Masters involved in the repair of heating equipment, highlight the typical problems of some popular modifications of gas boilers.
Key malfunctions of gas heaters “Bosch”:
- Mistakes in the process of ignition of the main burner.
- Various leaks.
- Turning off the heater during operation.
- Frequent problems with the solenoid valve. If the mixer is improperly adjusted, it does not operate steadily.
- Reduced gas supply due to clogged burner device, the nozzle must be thoroughly flushed.
- No ignition at normal gas parameters, due to breakage of windings of gas shutoff valve.
- Excessive noise during the operation of the speaker, due to the damage of the modulator spring, which makes vibrating sounds. To restore performance, either the spring or the modulator must be replaced.
The reasons why the Ladogas heater does not ignite:
Causes of problems with starting the speaker
In normal condition, the water heater is almost silent and operates with a delay of no more than 1-2 seconds after the water draw point is opened. Here are the main signs, which help to diagnose the cause of failure and troubleshooting.
Piezo element does not give a spark
One of the common problems. The malfunction can manifest itself in several ways:
- No spark in the gas column. cause: failure of the piezo element, electrode or its displacement. A similar malfunction is observed when the piezo element does not turn off (approximately 30 sec.). The ignition wick then goes out. Repair if the piezo igniter does not work, is to replace the unit.
- There is a spark, but the heater ceased to ignite. the reason, elementary failure to follow the rules of operation. Before pressing the ignition button, keep the gas knob pressed for about 10 seconds. There is a safety system inside the water heater. As long as the igniter is not heated up, the gas supply to the burner is blocked.10 seconds of pressing the knob is usually sufficient to light the wick. If the piezo element does not work, although the spark is present, read the manufacturer’s instructions and light the wick according to the following instructions.
- The wick does not burn. the breakdown is due to the failure of the automatics or insufficient draft in the chimney. The cause of malfunction is also a soiled igniter, which must be cleaned. Soot settles on the appliance during combustion. The spark is present, but the wick stops burning immediately after the forced gas supply is turned off. Cleaning the igniter (must be serviced every year) will help eliminate the problem.
Replacement or adjustment of the piezo element requires the necessary tools and skills. For repair, it is better to use the service of service shops, or invite the master at home.
Lack of power igniter
Even good quality batteries, if the heater is used intensively, last only 6-8 months. After that the heater begins to work improperly.
Lack of sufficient water pressure
In the technical documentation of water heaters is clearly specified capacity. The minimum pressure at which the heater should work is given. If the burner does not turn on at a low water pressure, the cause is not always due to equipment malfunction. The problem may lie in non-compliance with specifications. The operation can be normalized by installing a storage tank and a booster pump.
With automated heat generators, battery-operated or mains-powered, low water pressure causes the water frog to malfunction. The principle of operation of the regulator is that inside its cavity is divided into two parts by a membrane. In one of the chambers, there is a rod that regulates the gas supply and enables ignition of the burner. The rod is set in motion by the pressure of the diaphragm. If the pressure is insufficient, the rod remains in place and consequently there is no spark in the automatic gas burner, and the gas supply to the burner is closed.
The first sign of damage: the gas water heater does not ignite immediately after turning on the water, but after a while. The water may then begin to leak. Causes of malfunction:
- Diaphragm is stretched. there is a rubber diaphragm inside the assembly. The seal is under constant pressure. Even high-quality rubber stretches little by little and this leads to the fact that the burner lights up only at high water pressure. If the diaphragm is stretched, the frog does not leak.
- The diaphragm is ruptured. in this case, the gas boiler does not ignite the first time. It turns on when the valve is opened again. Tripping time increases. A characteristic sign that the diaphragm has failed is the leakage of the water unit.
- The diaphragm is coarsened. the gasket is made of elastic rubber, malleable enough to press on the rod at the required fluid pressure. The diaphragm becomes coarse when the water quality is low. For this reason, the water assembly loses sensitivity, the gas heater does not ignite properly.
There are protrusions on the spindle in the water unit for moving the ignition lever. If the speaker does not ignite with the batteries (especially if the batteries have been recently replaced), and when you open the tap of HTW the piston rod is stationary, it means that the diaphragm is out of order.
Smoke Removal System Problems
To check the draught is possible with a special hole provided in the speaker. When it’s normal, you can even feel the circulation tactilely. Your hand will feel the air flow into the hole. You can bring a lit match. The flame will deviate significantly to the side of the speaker.
Repair of gas-consuming equipment must be carried out by a specialized organization that has experience, the appropriate license and authorization.

Hello dear readers. If your gas water heater does not immediately ignite, there is no need to panic. After all, the solution to this dilemma can be quite simple. In severe situations, the help of a handyman is required.
When it doesn’t turn on right away, the user has questions about the cause of the problem. And there is a whole complex of reasons. And it is addressed in this material.
How to understand why the gas water heater “Neva” does not turn on?
There are situations when you urgently need hot water, but the column as if by chance does not turn on. Usually if you have an automatic water heater, just open the tap and almost immediately hot water starts flowing. But when problems occur, no matter how much you open or close the faucet, the site won’t light up. Unfortunate.
But to decide whether to invite a specialist or to remove any “trifle” on their own it is necessary to understand the cause of the problem.
The boiler lights up at the second or third attempt
The device sometimes have to be turned on several times, so it does not turn off on its own. The gas water heater “Neva” does not ignite, what causes it?
Cause 1. Batteries. The reason for automatic speakers lies in the batteries, the charge of which is enough only to ignite the fuse, and for normal operation. no. When the batteries start to run out, the clicks are often “idle”.
Reason 2. Filters. They become clogged, and the water does not come properly.
Cause 3. Low draught. In this case, the speaker ignites a little later and with a pop. In such a situation, the ventilation valve will help.
Reason 4. Dislocation of the ignitor plug or microswitch. The latter is checked with an ohmmeter. If it turns out that the necessary values are not achieved, the part is replaced.
The igniter candle is installed with a gap of five mm, first loosening the screw. The burner starts at the first ignition attempt.
The Neva gas water heater does not turn on: the igniter (wick) goes out
The igniter that should ignite the burner ideally operates continuously after being switched on. It heats the thermocouple that leads to the burner, and it ignites. But in certain faults the site does not light up, and shutting down the burner with the sensors serves as a protection. Otherwise there is a risk of gas poisoning.
To understand the cause of damping, consider how the thermocouple works. The thermocouple is powering the solenoid valve by generating an electromotive force. It is caused by heat from the wick. When it begins to produce an electromotive force, the rod enclosed in the valve begins to move and let gas into the burner. But when the igniter goes out, the part stops heating and the rod works in the opposite direction: the valve closes and gas does not flow into the burner.
Why does the igniter not light?? Sometimes the insulation of the conductor of a thermocouple consisting of an alloy of several metals is broken, the conductor comes off, and the thermocouple does not work. Unfortunately, a soldering iron won’t help. The sealed part will not conduct electricity. Have to replace the assembly.
Wick extinction also occurs because of a strong draft or when there is no gas supply. To make sure that the part is okay, test it with an AA battery. Connect the igniter to it. If the light is on, it means it works.
Consider a few more reasons why the wick does not light:
- If you don’t have an automatic model and you have a piezo igniter, you might not hold the button down enough. Increase the hold time by a few seconds.
- The room is not properly ventilated. To cope with the problem, install a ventilation valve.
- Not enough water is flowing into the speaker. It may be a problem with the faucet. But it is possible that the filter in front of the Neva is clogged.
If you are dealing with a Neva Transit, if there is a problem with the ignition, it will display error E1. Perhaps the length of the spigot, where it goes, is too long. Then just try again. Another reason. lack of draught. Light a match and hold it up to the window to make sure it is lit. The flame bends to the side. there is a draught; if it doesn’t, there is a problem.
The “Neva” boiler does not ignite, although there is a spark: the burner does not work
Usually in automatic machines, the speaker is immediately triggered when the faucet is turned on. But it happens that the water heater “Neva” doesn’t light up, when you open the water.
Reason 1. Most likely there is a clog in the system. Magnesium and calcium salts precipitate on the radiator during the exploitation time, and that leads to thermal insulation. As a result more gas will be lost and the water will be heated less. It is possible to clean the radiator from the salts at home. To do this, remove the cover from the speaker, remove the radiator itself and put it in a metal container quarter filled with water. Pour a solution of citric acid (150 grams per 0.75 liter) into the coil of the radiator.) and boil it for 10-15 minutes. After the procedure the part is flushed with tap water, dried and put back in its place.
Reason 2. There may be soot accumulated in the heat exchanger. You should try to clean the radiator with a brush or vacuum cleaner, previously removing the cover. When the burner is clogged with soot, all nozzles are thoroughly cleaned with a metal brush, after which the connections are checked for leaks. For this you need a soapy solution. If you notice bubbles forming somewhere, turn off the gas immediately and call a specialist.
Cause 3. If the filter is clogged, it is also cleaned from impurities.
Gas water heater “Neva” does not ignite: no spark
It also happens that the column “does not want” to ignite at all. No need to rush to call a specialist right away, because the causes can be the most common, and a specialist may not be needed.
Cause 1. Low water pressure. If it is less than normal, the speaker will not light up. It happens that after some time the pressure is restored. But if it still remains small, it is worth inspecting the filters and pipes leading to the speaker. They are sometimes clogged and therefore the pressure of water flowing through the speaker is reduced.
Cause 2. The batteries are dead. Automatic models run out of battery power over time and need to be replaced. Although, it will probably be enough just to clean the contacts. It is better to install alkaline batteries, as for the operation of gas appliances. this is the best option.
Reason 3. The chimney is clogged and it needs to be cleaned
Reason 4. The pipes are leaking at the joints. To fix the problem, you will need to tighten the nuts and possibly replace the gaskets.
Cause 5. The membrane, which stands at the entrance to the water tank. It can be clogged with scale, wear out, lose elasticity. You will have to change it anyway. The procedure is not simple, because it is necessary to remove the “frog” from the heater and disassemble it, and after replacing the membrane to reassemble it.
Reason 6. The water block is broken. In this case, call a specialist.
The gas water heater does not ignite: causes and repair
Gas stove is a capricious thing. It happens that even a new technology begins to give out “surprises”: it turns off at the most inopportune moment or does not ignite at all. What to say about the old, worn out heater. And it’s hard to do without it. Do not really warm water on the stove!
In case of a breakdown of the speaker call the master, but only he will have to wait, and all this time to do without hot water. Sometimes without the help of a specialist really can’t be done. But often you are able to cope with the breakdown on your own. What to do when the heater does not work? Why the wick or pad does not light up?
Prevention of malfunctions of the gas water heater
In addition to troubleshooting, you need to know how to properly disassemble the gas water heater. These skills are necessary for carrying out maintenance with your own hands. For which you need to know not only the constituent elements, but also the sequence of actions when disassembling the heater.
Carrying out periodic preventive maintenance throughout the operating life of the gas water heater will contribute to the correct operation.
Annual cleaning is recommended in the technical documentation by the manufacturer. After all, it is the lack of cleaning during prolonged use that can lead to all of the above-mentioned problems.
Water flow problem
Often the water heater does not light up when you turn on the water because of the reduced water flow. With such a malfunction in the faucet, the stream of water when turning on is very thin, weak. There is a feeling that the gas water heater is faulty in appearance. Happens with absolutely any brand: Neva, Oasis, Bosch (Bosch).
A reduction in water flow may occur:
Sudden loss of performance of the gas water heater can occur due to street work. At this time, the repair of the street water line can be made. Accordingly, the total pressure of cold water everywhere will be drastically reduced. The owner can easily miss this point and look for the cause in the gas water heater, disassembling it. The reason lies on the surface, but the person is confused and looks for it in something else entirely.
Also, the water pressure in the gas water heater can gradually decrease due to the banal contamination of the aerator designed for the faucet. To exclude the cause of the malfunction associated with the aerator in the faucet itself, it is necessary to remove and clean it.
Electrical For Gas. Ignition Systems
This is a typical aerator that is installed on the mixer. Try to clean it
Owners who have a mesh filter in the inlet, too, should not forget about it and periodically clean.
Coarse filter. It is installed in the supply of cold water in the column. Clean it as well
The filter bulb can also cause a gradual decrease in the water pressure in the gas water heater. It is worth not forgetting about it and, first of all, if the wick of the gas water heater does not ignite, pay attention to this. If you miss the cause, which lies on the surface, there is a risk of investing money in unnecessary diagnosis or repair of the gas boiler. Repair and diagnosis of gas water heater, in this case, is not appropriate.
Two filters for water purification in flasks. They can also be clogged
There is another case related to the lack of water pressure when turning on the gas water heater. This happens because of mechanical clogging of the hose. Dross in the hose was found, and it blocked the way of water. Dust could be coming from the heat exchanger.
There are two regulators in the gas heater. One is responsible for controlling the strength of the flame, the second is responsible for controlling the flow of water. The lower the position of the regulator, the lower the pressure at which the heater can operate.
Signs of a faulty ignition switch
Electric ignition of the gas stove can break down completely unexpectedly, and while using the technique the switch will continue to turn and click, the gas comes out, but the spark will not appear.
If when you turn the switch one or all burners do not ignite, but there is a spark, then the problem is probably not in the piezo ignition system, but in the elementary contamination of the nozzle.
The absence of a spark when turning on at least one burner already indicates a malfunction in the piezo ignition system. There are also frequent situations when gas burners make noise during operation. You can read more about this problem here.
However, it is only possible to find out which part is malfunctioning on the basis of the following signs:
- the electrical ignition function does not work when the burner control knob is pressed;
- the automatic piezo ignition functions work properly, accompanied by clicks, but there is no spark;
- The system does not turn off even if the knob is lowered or the off button is pressed;
- The circuit breaker in the apartment circuit breaker is knocked out when the appliance is switched on.
Often the problem of automatic ignition failure is a complete lack of spark, or conversely, a continuous sparking even when the device is switched off.
Also, the electric ignition may temporarily fail due to jamming of the start-up buttons, provoked by the accumulation of grease on the control panel. The problem can be eliminated by cleaning and drying all components of the gas stove, including buttons and contacts.
How does the electric ignition of the speaker work??
Electric ignition unit can operate from different power sources from batteries or electricity. Gas water heaters with this type of switching are called “Automatic”.
The ignition unit requires two thick 1.5W batteries. To make them last for a long time, it is recommended to use LR20 high-capacity alkaline batteries.
The disadvantage of battery-powered ignition is that the batteries must be replaced all the time. You should always have a reserve of batteries, so that you can quickly replace them.
Electric ignition from the water turbine speakers are equipped less often. Hydroturbine generates an electric current as the liquid flows through it. Water gets into the element when you open the hot water tap. This type of device is much more convenient than a battery-operated device, as it does not require permanent replacement of batteries. However, the disadvantage is the need for a good water head. not less than 0.3 bar.
