The presence of a gas water heater in a house or apartment solves the issue of hot water supply. It is easy to use and, as a rule, does not cause problems for users. Therefore, the situation when a water heating device clicks, whistles, or crackles is, to put it mildly, unpleasant, don’t you agree? But what to do in this case?
In this article we will look at the main reasons why a gas water heater hums and also makes other extraneous sounds. Let's talk about when it is necessary to immediately call a specialist, and in what cases you can restore the operation of the device yourself.
Features of the geyser device
To understand whether extraneous sounds are related to problems with the speaker, it’s worth taking a closer look at its structure. Different models have characteristic features, but the principle of operation of any device of this type is identical.
The basis of the geyser is a box, usually rectangular in shape. Inside there are tubes supplying water and gas. Cold water enters the column and passes through the radiator compartment. In it, water is heated under the influence of a flame coming from a burner.
As soon as the tap opens, from which heated water should flow, the valve inside the column is activated and the gas supply is turned on. It enters the combustion chamber, in which the water is heated.
Exhaust gases exit through the chimney (ventilation) duct. Depending on the modification of the device, this occurs on the basis of natural or forced draft.
Natural draft speakers require a chimney of a certain diameter. If it is impossible to install it, install turbocharged speakers. They are additionally equipped with fans to remove exhaust gases through a coaxial pipe. The combustion chamber in such devices is closed.
If one of the nodes operates incorrectly, the protection is triggered and the column is turned off.
This may happen in the following cases:
- there is insufficient draft in the chimney;
- the burner has low heat;
- insufficient water pressure;
- heat exchanger overheating.
Sometimes the speaker continues to work, but at the same time makes various sounds, which also indicate a problem.
Types of filters
They will protect the boiler from the ingress of finely dispersed impurities, scale, and, as a result, the occurrence of noise effects.
The following types of filters are installed on water heaters and the inlet group of the water supply system:
- Rough cleaning. Captures mechanically suspended particles (up to 1 µm).
- Fine cleaning. Ion filters additionally remove small particles of impurities, including metals. Membrane (osmosis method) additionally neutralize chemical impurities.
- Cleaning systems using various adsorbents (physico-chemical method).
The most effective are combined types of filters with multi-stage cleaning.

Strong buzzing
This sound is associated with a violation of draft in the chimney. First of all, you need to check whether the ventilation duct is working. Bring a lit match to it. If there is a draft, the flame will pull into the hole. If there is no reaction, the chimney is clogged and needs to be cleaned.

The humming may be due to a violation of the general ventilation in the room. Absolute tightness is created by closed plastic windows. Therefore, during operation of the column, arrange slot ventilation or open the window slightly.
Prevention measures
Most often, humming and humming in household appliances is associated with its improper installation, operation and maintenance.
The dishwasher is installed in the same way as a washing machine - level, with adjustable legs. It should not be warped, the door should open completely and close without problems. If this is not the case, adjust its position. Always load the basket with dishes as recommended by the manufacturer. The utensils should not touch the walls or touch the sprinklers. You should also not overload the baskets.
After washing, it is advisable to clean the drain filter. This is not difficult to do: it is easy to get out without additional tools. It is worth using dishwasher cleaning products - such household chemicals are available in all stores.
If, despite all preventive measures, the dishwasher pump hums during operation, you need to call a repairman for diagnostics. If you replace one part in time, you won’t have to buy new equipment.
Whistling
Strong or minor whistling can be heard from different places in the equipment. The cause is a pipe connection failure. First of all, it is necessary to accurately determine the location from which the whistle is coming.
The procedure is as follows:
- Close the gas pipe and open the hot water. If the whistling noise continues, inspect the water supply system. When using the column for a long time, limescale (scale) forms inside the pipe. Most often, this is the reason for the whistling. The diameter of the pipe decreases and water passes through with difficulty. To fix the problem, wash the heat exchanger with a special solution, folk remedies (citric acid, vinegar and soda) or replace the part.
The cause of whistling can often be scale
- If the whistle stops after opening the tap, this indicates that the problem is in the gas supply pipe. The flame control valve is probably broken. Reduce burning intensity. Turn the adjuster one way or the other. If the whistle decreases, the device needs to be cleaned.
- If adjusting the valve does not produce results, cleaning the gas pipe is necessary.
Scale formation in the heat exchanger is a common problem that impairs the performance of the column. To prevent this, you need to install a filter at the cold water inlet that reduces hardness.
Water doesn't heat up
Weak pressure of hot water from a gas water heater is not the only problem that water heater owners face. The device may not heat up at all, resulting in cold liquid.
Why is there no hot water coming from the gas water heater:
- Dirty deposits have accumulated on the outside of the heat exchanger.
- The flame is not strong enough to heat. The problem of insufficient gas pressure will have to be corrected. Perhaps clean the parts.
- The heat exchanger is overheating. This violation leads to the appearance of a layer of scale. The normal operation of the device is disrupted. Cold liquid flows.
- The pressure level in gas pipes is low. This is a reason to contact the gas service.
- Lack of constant maintenance and pollution prevention. It leads not only to heating failure, but also to poor water pressure from the water heater.
What to do if cold water flows:
- Turn the regulator all the way to the right. Close the tap halfway. This will slow down the water movement and improve heating.
- Check gas pressure. Only a specialist can do this.
- See how the mixer works. It can add cold water to heated water.
- Determine if the filter or faucet is clogged.
Crackling
A crackling sound when burning indicates clogged injectors. They need to be cleaned by removing the box. If the column crackles and does not light up, the problem lies in the performance of the batteries. The batteries are probably dead and need to be replaced.
The situation is more complicated in devices with electric ignition. There are several reasons for the cod in this case:
- The batteries are dead . The piezo ignition clicks, but does not fire. To fix the problem, just change the batteries.
- The touch gas supply controller has failed . This can occur due to oxidation of the metal under the influence of moisture. You need to clean the contacts or replace the sensor.
- Candle deformation . The device may not work due to the wick being misaligned. Place it in the correct position and the gas will ignite.
- The retarder ball is stuck in the ignition mechanism . Remove the part and shake it to return the ball to the desired position.
In turbocharged speaker models, the cracking noise may be caused by incorrect fan operation:
- The blades are dirty . To clean them, remove the device casing and inspect the fan. If necessary, wash the blades and lubricate the moving elements.
- The winding burned out . If the fan remains motionless after the column is ignited, most likely the contacts have oxidized or the winding has been damaged. Try cleaning the contacts. If this does not help, the fan needs to be replaced.
When does the clicking occur?
How to understand why a gas boiler clicks? As a rule, clicks can be heard when turning a gas boiler on and off. And also during cooling and heating. Below are the most common reasons:
- During startup, a large amount of gas is generated. This gas flashes as soon as the device is turned on, causing us to hear noise.
- The cause of the extraneous sound may be a malfunction of the three-code valve or the ignition mechanism. Also, the reason may be hidden in a clogged chimney. This leads to the formation of a mixture of gas and air. A dirty wick is also accompanied by clicking noises. If the problem is not corrected, cravings will worsen over time.
- Due to incorrectly installed brackets, the balance of thermal expansion occurs. Because of this, blockages occur in the lower part of the boiler body, which can cause extraneous sounds. Often clicks can be heard when there is a large evaporation of liquid.
- There may be malfunctions in the operation of the pump itself; it is necessary to check it for any problems.
- A sharp drop in temperature in the boiler. The device cools down, making characteristic sounds.
- An extremely rare, but still possible cause of clicking sounds is improper installation of pipes.
Incorrect burner installation
Often the cause of noise, clicking or whistling is due to improper installation of the burner. To check, you will need to evaluate the level of gas pressure leaving the burner and the recommended indicators in the equipment instructions.
The appliance is noisy when heating water
Modern boilers operate silently, so vibration, noise, and other sounds are a cause for concern. Why does a gas boiler click? What could be the reason:
- Incorrect installation and configuration.
- The elements are simply worn out.
- Oxygen content exceeded
The water in the pipes is oversaturated with oxygen, so bubbles form when heated. This causes noise and vibration not only from the boiler, but also from heating radiators.
Air has formed in the system
If the boiler is knocking, it is necessary to bleed the air in the pipes. Modern batteries have taps installed. Air is released when the taps are unscrewed.
How to remove air from the battery yourself?
The accumulation of air in batteries after a break in the heating season is not a rare occurrence. This is a common problem not only in private homes, but also in apartment complexes. Its solution is not a complicated process. Heating batteries and radiators are equipped with Mayevsky taps. They are located on the side of the batteries. In appearance, most often they resemble a valve.
To bleed air from the battery, you need to:
- Prepare a cup or bucket for water that will flow from the tap when unscrewed;
- Open the tap and let out the air;
Attention! This must be done carefully, as there is a risk of getting burned by the steam!
- Tighten the valve after water flows from the tap.
.
Claps
A loud bang when the hot water tap is turned on, sometimes accompanied by vibration of the column. This is due to a malfunction of the gas supply system in the working compartment.
An excessive amount of flammable mixture accumulates in it, which does not have time to ignite. This creates excess pressure. As soon as the gas ignites, an explosion occurs, accompanied by a bang.
In this situation, it is better to immediately contact specialists, since gas emissions can lead to destruction of the chimney.
You can try to fix the problem yourself like this:
- Turn off the gas supply and remove the outer part of the dispenser box.
- Clean surfaces from dirt. If soot has accumulated on any parts, clean the injectors.
- Inspect the electrodes. Clean them or replace them with new ones.

- The “Levels” tab will appear in the window that opens.
- In the Realtek settings, under the first line, additional sources will be displayed that need to be reduced to the minimum level.
- Next you need to open the tab called “Improvements”. Opposite the Loudness parameter there should be a checkmark confirming that it is enabled. This option may be called differently in different versions of the operating system, such as “Volume Leveling.”
- After making new settings, you should check the sound.
Driver problem
Software is an important component of equipment operation. In some cases, the problem can be completely corrected by a simple software update. Some operating systems independently notify the user that the driver needs to be updated and perform this procedure automatically.
Otherwise, you can find the program you need on the Internet. They are in the public domain.
Afterwards you need to make the necessary settings.
- The procedure begins by opening the “Control Panel”.
- The next item is “Equipment and Sound”.
- Find the subsection that is responsible for the sound driver settings. In most cases it is called "Realtek HD Manager".
- Open this item and carefully evaluate the menu. When changing parameters, evaluate the result. You can turn some audio filters on or off, and change the volume.
Questions about speaker malfunctions
Column NEVA LUX-5514 after changing the membrane in the water-gas unit, the tap regulating the gas supply to the burner stopped working. How to fix?
The gas outlet channels on the heat exchanger are clogged. Remove it and wash the top with a strong stream of water - everything will work.
In the Neva 3208 column, the igniter burns well, but inside it barely smolders, although the handle is turned to full power. What is the reason?
Membrane problem. It needs to be replaced.
Beretta speaker, I've been using it for 8 years. The igniter lights up only after 30 clicks on the piezo ignition, or it lights up and goes out immediately! What can be done?
A malfunction indicates a blockage or failure of the ignition group. Perhaps cleaning it will help. But most likely it will need replacement.
To eliminate problems in the operation of a gas water heater, you need at least basic knowledge about its structure and repair skills. If your speaker is under warranty, don’t hesitate to contact a specialist. They will eliminate the cause of the malfunction free of charge and repair or replace the necessary parts of the device. You cannot open the column yourself before the warranty period expires.
Responsibility for unauthorized replacement
It should be remembered that replacing a boiler, water heater and other gas appliances in an apartment in a multi-storey building or in the private sector should only be carried out by qualified employees who have official permission to perform work with gas and gas equipment. You can also contact specialists from the state gas service. Self-repair or connection of equipment is not prohibited by law, but it is necessary to understand the full responsibility of such actions.
If you independently interfere with the gas supply system and tap into it without permission from the gas service, you will bear full responsibility in accordance with Federal Law No. 229-FZ adopted in 2021 “On amendments to Article 215.3 of the Criminal Procedure Code of the Russian Federation and Articles 150 and 151 of the Code of Criminal Procedure of the Russian Federation” .
There is a fine for such violations of up to 80 thousand rubles. Also, the violator may be punished by performing correctional labor for up to 360 hours. The offender can also be sent to correctional labor for up to one year.
In addition, they may be sentenced to restriction of freedom or complete deprivation of freedom for 2 years. In the event that after an independent intervention in the gas system, an accident occurs, as a result of which people were injured. Then the violator will be punished with the same fine, correctional labor for up to five years, and even imprisonment for up to 8 years.
If you do not have the opportunity to carry out repairs yourself, then contact a specialist; do not forget that working with gas is very dangerous not only for you, but also for the people around you
To replace gas equipment, you must have a special permit. If an accident occurs and people are injured, the culprit will suffer administrative punishment upon initial prosecution, in accordance with Article 7.19 of the Code of Administrative Offenses of the Russian Federation in the form of a fine.
If a violation is detected again by the same person, the violator will be prosecuted in accordance with the adopted Federal Law No. 229-FZ “On amendments to Article 215.3 of the Criminal Code of the Russian Federation (CC RF) and Articles 150 and 151 of the Criminal Procedure Code of the Russian Federation (CCP RF)".
If the boiler makes noise during operation
If you hear noise while the gas boiler is on, it means there are certain problems. First you need to discover the reasons, and then begin the process of getting rid of the annoying sound:
- Water may make noise in the pipes. This may indicate a malfunction in the heating supply. If action is not taken to correct the situation in time, some heating element may fail.
- Extraneous sounds - noise, clicks in the heating radiator or radiators significantly worsen the quality of living in the apartment. If the heating pump or other system component is noisy, we advise you to first try to localize the cause of the extraneous sounds. To do this you need:
- Trace the periodicity and frequency of occurrence of various sounds.
- Try to trace exactly when the sounds occur - with an increase/decrease in temperature or pressure.
- Make sure that the source of the sounds is the boiler and not other equipment in the boiler room.
Character of noise
Pay attention to the noise, but it could be:
- Uniform monotonous.
- Uneven, with a crash.
Uniform noise can occur even when operating a new, recently installed boiler, but the second one can occur only after some time.
Is the noise in a gas boiler dangerous?
No, not dangerous. There will also be no defects or threats to operation in the heating system. Noise can only create discomfort in living rooms.
How to get rid of noise?
The only option to get rid of noise in a working boiler is to reinstall the system from open to closed. Reworking the system will not affect the ability of it to operate without a pump. In addition, there will be an excellent opportunity to install an auto-recharge system and a weather-sensitive automatic system.
Lime deposits: the cause of noise in the boiler
Often, extraneous sounds do not appear immediately, but after a certain period of operation of the device. Why does the boiler make noise in this case? The thing is that lime deposits cause noise. They form on the walls of the heat exchanger after a certain period of operation.
Why is the gas boiler still clicking? The cause may be lime deposits. They cover the walls of the heat exchanger from the inside, due to which the temperature of the internal walls of the heat exchanger begins to increase sharply, which also affects how long the equipment can last. In this case, we will hear clicks, knocks, and noises.
It is necessary to carry out maintenance of the boiler at regular intervals, regularly clean the device from soot, scale, dust, and dirt. This will significantly increase the service life of the boiler and prevent problems with its operation.

Scale formation
A high salt content in water leads to scale deposits on the walls of the device. When heated, the salts will make themselves known by hissing. Because of this, the device heats up much more slowly. The radiator needs to be cleaned once a year. To do this, you will need a reagent, a special pump through which the reagent is poured into the device and rinses it from the inside.
Scale in the boiler - how to deal with it
In radiators, water does not move as quickly as in pipes, and the sedimentation of suspended matter is many times higher. Regular cleaning of radiators is necessary. You can flush the entire system at once or separately the radiators using a compressor unit. To flush, the radiator is connected to the compressor, and dirt is cleaned from it with water pressure.
Sometimes it is enough to simply flush the system with strong water pressure. Chemical reagents are used in cases where the situation with scale deposits is extremely advanced.
Scale formation deforms the device
Under the influence of chemicals, cracks may form in radiators that were clogged with salts. In order to prevent an emergency, before starting the system, all equipment must be checked for readiness for operation.
Infrared heating panels
Excessive pressure in the heating pump
The pump provides high pressure; it is necessary to adjust its settings. Excessively high pressure in the system can provoke an emergency.
A low amount of water in the system may cause the device to overheat. Try lowering the thermostat. You may need to add water to the device to the required level.
Heating pump
- If the boiler seems to “howl”, the gas valve may be set incorrectly, check the jumpers.
- At high power, the source of extraneous sounds may be the gas meter.
- The valve was worn out and began to rattle. It needs to be replaced. If the problem is not solved and the boiler is still noisy, you can replace the valves with ball valves and install a rubber gasket.
- If the above measures do not help, you may need to replace the cooler.
