Do-it-yourself oasis geyser repair, diagram, instructions

Malfunctions happen in any equipment, regardless of the manufacturer. Be it a famous German brand or its Chinese equivalent. The difference is that in the second one they occur more often.

The breakdown of such an irreplaceable device as a geyser creates a lot of inconvenience. If the malfunction is not related to a gas leak, in most cases, you can repair the Oasis geyser yourself. We will talk in detail about what kind of breakdowns are most often diagnosed in speakers of this popular brand among users, as well as how to fix them in this publication.

Possible reasons

In case of incorrectly connected pipes, the water heater protection system itself blocks the gas supply, which is why it does not turn on.
The pipe connection diagram is very simple: The gas supply pipe is connected on the left, the cold water supply pipe is connected in the center, and the hot water outlet pipe is on the right.

It is also necessary to ensure that all gas supply valves are in the open position. It may well be that after installing new equipment you simply forgot to turn on one of them. All taps with yellow handles must be open.

No or poor draft in the chimney.

Accumulated soot, construction debris or other foreign objects entering the chimney can prevent combustion products from being removed through the chimney, which poses a danger not only to the health, but also to the lives of residents.

hood

You can easily check the presence of draft in the chimney yourself. To do this, you just need to bring a burning match to the inlet. If its flame rushes towards the hole, then the chimney is working properly. Otherwise, you will have to look for the reason why there is no traction. As you can see, an ordinary match can help eliminate a dangerous malfunction and protect your household from carbon monoxide poisoning.

If there is no draft, make sure that there are no obstacles above the ventilation shaft exit, such as a satellite dish. In this case, the problem can be completely solved without seeking help from specialists.

If no external circumstances interfere with the proper operation of the chimney, then you are definitely dealing with contamination. What to do in this situation? Of course, you can try to clean it yourself, but there is a possibility of damaging the branches from neighboring apartments.

Increased relay sensitivity.

The most likely cause of the malfunction is the increased sensitivity of the thermal relay, the protection of which is activated against overheating, stops the gas supply and the column goes out.

Protection system

It usually includes three main elements:

ionization electrode for flame control, responsible for supplying/cutting off fuel supply when the burner goes out;
a draft sensor that blocks operation if there is no normal draft in the chimney;
hot water heating sensor, which turns off the column if the water temperature reaches the maximum level, which is dangerous due to burnout of the heat exchanger.

These are the main elements of column protection, but there may also be additional ones, for example, a safety valve, through which excess water is removed when the pressure in the system is exceeded, which is necessary to avoid problems; a sensor that prevents the dispenser from turning on if the water pressure in the system is critically low, and others.

Note that many new generation columns can function properly even with low water pressure in the system. For example, geysers work properly even at a pressure of 0.1 or 0.2 bar. Rest assured, even if there is little pressure in the tap, the burner will start working and the water will heat up.

The water heater protection system ensures safe use. Fears of a gas leak that could poison people, or a dispenser exploding when the water is turned off prematurely, are a thing of the past.

Now you know how modern gas water heaters differ from the water heaters that can still be seen in Khrushchev apartments. After familiarizing yourself with the main characteristics, you will have fewer doubts in choosing a speaker. If you still have questions, you can contact our managers by phone 8-800-555-83-28. We work to ensure that your water heater purchase is truly enjoyable and rewarding.

Every person who has decided one day to be independent from the central water heating system knows what a geyser is. Some install such speakers for completely different reasons, but everyone faces the same problem: when connected, the speaker does not always produce the results that are expected. There are situations when work goes wrong due to wear and tear, and subsequently repairs. Every year, speakers with fully automatic settings are becoming increasingly popular, while not every person decides to switch to them for the same reason. Due to the fact that the speakers can be extremely different, they only have the same setup principle, while all other steps may not have any similarities at all.

Setting up a geyser is a short but rather painstaking process, which for the first time can take much longer than expected.

Causes of breakdowns and their elimination

Despite the simplicity of the design and ease of operation, the flow-through heater is not immune to breakdowns. If the Vector brand geyser does not turn on, do not panic. There may be several reasons for the problem and most of them can be eliminated yourself.

Problem #1 - lack of traction in the column

The lack of draft indicates that combustion products cannot be promptly removed from the room. This poses a danger to users, so the sensor turns off the gas water heater.

Sometimes the burner lights up but goes out immediately. This can happen when there is not enough air to burn the gas - the flame goes out due to lack of oxygen to support combustion.

In any case, you first need to check the draft by holding a burning match to a special hole on the speaker body. If the flame is directed inward, then the chimney is working normally, combustion products will be promptly removed, but the cause of the malfunction lies elsewhere. If the flame remains motionless, directed upward or towards the user, then it is worth carefully inspecting the chimney and cleaning it.

Along with combustion products, soot enters the air. It gradually settles on the walls of the chimney, narrowing its opening. As a result, traction disappears. The problem can be solved by thoroughly cleaning the chimney

Problem #2 - difficulties with water pressure

Another reason why a Vector brand household gas water heater does not light up may be low cold water pressure or its complete absence. Before you start looking for a solution to the problem, you need to make sure that cold water is supplied without interruption and evaluate its pressure. If there is insufficient water pressure in the system, the solution may be to install a pump or replace old, clogged pipes.

If there are no problems with the water supply, you should proceed to inspect the column. The solution to the problem can be adjusting the water supply to the column. To do this, you must fully open the corresponding tap.

Another reason for insufficient water pressure in the column is a clogged filter. To inspect it, it is necessary to turn off the water and gas supply to the valves, unscrew the nuts, and rinse the mesh. If you cannot clean it, the filter will have to be replaced.

It will take a few minutes to inspect the filter. However, in some cases, washing alone is not enough; a complete replacement of the part is required.

Problem #3 - insufficient gas pressure

Sometimes the gas pressure is not enough to ignite the flow column and allow it to operate normally. However, you cannot solve such a problem on your own. You need to contact your gas service.

Problem #4 - no ignition when turned on

The presence of an electric ignition system ensures comfortable operation of the gas water heater and eliminates the use of a wick that is constantly burning. However, it is this element that can cause the device to malfunction.

When the tap is opened, automatic ignition should be triggered. This action is accompanied by a characteristic crash. If the ignition does not work or the spark is too weak to ignite the gas, the column will not be able to connect. Replacing the batteries will help solve this problem.

For uninterrupted operation of the instantaneous water heater, batteries are required. When the batteries are discharged, the electric ignition does not work and the speaker does not turn on.

Problem #5 - clogged pipes

Water and gas pass through the Vector gas water heater during operation. Using filters allows you to clean them from unnecessary impurities. However, the presence of blockages may cause the device simply not to turn on.

However, the filter is not always able to bring water to an ideal state. Soluble salts enter the heater along with the liquid and settle on the walls of the heat exchanger. As a result, the patency of thin tubes is impaired.

Specialists remove scale using specialized reagents. A home technician can deal with it using a solution of citric acid or vinegar. To clean the heat exchanger, you need to remove it and place it in a warm solution with vinegar added. You can also use special purchased products - “chemicals” designed for cleaning heat exchangers.

It is better to entrust the removal of heat exchanger blockage to qualified craftsmen, since the tubes are fragile and, in the absence of specialized skills, can be easily damaged

We discussed cleaning and repairing the heat exchanger in detail in the next article.

How to prevent breakdown of the Oasis geyser

In order to prevent a situation where repair of the Oasis geyser is required, it is necessary to properly care for gas equipment and operate it correctly. These are the recommendations that can be read in the instructions for geysers. Here are some operating tips:

You need to monitor the battery charge.
When turning off the unit, you must first turn off the water.
If the unit is turned off for a long time, then it is necessary to shut off the supply of bitter water.
Periodically clean the column from scale.
Use only the gas recommended by the manufacturer.
Do not turn on the column if there is no traction.
Do not carry out repairs yourself.

Features of using batteries

Of all the parts, batteries require the most frequent replacement. For geysers, you should choose only alkaline batteries made using Alkalin power technology, size “D” and the first letter “L” in the designation is LR20. Their capacity and service life are five times greater than those of salt ones: from 1 to 1.5 years.

It is better not to buy elements that are too cheap, as they may turn out to be fake. It is possible to install NiMH or Li-Ion batteries, but their price with a charger is higher

High-quality batteries cost from $1.2. There is a radical way to reduce the cost of replacing batteries - converting the speaker to power from the mains.

To do this, you can buy a special 3 V power supply, or use a 5 V mobile phone charger with an additional stabilizer. The main requirement is that its power is sufficient for ignition, which occurs at a supply voltage of 3 V and a current of 350 mA.

In case of a power outage, you can always keep batteries in reserve; fortunately, alkaline batteries have a shelf life of 5 years or more.

Column heat exchanger quality

When choosing a column, special attention should be paid to the quality of the heat exchanger. The type of metal and its quality have a great influence on the lifespan of the radiator. They are made of galvanized steel, stainless steel, copper.

The most durable of stainless steel, but inferior in thermal conductivity to copper. Accordingly, they are less economical and have lower efficiency. Copper is the most efficient in heat transfer, but also the most expensive.

When replacing the heat exchanger with a new one, pay attention to the thickness of the metal and the weight of the radiator. Quality should not be too light

The high cost of copper leads to the fact that manufacturers save as much as possible on the thickness of the heat exchanger wall, bringing it down to 0.5 mm, which significantly reduces the service life. For the same reason, other metals are added to copper. The alloy obtained in this way may have unpredictable properties. As a result, such a heat exchanger cannot even be soldered.

System water quality

If the water in the system is subjected to frequent chlorination, this will negatively affect the condition of the copper heat exchanger. In combination with the thinned walls of the pipeline, this can quickly lead to corrosion and the appearance of fistulas.

Increased water hardness in combination with heating causes no less problems. Scale deposits require periodic washing.

You can improve water quality using aquafilters and magnetic softeners.

Overheating of the geyser

The most important factor leading to malfunctions and reduced service life of the column is its overheating. It is important not to raise the temperature to 65 degrees or higher.

To reduce the risk of the water becoming too hot, do not use the faucet to cool the water. Only change the temperature using the flame and water flow control knobs intended for this purpose.

Problems with ignition

Why doesn't the gas heater light up? It happens that there is very little gas pressure in the pipes. Look how the gas stove burners burn. Such fuel supply should be reported to the gas service.

Neva and Vector water heaters have electric ignition. If draft, pressure, gas supply are normal, but the column does not ignite, the reason may be the generation of a spark. When you open the tap, a characteristic cracking sound should be heard. We are trying to replace the batteries.

When using hydrodynamic ignition, you should check the operation of the generator. Such repairs will require certain knowledge and skills.

Gas water heater Astra automatic with electric ignition. The reasons that prevent the device from igniting are still the same. It may also not light up if the gas and water shut-off valves are closed. You just need to open them.

Other reasons

The gas water heater lights up and goes out due to a failure of the mechanism that allows access to the gas. This is a solenoid valve and a servomotor. You'll have to call a specialist.

Over time, the tubes in the column may become clogged. You need to make sure they are passable. In case of blockages, special cleaning agents are used.

Burners in gas water heaters often become clogged. Why is this happening? The reason is the accumulation of soot. It is necessary to disassemble the column, remove the burner and clean it with any tools. At the same time, clean the heat exchanger.

The membrane may rupture. It's difficult to buy.

It is necessary to check all the details. Many speakers have electronic components and sensors. For example, in a Neva gas water heater, the draft sensor often breaks down, as a result the device will not light up.

Electronic components will most likely have to be repaired by a technician.

So, you know what measures to take if the gas water heater does not light. We fix many breakdowns ourselves, and in more serious cases we turn to specialists. When repairing a gas water heater, all safety measures must be observed. Always turn off the gas. It is better to clean the gas water heater outdoors.

Features of using speakers

Reviews of Oasis speakers sometimes do not reveal the technical features of the devices. These include:

The presence of a mesh filter, which is mounted on each individual gas burner. It helps prevent dirt from entering the coil of the device.
The manufacturer has installed special corrosion protection for the tank. This is a magnetic filter.
The coil tube is significantly wider in diameter, and its surface has a special anti-scale coating.
The device is safe, as there is a shutdown system in case of lack of water, and there is also a blocker to prevent it from overheating.
The heat exchanger of the water heater is also protected from scale thanks to a special coating.
The device can operate in low pressure conditions.

In general, a gas water heater has enough advantages

It is important to evaluate all the options and choose the device that will meet your wishes and capabilities.

Possible difficulties

Like any equipment, you need to be prepared for the fact that the geyser may also stop working at some point. There are several options in which unpleasant situations may arise:

manufacturing defects;
incorrect installation;
improper operation of gas equipment.

Often in reviews people complain about certain problems. For example, there is no spark in the device. Sometimes reviews complain that the flame goes out if the ignition button is released. Often it is not possible to regulate the gas pressure in the gas water heater; the water heats up to a lower temperature than stated by the manufacturer.

In each individual case, it is necessary to be guided by different criteria when choosing a method for repairing a geyser. Most water heaters come with a 2-year warranty.

The main causes of problems and how to fix them

For those who want to purchase a Vector geyser, there is a useful bonus. It consists in the availability of such a service as after-sales service. If the water heater breaks down, it will be repaired by a qualified technician as quickly as possible. This will be facilitated by the absence of difficulties in purchasing spare parts, the price of which is quite reasonable.

Problems with the Vector geyser can be as follows:

Change in flame color and presence of soot traces. This phenomenon indicates that the device urgently needs cleaning. Of course, this problem cannot be unexpected, because cleaning the water heater from dust must occur regularly. Otherwise, disruptions in its work are inevitable.
Lack of temperature data. They are usually shown on the display. If this does not happen, then damage to the screen itself or the circuit through which the necessary information reaches it is implied.
No response to switching on. This can happen due to weak water pressure (if there is a spark). To solve the problem, you should clean the filter located at the inlet of the water heater or the heat exchanger. In the first case, the cause of contamination will be dust, and in the second, scale. If there is no spark, you just need to replace the batteries.
Reducing the flame until it completely disappears. This fact indicates the need to change the membrane of the water unit.
Spontaneous turning on and off of the device. In this case, you will need to clean the chimney, check the sealing of the pipe and air duct, and eliminate the causes of overheating of the Vector column.
No spark when batteries were recently changed. This will require replacement of faulty spare parts, in particular the microswitch, solenoid valve and (or) electronic control unit.
Reducing the liquid pressure at the outlet of the column. This can happen due to a lack of normal pressure in the entire system, a small pipe diameter and a clogged water filter.
Insufficient water heating. In such a situation, only cleaning the heat exchanger tubes from scale and dust will help.

Carrying out repairs yourself should only happen if you have such experience. If it is not there, you should definitely call a specialist rather than try to fix everything yourself. Such recklessness is fraught with explosion or spontaneous combustion.

According to experts, the likelihood of the problems described above appears due to the poor quality of the parts that make up the water heater, the lack of automatic maintenance of the required temperature conditions, insufficient thickness of the walls of the heat exchanger and the power of the device.

The Vector geyser is a budget option for those who save money in their wallet and do not recognize the need for additional functionality. That is why speakers from this brand have become so widespread. Prices for models with good performance start at 6,000 rubles, which is a good indicator. What are the advantages of Vector geysers?

Affordable price - these are truly one of the most inexpensive geysers on the water heating equipment market;
The simplicity of the geyser design ensures maintainability;
Large model range – buyers have a fairly wide selection of speakers to choose from.

Lovers of good design will also rejoice - especially for the most demanding customers, models with a glass front surface on which various designs are located have been developed. These speakers look just great. As for the quality of the equipment, there are minor complaints about it, as evidenced by the reviews below about Vector geysers.

Next, we will publish reviews of people who have received Vector geysers of various models. Along with the reviews, the advantages and disadvantages of the speakers are described.

Operating principle of an electric heating tank

The operation of the water heating tank is based on the principle of convection:

Cold water always enters the storage water heater from below, and when heated, it rises upward, where the hot water intake tube is located.

cold water enters the tank through the inlet tube;
the heating element turns on and heats the water to the set temperature (there is a regulator on the dashboard with which the temperature is set);
thanks to convection, hot water rises independently to the top of the tank;
the hot water outlet tube is located at the top of the device, through which the heated liquid enters the pipeline;
when the water temperature in the tank drops, the thermostat turns on the heating element, and when it reaches the maximum, it turns off.

it-yourself repairs are carried out in the same way for both the 80-liter Thermex water heater and the 50-liter Thermex water heater . Their design is identical, only the tank volumes differ.

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.

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.

Technical characteristics of VPG 8910-00.02

If you are interested in Astra geysers, then you should consider several models at once so that you have the opportunity to make the right choice. Among others, the VPG 8910-00.02 model, which is manufactured in Russia, is presented on the market. Its power can reach 21 kW. The design is equipped with an open combustion chamber and manual ignition.

The hot water supply capacity is 12 l/min. The supplied water can have a temperature that varies from 35 to 60 °C. During operation, the column consumes natural gas in a volume equal to 2.3 m 3 /h. The maximum water pressure can be 6 bar. The lowest operating water pressure is equivalent to 0.5 bar.

Gas connection is carried out using communications that have the following parameters: 3/4 inch. Hot and cold water connections are made using pipes with a diameter of 1/2 inch. The chimney diameter reaches 120 mm. If you are considering Astra geysers, then you should definitely be interested in their dimensions. As for the model described in the section, its dimensions are 700x372x230 mm. The equipment weighs 15 kg.

Features of repairing old models

First of all, you need to determine why the geyser slams and makes noise when you turn on the water, and if all of the above shortcomings have already been eliminated, but the cotton still persists, then you need to check the functional condition of the product.

Let's start by looking at simple samples of equipment with wicks that are used to ignite a flammable mixture.

In such models, a loud popping noise often occurs when the design parameters do not match the flame contours. Timely ignition of the burner does not occur if the fire size is small or too large. The cause of this problem is considered to be mechanical clogging of the nozzle holes. Through these holes, a dosed supply of gas is formed.

Old models of geysers break down. The cause of the popping sound when turned on is most often a clogged nozzle, burner, or lack of traction

To troubleshoot the problem you will have to do the following:

The main casing is dismantled in order to provide full access to all internal components of the column. The block where gas and air are supplied (many manufacturers use this structure) must be disconnected from the pipe system. Next comes cleaning the nozzle. The most commonly used wire is a soft type of metal. It can be copper or aluminum

The procedure is carried out carefully, so that the calibrated hole is not damaged. Assembly is performed in the reverse order, paying special attention to the integrity of threaded connections and seals.

The jets may become clogged in the main burner. With such a blockage, switching on is also carried out with a bang. When disassembling the device, you need to remember that some components and elements, for example, gaskets, valves, thermocouples, are not very durable, so they must be handled extremely delicately.

Powerful hood

This failure is especially dangerous for devices operating with open combustion chambers using natural circulation, when the vacuum is set by the height of the chimney, and air is taken from the room in which the column is located. When a powerful exhaust system is located in the house, opposite the gas water heater, when it is turned on, flue gases from the combustion space do not enter the atmosphere through the chimney, but are drawn in by the hood.

Additional Information! This leads to a drop in vacuum, separation of the torch from the burner, activation of the flame sensor and emergency shutdown. It will not be able to turn on until the exhaust devices are stopped. To prevent this type of failure, it is prohibited to connect them when the Oasis equipment is operating.

Typical problems

Most often, owners of a gas water heater have to deal with the following situations.

The heat exchanger is clogged

Due to high water hardness or too high water heating temperature, scale will form in the heat exchanger over time. This necessitates regular washing of this part with descaling agents (at home, a solution of lemon juice is most often used). If you notice that warm water flows with low pressure, while cold water pressure is high, then this is a sign of a blockage in the heat exchanger. Also, if there is excess scale, the column may not turn on at all or turn off after a short period of operation.

For another way to clean the heat exchanger, see the short video below.

Water does not heat up to the required temperature

Having discovered this problem, first of all you should make sure that the power settings of the device are correct. If everything is in order with the settings, the cause of insufficient water heating may be contamination of the heat exchanger (both internally due to scale and externally due to excess soot) or the incoming water temperature is too low (this is typical for the winter period).

The column does not light up.

The most common cause of this situation is insufficient ventilation, which can consist either in contamination of the ventilation shaft (soot accumulates in the chimney over time, and foreign objects can also get in), or in the lack of sufficient air flow into the room (for example, after replacing windows). For battery-powered devices, the situation when the device does not turn on at all is usually associated with the batteries being completely discharged. In addition, the equipment will not turn on if the water pressure is too weak (this also applies to gas pressure), the membrane is damaged or there is a gas leak. In these cases, the operation of the speaker will be prevented by the device's security system.

The following video tutorial will help you replace the membrane in the water block of the column yourself.

The burner of the device goes out during operation

Such a malfunction may be caused by a problem with the temperature sensor, worn out membrane in the water unit, poor draft, or failure of the electric valve.

Leak from heat exchanger

This problem is typical for low-quality parts in which copper is combined with various impurities. In places where there are impurities, the surface of the heat exchanger oxidizes and over time, fistulas form there. For this problem, a radical solution would be to replace the heat exchanger, but in many cases the part can be soldered using a soldering iron (if the damage is minor) or a gas torch. You will find information on how to do this yourself in our article “How to solder a gas water heater?”.

Elimination of traction disorders

To test traction, try using an ordinary match. Bring it to the chimney and determine if there is a draft, then the flame will deviate towards the chimney.

If there is no draft, the gas water heater will not light and users will not receive hot water. Many dispensers are equipped with draft sensors, and if they show insufficient draft, ignition will be impossible. Situations are possible when the flame lights up and immediately goes out - this is due to the fact that the combustion products simply have nowhere to go, they remain in the combustion chamber, and the flame goes out due to lack of oxygen. Lack of draft will require an inspection of the flue gas collector and the chimney itself. If there are blockages here, they can interfere with the normal passage of combustion products. The column perceives this as a lack of traction and does not allow the gas to ignite (or the gas goes out immediately after turning on). Unfortunately, you will be able to independently check only the part of the chimney that is visible before entering the wall - further work must be carried out by specialists. If the house is private, you can try to figure out the chimney yourself.

Possible malfunctions of the “frog”

The body of the water regulator is durable and designed to operate at high water pressure (flow rate up to 3 m3/hour). There are few parts in the water unit that can become unusable and cause breakdowns of the gas water heater.

Possible malfunctions:

membrane rupture;
violation of the integrity of the plastic plate - the membrane cannot move the rod;
scale formation on the rod, slowing down the movement of the rod or leading to its jamming, which occurs due to leakage of the oil seal;
destruction of the retarder ball (very rare, but it happens), clogging of the channel, jamming of the ball;
the filter mesh is filled with debris, which reduces the water pressure due to blocking the passage;
debris getting into the Venturi fitting due to which the pressure in the hot water tap decreases, the column does not work;
wear of gaskets and seals is the cause of leaks leading to scale formation.

Most of these malfunctions have characteristic symptoms that can be identified during an external examination.

Leakage of the oil seal gasket leads to the formation of scale and souring of the rod. All scale should be removed. Unscrew and clean the bushing, replace the gasket and seals, clean and lubricate the rod

Any leaks require intervention, which should not be delayed for long. Prolonged exposure to water oxidizes contacts. As a result, the microswitch becomes irreparable and completely unusable.

Verdict

In most cases, the Thermex water heater can be repaired independently, since it has a fairly simple design and operating principle. The main causes of failure are a non-working heating element or scale . This is what you need to pay attention to first. If the boiler does not heat the water well, do not rush to run to the store and buy a new heating element. Perhaps the old one is simply covered with dirt and just needs to be descaled. If the water heater leaks at the joints or the water in it cools down quickly, you will have to buy a new device.

When purchasing spare parts, do not be lazy to take broken parts to the store. This way you will definitely buy what you need.

Malfunctions and methods for their elimination

Despite the proven reliability of the equipment, breakdowns still occur.

The wick goes out. In this case, it is necessary to check the draft on the side of the device, and if necessary, clean the chimney from combustion products. If the problem persists, it may be in the electrical part. It is necessary to examine the contacts of the electrical circuit using special equipment and eliminate the violation.

The pilot and main burners do not light up. In this case, it is necessary to check whether the gas tap is in the correct position.

It is also worth paying attention to the thermocouple fitting - if it is loose, tighten it. You may need to replace a water line membrane that is torn or stretched.

The igniter nozzle may be clogged; in this case, cleaning is necessary. It may be necessary to adjust the position of the thermocouple sensor so that it is surrounded by the pilot flame. Another simple reason is that the inlet water pressure is below the operating range. If all of the above does not work, then the fault may be in the solenoid valve.

There is no water pressure at the outlet. It is necessary to check the pressure of incoming cold water. Another common cause is the accumulation of scale on the filters. This will require cleaning. It is recommended to entrust the removal of scale in the heat exchanger tubes to a specialist.
The main burner burns poorly, which is why the water does not heat up to the required temperature. This means that the gas filters and nozzles on the main burner are clogged - you need to clear them of debris.
Water is dripping. In this case, you can try replacing the gaskets at the joints. But if the heat exchanger has worn out - corrosion and cracks have formed on it - you will need to either seal the heat exchanger or buy a new one. It is worth noting that applying solder to the leak site gives a temporary effect, and sooner or later there will be a need to replace the element.
When you turn on the water, you hear a popping sound from the main burner. This happens because the gas pressure is low, or the plug holes and igniter nozzle are clogged.

Internal breakdowns

The following can happen to the water heater itself:

The ignition system does not work

It is quite possible that there is no damage.
If the spark is generated by batteries, their life may have been exhausted.

Experience shows that the batteries in the speaker have to be changed approximately once a year, even if the manufacturer promises a longer service life.

The igniter column may go out due to the fact that the user did not hold the forced gas button long enough when starting. The safety element did not have time to warm up properly and fix the gas valve in the “open” position.

Water heater is not configured correctly

The required performance of the column depends on the temperature of the water entering it. In winter, the water in the water supply cools down and the gas regulator on the device has to be opened a little more. But in summer the water temperature rises by several degrees, so the column needs to be screwed down. But users sometimes forget to do this. As a result, the water heater turns off almost immediately due to overheating.

In order not to have to worry about adjusting the column before each season, choose a model with a memory function for summer and winter mode settings.

The membrane of the water unit has failed

This is already a breakdown. The following could happen to the membrane:

loss of elasticity due to aging;
the appearance of cracks or deformations;
overgrowing with lime deposits.

Having disassembled the water unit, the membrane must be inspected, and if its appearance is clearly far from normal, the element must be replaced.

The heat exchanger is clogged

To increase the efficiency of the heat exchanger, it is made from a tube with a small flow area. And if the water contains a large amount of hardness salts, this element will soon become clogged with scale. It is quite possible to remove it yourself. In this case, it is advisable to use a product designed specifically for speakers - then the heat exchanger will not have to be disconnected.

It is not necessary to use a purchased composition; you can prepare it at home by dissolving 100 g of citric acid in 0.5 liters of water.

Soot has accumulated on the heat exchanger

This phenomenon leads to a deterioration in traction, to which the safety system reacts. The easiest way to remove soot from the heat exchanger is with a vacuum cleaner, for which you must first remove the casing from the column.

The main or pilot burner is clogged with dirt

You can guess that the igniter is clogged by a weak flame with a yellow cone at the top. The main burner may burn partially if there is dirt. In such a situation, you should call a technician who will clean the burners or, if necessary, replace them.

Characteristics and subtleties of using Oasis gas speakers

The Oasis gas water heater is quite well known to domestic consumers. The wide demand is explained by the attractive price of the device and its full adaptability to Russian gas networks. The device belongs to the middle class heating equipment and is considered a worthy example of an impeccable balance between quality and cost.

Junkers gas water heater: wick does not light (video)

If the column goes out, then don’t rush to call a repairman right away! Perhaps by understanding the essence of the problem and identifying its cause, you will be able to fix the breakdown on your own. But if it doesn’t go out when you turn off the water, it’s better to contact the gas service.

A gas water heater is a very necessary thing in a room where there is no general supply of hot water. Everyone wants to use hot water, but it’s just the central hot water.

Gas water heaters can vary in quality, material, economy and efficiency. Nowadays, many use heating hot water indoors.

Any owner of a private apartment or house has thought about connecting gas heating. Many people are very keen on this as it is considered one of the.

Reasons for attenuation of gas-powered speakers Oasis and Vector

Every piece of equipment, no matter how high-quality or expensive it is, breaks down over time. For example, if a branded Oasis gas water heater ignites and goes out, the reason for this may be a weak fuel supply, a broken ignition wick, a wick, or other problems. This can turn into an accident - a household gas explosion, fire, poisoning by combustion products, so every owner of such a unit needs to know how to identify and eliminate the problem.

Even very expensive equipment after a certain period of use can break down or completely break down so that it cannot be repaired. The reasons for this are very different, sometimes the problem occurs due to poor operation of the gas installation, poor assembly of the device, decreased productivity of the device, etc.

Even with very careful treatment of a gas-powered dispenser, it may stop working well; this very often happens with cheap Chinese equipment. Whatever the cause of the problem, you must remember that gas-type water heaters are a unique device that must be repaired with skill.

If the owner of the house does not have experience in this area of life and the proper tools, then it is better to call a professional to the house. This will make it possible to save time, protect yourself and your family members, because low-quality repairs or careless attitude towards breakdowns can result in fire, poisoning by combustion products, explosion and other troubles.

There are many reasons for customer complaints about the performance of gas water heaters, ranging from damage from mechanical factors, poor operation and other man-made factors, ending with low quality equipment or wear of some parts. Depending on the cause and complexity of the problem, you can fix it yourself, for example, in the case of smoking and fading of the device, or you will have to call a specialist if it is impossible to remove the damage yourself.

Likewise, there are 2 reasons why the wick does not want to light. Owners of gas-type heaters from the manufacturer from our country “Neva” very often encounter a similar difficulty.

The reason for the failure of the ignition wick may be the lack of draft in the chimney, due to which the electronic inspection system automatically stops the supply of fuel. It is very simple to check whether this was actually the cause of poor ignition. You need to bring a lit match to the hole with the rod. If the fire does not move, then the chimney is blocked. This indicates that it needs urgent cleaning, because dust and other construction or household debris regularly collect there. Plus, you should carefully inspect the roof for the presence of third-party antennas or devices for receiving satellite signals installed by craftsmen.

If there is no ignition spark when igniting the gas installation, this indicates damage to the piezoelectric element. Another common cause is dead batteries, because there are many models of water heating equipment on the market that run on rechargeable batteries. For example, devices from the manufacturer “Junkers”. To eliminate the problem, it is enough to replace the power parts.

What to do if the gas water heater goes out for other reasons

In addition to the problems listed above, other problems may appear that negatively affect the operation of the column. You can also deal with them on your own.

To prevent the gas water heater from rotting, there should be no drafts in the room

Other reasons for column extinction:

The column will not ignite if your water pressure is weak or the batteries are dead. New batteries and increasing the pressure can help get rid of the problem. It is also possible that your ignition wick is clogged, in which case it needs to be cleaned.
It is also possible that the membrane tissue has exhausted its own resource. In this case, it needs to be examined. After that, clean or replace.
Maybe your module boards are burned out. To prevent this from happening, connect the speaker through a stabilizer.

If the speaker goes out when you release the button, then your neighbors’ satellite dish may be installed above the chimney. In this case, you need to reduce the flame or turn off the device and contact gas services.

Care tips and advice

For long-term operation of the gas water heater, you need to follow the important recommendations of experts:

Monitor the temperature of the heated water so that it can be used without diluting it with cold water in the mixer.
To purify cold water from hardness salts, it is enough to install a water filter in front of the column.
Carry out regular, annual cleaning of the column and flue ducts from soot.
It is not recommended to disconnect the speaker's electronic systems from electricity during periods of inactivity, such as at night. Frequent power outages lead to disruptions in electronic circuits. This is why false protection and device shutdowns occur when there is no spark at the gas water heater or it goes out.

Effective and durable operation of equipment depends on its correct selection and proper installation. However, even with this, the speaker user may encounter malfunctions, which most often occur due to prolonged operation of the unit, and there is nothing to worry about, you just need to know what to look for.

How to install and configure?

Thanks to the clear and simple installation diagram, the location and connection of the device to the water supply system can be done on your own. Still, only a master has the right to perform all work related to gas communications and adjustment of the column. Before you begin the installation process, you must obtain permission from the gas service and undergo training. One of the very important conditions for installing equipment that runs on gas is the size of the room and the presence of ventilation or chimney. In rooms whose volume is less than eight meters3, the installation of any gas appliances is prohibited.

The speaker cannot be placed above a stove or other sources of open fire. The wall on which the device is supposed to be installed must be fireproof, made of a material that does not support combustion. When installing on your own, great attention must be paid to the tightness of the fasteners and carefully check the quality of the connections after installation work. The equipment is also configured by gas service professionals, testing all modes and purposes of the device.

Radiator leak

Heat exchangers made of copper and copper-containing alloys have the greatest risk of leakage. The reason is that manufacturers often use alloys in which the percentage of copper is lower and lower.

During operation, as a result of corrosion and mechanical damage, small holes begin to appear, violating the tightness of the radiator. These are the so-called “fistulas”. In these places, the heat exchanger begins to let water through.

By the way, even a high-quality copper heat exchanger is not protected from rapid destruction.

Corrosion occurs under the influence of stray currents that arise in the water supply when the dispenser is not properly grounded or when other operating rules for gas-using equipment are violated.

Elimination: you can replace the heat exchanger with a new one, but this will cost a third of the price of the column. Often this is not justified; it is much easier to solder it without disassembling the entire column and removing the radiator.

Before you start soldering, you need to drain all the water from the radiator, otherwise heating the pipeline will be problematic.

To do this, you need to turn off the water supply to the column, disconnect the incoming pipe from the pipe, place a container under it, and open the hot water tap.

When the water has drained, it is necessary to blow through to remove residues. You can use a vacuum cleaner or compressor. If such devices are not at hand, you can blow through with your mouth.

To do this, you need to select a rubber hose of suitable diameter and fit it tightly onto the coil, strengthen the connection by crimping.

Soldering can be done in two ways: with a gas torch or a soldering iron.

Gas burner:

For soldering you will need a torch with a gas cartridge, a sponge, flux paste containing tin and copper, and solder.
Start by heating the leaking tube to evaporate any remaining water. Clean the soldering area with a sponge. Apply flux paste. Heat again until the flux color changes from gray to silver.
To prevent flux residues from leading to corrosion, it is necessary to remove them with a damp cloth.

Soldering iron:

Prepare a powerful soldering iron of 100 W or more, POS-50, POS-61 or other solder with a melting point of at least 200 degrees.

Flux: rosin or solder fat, you can also use aspirin tablets. Using a hair dryer makes warming up much easier.

The soldering area must be cleaned with a zero polish until all traces of corrosion are removed from the metal surface. Then degrease it with alcohol or solvent.

Heat the soldering area well with a soldering iron. Additional heating with a hair dryer gives excellent results. Tin the soldering iron tip with a piece of solder.

Apply a small amount of flux to the soldering area and immediately tin the metal surface with a soldering iron. Try to maintain the fluidity of the solder by adding flux from time to time. Bring the solder thickness to 1-3 mm.

With good heating, a thin layer of solder is enough to reliably eliminate a leak and prevent destruction of the pipeline at the soldering site.
