How to light a junkers power control speaker. Do-it-yourself repair of Junkers speakers, typical faults: goes out, goes out, doesn’t light up. Junkers Version "B"

Typical malfunctions of the Junkers geyser

The Junkers heater is more often subject to problems related to ignition systems. Users complain that over time the wick or burner goes out, the device does not light, and the water does not heat well.

To determine the cause of the breakdown, you need to inspect the parts and check their functionality. We will give examples of common Junkers problems and how to fix them.

The equipment does not turn on, does not light up

Why is this happening? The reasons may be hidden in external factors:

• Incorrect water connection
  . Check the condition of pipes and connections. Open the instructions - make sure that the connections are made correctly and that water flows normally into the system. Otherwise, the pressure in the line will be weak and will not allow the gas valve to open.
• No traction
  . The latest models are equipped with protective sensors. The principle of operation of the draft sensor is to detect its presence. If there is no traction, the sensor sends a signal to the module - the column turns off. The main reason is a clogged chimney. Combustion products are not discharged normally and the burner goes out. There may be poor ventilation in the room. The chimney needs to be cleaned or a vent valve installed.

To check the draft, hold a burning match to the control window. The flame deviates - there is draft, it burns evenly - no.

• A similar situation occurs when the chimney outlet is blocked
  . Look, maybe some object or a satellite dish on the roof is preventing the release of combustion products.
• Overheating
  . Scale deposits reduce the efficiency of heat transfer, which can cause the column to overheat. Then the sensor is triggered and it turns off. Once a year, it is recommended to clean the heat exchanger from scale, as well as install cleaning filters. , read the previous article.

• Sensitive relay
  . You can observe that the burner ignites, then the pilot goes out. Try lowering the room temperature by opening the windows, or replacing the relay.
• . Equipment with electronic ignition receives a spark from batteries. If the batteries are discharged, you need to install new ones.

• Insufficient water pressure
  . Experts recommend selecting a column in accordance with the parameters of your system. If the device is too powerful and requires high pressure, you will have to install a pump or install a new one.
• Abundance of dust
  . If you have not cleaned the parts from dust, the flame in the burner may be distorted and not warm up the thermocouple. Cleaning is carried out with a brush or vacuum cleaner.

The wick goes out. Internal problems

What to do if the equipment stops working? Understand the causes of the problem.

• The rubber membrane is faulty
  . Why is it needed? When you open the mixer, pressure arises in the line, which acts on the membrane. Bending, she pushes out the rod, and it opens the gas valve. If the membrane is damaged or stretched, the system malfunctions. Replace element. More details about the repair are written in the article “”.

• The filter mesh is clogged
  . It is located at the entrance to the water node. It becomes clogged with small debris, pieces of scale, and rust. Remove and rinse the part under running water, you can use a brush.
• Burner clogged in a gas boiler
  . During the combustion process, soot and soot are deposited on the walls. If they are not removed in time, they clog the burner holes. Clean.
• Microswitch malfunction
  . In normal condition, when igniting, a click is heard - the switch is activated. If you do not hear any sounds, then check and change the element.

• The water fittings do not work
  . It is necessary to clean the parts from rust and lubricate them.
• Wiring fault
  . Inspect the entire wiring harness and replace damaged parts.
• Contacts are broken
  . The contact groups are tightened and cleaned.

Other causes of similar problems:

• The gas supply valve is closed.
• The piezo ignition does not work, or the pressing time is short (you need to hold it for 10-20 seconds).
• Mixing of flows when the cold tap is open more than the hot one. The pressure decreases and the wick goes out.

• The gas sensor has failed. Need a replacement.

What factors cause equipment failure:

• Poor ventilation
  . There is not enough oxygen to keep the flame burning. Check the ventilation for blockages. If you have plastic windows, installing a valve for ventilation will help.

• Mixing flows
  .
• Late equipment maintenance
  .
• When connecting, long hoses are used, which reduces pressure
  .

Malfunction at the Junkers gas water heater - the malfunction igniter goes out

In accordance with the requirements of regulatory and technical documents in force in the Russian Federation, maintenance and repair of gas consuming equipment must be carried out by a specialized organization that has a certificate of admission to this type of work, as well as duly certified personnel. Call the service technician accordingly.

Sergey N wrote: The serviceman may suggest short-circuiting the thermocouple if this is the reason. I would not advise you to agree to this; if you turn it off, the column will work, but this does not guarantee its further safe operation.

A serviceman from an official service will NEVER OFFER this, since he is responsible for his actions according to the law, as evidenced by the contract, work order. But “Uncle Vasya is a jack-of-all-trades” - easily! Or he may not offer it, but silently do it “as it should,” and he is not responsible for the consequences!

When to call a professional

If you notice such problems, it is better to contact the service. But before that you need to make sure that it is broken:

• The draft, overheating and flame sensors are constantly triggered.
• The column is clogged.

Often the pipe responsible for the gas supply becomes clogged. How to clean it:

• Remove the temperature control knob.
• Remove the cover of the device.
• There are clamps on top of the pipe. Unfasten them.
• Remove the pipe, clean it, and wash it under the tap.
• Dry and reinstall the part.
• Test the operation of the equipment. While holding down the power control, press the piezo ignition button. Hold for 10 seconds.

If all else fails, it is better to contact a technician to replace the sensors. Many reasons for the damping of the Junkers heater can be eliminated with your own hands. If you connect the device correctly and keep it clean and in good working order, such problems will not arise.

Gas water heaters are necessary for houses and apartments that do not have a central hot water supply. This technique is safe and reliable, it is easy to use, and it allows you to change the degree of heating, which is a big plus.

Signs of improper operation of the igniter (wick)

Why does the wick go out in a geyser - reasons

Let us remind you that the igniter is designed to ignite the main combustion system when water is supplied. The flame occurs as a result of the combustion of a warm air mixture. The igniter heats the thermocouple by physically reaching the main burner.

If the wick goes out, this process fails. In order to prevent overheating of the technical components of the column and, most importantly, gas accumulation, an emergency shutdown of the gas supply is triggered. As a result, the wick goes out automatically.

It is possible to understand that a gas boiler needs extraordinary maintenance without professional knowledge. The consumer can easily verify this by noticing:

• predominance of yellow and orange glare of the flame. Normally, the color of the fire is blue with an acceptable inclusion of yellowness of approximately 10%;
• excessively noisy operation of the equipment. There will not be absolute silence when the speaker is turned on, but strong crackling or rattling sounds indicate possible problems in some unit.

It must be remembered that in a column equipped with piezo ignition, the pilot light is constantly on. This is necessary for the device to operate instantly when the water is turned on. A non-working wick stops the gas supply to the column.

Peculiarities

The characteristics of Junkers indicate that the device is ideally suited to Russian conditions. It is adapted to the pressure maintained in Russian gas pipelines and is equal to 13 millibars. In addition, the system is able to work with the low water pressure inherent in Russian water supply systems. For Junkers, 0.1 atmospheres is enough to perform the intended functions.

Such a gas burner is capable of heating from 11 to 16 liters of water per minute, which is considered a very high figure. In addition, the flame power automatically changes depending on the strength and size of the water flow. The structures are safe and can serve for a decent time. The devices are able to provide fast water heating and look great, which explains their popularity around the world.

Strict design, a variety of models differing in performance, design and ignition system, affordable price and simple controls are among their main advantages.

Design and principle of operation

A typical column consists of a casing that is connected to the chimney through a pipe, a heat exchanger (the best is copper), a gas burner, an ignition system, sensors and a mechanism responsible for supplying gas. The gas water heater is connected quite simply.

Its operating principle can be examined on a model that has piezo ignition.

• The slider is set to the middle position, after which you need to click on it. At this moment, the valve opens and gas enters the wick, also known as the igniter.
• The piezoelectric element, located at the bottom left of the gas column, supplies a spark that ignites the gas. In this case, the slider button is kept pressed for up to 40 seconds. When it is released, the wick still continues to burn.
• At this time, the thermocouple of the column is heated, which will then keep the electromagnetic gas valve open.

You can set the required water and gas consumption.

The influence of a thermocouple on the operation of a gas water heater

This device signals the presence of flame on the igniter. The operating principle is based on the appearance of an electromotive force when two dissimilar metals are heated. The thermocouple tube is a minus. It is attached to the body of the gas water heater, and the central rod is a plus. If the contacts are broken or oxidized, the signal in millivolts will not be sent to the actuator - the solenoid valve. Accordingly, gas will not flow into the column.

Tips: Pay attention to the gasket that isolates the ground from the center wire. If it is damaged, the thermocouple will not work. You can only check the functionality of the thermocouple with a voltmeter

Heat the thermocouple with a candle flame and measure the voltage at its ends. If the readings on the voltmeter increase, then it is working properly.

You can only check the functionality of the thermocouple with a voltmeter. Heat the thermocouple with a candle flame and measure the voltage at its ends. If the readings on the voltmeter increase, then it is working properly.

Varieties

In general, all Junkers speakers can be divided into three groups, depending on the ignition method.

• Those that belong to the B series do not have an igniter that can burn continuously. Two batteries are responsible for ignition, and the speaker itself turns on automatically. Safety systems control draft and flame, there is a fuse. The water pressure in the water supply affects the temperature.
• The P series operates on the basis of piezo ignition. This means that the igniter does not stop working. Water and power have to be adjusted separately.
• Finally, the G series models work thanks to HydroPower technology. There is no igniter at all, and a hydrodynamic generator is responsible for ignition.

Such a water heater can serve up to three water points.

The models produced are standard and mini. The difference between them is only in size. Prices for Junkers brand products are determined based on dimensions and additional services such as delivery and installation. Reviews are most often positive. Users only mention the need to timely clean equipment and remove blockages.

Preference is most often given to Junkers brand models with piezo ignition.

When the hot water tap opens, gas will flow to the main burner. As a result, it will ignite from the pilot and heat the water.

Installation and connection

It is better to entrust installation and connection to a specialist who has been trained in working with this type of equipment. In addition, he will be able to suggest which original spare parts are worth purchasing, diagnose the equipment and prevent any malfunctions from occurring. However, even a professional must follow the instructions that are sold along with the product itself.

• The column is usually mounted in a warm room near the chimney so that the supply of combustion air is not obstructed. There is no need for additional protection of flammable surfaces. The device is installed in compliance with the required gaps separating it from the wall and furniture. The room temperature should be positive.
• First of all, the casing is removed, then it tilts towards itself and rises up. Having connected the Junkers to the gas network, it is necessary to install shut-off valves as close to the installation as possible. Before connecting to the water supply pipes, they will need to be thoroughly washed, otherwise sand, lime and other contaminants will lead to a delay in water supply. Both pipelines (gas and water) must be ideally combined with the parameters of the column.
• To avoid blockages, it is necessary to install protective filters.
• The column is attached to the wall using brackets. It should not rest on water or gas pipes. If the speaker has an electric ignition, you will need to insert two batteries with a power of 1.5 Volts.
• At the end of the work, the shut-off valve and water valves are closed, and the operation of the draft sensor is checked. The launch occurs according to the instructions.

Why is there no draft in the chimney?

There can be several options for the lack of draft in the chimney:

• Soot deposits have narrowed the passage in the smoke channel;
• bricks collapsed and the cross-section of the smoke channel decreased;
• the spider made a web, and the wind blew leaves;
• the birds made a nest.

If there is no draft in the chimney, the consequences can be very sad. Therefore, all gas instantaneous water heaters are equipped with a draft sensor.

Tips: Before you start inspecting the chimney ducts, remove the draft sensor and check its functionality. First, disconnect the wires from the traction sensor, and then connect them together. If the column lights up without a sensor, it means it is faulty.

Check for traction with a lit match. If the flame is drawn into the channel, then everything is in order with the draft.

Operating rules

It should be remembered that some actions can lead to damage to the gas water heater. Junkers operation will be disrupted if fresh air is not provided. In addition, breakdowns will occur when using too long hoses, which lead to a decrease in pressure and the simultaneous opening of hot and cold taps. Naturally, the lack of periodic prevention will also lead to negative consequences.

It was already indicated above how you can turn on the Junkers column - this is done using a valve and a piezoelectric element that can light the wick. Once you light the burner, it will work throughout the day. Moreover, as soon as the hot water tap opens, the boiler will be connected automatically. You can change the gas pressure and water pressure by switching two control knobs.

If you decide to clean gas equipment, this is done according to a certain algorithm.

• First, the gas and water are turned off, then the casing is removed.
• At the next stage, the water unit and smoke receiver are dismantled.
• Finally, the heat exchanger is removed at the end. The radiator can be washed in warm water with a non-abrasive cleaning solution added. The brush should be long-haired and quite stiff.
• The wick and main burner can be easily cleaned using a special awl. In addition, you will have to remove carbon deposits from each injector. However, it is not recommended to do this yourself. It is better to invite a specialist once a year who will combine an inspection with descaling. The professional will also remove deposits, check the tightness of the fittings and clean the plates on the flue gas side.

If there is a smell of gas, it is prohibited to use electrical switches and telephones in the area where the gas burner is located. It is important to immediately turn off the gas tap, open the windows, ventilate the room and call the specialists who installed the equipment. To prevent dangerous situations, do not store liquids or objects that are prone to ignition near Junkers.

When the room temperature drops below zero degrees, the burner turns off and empties.

If such a procedure was not carried out before the winter months, then when connecting the device the next season, you need to check whether the water is heated.

Possible faults

Of course, the operation of any equipment does not always go smoothly; you should be prepared for anything. Fortunately, a significant part of the possible malfunctions that occur with a Junkers geyser can be easily resolved on your own.

There are actually many reasons why the burner does not light.

• It may turn out that both the inlet and outlet pipes were initially installed incorrectly. In addition, the water supply may be disrupted.
• Possible problems with traction. When the chimney is dirty, combustion products do not escape, but accumulate inside, which slows down the operation of the equipment. Craving also suffers due to the lack of fresh air, for example, when the window is closed.
• It happens that the chimney becomes blocked, and this creates a potentially dangerous situation. We urgently need to turn off Junkers and call specialists.
• If the pilot flame goes out, this indicates that the protective relay requires replacement.
• It may simply turn out that the burner does not light because the battery is discharged, and therefore the automatic ignition system does not function. You will have to disassemble the front panel and charge it yourself or replace the battery.
• Low pressure in the main leads to poor water supply, which again leads to operational problems.
• The wick goes out when the flame is uneven. As a result, the main burner also turns off. To solve this problem, simply clean the device.

Sometimes the Junkers speaker does not light up, and sometimes the device turns itself off.

• The first reason is that the batteries have become unusable.
• The second reason is that it is necessary to change the membrane, which has become deformed or torn. It's good when the repair kit contains a replacement.
• The next possible option is that one of the control sensors does not work or the microswitch is worn out, this can be determined by the absence of a characteristic click.

In addition, the igniter may become clogged from the inside, which can be easily fixed by cleaning. An abundance of rust, dirt in filters due to poor quality water and electrodes leads to similar consequences. Finally, improper installation, a closed valve on a gas pipeline, and problems with wires are also common causes of service interruptions.

Gas water heaters are a very popular type of water heater. Having selected a suitable model and installed it in an apartment or house, all that remains is to learn how to turn on the speaker. Among the mandatory manipulations is the opening of the gas tap that supplies gas to the device, as well as the opening of the water tap through which cold water will flow into the device. In this case, your actions will depend on the type of ignition used in your column model.

Malfunctions requiring mandatory contact with a specialist

There are two main reasons why a geyser goes out:

• one of three emergency sensors is triggered: traction, overheating or combustion;
• the column is clogged, which makes it completely impossible to ignite.

Initial actions in cases where the unit stops working:

1. To exclude the first option, you need to make sure there is no smell of gas, and draft is carried out in the chimney. If this is detected, you need to call a professional to clean the smoke valve.
2. The overheating sensor turns on if the heat exchanger is clogged or the control automation does not work. Its purpose is to protect the copper coil. In this situation, ventilate the room and wait until the unit cools down. Contacting a specialist is mandatory, since only a trained gas technician can properly regulate the column after descaling it.
3. If the third sensor is triggered, the gas supply is automatically shut off. In fact, this sensor is a regular thermocouple. If there is a flame, a current is generated and gas is passed through the solenoid valve. When the fire goes out, the valve shuts off the fuel supply for 10 seconds. In this case, you can hear a characteristic sound reminiscent of snapping fingers.

Algorithm of actions when turning off the thermal mechanism:

• stand for 10-15 minutes (to cool the sensors);
• chimney draft is checked;
• the presence of gas is checked;
• the room is ventilated;
• an attempt is made to start the unit (put the power knob in the position required to turn it on, keep it on for 20 seconds, press the “piezo igniter” button);
• if the actions taken did not lead to the desired result, the functioning of the combustion sensor is checked;
• the non-working state of the combustion sensor can be caused by contamination of the pipe, which operates on the principle of a vacuum cleaner, so it should be thoroughly cleaned;

To clean the device that supplies combustion gas (pipe), the following actions are carried out:

• the handle that regulates the water temperature is removed;
• the required ignition position is set;
• the surface of the gas device is removed;
• use a screwdriver to lift up the pipe clamps located on top;
• These clamps are placed separately;
• by moving the lower clamp, the pipe is removed;
• the tube on which dust is collected is washed under running water and cleaned using cotton swabs and swabs;
• a prerequisite for normal pipe cleaning is the removal of all traces of detergent and water;
• the nozzle also undergoes thorough cleaning;
• the tube is installed back into the device, starting from the top mount, where the springy end is located;
• for the lower fastening, you will need to apply enough force to secure the pipe tightly;
• the clamps are put back in their original place;
• a second attempt is made to ignite the column by simultaneously turning on the piezo ignition and power regulator;
• handles and buttons are held in this position for at least 10 seconds;
• The temperature adjustment knob is inserted into its original place.

In addition, the most common reason for the damping of a geyser is described in this video:

Despite the enormous competitiveness of the water heater market, the Junkers gas water heater remains in a leading position. Great popularity has been achieved through the introduction of innovative solutions and properly designed designs. But due to design features and Western standards, Junkers HSVs are susceptible to leaks and breakdowns when used in Russian conditions.

Reviews about the installations are mostly negative and most indicate that Junkers water heaters break down within a couple of years after the warranty expires.

How to light using ignition type?

Manual ignition

This method is already outdated and is used extremely rarely in modern speakers. Such devices are poorly protected both from changes in water pressure and from fire extinguishing.

It is currently not recommended to install such devices at home.

How to light a column with manual ignition:

• Unscrew the valve on the tap that supplies water to the column.
• Light the wick using a match or lighter.
• Open the valve on the tap supplying gas to the column.
• Sometimes, in order to ignite the burner, you need to wait a little until the air comes out of its channel. To speed up the process, first open and then close the hot water tap several times.

Piezo ignition

This option of igniting the column is more modern and widespread. It is very simple to use, but it has the disadvantage of increased gas consumption. While the column is not working, the wick is still smoldering inside it, so the gas, although in small quantities, is constantly burned.

How to light a column with piezo ignition:

• To start, you need to press a button that acts on the piezoelectric element. This will provide a spark to ignite the pilot wick.
• Open the tap supplying gas to the device.

The following video demonstrates this clearly.

Automatic ignition

This is the most modern and profitable option for igniting geysers. It is also called electric because it is based on the transmission of an electric spark. Its appearance is provided either by batteries or a hydraulic turbine. The combustion will be controlled by different sensors, and as soon as the user turns off the hot water tap, the ignition wick will go out.

How to light a column with electric ignition:

• Make sure that gas and cold water are supplied to the column.
• Open the hot water tap.

Watch a short video review.

The Junkers company existed until 1932. From that moment on, the company was purchased by Bosch Gruppe, which, however, did not affect the name of the water heaters produced by the division of the main office.

Junkers flow-through geysers are available in several modifications, differing in the principle of ignition, as well as the type of combustion chamber. Flow-through boilers operating using a pilot burner are popular among domestic consumers. The average service life of a Junkers column exceeds 15 years.

Specifics

PKO Pipe Coil JSC, which produces Astra gas water heaters, has been around for more than fifty years. Perhaps our grandparents also used his products. True, then this company was called differently.

The Astra column is necessary for working with hot water supply. Only gas is used as fuel.

The design of such a column is very simple and includes several components. The main part – a rectangular body – is fixed to the wall. The front panel contains windows for ignition and combustion control, a power button, and gas supply adjustment knobs. At the bottom there are connecting elements with threads on both sides of the gas supply, cold and hot water, and on top there is a section of the chimney pipe.

All key components are located in the middle of the case and secured to the panel located at the rear. It also includes holes for fastening. The firebox is made of good fire-resistant material that has a long service life. Ease of execution is considered an advantage in the model market and provides the manufacturer with great demand for its own products.

The working principle is as follows: in order for gas to enter the gas block and the ignition wick, you need to turn the ignition burner knob to the left and turn on the device by pressing the button - the burner will methodically turn on. The hot water outlet temperature is set by the position of the control knobs. By turning from the right side to the left, the gas supply increases, thus increasing the water temperature, and from left to right, on the contrary, it decreases.

According to functionality, the components of the column are figuratively divided into water and gas parts. On the market you can choose repair kits and spare parts for any unit separately, as well as the entire unit.

The technical properties of Astra speakers make it very easy to compete with other manufacturers. The main advantage is the power of the device: for certain models it is equal to or even exceeds 20 kW. A large firebox and relatively low gas consumption distinguishes this brand perfectly.

Naturally, each model has its own small details in the characteristics, but general values ​​can be derived. For example, the hot water supply is approximately 10-12 l/min, the outlet water temperature range is 35-60 degrees, the operating pressure range is 0.5-6 bar.

The manufacturer also thought about the safety of its own products. If the burner goes out, the water supply will end.

Each model comes with a passport and instruction manual, which outlines operating rules and non-hazardous work in more detail, and also includes an important diagram of the device.

Now on the market there are a lot of gas-powered speakers with an original color palette. Consumers sometimes make the mistake of giving preference to color over technical specifications. The Astra gas water heater does not strive to distinguish itself due to its appearance, but focuses on its ability to work and has its own range of models.

Model 8910-00.02

has high power - up to 21 kW and an operating capacity of 12 l/min. Dimensions – 700x372x230 mm. The chimney has a diameter of 120 mm. Gas consumption per hour is 2.3 cubic meters. m. Ignition occurs manually.

Open type firebox. It is not difficult to study cravings. The gas pipe for connection has a cross-section of 3?4 inches, the water pipes - 1?2 inches. The weight of the device is 15 kg.

Model 8910-08.02

has slightly low power (up to 18 kW) and productivity (10 l/min). However, fuel consumption is also lower - 2 cubic meters. m/h. The weight of the unit is 14.7 kg. Otherwise, the device is very similar to the previous model. Ignition is also done manually

Model 8910-15

It has one significant difference - this system has electronic ignition of the burner, which is very comfortable. Now there is no need to worry about the availability of matches.

The power of the unit can reach 20 kW, productivity – 10 liters of hot water per minute. Gas consumption is 2 cubic meters. m/h. Speaker weight – 13.9 kg. The diameter of the chimney is 135 mm.

Model 8910-16

It is also equipped with an electronic automatic burner ignition control system. This automatic device is a record holder for power (up to 24 kW). The device heats water at a speed of 12 liters per minute. Gas consumption – 2.3 cubic meters. m/hour. The weight of the device is 14.7 kg.

It should be noted that spare parts for Astra speakers can be easily found at inexpensive prices.

Junkers speaker design

The Junkers brand is considered synonymous with quality and reliability throughout the world. The speakers are distinguished by a well-thought-out internal structure and design. The following types of water heaters are offered to domestic consumers:

• The company began producing semi-automatic speakers back in 1968. During operation, a pilot burner is used. Ignition is carried out using a piezoelectric element. The main burner turns on when the DHW tap is opened.
• Automatic - powered by batteries or a hydrogen generator. The series includes simple Junkers geysers with an open combustion chamber, as well as multifunctional models with modulated power. The performance of the burner varies depending on the water pressure.

Only high-quality materials are used in the internal structure of Junkers gas flow columns. All water heaters undergo mandatory testing and are subject to certification.

More information about the technical characteristics of Junkers speakers can be found in the following table:

The marking of the water heater provides detailed information regarding the operating principle and internal structure. A table with explanations of the symbols will help you understand the abbreviations:

• W - Geyser
• R - Power regulator
• 10 — Max. water consumption (l/min)
• –2 — Version 2
• P - Piezoelectric ignition
• B — Electronic ignition system with batteries (1.5 V)
• G - Electronic ignition system from a hydrogenerator
• 23 — Designation number for working on natural gas N
• 31 — Number of designation of operation on liquefied gas
• S…. - Code of the country

Installation of a Junkers instantaneous boiler

The operating instructions provide a detailed plan for connecting the water heater. In particular, the following is stipulated:

After connecting the instantaneous water heater, a commissioning mark is placed in the passport. From this moment on, the Junkers column is subject to warranty service.

How to light a Junkers gas water heater

The vast majority of Junkers water heaters offered to domestic buyers operate in semi-automatic mode. Ignition of a semi-automatic gas boiler is carried out as follows:

• on the front panel of the water heater there is a valve that opens the gas supply;
• the button is pressed and the wick is lit using a piezoelectric element;
• the gas valve is left clamped for another 20-30 seconds;
• Now the button is released, the flame on the burner should continue to burn.

The pilot burner remains on throughout the day. When you open the hot water tap, the boiler will turn on automatically. Adjustment of the gas water heater is carried out on your own, using two knob regulators: changing the gas and water pressure.

How to determine that there are internal faults in a gas water heater

The reasons why the water heater goes out may be the following:

• filters are clogged;
• the membrane is deformed.

If the quality of water supplied to the room is unsatisfactory (for example, hard, with a large amount of lime impurities), the metal filter grid becomes clogged. To restore the normal functioning of the unit, it is necessary to clean (replace) the mixer filter. Cleaning can be done with conventional detergents to remove rust and scale.

It is also important to clean the column itself from soot formations.

To examine the membrane, the bolts that secure the front panel of the speaker are unscrewed.

When inspecting the membrane, attention is paid to its shape (so that there are no deformations) and the presence of any chips. If such defects are detected, it must be replaced.

And it is better to choose a silicone membrane, since its surface is more durable and elastic

If such defects are detected, it must be replaced. And it is better to choose a silicone membrane, since its surface is more durable and elastic.

In this regard, the service life of this part will be longer.

To install the membrane, it is better to use the services of specialists, which will undoubtedly be safer. In addition, when you call a technician, you can simultaneously carry out a general cleaning of the unit and conduct a full diagnostic of the device.

The reasons for the attenuation of the gas column may also be the following:

• unequal pressures of hot and cold water, which can be solved by simply regulating the water supply;
• lack of cold water before starting the unit, which, by the way, leads to rapid damage to the column;
• insufficient time to hold the ignition button (20 seconds is the required duration);
• There is a malfunction of the flue gas sensor, which can be determined by calling.

How to clean a Junkers column with your own hands

Any repair work on gas consuming equipment must be carried out by a specialist who has the appropriate work permit.
Cleaning the pilot burner and heat exchanger is a job that you must not do yourself. Maintenance is carried out at your own risk. To clean your Junkers speaker at home you will need to do the following:

• turn off the gas and water supply;
• remove the casing;
• disconnect the smoke receiver and water unit;
• pull out the heat exchanger.

The water heater radiator is washed in warm water with the addition of any non-abrasive detergent using a stiff, long-bristled brush.
You can clean the wick and main burner using a special awl. Clean each nozzle, removing carbon deposits. Do-it-yourself repair of Junkers geysers results in the manufacturer’s refusal to provide warranty service for the equipment.

Conclusions and useful video on the topic

You can see more clearly the most common breakdowns of Junkers boilers and their self-repair in the video.

Troubleshooting the flow sensor:

Do-it-yourself Junkers boiler repair:

As a conclusion, we can note that not every error generated by the boiler self-monitoring is fatal. Do not be afraid to repair the Junkers boiler yourself: many faults can be eliminated without the help of a specialist. But we don’t recommend tampering with the gas pipeline and soldering the board yourself, it’s too risky.

Junkers speakers - malfunctions and methods for eliminating them

German water heaters rarely fail.
With regular maintenance, the likelihood of a breakdown is reduced to zero. The main malfunctions of the column are the attenuation of the wick and main burner, failure of the membrane, and the water unit. The described breakdowns are associated with low quality water and gas. Descriptions of breakdowns and methods for troubleshooting Junkers geysers are given in the table:

Geyser JUNKERS WR-13 2B

Despite the fact that the modern market for household heating devices is saturated with a variety of electrical appliances, a gas water heater remains the most popular means of providing a room with hot water. It is this device that deservedly leads among the most functional units, capable of simultaneously supplying hot water to several water points.

Today's industry offers a solid selection of devices, but Junkers geysers, the operating instructions for which will be described below, are a product characterized by ease of use, reliability, durability and economical fuel consumption.

Service center for repair of geysers LLC "TeploSpetsCenter"

Today it is impossible to imagine a city apartment without a gas water heater. - This is the most affordable and reliable equipment for heating cold water. The column simultaneously supplies hot water to several water supply points - to the faucet in the kitchen, to the faucet and shower in the bathroom. A breakdown of the unit entails a lot of everyday inconvenience.

Regardless of their service life, speakers from even the most recognized manufacturers sometimes fail. Insufficient water heating speed, yellow or green flame in the burner, loud hum during operation, black soot flakes are typical consequences of non-periodic or unqualified maintenance of units.

Breakdowns and repair methods for speakers

The main reason for the failure of a gas instantaneous water heater is mechanical or natural wear and tear of the working elements of the device. Mechanical wear includes cracking of the membrane gasket, failure of the solenoid valve, and combustion of the thermocouple. Natural wear and tear of components is clogging of the water purification filter, contamination of the heat exchange unit, clogging of pilot tubes and burner nozzles.

The wick fades after releasing the gas button

This is the most common device failure. The cause of the breakdown is a clogged igniter channel or failure of the bimetallic sensor.

To eliminate the malfunction, you should call a service center technician. The technician will clean the column, thereby extending the service life and warranty of the water heater.

The column does not heat the water quickly enough

It happens that the column does not heat running water quickly enough, and when cold weather sets in, it does not work at all. Check the integrity and flexibility of the membrane gasket. If cracking or loss of flexibility occurs, replace the membrane with a new element. If the structure of the membrane is not damaged, clean the surface of the gasket and put the element in place.

To ensure that the dispenser operates without failures, perform maintenance on the unit once or twice a year. To do this, it is recommended to contact our company. The first maintenance is carried out before the onset of winter cold, and repeated maintenance is carried out in the spring, after the heating season has passed.

The column locks after a few minutes of operation

Check the air draft in the chimney duct. To do this, attach a sheet of paper to the chimney opening. The sheet of paper should be held on the wall by the flow of outgoing air. The second way to check traction is with a burning match. Place a burning match near the chimney opening and observe the flame. If the flame rushes towards the chimney, the draft is normal; if it deviates from the channel, the draft is broken.

To restore air draft, clean the chimney of soot, dust, and small debris. To conduct a complete audit of the gas exhaust system, contact specialized companies. Trained engineers will conduct a comprehensive system check using special equipment.

Repair of geysers at the customer’s address

Regulatory requirements prohibit the dismantling of gas instantaneous water heaters that are connected to the main gas pipeline. According to the rules of the gas supervisory service, the user must call an engineer to his home to carry out service work.

To carry out scheduled maintenance or repair of a gas water heater, a routine or comprehensive audit of the flue gas removal system, please contact our company. We will send trained installation engineers who will check the technical condition of the chimney and unit, identify possible malfunctions in the operation of the equipment and eliminate breakdowns.

Now the time has come to write an article not about computers and 1Ski, but about repairing a Bosch/Junkers WR13 gas water heater. Who would have thought that an IT specialist would climb there. It’s a tradition that such things are best left unchecked in the departments of gas companies and without special knowledge. In fact, there is nothing terrible there, and with more or less straight hands, you can do it yourself. Moreover, there is a crisis in the country and you want to save money. It all started when the heater stopped going off when the hot water was turned off, so I had to run and turn off the gas manually. Googling suggested that two main blocks are responsible for this: hydraulic fittings (water unit) and gas fittings. They are connected together in such a way that when water is supplied, the water unit, using a membrane pressing on the pin, presses on the gas valve, thereby opening the gas supply. When the water is turned off, the gas valve closes. In general, the problem is somewhere here! (number 14 in the picture)

So, let's get started... Here is our patient:

All we need is 2 screwdrivers (Phillips and flathead) and a wrench to unscrew the nut securing the water pipe. For safety, we will cut off the water and gas supply to the apartment. Remove the protective casing by unscrewing the two screws from the bottom:

We gain access to the insides: Remove the bracket securing the water supply pipe to the heat exchanger:

We take out the pipe itself:

Unscrew the two screws securing the water unit to the gas fittings:

And then I saw a picture of oxides at the attachment point. The mechanism was blown apart and water leaked out. The metal oxidized and began to jam the gas valve (it stopped returning to its original position). This is the reason for not turning off the gas supply! Let's try to clean everything up as much as possible and develop the valve itself:

It should press inward and return to its original position. Now let's look at the water block itself:

We take out the bracket and take out the flow regulator (sleeve with a spring):

Unscrew the bolts and remove the water unit cover:

Underneath we see a worn membrane:

And the lid itself has fallen apart over time (the column is currently 7 years old):

As it turned out, spare parts for gas water heaters are not so easy to find. And the prices for them, frankly speaking, are outrageous. With the price of a new Bosch Junkers GWH 13 P (WR13-2 P2) speaker – 10,000 rubles. I found the cheapest membrane in the city (code 8700503083) for 1,400 rubles. and water fitting cover WR10, 11, 13, 15 (code 8705500105) for RUB 2,400. Total 3600 rub. More expensive than a third of the column. So before you start repairing, think about whether it is necessary. But it was already too late... the column was disassembled and I didn’t want to install a new one, so I decided to continue what I started! (although I almost freaked out and didn’t go for a new Chinese one for the same money) The picture shows old and new parts. The difference is immediately visible:

Now we install a new membrane and water valve cover, assembling everything in the reverse order:

Hooray. Everything worked out for me. Now the flame lights up and goes out as it should! What do you want to say in the end?! When I was puzzled by the choice of column 7 years ago, Junkers were praised as the most reliable and repairable. I find it difficult to say whether 7 years is a lot or a little for reliability, although the old Soviet ones still work for people and at least they care! But at such prices for spare parts, this maintainability is not needed. Now I would choose the cheapest Neva or Chinese Oasis for 4-5 thousand rubles and if it breaks, I would simply throw it away without worrying and install a new one for the price of repairing this Junkers/Bosch. One hope is that this prevention will allow the column to work for at least as long... And finally, for those who don’t understand the pictures, I’ll give a link to a video on disassembling Bosch/Junkers gas burners from the company Teplotekhnika St. Petersburg: https://www. youtube.com/watch?v=a2aIn93fyQ8

About the benefits

All Junkers geysers were adapted by the manufacturer to Russian operating conditions:

• Gas pressure - this indicator in Russia is somewhat different from the European one. Therefore, a dispenser that is not adapted to natural gas pressure according to Russian standards can significantly reduce its performance.

Junkers designers have created a special version of water heating devices for the Russian market.

• Water pressure - a common problem is low water pressure, especially in apartments located on the top floors of old buildings. The Junkers geyser is capable of operating at any water pressure.
• High performance - the products of this brand are in no way inferior to such well-known brands as Bosch, Ariston or Mora.
• Modulation - all Junkers speaker models are equipped with a special flame modulation system. That is, the power of the unit will change automatically depending on the amount of water flowing at a particular moment.
• Safety - the products of this brand are equipped with all the necessary elements that guarantee safe operation, namely, control of draft, flame and overheating.
• The service period is 30 years.

Features of column selection

The main difference between different models of geysers is the method of ignition, whether it is a product from junkers, bosch, Neva or Lux. Today it is very rare to find a device that is lit with matches, so this option is not even considered.

The most popular speakers today are units with piezo ignition. In them, you just need to press a button located on the device panel. In addition, such units provide the ability to set the desired temperature of the supplied water.

Dispensers with electric ignition are the most expensive option, which allows you to significantly save gas. The device is turned on automatically by a flow of water. Purchasing such products allows you to save on energy costs and get heated water with maximum convenience, which justifies the high cost of the water heater. Modern geysers, which are offered by well-known brands, as a rule, have three-level protection:

• From the flame dying out.
• Lack of draft in the pipe.
• The occurrence of such a process as reverse thrust.

The equipment is protected from overheating by a hydraulic safety valve.

External signs of a geyser malfunction

If the junkers gas water heater does not light up, the reasons for this may lie in external factors not related to the condition of the main equipment.

• Incorrect piping. In this case, it is necessary to check the connection of both the inlet and outlet pipes, which will also ensure an uninterrupted water supply.
• No traction. This is usually caused by the chimney being clogged with a large amount of dust or foreign objects. Thus, combustion products are not removed and the burner goes out. In such a situation, you need to bring your hand to the chimney or a small flame (from a match or lighter). An important condition is the presence of an open window. If the draft level is sufficient, the flame will be deflected, and air movement will be felt on the palm.
• There is an unpleasant smell of gas in the room, which may be caused by neighbors installing an antenna above the chimney. In this case, you must immediately turn off the water heater, ventilate the room and call special gas services.
• The column ignites, but after a while it fades out. This may be caused by excessive “sensitivity” of the protective relay. In such a situation, it is necessary to cool the room by opening the windows and contact service to replace the relay.
• A discharged battery or battery may also cause the automatic ignition unit to not operate. This indicates the need to replace them, which you can do yourself.
• Low water pressure may indicate a malfunction of the junkers geyser if the water pressures, for example, in the bathroom and in the kitchen, are different. If they are equally small, then the reason is a weak water supply network.
• Extinguishing the wick can be caused by an oblique, uneven flame. As a result, poor heating of the thermocouple occurs, which automatically turns off the unit. In this case, it is necessary to clean out the dust, which is a mandatory preventive measure when the wick goes out.

Brief operating instructions

Column operation

The main thing that the buyer needs to do after a geyser has been installed, be it a Junkers or Ariston product, is to carefully read the operating instructions from the manufacturer.

The lifespan of the unit largely depends on its correct use. That's why:

• Installation, as well as subsequent maintenance of the device, should be trusted only to professionals.
• It is necessary to systematically clean the igniter and heat exchanger.
• Do not set the water temperature too high, as this can lead to rapid scale formation on the walls of the heat exchanger.
• If the water hardness is too high, it is necessary to equip the column with a special device to prevent the formation of scale.

Recommendations for safe use

If you are interested in the manufacturer Junkers, you can purchase a gas water heater from this company in any store of relevant goods at an affordable price. However, you must follow rules that will ensure the safe operation of the equipment. Replacing the device is not a panacea for troubles that arise during the operation of the device - this is what reviews say. Junkers geysers rarely become the cause of dissatisfaction that arises from the quality of the device. If you want to get a speaker that will serve for a long period of time, then you should follow the operating instructions.

Maintenance, as well as installation of the device, should be carried out by professionals; these manipulations should not be trusted to people who do not have sufficient specialized knowledge

It is important to clean the heat exchanger and igniter from time to time, which act as fundamental factors for the correct and stable operation of the unit

If you are interested in the manufacturer Junkers, a geyser from this supplier will certainly please you with its quality characteristics. However, in order not to speed up the end of operation of the device, you should not experiment with very high heating temperatures of the coolant, as this can accelerate the process of deposits that form in the heat exchanger. If the water in the system is sufficiently hard, it is recommended to supplement it with Anti-Scaling, which will extend the life of the column.
