Despite the fact that the technologies for supplying hot water and heating to multi-storey and private residential buildings are constantly developing, gas water heaters are still installed in most apartments. Often, users of these devices may encounter a problem - the column goes out after some time of operation, or it refuses to light up at all. Such problems with such equipment are not uncommon. Let's find out why the geyser goes out and how to fix it.
Device
Before you repair the column, you should find out how it works. In most cases, the method of repair also depends on the design. We will not delve into the structure of each individual column. But general principles everyone should know House master. To avoid such annoying breakdowns, you need to choose the right gas water heater flowing. Reviews are the best indicator of quality. Users write pros and cons, and you can navigate them when buying.
Centralized hot water supply systems appeared relatively recently. Previously, the issue of heating water was solved by the most various methods. The most common solution was the so-called accumulative solid fuel heater - "Titan". This system was heated with coal or firewood and fuel oil. The water in the boiler of this equipment had to be preheated. So, to take a bath, it took from one hour of time to heat the water. Naturally, it was very, very inconvenient to operate such a system. The problem of the time required for heating was solved by the creation of gas water heaters. People gladly accepted and began to operate the flowing gas water heater. Reviews about this equipment are positive. But this applies only to high-quality Bosch, Burning, Zanussi devices.
So, a typical geyser heats up an ordinary running water gas from the main. In order for the heating process to be fast, a heat exchanger is used in the design. In it, water is distributed through thin tubes located directly above the burner. Due to this, you can heat the water very quickly (almost instantly). The consumer does not need to accumulate it in special tanks.
This is the basic structure of a standard column. Everything else in the design serves to ignite the fuel, adjust the temperature of the liquid heating, and ensure the safety of work. gas device.
Columns by type of ignition
The column lights up in different ways. It depends on the particular design. When ignited by an igniter, the gas is ignited either by piezo ignition or manually by matches. This is true for older models. The igniter burns constantly.
There are also columns where there is no igniter, but instead there is a piezo ignition. And finally, there are solutions with an electronic ignition system. This system is structurally similar to the ignition system of cars. Works automatically.
Protection systems
In most gas water heaters, which are in many apartments and houses, mechanical system security. Even the most modern unit, in which there are many electronic sensors and devices, has a mechanical connection between the membrane in the water supply system and the valve installed in the gas pipe.
Gas will be supplied only when the force of water pressure is sufficient to press on the membrane. The principle here is very simple. If there is no water, then gas will not be supplied to the burner of the column. If you turn off the tap and the water flows, the column will light up.
Common Problems
Let's look at why the geyser goes out. Attenuation can be caused by a number of reasons. A sensor may turn on that detects a gas leak. There may be problems with the operation of the chimney. A clogged pilot also often causes damping problems. Sometimes the automation fails.
Often the problem of attenuation is also related to the quality of the fuel. Some gas facilities do not supply pure gas, but diluted. Such low-quality fuel is easily determined by orange color flame. If there are serious automatic protection systems installed in the column, they will turn off the system.
You should also pay attention to gas leaks. Even minor leaks are the reason why these units fail. Help can repair gas water heaters at home. But you should only contact professionals - gas is no joke.
Weak or absent traction
Among the main reasons for such unsatisfactory work may be weak draft, or its complete absence in the ventilation duct. However, one of the most popular reasons is a locked plastic window. As a result, there is no air flow. The column will overheat, and eventually the thermal protection relay will trip. If you open a window or door, and the column lights up and does not go out, in this case the cause is related to overheating.
Clogged chimney
If too much combustion products have accumulated in the chimney or there are foreign objects inside, then the protection system will work in the heater system, which will shut off the gas. You can check for what reasons the geyser lights up and goes out in this case, as follows. It is necessary to open a window or window, light a match, and then attach it to the hole in the chimney. If there is no thrust, then the flame will not deflect.
You can eliminate insufficient draft or its absence by cleaning the chimney and ventilation duct. In this matter, it is best to contact specialists who, for a small amount, will clean the chimney with high quality.
Dead battery
Another reason why the geyser goes out is the batteries. If the column is equipped with an auto-ignition system, and it is powered by batteries, then it is recommended to replace them. Also in this case, it would be useful to test the button responsible for starting and shutting down.
Water node problems
The next column is the absence and weak pressure of water. When opening a faucet with cold water the pressure of its supply will be insufficient, then this is the problem of the supply companies. Because of this, the gas column goes out. What to do? You need to understand the reasons for the low pressure.
If cold water is supplied with greater pressure than hot water, then such column operation is associated with the water part of the unit. Among the reasons are clogged filters, membrane deformation. Often the reason lies in the fact that the hot water supply pipe is clogged. If there are additional filters (if they are clogged), the water pressure can also be significantly reduced.
How to troubleshoot?
The first thing experts recommend doing is cleaning and washing the filters. It is better to completely replace the cleaning elements with new ones. If the reason is related to the water part, you should call the public utilities and find out from them why there is such a weak pressure in the system. Often problems are solved by cleaning the pipes and the column itself. The membrane may also need to be replaced. If you have questions about the gas part, it is better to use the service "repair of gas water heaters at home".
Professional craftsmen will carry out repairs as safely as possible.
The column lights up and goes out
You can hear about these cases from the owners of this equipment quite often. You can fix the problem by adjusting the volume in which hot and cold water is supplied. It is not recommended to dilute excessively hot water by adding cold. This will lead not only to an extinct flame, but also to a violation of the rules for operating the unit. To adjust the water supply, reduce its level in the tap.
Conclusion
So, we found out why the wick in the gas column goes out. After all faults have been corrected, gas unit, which makes life more comfortable, will work stably.
Geysers are widely used due to their availability, high performance and economy. Not only the comfort of the residents, but also their safety depends on how well the gas water heater works. After all, like any equipment consisting of many mechanical parts, the gas column is subject to wear and tear.
The reasons for the incorrect operation of a gas water heater can be associated with both external factors and malfunctions of the internal components of the device. Only correctly identify the problem, it can be quickly and effectively eliminated.
External factors affecting the operation of the gas column include:
- Mechanical damage to the equipment power cable;
- Insufficient ventilation draft;
- Low pressure in the system;
- Too strong or too weak gas pressure;
- Low water temperature;
- Incorrectly connected pipes;
- Discharged batteries.
In order to diagnose ventilation, you will have to remove the pipe to remove combustion products leading from the geyser to vent. After that, thrust can be measured with a special device - an anemometer.
Low water pressure in the system (in apartment building) can be associated with both the supply itself and the clogging of the pipes.
To understand what the problem is (pipes, or insufficient pressure in the system that does not squeeze out water), you need to contact the housing office. It is the housing maintenance office that should monitor the health of the plumbing in your home.
Among the internal factors affecting the operation of the water heater, there are:
- Depreciation of the elements of the water intake unit (clogging of the inlet filter, deformation of the water block membrane);
- Clogged heat exchanger tubes;
- Malfunction of gas supply valves;
- Deterioration of the solenoid valve or servomotor;
- Ionization sensor failure (electrode contamination).
In addition, after long-term operation, owners of gas water heating equipment often encounter a clogged ignition wick. What to do if the gas water heater stops working correctly?
The geyser ignites poorly: how to troubleshoot
Most of the most common faults that affect performance gas equipment, can be quickly eliminated with your own hands.
Concerning external factors, then you can independently adjust the supply of gas and water, clean the internal pipe to remove combustion products.
Water pressure can be increased using a special pump. Chimney - check for breaks, clean from dust. If the draft has not increased, then special workers will have to be called in to clean the ventilation ducts.
In addition, if:
- After diagnosing the condition of the equipment, a clogged inlet filter of the water intake unit was detected, it is necessary to clean the part with a large pressure of water or replace the filter;
- The water block membrane has ruptures or the gasket is stretched to one side - replace the part (in this case, it is better to put a new silicone membrane, the service life of which is longer than that of rubber);
- The automatic column does not turn on and, at the same time, the power indicator does not light up - replace the batteries;
- The column ignites poorly and with pops - clean the ignition wick (if this does not work, then replace solenoid valve or servomotor)
- The column works for several seconds, after which it does not light up, even if the ignition sparks are frequent - clean the ionization sensor electrode.
What to do if gas does not enter the gas column
If the main burner of gas equipment does not ignite, there is no characteristic sound and smell, then most likely gas is not entering it. Why might this be happening? First of all, you need to check the gas shut-off valve: it must be open 90 degrees.
In addition, fuel may not enter the dispenser due to low pressure in the gas distribution system. You can solve this problem by contacting GORGAZ: gas workers can raise the pressure in the pipeline up to 300 mm of water column.
The problem of fuel supply to the gas water heater may be due to improper connection of the column to the gas pipeline.
So, embedding a gas water heater into a gas pipe should only be done through a special tee. If the gas is supplied through a flexible hose, you need to make sure that the connection is tight. In addition, the hose must not be kinked anywhere: this can create a situation that is dangerous to health and life.
Why the geyser does not ignite Vector
Problems in the operation of the gas column Vector are most often associated with water quality. So, hard water can cause scale on the heat exchanger, clogging of the filter of the water intake unit, nozzles (often found in Amin gas columns). These problems are solved by cleaning clogged parts. In addition, the column may not ignite due to deformations of the inlet membrane, the water reducer rod (it may turn sour). Owners of domestic Astra speakers may also face the same problem.
Both the stem of the water reducer itself and the ring-gland on it can wear out. You need to start replacing from the last one.
Owners of Bosch speakers with piezo ignition are often faced with the fact that when the equipment is turned on, the igniter goes out. Most often this is due to the dustiness of the element. In order to fix the problem, you need to blow out the igniter tube and use a thin wire to clean the hole in the nozzle through which gas is supplied to the igniter.
This problem is most often encountered by owners of Aquaheat equipment. In addition, the power of the batteries may simply not be enough for the correct operation of the equipment. In any case, the batteries will have to be changed.
What to do: the geyser does not light up (video)
Geyser- this is affordable equipment that allows you to quickly and efficiently heat water for both heating systems and domestic use. The comfort and safety of the residents of the apartment depends on the proper operation of the gas water heater. But do not panic if the geyser is broken: most problems can be easily fixed with your own hands. You just need to correctly identify the problem. And the above tips will help in this!
It is far from always possible to fix malfunctions due to which the gas column does not light up when the water is turned on. Some breakdowns require the involvement of a specialist. On the other hand, the cause of problems in the operation of the water heater is not always associated with the failure of internal components and modules. You can fix minor damage with your own hands.
Causes of problems with starting the column
To identify the malfunction and eliminate it, it will be necessary to analyze the operation of the equipment. Masters pay attention to the following signs:- there is no spark from the piezoelectric element or the igniter does not work;
- the burner ignites, but not the first time or periodically goes out;
- the water regulator (frog) is leaking;
- column turns on with a pop.
Piezo element does not spark
One of the common problems. A malfunction can be expressed in several manifestations:- No spark in the gas column- reason: failure of the piezoelectric element, electrode or its displacement. A similar malfunction is observed in cases where the piezoelectric element does not turn off (approximately 30 seconds). After that, the ignition wick goes out. Repair, if the piezo ignition does not work, consists in replacing the assembly.
- There is a spark, but the column has stopped igniting- the reason, elementary non-compliance with the rules of operation. Before pressing the ignition button, it is necessary to keep the gas supply knob pressed for about 10 seconds. There is a security system inside the water heater. Until the igniter warms up, the gas supply to the burner device will be blocked.
10 seconds of pressing the feed knob is usually enough to light the fuse. If the piezo element does not work, although a spark is present, you should re-read the manufacturer's instructions and light the wick in accordance with the instructions given. - The wick does not burn - the breakdown is associated with the failure of the automation or insufficient draft in the chimney. The cause of the malfunction is also a contaminated igniter that needs to be cleaned. When gas is burned, soot settles on the device. There is a spark, but the wick stops burning immediately after turning off the forced gas supply. Cleaning the igniter (needs to be serviced every year) will help eliminate the problem.
Lack of power to the igniter
In this case, the geyser, powered by batteries or a hydro generator, does not turn on when the water is turned on. A failed water assembly diaphragm (described below) can lead to a malfunction, but more often the cause lies in the following:- The batteries are dead - the spark works, but its power is not enough to ignite the burner. The column does not turn on immediately, it does not light up for a long time, while the electric ignition constantly works. If the battery-powered column does not turn on, stops responding to the opening of a water tap, the first thing to do is to replace the batteries.
- Hydro generator not working- a turbine that generates electricity from the movement of water supplied to the water heater. The unit is sensitive to water quality and pressure. If the hydro generator refuses to work, it is necessary to clean the internal device from dirt and deposits. The problem is solved in 80% of cases. The pressure required for the operation of the turbine is stabilized using special booster pumps for water supply.
- The power supply is a common cause of a malfunction if the geyser with automatic ignition does not light up. The lack of spark is due to power failures. There are several reasons for the malfunction: the contacts are oxidized, the resistors are swollen. With the ability to solder, you can fix the breakdown yourself. Most often, the power supply is simply replaced with a new one.
Even high-quality batteries, subject to intensive use of the water heater, last only 6-8 months. After that, the column starts to malfunction.
Lack of sufficient water pressure
The technical documentation of water heaters clearly states throughput. The minimum pressure at which the column must be operated is given. If the burner does not turn on when the water pressure is low, the reason is not always a malfunction of the equipment. The problem may be hiding in a non-compliance with specifications. You can normalize the work by setting storage tank and booster pump.With regard to automatic heat generators powered by batteries or from the mains, low water pressure leads to the fact that the water unit (frog) does not work. The principle of operation of the regulator is that inside its cavity is divided into two parts by a membrane. In one cavity there is a rod that regulates the gas supply and turns on the ignition of the burner. The rod is set in motion by pressing the membrane. With insufficient pressure, the rod remains in place and, as a result, there is no spark in the automatic column, and the gas supply to the burner is also closed.

Diaphragm problems
The first sign of a breakdown: the gas water heater does not ignite immediately after turning on the water, but after some time. In this case, the water unit may begin to leak. Causes of malfunction:- Diaphragm stretched- a rubber membrane is located inside the assembly. The gasket is under constant pressure. Even high-quality rubber is gradually stretched and this leads to the fact that the burner ignites only with a large pressure of water. If the diaphragm is stretched, the "frog" does not leak.
- Broken diaphragm- in this case, the gas column does not ignite the first time. Turns on when the faucet is opened again. Increases the duration of the operation. characteristic feature the fact that the membrane has become unusable - a water node leak.
- Diaphragm coarsened- the gasket is made of elastic rubber, malleable enough to press on the stem at the required fluid pressure. With poor water quality, the membrane becomes coarse. For this reason, the water unit loses its sensitivity, the gas column does not ignite well.
Problems of the smoke exhaust system
Problems arise after several years of use, due to violations associated with the installation and placement of the water heater, as well as changes specifications space used as a boiler room. The main causes of failures in work:- No draft in the chimney- a common occurrence in old houses. Channels, especially made of brickwork, are destroyed over time. The accumulated debris leads to a deterioration in air circulation and, accordingly, affects the operation of the geyser. Typical symptoms:
- the wick burns, but the main burner does not ignite;
- when the burner is turned on, cotton is observed;
- column spontaneously goes out.
- Installation of metal-plastic windows- PVC windows are airtight and prevent oxygen from entering the room where the column is installed. Lack of air supply causes the water heater to not work or turn off after 3-5 minutes of use.
Finding the root cause of failures is easy. If the column works normally with the window open, then the malfunction is caused by a lack of oxygen, which leads to a deterioration in traction performance. To restore circulation to metal plastic windows install a special inlet valve.
You can check the presence of traction using a special hole provided in the column. In the normal state, circulation is felt even tactilely. The hand will feel the flow of air into the hole. You can bring a lit match. The flame of the flame will deviate significantly towards the column.
The geyser is used to heat water. Devices differ in the type of ignition and in the type of burner. On older models, manual ignition is used. We bring a lit match and open the gas valve.
Piezo ignition works like a lighter, you just need to press the button, a spark is formed. With electronic ignition, the burner turns on automatically. The spark is created from two finger batteries. This is the most modern technology.
Main causes of malfunctions
The device may not work for various reasons. For example, the geyser does not light up. You can immediately contact a specialist. However, with many breakdowns you can handle yourself.
If the device is under warranty, it is better to contact the master. It will determine why the device is not working. Known geysers different manufacturers. Water heaters Neva, Vector, Orion have automatic ignition. At correct operation serve for a long time. The gas column Oasis has a semi-automatic ignition mode.
Geyser Astra has manual ignition. If it does not light up, you need to inspect the heat exchanger - maybe dirt has accumulated there.
The Oasis geyser lights up and goes out for the same reasons as many other appliances: a chimney is clogged, poor draft, a radiator is clogged, water or gas pressure has dropped. Sometimes the cause may be a strong gust of wind, a broken sensor, a mixture of hot and cold water, or a damaged membrane.
No draft in ventilation ducts
Any geyser can clog the chimney. In this case, it turns on protective system. The water heater does not ignite or goes out.
Traction needs to be checked. If sensors are installed, then we look at their readings. In the absence of such devices, open the window and put your hand to the chimney. If you feel a gust of wind, then the traction is good.
Another way to check. We bring a burning match to the chimney. The flame must deflect towards the chimney. If necessary, clean the ventilation. For this, it is better to call the master.
Batteries or generator
This type of malfunction is only possible for devices with automatic ignition. For example, the Neva gas column does not light up (photo). Often, the instructions indicate a larger value for the battery life.
To eliminate the causes of the malfunction, it is necessary to check the power buttons. If necessary, replace the batteries or the automatic dispenser generator.
Some devices, such as the Astra water heater, may have batteries oxidized. Contacts need to be cleaned. The contacts of the electrical circuit are broken. Stem oxidation may occur. It needs to be cleaned and oiled. If the control unit or valve breaks down, they must be replaced.
Decreased water pressure
Any geyser may not ignite if the water pressure in the water supply is small. And if you manage to light it, it quickly goes out. Why is this happening? In this case, the reasons may be different.
It is necessary to open the taps with cold and hot water. Compare pressure. If it is equally weak, then the water supply is clogged.
If the pressure of cold water is greater, then the following malfunctions are possible:
- clogged inlet filters;
- the membrane is deformed;
- clogged hot water pipes.
To troubleshoot, you need to find out in the housing and communal services the causes of low water pressure. Clean filters or pipes if they are clogged. Clean the device from soot. Replace filters and membrane.
Only a specialist technician can clean clogged pipes in the Neva column.
If the water filter is dirty, disconnect the pipe that supplies cold water. There is a mesh filter that needs to be cleaned.
We first try to eliminate a small pressure on the column itself. Some models have such a regulator, for example, in the Oasis water heater and other automatic models.
The homeowner can install a pump that will increase the water pressure. This is a legal operation.
The reasons for low water pressure may be in the improper condition of the pipes that are in your apartment or house. You need to check if they are clogged.
The Orion geyser has gas and water pressure regulators. It shows battery charge, temperature. The device does not go out even at low water pressure. The video shows the principle of operation.
Problems with ignition
Why does the gas column not light up? It happens that there is very little gas pressure in the pipes. Watch the burners burn gas stove. This supply of fuel must be reported to the gas service.
Water heaters Neva and Vector have electric ignition. If the draft, pressure, gas supply are normal, and the column does not ignite, the cause may be in the generation of a spark. When the tap is opened, a characteristic crack should be heard. We are trying to replace the batteries.
For water heaters with piezoelectric ignition, such as the Oasis, you need to check if the igniter is working. If the gas in the igniter does not ignite or goes out, you need to clean the jet. To do this, you will have to disassemble the device.
With hydrodynamic ignition, the operation of the generator should be checked. Such repairs will require certain knowledge and skills.
Geyser Astra automatic with electric ignition. The reasons that make it impossible to ignite the device are the same. It may also not light up if the gas and water shut-off valves are closed. You just have to open them.
Other reasons
The geyser lights up and goes out due to the failure of the mechanism that opens access to gas. It is a solenoid valve and a servomotor. We'll have to call the master.
The tubes in the column can become clogged over time. You need to make sure they are passable. In case of blockages apply special means for washing.
In geysers, burners 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. Clean the heat exchanger at the same time.
The membrane may rupture. It's hard to buy.
You need to check all the details. Many speakers have electronic units and sensors. For example, in the Neva geyser, the thrust sensor often breaks down, as a result, the device will not light up.
Electronic components, most likely, will have to be repaired by the master.
So, you know what measures to take if the geyser does not ignite. We fix many breakdowns ourselves, and in more serious cases we turn to specialists.
When repairing a geyser, all safety measures must be observed. Always turn off the gas. It is better to clean the gas column in the open air.
The operation of any gas device must be monitored very carefully. Notice all the little things and details that have changed when the unit is turned on, during its operation. This will help you to early stages to identify and timely eliminate problems that have just begun, and possibly even prevent a major problem.
What to do if the column does not ignite?
Internal organization geyser -This is the most frequently asked question, which occurs among the owners of gas equipment. Wait to panic - let's understand the situation. In fact, there can be a great many reasons for this - from the most simple and banal, which can be eliminated in 5 seconds, to very serious ones, for which you will need a specialist to deal with.
The very first thing you need to do- see if the igniter is on. If he doesn’t even think about lighting up, then you can’t do without a specialist gas service. He will competently clean the igniter jet, or maybe replace the igniter itself with a new one.
Second probable cause – you simultaneously opened a tap with cold and hot water, and the flow of cold water was much greater. This is what led to the extinction of the flame in the igniter.
No draft in the chimney
You try to ignite the gas, but it just won't ignite. Why? First check the draft in the chimney. It is likely that it is clogged with various debris, and the combustion products simply will not be discharged outside, but remain in the room. In this case, the built-in protective automation of the device simply does not allow it to ignite and does the right thing - it's life-threatening!
Your actions in this case are simple: open a window or window. Light a match and bring it up to the chimney. If the flame does not even make an attempt to deviate, then the chimney is not working. Just call the master to clean the pipe and everything will be in order.
Check the chimney outlet first. Perhaps one of the neighbors installed an antenna above him, so the thrust was gone. By the way, this is forbidden, as it is a potential cause of carbon monoxide poisoning.
Another one possible reason lack of traction tight closed windows in room. Simply put - there is nowhere to take traction. This is especially true if you have plastic windows, and it's cold outside. Of course, you will try to close it as tightly as possible, completely blocking the access to air. If after opening the window the column lights up, then the problem is obviously solved.
Batteries (batteries) are discharged
Batteries for columns with automatic ignition If your unit has an automatic ignition system, then do not skip this reason, even if you bought a column a few months ago. Enterprising manufacturers promise a year or more of work on a single charge, but in reality this is not at all the case - the elements “die” much faster.
What to do in this case: Replace the batteries with new ones and try the power button again. If the column lights up, then the problem is fixed.
How long do you hold the fire button? For the column to function properly, the button must be pressed for at least 20 seconds.! If you hold it less, then the column will go out after a while.
Weak water pressure
The column can only work at a certain water pressure in the pipes. If the pressure is low, then she will not even think to turn on.
What to do in this case: open cold water in another room. If the water also flows “sluggishly” there, then the problem is in the water supply system. You just have to wait. If the water flowed very “briskly”, then the problem is already in the unit itself.
Filters or membrane?
If the device went out after turning on, then the point here, with a high degree of probability, is in the temperature sensor responsible for overheating the column. In this case, 2 scenarios are possible:
- The column lit up, worked for 10-15 minutes, after which it went out, and all attempts to kindle it did not lead to anything. After some time, it can be turned on again, and after 10-15 minutes the story repeats itself and again in a circle. The reason is a too sensitive overheating sensor. It detects too high a temperature around the column and turns it off. In general, this is a factory marriage, so if you wish, you can give it for service.
Remember that this problem can only appear in the middle of summer, when it's hot, or in winter, when all the windows are closed. You'll be lucky if your purchase's warranty hasn't expired by then. Otherwise, the repair will have to pay out of pocket.
- Unit shutdowns do not have a pattern - it may not turn on, then work properly, and then turn off again. If this situation is familiar to you, then the cause may be a frayed sheath of the sensor conductor. The bare part closes to the body and the safety valve is turned on. Who to contact in this case? To a service center or to the manufacturer of the model. The gasmen will not help you here, as this is not their part. And with your own hands, you are unlikely to be able to fix anything.
How to remove scale from a column
All internal components of the geyser This problem occurs frequently. Its consequence is a weak pressure of warm water from the tap.
What to do in this case: you need to clean the heat exchanger (its replacement is carried out in very neglected states). And if you yourself cannot carry out the replacement, then cleaning it is quite up to you.
First, let's look at the reasons why scale occurs. Everything is very simple - the water in our pipes flows very hard, with large quantity lime. When the water temperature reaches 80˚С, it settles on the walls of the heat exchanger. Conclusion - try to use very hot water as little as possible - above 80 ° C. After all, even greasy dishes can be washed at 45 ° C.
Many people leave the column igniter on, as it is convenient - you do not need to constantly turn it on. However, after 1 hour the temperature of the water in the heat exchanger will reach 85˚C and higher. Therefore, we advise you to always turn off the column after use.
If you still need to clean it, then you have to arm yourself the following equipment:
- open end wrenches;
- Screwdrivers;
- rubber hose;
- Paronite gaskets;
- Descalers (e.g. acetic acid).
Step 1. Shut off the water and open one hot water - at the point that is closest to the column.
Step 2. Remove all fittings and cover from the column.
Step 3. Disconnect the hot water hose from the radiator and lay it aside. Wait until all the water has drained.
Step 4. Put a hose on the heat exchanger and very carefully start pouring an acid solution or other agent through it. Do not pour in a large amount at once, otherwise a very stormy chemical reaction. Leave for at least 2 hours.
Step 5. Place a basin or other container under the tap and open it. If there is a lot of sludge in the water and the pressure is restored, then the problem is solved. If not, we recommend doing the procedure again.
For more information about cleaning the heat exchanger, you can watch the video:
The column turns on with pops
There are 2 reasons for this phenomenon:
- Too much gas pressure. As a result, the burner ignites too actively and the flame breaks off with a corresponding sound.
- Too little gas pressure. air enters the burner and the resulting gas-air mixture explodes, producing mini cotton.
What to do in this case: call the gas service worker to clean the burner. Do not do this procedure yourself!
The column heats the water incorrectly
You ordered hot water, but the water is barely warm? Check the power of the unit you have chosen - it is quite possible that according to its technical specifications the model is simply not capable of more.
Second Possible Solution– stop opening several taps at the same time (kitchen, bath and shower).
Third option- The burner is clogged. Checking this is easy - the color of the flame instead of the correct blue has become yellow. Call a specialist: 1 hour of work and the column will again work with a bang.
Smells like gas when turned on
This is the most dangerous scenario. It means that some connection is leaky. If you feel even the slightest smell of gas when you turn on the device, then immediately shut off the gas supply pipe, turn off the column, ventilate the room and call the brigade (104).
In no case do not try to figure out the reason yourself!
Geyser is flowing- how to solve a problem?
One of the most frightening malfunctions: after its manifestation, you immediately want to rush to the store for a new radiator (it is he who flows). However, its cost will make you think - can you do it yourself? And you will be right (if, of course, you have at least basic soldering skills).
So, we need:
- 2 screwdrivers (flat and Phillips);
- Open-end wrenches;
- A vacuum cleaner;
- Sandpaper;
- 100 W soldering iron - less is not recommended.
- Solder;
- Solvent (acetone or alcohol);
- Rosin - it can be replaced with a regular aspirin tablet.
Disassemble the column and find the damaged area of the radiator. Most often this is a pipe on the outside of the heat exchanger. After detection, drain the water from the radiator of the device (open the hot water tap and unscrew the nut from the unit pipe that supplies water to the column - the water will drain itself due to the difference in levels. Blow out the rest with a vacuum cleaner).
Clean the place of work with sandpaper, and then wipe it with a solvent or any alcohol-containing liquid. This will degrease the pipe material. Solder, by the way, can be absolutely anything, and rosin (or aspirin) is a flux.
When the damaged area is already covered with solder, then increase the thickness of the layer to 2 mm. If you see a "green" place, then this indicates one thing - there is also a tiny crack that needs to be soldered.
Remember! For any doubt about own forces It is better to leave repairs to qualified personnel!
Prevention of geyser problems
We will give you some tips that will not only extend the life of the column, but also help to avoid many of the problems described above.
- In the room where the column is installed, there must always be an air supply. A window, a window leaf during the operation of the device should be open even in winter.
- Never! Do not mix cold and hot water. In general, this is considered a gross error in the operation of the column, which leads to the formation of scale and a reduction in operating time.
- Choose gas hoses with a length of less than 3 meters. Otherwise, the gas pressure becomes very small, which can also cause interruptions in operation.
We wish you trouble-free operation of your geyser!
