Incorrect operation of a gas boiler is a sign of equipment malfunction. This fact should not be ignored. Especially if there is a popping noise when you turn it on. There are several reasons why this phenomenon occurs. It is not always possible to solve the problem yourself. Therefore, it is worth understanding why the gas boiler slams loudly when turned on and how to act in such a situation.
We recommend reading: Why a gas boiler does not work, the main causes of malfunctions.
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.
Other causes of noise
Sometimes the cause of noise in a working geyser is not a breakdown, but loose communication connections or a poorly secured element. Therefore, if extraneous sounds appear, it is worth checking the tightness of the parts and pipeline connections. You can also see if anything has gotten into the device body. Perhaps after the last disassembly they forgot a bolt, electrical tape or other item.
When noise appears in a gas water heater, it is important to determine the cause and solve it as quickly as possible. A hum is the first sign of a problem with the device. If the problem is not corrected in time, it will gradually lead to more serious consequences. As a result, you will have to buy a new gas water heater instead of small repair costs.
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.
The speaker hums and makes noise during operation
The cause of noise when heating water is insufficient draft. Therefore, in noisy equipment, it is the first thing to check. A lit match or lighter is brought to the control holes or a special hatch in the upper part of the column. If the flame deviates towards the device, the draft is sufficient. Otherwise, care should be taken to clean the chimney duct.
Also, noise can be caused by insufficient air flow into the room, for example, if plastic windows are installed in the kitchen. The seals in such windows interfere with the natural ventilation of the room. In this case, to eliminate noise, you should simply control the air flow.
Another reason the column is too noisy is that the pilot burner wick is dirty. And then to eliminate the noise, it is enough to clean the jets. A similar situation is possible if the jets in the main burner are clogged, then after cleaning it, the hum during operation of the column disappears.
In modern speakers that are turned on using electric ignition, the cause of noise during operation may be as follows:
- Discharged batteries. As a result, the gas-air mixture is difficult to ignite. In such a situation, the batteries need to be replaced.
- Damage to the sensor that controls the water supply. Often its malfunction is caused by oxidation of the contact group. Usually this sensor is not removable, so it is replaced.
- A spark plug malfunction prevents an electric spark from being produced. Most often, it shifts after many heating-cooling cycles. By returning the spark plug to its nominal position, you will restore the possibility of spark formation and eliminate extraneous noise.
- Problem with mechanical ignition retarder. Its presence can be determined after dismantling the assembly and shaking it - normally you should hear the noise of the ball moving inside the moderator. If there is no sound, this indicates that the ball is moving. You can return it to its place using a soft wire.
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.
And the neighbors are noisy too
More often than not, it's not just you and your family who suffer this. Therefore, you first need to go around the neighbors along the riser to identify the location of the noise.
Let's find out where the pipes are making noise
Now, as for the nature of the buzz. Heating pipes, like water pipes, can emit single or rhythmic sounds, something like tap dancing, rustling, gurgling, or even generally vibrate and even hum – periodically or constantly. The reasons can be completely different, they are even classified into groups. But now we will not consider absolutely all of them, but will focus only on impact noise effects.
Note: The likelihood of noise in pipes is sharply reduced if you use metal-plastic or plastic pipes instead of metal and copper. This is explained by the high sensitivity of steel pipes to low-frequency vibrations and high rigidity. Although their material is much stronger. It is recommended to use ball valves rather than screw valves as shut-off valves, which are controlled by turning the handle. These are heavy cast copper products, not Chinese-made products made from light alloy material.
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.
Diagnostic method
If you decide to carry out repair work yourself, the owner must strictly follow the instructions. First of all, experts advise checking the intensity of the chimney draft. The main part of the geysers is equipped with a casing, which has holes provided just for this procedure. If the column manufacturer has not made such holes, the draft can be checked right next to the slot located at the smoke hood. In addition, the draft is perfectly felt at the chimney cleaning hatch.
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.

If the popping noise continues after cleaning the gas supply parts, you should not use the dispenser without inspection by gas service specialists!
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.
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)".
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.
The principle of operation of the stabilizer
Since only relays are capable of clicking in the stabilizer, it means that it is made according to a relay circuit. Each relay stabilizer has an autotransformer in its structure that increases or decreases the voltage based on the ratio of the turns of the windings. When the voltage value approaches the upper limit of the range, the device circuit switches to the autotransformer winding with a lower voltage value, and, as a result, the output voltage becomes lower. In the same way, this works in the opposite direction: when the voltage in the network deviates towards the lower threshold, the stabilizing device switches to the step-up winding of the autotransformer.
The process of switching the transformer windings is supervised by a special device - the stabilizer controller, and the switching is made through a set of power relays. It is these relays that, at the moment of connection, produce the very clicks that the user hears.
A standard stabilizer can contain from four to seven power relays. And the more voltage surges in the power supply network, the more often switching occurs and clicks are heard. Also, at these moments, the light may blink and highly sensitive equipment may turn off.
The boiler (titanium, water heater) makes a sound. Howls, squeaks, crackles, whistles, buzzes
Over time, any boiler (water heater) will sooner or later begin to make extraneous unpleasant sounds.
On the Internet, people talk about many reasons that are responsible for the generation of different sounds, but I could not see the correct actions to eliminate these problems anywhere.
I can offer you my version of searching and eliminating these problems associated with the sound of the boiler.
The main reasons for the appearance of a squeak, buzz or whistle in the boiler can be identified in three ways:
A large layer of scale or limestone deposits appeared on the heating elements
The bypass valve and the plumbing associated with it are acting up
Very poor water quality in your home
Now about everything in more detail...
Scale on the heating element of the boiler (heating element) may be the least likely problem in the appearance of whistles.
But, if the scale does not exceed a thickness of 1 cm on the element, otherwise, this will also be a source of whistles, crackles and other sounds in the boiler.
In some settlements and cities, local water treatment services do not properly degas water, probably on purpose, since this increases water consumption according to meters, with smaller volumes of water consumption.
In human terms: as a rule, there is always a certain percentage of air in water; in some certain areas of our country this percentage is more or less than the average value. According to utility standards, services must remove excess air in water to a certain standard value. This same air can subsequently create the effect of a characteristic sound when the water begins to heat up. A friend of mine in the city has this exact reason why the boiler beeps. I live in Vladivostok, it seems that we don’t have such an effect from water.
An even more common cause of boiler sounds is a problem bypass valve.
When purchasing a boiler with the tank itself, there is an accompanying combined device, which is designed to relieve excess (excessive) pressure in the tank and a check valve designed to prevent the outflow of water in the opposite direction. Over time, if the pressure in the boiler tank is constantly high, with frequent discharge of excess water, this valve begins to undermine. And it is recommended to replace it. Fortunately, it’s not difficult, any man with his hands can do it.
This valve is also responsible for equalizing pressure not only in the water heater, but also in pipes located below and above itself. For example, neighbors or you open a cold water tap, the pressure in the water supply drops and a certain amount of water passes through this valve with a sound from the water heater into the water supply.
In rare cases, the relief valve may make sounds when there is increased pressure in the cold water riser. The way to eliminate the problem is to install a pressure reducer on the apartment's water supply system.
Possible breakdowns of Baxi boilers
Repair work on baxi boilers should be done with your own hands only if there are visible and easily removable causes of the breakdown. If you have no experience in handling the units or do not have special tools, it is better to entrust boiler repairs to a competent technician.
Possible breakdowns:
- — the boiler burner does not turn on or goes out;
- — ignition becomes impossible;
- — popping sounds are heard in the combustion chamber;
- — the boiler overheats;
- — the maximum heating temperature of the coolant becomes insufficient;
- — the boiler operation becomes noisy;
- — one of the sensors or elements of the system fails.
Causes of failure of baxi boilers:
- — moisture has entered the boiler;
- — water (coolant) of low quality;
- — there has been a drop or decrease in gas pressure in the gas pipeline;
- — there was a power supply voltage drop;
- — the heating system was installed incorrectly.
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.
How to get rid of sound?
You can get rid of extraneous hum in your speakers yourself. Let's consider what to do for this.
Computer settings
Incorrect settings used when configuring Windows OS (a common operating system installed on most computers) often cause humming noise in the speakers.
To fix problems, you need to perform a number of steps.
- Open Control Panel. You can find the required item in the Start menu.
- Click on the "Hardware and Sound" section. There will be a subsection called "Sounds".
- Select the audio playback device marked with a green checkmark.
- Right-click on it and then click on the “Properties” line.
- 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.
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.

Recommendations
To ensure that the equipment works for a long time and properly, listen to the following operating recommendations.
- Surround, clear and loud sound is only possible when using high quality equipment. You shouldn't demand much from cheap acoustics.
- Transport speakers carefully by packing equipment using boxes, foam, bubble wrap, and other options.
- Update your driver regularly.
- Acoustic equipment quickly becomes unusable due to high humidity.
- Make sure that the cables are not under too much tension.
To learn about the reasons why speakers hum, see the following video.
The water heater is shocking
What can I say, because the problem when a water heater shocks is quite common. The reasons why the water in the boiler may cause electric shock or the body of the device itself may be as follows:
- There is no grounding in the house or apartment;
- The heating element or water heater power cable is damaged.
To solve this problem, it is enough to check the heating element for damage due to corrosion. If the heating element is still completely new, then you should take a closer look; perhaps somewhere inside the boiler there is a damaged power cable that touches the metal body of the device.
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.
