turned on for more than 90 minutes. EA error - the water refill signal turns on more than 5 times within one minute. EC error - Incorrect unit model selected. Error Ed - Current frequency deviation. Error U8 - Hot water temperature sensor malfunction. I have a Hydrosta 100 boiler. When hot water is turned on, the boiler starts to whistle, but when heating it works normally. What to do? An increase in power leads to an increase in noise level. To reduce noise, several methods are used: increasing the number of boiler fastenings to the wall, using insulation for the chimney, adjustment may be necessary. Hydrosta 350sd boiler installed. The pump turns on frequently and a hissing sound is heard when igniting. The pump must run constantly. Possible cause of hissing: heat exchanger leakage or boiler boiling. Model hsg 100sd. When idle, the pressure is 1.8 bar, and during operation (heating or hot water supply) the pressure drops to 1.3 bar. Is this normal? It's quite normal. A drop of up to 0.5 at startup is allowed. Hydrosta boiler in operation. When hot water is turned on, the radiators begin to heat up, although the heating of the radiators is turned off. Why is this happening? The three-way valve may be faulty. We recommend calling a service specialist. I purchased a second Hydrosta HSD-160SD boiler for heating a bathhouse. When connected, after 40 minutes, when all modes were checked, the device locked. Error E5, abnormal burner flame, flame breakage. I think it's the gas pressure. The diameter of the hole for the gas-carrying pipe is 10 mm. The appearance of the flame seems to be normal. After calling the service, I realized that you can twist the variable resistors on the board. True, it wasn’t me who spoke personally. It is clear that the “low gas pressure” needs to be corrected. True, there is also a tricky button - “gas pressure device”. It’s clear that you can twist it to the side less and then press the button, but how long should you hold it? You have to look at the moment of ignition. It is possible that only part of the burner lights up, which gives error e5. We need to do normal commissioning. Well, the wrong chimney can give the same error. And a dirty fan. The wall-mounted boiler Hydrosta HSG-200SD is in operation. Over the weekend I redid the chimney system. Previously, the exhaust of combustion products was in the chimney channel for the gas water heater; I converted it through the wall to the balcony by gating the wall, laying corrugation and insulating it. In some places we had to re-weld the propylene heating pipes, as they were in the path of the installed chimney corrugation. I cut them, digested them and then bleed the air just above the welding area. The unit worked for two days with the new chimney. Last night something unpleasant happened: hot water was dripping from it and a puddle formed under it. I opened the front cover to see where the leak was coming from. The entire bottom was in water. At first it seemed that it was oozing from under the hose connection, but then, after looking closely, I realized that it was oozing from under the red valve of the air duct. I don’t understand much about Khudrost’s cauldrons. During the entire period of use, I only pumped air into the expansion tank (sometime this spring) and then this happens. My first thought is that I did something wrong with the new chimney, I removed the chimney pipe, shined a flashlight inside - it doesn’t seem to be jammed anywhere (it could have been jammed during installation), and it doesn’t display the “chimney clogged” error. It works and oozes. The only thing I was able to do yesterday was remove the filter mesh from the unit; the filter was, in general, not clogged with anything, but just in case, I rinsed it and cleaned it with soap. Then he put it in place. I opened the taps, filled the system with water and then looked at what was running from under the red valve of the air duct (on the valve there is a key for a flat-head screwdriver, what kind of valve it is - I don’t know at all, yesterday I saw it for the first time, today I found that it was some kind of air duct) . After a couple of minutes, the leak disappeared on its own, I don’t remember what I did, but the unit worked all night today and there was no leak. Why could there be a leak? I did not bleed all the air from the heating system after welding the pipes, and accidentally “overcooked” the passage hole in the pipe. The pressure in the expansion tank has dropped again, or maybe the chimney has some indirect effect? The idea is to remove, disassemble, and wash the air vent. Remove the air vent, wash it and put it back in place. If it doesn’t help, then buy one with a 1/2″ external thread at a plumbing store and install it as a replacement. A Hydrosta gas boiler was installed, it has been running for 3 years, there have been no problems, but recently we began to notice the smell of gas. We replaced the gas hose with a metal one, but there is still a smell at the connection with the device. We washed it and there was a bubble on the bolt, which is screwed into the gas valve (gas inlet to the device). The question is - what kind of bolt is this, what functions does it have, it just comes out. How can I eliminate gas escaping through it? Screwing it in all the way doesn’t help? It's not very clear which bolt we're talking about. There are 4 screws that secure the valve, screwed from bottom to top - there can be no leakage from them, but there is a screw - a plug on the gas pressure measuring fitting (down under the boiler, screwed into the boss horizontally from you to the wall) - there can be. It can be easily fixed by replacing the seal ring. We have been using the Hydrosta HSG-200SD boiler for the 4th season. And just recently I noticed a slight noise from it. I took off the front panel, listened - the pump is making noise, the noise is in the form of a sort of slight vibration, I don’t even know what to compare it with. What kind of sound could this be? I was also confused by the fact that the pump runs constantly and does not turn off at all, is this normal? Maybe it also always worked before, but I didn’t pay attention to it (there was no extraneous noise). Tomorrow I want to check the pressure in the expansion tank, I think that this has nothing to do with the noise of the pump, but I’ll check it anyway. If it’s based on coolant temperature, then it’s normal, if it’s based on air, then it should stop.
