Repair and maintenance of gas water heaters Electrolux GWH 275 SRN (RN), GWH 250 LEN, AEG GWH 11 RN, Vaillant MAG pro OE 11-0 / 0.

These geysers were produced by the Spanish plant Fagor and are the most successful of a similar model range. The control is fully hydraulic with a permanently lit igniter. Automation is based on the speed of water flow through the water unit.

During ignition, the control knob is set to ignition, the pusher of the handle axis presses the solenoid valve. Next, we press on the piezoelectric element, a spark jumps into the ignition burner and ignites the flame.

It is necessary to wait about 10-20 seconds and turn the knob into the operating mode (summer or winter). The pilot flame heats the thermocouple, which generates a voltage of about 30 millivolts to hold the electromagnet in a clamped state. The gas unit is brought into working order.

The column is waiting for the opening of the tap with water. As soon as water begins to flow through the water unit, the activation rod moves up and opens the gas supply valve to the burner. The burner is ignited by the pilot and the water is heated. After turning off the water, the water unit returns to its original state, the burner goes out, the igniter continues to burn.

It consists of separate units of a traction interrupter, a heat exchanger, a burner with a gas supply train and nozzles, a gas unit, a water unit, a thermocouple, an ignition burner. Gas and water units are collapsible and repairable.

For repair, the outer protective casing is removed and a visual inspection is performed. The shroud retaining screw is located under the lower handle.

Leakage can be due to burnout and corrosion of the heat exchanger, wear of the seals and oil seals of the water unit.

There were isolated cases of not turning off the gas burner after closing the water tap. Due to the lack of heat removal, the water in the heat exchanger boils, vaporization occurs and, with the release of steam, melts the parts of the water unit (between the metal half-shells, the units of the water unit are plastic).

Replacing the original heat exchanger does not cause any difficulties. There are heat exchangers of Russian production in Tula, Iva-Service LLC. In the absence of a heat exchanger, a heat exchanger from GWH285 can be installed on the GWH275. There is no need to make changes to the structure, only it is necessary to install a 3/8 ″ extension about 40 mm long between the outlet of the water unit and the inlet of the heat exchanger (in the photo it is assembled from a 1/2 ″ barrel and two adapters).

The stages of repair are shown in the photographs.

Sometimes, when the gas handle is installed in the ignition position and the piezoelement is pressed, the igniter does not ignite. The igniter can be lit with a match. This defect is caused by an incorrect position or contamination of the spark plug and, less often, a malfunction of the piezoelectric element. The presence of a spark, you can see it, and clean the candle and bend the electrode. When the button falls out of the body of the piezo base, the button can be fixed with a ring.

Another malfunction - after igniting the pilot burner, and after waiting for the required time for the thermocouple to warm up and turn the knob to the operating position, the igniter goes out. This breakdown can be caused by a malfunction of the solenoid valve of the gas unit, disruption (oxidation) of the contact between the solenoid valve and the thermocouple, malfunction of the thermocouple, malfunction of the thermostat of the gas control system (soldered to the thermocouple wires and checked by a jumper) and malfunction of the valve of the gas unit.

In the valve of the gas unit there is a plastic cylinder with a groove for moving the axis and when the groove is worn, the valve does not function correctly.

The next possible breakdown is when, when the igniter is on and the gas valve handle is in summer or winter mode, after opening the water, the burner does not ignite.This is a malfunction of the water unit, internal blockages of the filter, vias, tubes inside, damage to the membrane.

Another possible malfunction of the water unit. The stem of the water unit hangs in the upper position due to a breakdown of the water flow valve, which seizes the piston of the stem.

Note the small tab on the membrane. It is responsible for smoothly turning on the gas when the water tap is opened (the flame should increase for 2-4 seconds), and instantaneous off when the tap is closed. If the membrane tongue does not adhere tightly to the lower half (does not cover the via of the Venturi tube) of the water unit, then when you turn it on again, the column will give out a portion of boiling water. All malfunctions of the water unit are eliminated by its bulkhead or replacement.

In May 2017, a repair kit for a water unit manufactured by Nizhny Novgorod appeared. The repair kit includes rubber rings, a membrane, a lubricant. The repair kit can be purchased from us.

The extinction of the column during its operation is associated with clogging with soot in the heat exchanger or weak draft and insufficient air flow into the room. At a nominal gas consumption of 2 cu. meters per hour, about 25 cubic meters of air are needed, naturally, when installed in a small room without providing air flow, the gas column will go out.

We diagnose the Aeg geyser by phone, so the cost of this service for you is

Automatic ignition device:

• Check whether the batteries are installed in a special hole and are used to ignite the column.
• Open the gas cock.

• Set the power control relay to maximum.
• In order for the column to start its work, it is necessary to open a hot water tap on one of the faucets in the apartment. If suddenly it does not turn on, re-open the valve after 15 seconds.
• Check if there is a flame.

The amount of gas consumed can be adjusted using a relay located on the control panel (indicated by a flame icon). To increase the power, you will need to turn the relay counterclockwise and vice versa to decrease it.

The temperature is regulated using a regulator (indicated by the temperature column icon), which is located on the control panel. To increase the temperature and decrease the pressure, turn the relay clockwise.

Please note that the cold water shut-off valve on the riser must always be fully open. It is forbidden to regulate the fluid pressure using it.

If you know that the device will not be used for a long time:

• Shut off the gas supply.
• Remove the batteries from the device.
• Close the cold liquid stopcock.
• Set the temperature control relay to the minimum value.
• Open the gas valve.
• Drain the liquid by opening a special valve.

To ensure trouble-free operation, it is necessary to clean it once a year. If you need to replace worn parts, use original parts when replacing, but if you use others, you automatically void the warranty for the device.

So, you need to check:

• System for the removal of carbon monoxide.
• Clean the burner and gas nozzles. This can be done with a brush.
• Clean the heat exchanger.
• Assess the condition of the ignition and reference electrodes.
• Make a soapy solution and see if the gas joints are airtight.

In order to turn on the unit, you need to drown the knob that regulates the gas supply and turn it clockwise to the position where the asterisk is drawn. When we have set the lever in this position, it is necessary to press the piezo ignition button and hold it for about 7 seconds, until a stable flame appears.

If you are turning on for the first time or after a long period of inactivity, during which the gas was turned off, then you need to do the following. Turn the switch to its lowest position before you hear a click, so that the gas mixture fills the entire pipeline.

Gas column piezo ignition button

You may have to wait about 15-25 seconds, depending on its duration, and then set it to the asterisk position and use the piezo ignition, which is located at the bottom of the column.

After switching on, you must wait 15 seconds for the safety valve to operate. Then you can set a comfortable heating mode using the gas control relay.

In the instructions for the AEG gas water heater, the presence of two operating modes is prescribed: summer is indicated by a low flame, it turns on when the entering water temperature reaches 10 degrees. As a rule, this is from April to October, winter is marked by a high flame.

If the device is turned off due to inadvertence and you need to start it again, you need to wait 5 minutes until the safety valve turns off.

Regardless of the mode that you have chosen for operation, economy or normal, you can still change the heating temperature. Rotating the relay to the left to decrease, and to the right to increase.

When the work is stopped, it is necessary to turn the gas power regulator relay clockwise. Thus, you cut off the gas supply to the ignition group.

The device is not intended to be in subzero temperatures. Therefore, it should be installed in heated rooms. If, nevertheless, this is not possible, it is necessary to drain the water from the system. You can read how to do this above.

Gas water heater in the bathroom

Scale is one of the main problems of this device, due to its accumulation, a decrease in the flow of water is observed, a decrease in the temperature of heating the liquid.In order to minimize its accumulation and formation, it is necessary to heat the water to a temperature not higher than 45 degrees. If, however, you notice signs of its accumulation, clean up immediately.

This type of cleaning must be carried out at least once every 12 months, to clean the main burner you will need:

• Close the gas supply, remove the cover of the apparatus.
• Clean nozzles with a brush or a brush, blow off residues of fine dust and debris.

Gas column ignition burner

The pilot burner needs to be cleaned when the flame has changed to orange, normally blue-blue. So, we perform the following actions:

• We shut off the gas supply, remove the casing, unscrew the nuts to remove the burner and nozzle.
• We blow out the ignition burner tube and clean it.
• We also clean the nozzle.
• We put everything in its original place.

If the device does not light up, the following malfunctions are possible:

• Not enough gas. Check if the gas is open, if yes, it may have run out in the cylinder (if it runs on liquefied gas).
• Air ingress into the gas pipeline. Can be eliminated by opening and closing the valve.
• Defective batteries. Perhaps they are discharged, or there was a mistake during installation and they were installed incorrectly. The batteries may have leaked.
  Installing a gas column battery

Check the correct installation, if they are damaged, clean the socket where they were and install new ones. This malfunction can only be with devices with automatic ignition.

Insufficient water pressure. It happens that the pressure of cold water is much less than that of hot water. There are two ways out - either install a pump that will increase the flow, or adjust the heating of the water so that it does not need dilution.

Poor cravings. It is very simple to check it, substitute a burning match or candle to the chimney, if it sways, the chimney is normal and the problem lies elsewhere. And if not, then cleaning is needed, you can do it yourself or contact a special service.

The AEG gas water heater is a product belonging to one of the most famous German brands. All modifications have one schematic diagram, which today the developers considered to be as close as possible to perfection. The devices are designed to meet any domestic hot water needs of the owner. And most importantly, German water heaters, unlike their Chinese counterparts, not only heat water: they are able to maintain its temperature constant - without this, using the services of a water heater cannot be comfortable.

Allgemeine Elektrizitats-Gesellschaft is short for AEG, a company founded by German engineer E. Rothenau in 1833. The logo design was invented in 1896. Since 1909, the company was headed by the Russian inventor M. Dolivo-Dobrovolsky, who created a three-phase transformer. Since 1994, the AEG department for household appliances has been merged with Electrolux. Today the headquarters of the concern is located in Germany, and its wholesale base is in Belgium. The company has representative offices all over the world. It is the largest German brand that sells household appliances on the world market.

The manufacturer does not need to praise the product - AEG products have long been known in Europe and beyond. The equipment of this brand is an example of safety, quality and economy. Plus a sleek, stylish design that rivals might envy. Features and benefits of a technical nature:

• Thanks to the simulating burners, there are no temperature differences at the outlet - they change the intensity of the flame depending on the pressure in the water supply pipes.
• Reliable security system. The developers have provided several levels to exclude the occurrence of dangerous situations. Help to avoid dangerous situations:

- draft sensor (from overheating of the upper part of the apparatus);

- thermocouple (from the spread of gas in case of accidental extinction of the flame);

- hydraulic valve (against overheating of the device).

The equipment is equipped with special safety valves - if the burner goes out during operation, they, when triggered, cut off the fuel supply.

• Fuel consumption regulation. Works without readjustment in the gas pressure range of 13-20 mbar.
• Combined fittings. This unusual design solution allows you to solve the most common malfunction that occurs with such devices - a leak at the pipe connection.
• The formation of scale in the tubes of the heat exchanger is prevented by means of special turbulators. The absence of limescale allows you not to lose the heating rate.
• Automatic ignition to ensure complete combustion of the incoming fuel.
• Temperature regulators are provided.
• Gas fired water heaters are more economical than boilers. "Blue fuel" is the most profitable energy resource today.
• Compactness. Easy to fit in the cramped kitchen.

There are two designs of AEG water heaters:

• Flowing. Low cost price. Compactness, simplicity of the device.
• Accumulative. The principle of their operation is similar to the flow-through counterparts, the difference is the storage capacity. They cost slightly more flowing ones.

By the type of combustion chamber there are:

• Open. Works when connected to a chimney. Combustion products are removed by natural draft.
• Closed. A ventilation turbine is installed that removes the exhaust to the outside.

Models can also differ in power, color, design.

The main parameter when choosing a water heater is its thermal power. The volume of heated water depends on this indicator. The smaller it is, the fewer water intake points the device can serve. For a modest consumption, 18-19 kW is enough. Based on the use of several water consumption points, you need to choose a model from 24 kW.

As befits a good column, the heat exchanger is made of copper, and the burner is made of stainless steel. Type - flow-through. Construction details:

• Electronic ignition saves fuel consumption.
• We need a natural draft chimney.
• Thanks to the modulation of the flame, its intensity is quickly regulated, ensuring the stability of the outlet temperature.
• Two mechanical controls - power and temperature.
• 2 modes - full and economy.
• Several levels of security. Gas blocking when the safety valve, thermocouple and draft sensor are triggered.
• Adaptation for low pressure in water supply pipes - ignites at 0.5 atm, and for low gas pressure - 13 mbar.
• Two years warranty.

• Power 20 kW.
• Heating range 25 - 73 ° C.
• Productivity is 11 l / min.
• Weighs 11.6 kg.
• Fuel consumption - 2.1 m3 / h.
• Dimensions 65.4x35.4x24 cm.

Classic instantaneous water heater - with vertical installation and bottom connection. The ignition method is piezo ignition. Open combustion chamber. Safety is ensured by the gas control system and temperature limitation. AEG GWH 11RN characteristics:

• Power - 19.2 kW.
• Productivity - 11 l / min.
• Dimensions 31 × 63.4 × 23 cm.
• Weighs 10.9 kg.
• The inlet pressure range is 1-10 atm.

More powerful in comparison with the previous modification. It's bigger and heavier. Weight - 14 kg, and dimensions - 35 × 72.2 × 29 cm. Piezo ignition. Open camera. Technical specifications:

• Inlet pressure - 0.5-10 atm.
• 24.4 kW.
• 14l / min.

Reliable safety system - gas control, overheating protection and heating limitation.

Structurally, AEG water heaters do not differ from their competitors. When the user opens the tap, the reducer acts on the valve, gas flows to the burner and ignites it. Heating starts. She moves along the coil. There is a hot stream at the exit. When the water supply tap is closed, the valve returns to its original position, the flame goes out. Devices with an open combustion chamber are called atmospheric. They consist of:

• metal case;
• burners;
• igniter;
• heat exchanger;
• copper coil;
• automatic gas supply valve;
• water reducer;
• piezo ignition systems;
• branch pipes supplying gas and water supply pipes;
• chimney and combustion products removal systems.

The turbocharged models - with forced exhaust extraction, have design features:

• Modulating type burner - it can change the strength of the flame automatically.
• The fan, controlled by the electronic unit, blows air.
• Auto ignition - provided by batteries, a hydrogenerator or an electrical network.
• A sensor that controls water heating. The maximum value is 60-70 ° C and depends on the model.

Do-it-yourself gas equipment repair is possible only if the breakdown is insignificant. Before any intervention in the device, it is necessary to familiarize yourself with the instructions - it is not enough to be able to use it, you need to delve into the principle of operation and design. If the malfunction is serious, have it fixed by a service center. The most common problems are:

• The column does not light up. The probable cause is a breakdown of the ignition system or a clogged igniter. Disassembly is needed here, followed by repair or cleaning. It is better to entrust it to a specialist. You can independently eliminate the lack of draft associated with a clogged chimney.
• Attenuation of burners. Probable reasons - the temperature sensor or the emergency shutdown system is faulty. What is the reason for this? Perhaps - a factory defect or a violation of the operating rules, which provoked a breakdown. Another option is poor cooling due to improper installation of the device. In any situation, the intervention of specialists will be required.
• No hot water or poor flow. Reasons - the burner is idling, causing the heat exchanger to overheat. It needs to be cleaned or replaced. Details about the heat exchanger on the page "Heat exchanger for gas water heaters, repair, cleaning".

Self-disassembly and cleaning of the equipment is strongly discouraged by the manufacturer and specialists in its repair and commissioning. Unless you can change the battery without the help of specialists, entrust the rest to the service center.

• Start by checking the functionality of the batteries that fire up the device.
• Open the gas valve.
• Set the power control relay to maximum.
• Open one of the hot water taps. Doesn't turn on? Reopen the valve after 20 seconds. Check for a flame.

• Power. Using a relay located on the control panel (marked with a "flame" icon), the gas flow is regulated. To increase the fuel supply, you need to turn the knob counterclockwise, decrease it - vice versa.
• Temperature. It is adjusted by a regulator with a corresponding mark - "thermometer". Turn the regulator clockwise to increase heat and decrease head.

Important! The valve on the cold water riser must always be in the position - 100% open. It is forbidden to adjust the fluid pressure by turning this valve.

• Shut off the gas.
• Remove the batteries from the compartment.
• Close the cold water shut-off valve.
• Set the temperature regulating relay to the "minimum" position.
• Open the gas valve.
• Drain the heat exchanger.

In order for the equipment to work flawlessly, you need to clean it every year, and, if necessary, change parts that have failed. It is recommended to use original spare parts for replacement, otherwise you may lose your warranty. During preventive maintenance, check and perform:

• How the waste gas system works.
• Cleaning of burners. The nozzles are cleaned with a brush.
• Cleaning the heat exchanger.
• Condition of electrodes - ignition and control.
• Tightness of gas joints using a soapy solution.

Turning on begins with turning the gas supply regulator - by drowning it, and turning it clockwise to the "asterisk" mark. Having put the handle in this position, press the piezo ignition button with a hold for 7-8 seconds - until a stable flame appears.

When you turn it on for the first time or after a long downtime with the fuel supply turned off, they act differently: the relay is turned to the position at least until it clicks - so that the entire pipe is filled with the gas mixture. You need to wait 20-25 seconds. Then put the regulator in the "asterisk" position and turn on the piezo ignition. After waiting 15 seconds - for the safety valve to work, set the desired mode by adjusting the gas supply.

The thing is not for a long time. Five years later, it started flowing in two places at the same time. If the head is small, this model will not work - it will not ignite. I had to change the pipes, only then they were able to wash normally. Cons - noisy, even expensive batteries have to be changed very often. Cheap ones sit down in a couple of days. When you turn it on, a crackling sound is heard and boiling water pours for a couple of minutes - you have to stand and wait for a normal one. Not designed for two points - low-power. On the plus side, it looks good and the control knobs are comfortable.

Connected after three years of inactivity in the package. But it lit up without problems. Works flawlessly. Warms well. There are 2 modes - maximum and economy. In an ordinary apartment, there is even a lot of it - quite enough for several consumers. If there is one bath and a kitchen, then even in the economy mode, its power is too much. Plus - a temperature machine. If you turn on another tap, the water practically does not lose heat. Easy ignition. Cons - the wick burns all the time. There is no heating indicator. Plus - it is not afraid of splashes, humidity, can be installed in the bathroom.

Gas water heaters from AEG are simple and reliable, easy to operate. These are worthy representatives of European quality. Safe and inexpensive equipment ideal for everyday use. The appearance of problems is usually associated with violation of operating rules and physical wear of parts. Due to the presence of an extensive service network, maintenance, adjustment and repair of AEG speakers does not cause any difficulties.

Any professional will tell you: "a gas water heater is a potentially dangerous equipment, so you can only entrust its maintenance and repair to a qualified specialist." However, the ability to understand which element is out of order and what it can lead to will definitely not hurt.

DIY geyser repair

In addition, you can deal with the elimination of some malfunctions that do not specifically affect gas equipment on your own. Read the description of typical breakdowns and recommendations for action in case of their detection.

Gas column device

Equipment can stop igniting for several reasons.

Gas column device

First of all, you must make sure that the igniter is working properly. If it does not light up, contact your gas service. A specialist will clean or replace the failed element. You cannot touch it yourself - it is dangerous.

Gas column device diagram

In modern units with electronic ignition, in the absence of ignition, gas ceases to be supplied - it is cut off by a valve. The user becomes aware of this through the corresponding indicator. In some situations, this problem can be solved by simply replacing the battery. Check this point in the instructions. If the manufacturer does not give such recommendations, it is better to immediately contact the gas service or a third-party repair service.

At one point, the column may not light up

Battery pack for igniting the column

The column will not light up if there is no ventilation draft. To check the level of traction, we bring a strip of paper to the ventilation grill. If the leaf does not change its position or does not change it clearly enough, there are obvious problems with craving. In apartment buildings, utilities are engaged in cleaning ventilation wells - contact them.You can do this yourself with the help of a metal brush tied to a flexible wire (hose, etc.) of a suitable length, however, utilities usually do not approve of such unauthorized actions.

Burners often fail to fire due to diaphragm wear. This structural element deforms rather quickly, the burner starting mechanism becomes less sensitive and does not work when the water is turned on. Even in expensive heaters, membranes wear out in 5-8 years - unfortunately, nothing can be done about this.

Often burners do not fire due to diaphragm wear

To check, turn on the water to maximum. If the column turns on with a strong pressure, the problem is definitely in the membrane. Replacement of this element can be done on your own.

To do this, do the following:

• unscrew the fastening nuts from the water unit (usually there are 2 of them);
• unscrew the fastening screws, due to which the water unit is held in the gas unit (usually 3 screws);
• detach the halves of the assembly and you will see a rubber membrane. If it is not flat but noticeably deformed, replace it. To do this, buy a similar product from a specialized store. If possible, give preference to a silicone membrane - it will last much longer than its simple rubber counterpart.

At the same stage, you can check the condition of the water intake filter. If it is clogged, clean it or replace it with a new one. To clean, simply unscrew the nut from the water supply side, take out the mesh and rinse it or replace it with a new one, depending on the condition.

If the heater turns on but goes out, the problem in most situations is the bimetallic temperature sensor needed to protect the equipment from overheating. Also, due to malfunctions of this element, the heater may not turn on at all.

This problem has 2 main development scenarios.

1. According to the first scenario, the burner lights up properly, the equipment functions for some time without any complaints, and then goes out and for some time does not show any signs of life - attempts to ignite the heater do not lead to anything. Usually, after 20-30 minutes, the equipment turns on again and history repeats itself. This is due to the excessive sensitivity of the sensor. As a rule, it is "congenital", i.e. this is a factory defect. It is extremely difficult to do something on your own. It is better to immediately contact the manufacturer's service for warranty repairs.
2. According to the second scenario, the column may turn off randomly, and sometimes not turn on at all. The reason usually lies in the wear of the insulating material of the conductor of the bimetallic sensor. There is a banal short circuit to the case, as a result of which the safety valve is triggered, and the column begins to behave abnormally.

Contact the service center for warranty repair

It makes no sense to turn to gas workers - the defect is clearly not a "gas" one. You also don't need to try to get rid of the breakdown yourself - you can only break the unit. Contact the service center for warranty repairs.

Water comes out with a weak pressure

Most often this happens due to clogging of the column heat exchanger with scale. Prolonged “idle” ignitions of the igniter are usually the cause of clogging. The device heats up the heat exchanger to a temperature sufficient to cause the remaining moisture to evaporate.

There is no water flow, scale is not washed out of the heat exchanger, until the next turn on of the equipment, it sets, as a result of which the column ceases to function normally. Cleaning the heat exchanger usually saves. In advanced cases, it has to be changed.

For replacement, it is better to immediately contact the professionals, but you can handle the cleaning on your own. Prepare screwdrivers, rubber hose, open-end wrenches and paranite gaskets. Purchase a descaling mixture from a hardware store. Usually it is called that - antiscale.A more budgetary option is rinsing with vinegar essence. Work in this order.

First step. Remove the fittings and the casing from the heater one after the other.

Second step. Turn off the inlet water and open a hot water tap, preferably as close as possible from the column.

Step three. Unscrew the water supply pipe from the heat exchanger and then move it to the side. After unscrewing the nut, the column heat exchanger will begin to release water. In total, about 1 liter of it will be drained.

Fourth step. Place a hose of a suitable diameter on the inlet of the heat exchanger and lift it just above the heater. Insert an ordinary funnel into the fixed hose and start slowly pouring in the prepared solution in a thin stream (instructions for preparation are given on the package). There is no need to rush. If you pour it too quickly, the antikipine will simply push it back out, and you are unlikely to like it.

Flushing the gas column heat exchanger

Leave the cleaning agent in the heat exchanger of the heater for 2-3 hours (usually the required time is indicated on the packaging).

Place a suitable container under the water tap and carefully re-feed the heater. Observe what comes out of the hose. Was there a lot of slurry coming out, and then the head returned to normal? Things are good. Otherwise, flushing will have to be repeated. Usually, the need for re-rinsing arises only when using vinegar essence. In most situations, decalcification works the first time.

In such a situation, it is better to immediately contact a professional. He will perform the adjustment, which is extremely difficult to make without knowledge of the matter, and the column will start working normally.

You can find out the reasons for the appearance of such a malfunction for general development. There are two main reasons:

• the gas is supplied under too high a pressure. The heater ignites too actively, which leads to the breakdown of the fire;
• the gas flow is too low. Air enters the heater burner, resulting in a microexplosion, which is interpreted by human hearing as cotton.

The column does not heat up the water sufficiently

This usually happens due to the insufficient power of the gas column. The user begins to demand more from the equipment than it can do.

There are two options for solving the problem:

• we stop abusing and do not open hot taps at the same time at all points of the water intake;
• buying a more powerful speaker.

Also, inadequate heating of the liquid can occur due to the clogging of the burner. Look at the color of the fire. Under normal conditions, it is bluish. If the flame turns yellow, contact the gas industry. Such repairs can only be entrusted to a professional, tk. this is already a "gas" breakdown.

The problem is more than serious. Don't even think about any hand-made repairs. Turn off the heater, turn off the gas cock, ensure that there is adequate ventilation at all times, and call the gas service immediately. The arriving team will assess the problem and take appropriate action.

Now you know the main malfunctions of the gas column, and you know how to behave when they appear. The main thing is to remember about safety. There is no need to try to fix breakdowns for which you do not have enough qualifications - this can lead to irreparable consequences.
