Why does the water heater explode when it is turned on?

1. The ignition difficulty caused by the unobstructed airflow and insufficient oxygen supply can be tried to improve the ventilation conditions.

2. Under the premise of sufficient electric energy, the ignition circuit ignition lags behind or needs to be ignited repeatedly, which is the problem of the high-voltage generator of the ignition device, which needs to be overhauled to solve.

The so-called "loud noise" is actually due to a malfunction in the electronic ignition system of the water heater, resulting in a "deflagration" phenomenon during ignition.

When there is a problem with the ignition system of the controller of the water heater, the frequency of the electric shock is low and the energy is small, and the gas cannot be ignited normally; When the gas accumulates to a certain concentration in the cavity, it encounters ignition and deflagration, which is called "detonation".

It is also possible that there is a problem with the ignition procedure of the water heater that causes the gas solenoid valve to be opened first and then the gas solenoid valve is fired.

The problem with the water heater is caused by the ignition time lagging behind the gas.

Possible causes:

However, the air pressure does not meet the requirements specified in the manual or the pressure is unstable;

There is a problem with the pressure regulator of petroleum liquefied gas, so that the pressure or inlet volume of natural gas does not meet the requirements; The nozzle of the main burner of the water heater does not meet the requirements (referring to the pipeline gas);

The center line of the flamethrower and the center line of the sprinkler are not on the same line, that is, there is a deviation between the two.

It is the pressure of the water that pushes the ignition switch, and then the gas is lit, which may be related to the pressure of the water.

It is normal that the sound is not loud, this is because, when the hot water valve is opened, the solenoid valve on the gas pipeline is also opened at the same time, the gas enters the combustion chamber is distributed, the igniter is at one end, when the gas spreads to the igniter, the combustion chamber is already full of gas, so the ignited gas is not a little, but a small group, I heard Peng's voice, it is a normal phenomenon, don't worry, if the sound is too loud, it is abnormal, it may be that the ignition delay time is too long, and you should find after-sales service to adjust it.

A water heater is a device that turns the temperature of cold water into hot water in a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc.

Normal. Before combustion, when the gas concentration has not reached a certain concentration, because the air is mixed, it will happen** (that is, the sound of jumping you hear). However, this does not happen with any proportion of gas-air mixtures**, only when the concentration of combustible gases in gas-air mixtures is within a certain range.

When the gas concentration continues to increase, it is normal combustion.

Don't worry, it's okay.

Everyone has a water heater at home, and it is very convenient for the water heater to boil water, and it can be controlled at a constant temperature and boiled water automatically, so that hot water can be used anytime and anywhere. However, I believe you have also had such an experience, the water heater at home occasionally makes some noise, even if it is useless, it is still ringing. So what's going on in this situation?

1) Electric water heater.

When heating, it is normal for there to be a slight noise in the tank.

2) Because there is limescale on the surface of the heating pipe, abnormal sound will be generated when heating the water heater. The heating tube can be removed to clean the limescale and cleaned at least once a year in the future, or replaced with a new one.

3) Because there is air in the inner tank, pressure is generated when the water is heated, and a sound is emitted. Just release some hot water and expel the air, and it will return to normal.

4) The water heater pipe is not properly fixed, and the water pressure of the tap water fluctuates greatly and produces noise. The piping needs to be re-secured and pressure reducing valves added.

to stabilize the water pressure.

5) The mixing valve is faulty or slightly blocked, and the pressure is too high without making noise. Simply replace or adjust the mixing valve.

There is still a possibility of **.

If the pressure of the inner tank is too high, when the inner tank cannot withstand it, the water heater will **. This usually only happens if both the pressure relief valve and the thermostat are damaged. As the temperature control is disrupted, the water heater will continue to heat up and the pressure in the internal tank will continue to rise.

When the pressure relief valve is in good condition, it will be discharged from the pressure relief valve port, but once it ruptures, it will not be able to drain the pressure.

In addition, a large amount of gas is released from the machine, but it cannot be ignited directly, and it will ** once it encounters an open flame. Therefore, if there is a sound when the water heater is used, it must be stopped and repaired in time, especially for unqualified water heater products, it must be recognized for the 3C national mandatory safety certification.

Gas water heaters.

The main reason for the humming sound is the burner, which is the main accessory of the water heater. When ignited, the burner burns unsteadily, causing the flame to stall, and making noise.

As we all know, oxygen is required for the combustion of materials, so gas water heaters heat cold water in a very short time, which requires a lot of heat, which means that air needs to be constantly replenished.

Since air is constantly being drawn into the combustion chamber and the rotation of the fan causes the enclosure to resonate, resulting in mechanical noise, a gas water heater emits a constant humming sound when it is running. The principle is similar to that of an electric fan in the home.

The ** sound from a water heater is usually caused by a number of reasons. Here are a few possible reasons:

1.The sediment and dirt that accumulate at the bottom of the tank will form bubbles, which will make a sound similar to "**" when the bubbles expand rapidly under high temperature and pressure.

2.The electric heating element inside the water heater is aging, damaged, or overloaded, causing the water heater to not work properly, resulting in abnormal sounds.

3.Problems such as leaking water heater pipes or loose joints can cause poor water flow or abnormal water pressure, which can cause the water heater to make noise.

4.The water heater is not installed in a standard or used improperly, such as excessive amplification of firepower, etc. The internal pressure or overtemperature of the water heater is overheated, resulting in abnormal sounds.

1.Turn on the water heater and remove sediment and dirt from the bottom of the tank to ensure that the water heater is working properly;

2.Check whether the electric heating element of the water heater is aged, damaged or overloaded, and replace it in time;

3.Check whether the water heater pipeline is leaking or whether the joints are loose, and deal with the problem;

4.Confirm whether the water heater is installed correctly and use the specifications to avoid abnormalities caused by improper operations such as excessive amplification of firepower.

There may be a variety of reasons why a water heater may have a ** sound, and the following are some of the situations in which this sound may appear:

1.Water temperature is too high or water pressure is too high: If the water heater makes a sound like boiling or boiling, it may be because the water temperature is too high or the water pressure is too high, causing the water to boil in the water heater.

In this case, it is recommended to adjust the water temperature or reduce the water pressure a bit to prevent the water from over-pressurizing during the internal boiling process of the water heater and causing safety accidents.

2.Stagnant or clogged water: If your water heater makes a rotten sound like bubbling or pumping, it may be due to sediment at the bottom of the water heater or trash in the pipes causing the water to accumulate or become clogged. In this case, limescale can be removed or water pipes can be unblocked.

3.Pipe leakage: If the water heater makes a sound like a gas leak, it may be caused by a leaking water heater pipe. In this case, the gas** should be turned off immediately and repaired by a professional. Judgment.

In conclusion, if your water heater is experiencing unusual sounds, then it is recommended that you stop using it immediately and consider seeking professional help or inspection to ensure your safety and that of others.

The machine you are talking about has a faulty ignition.

The main reason was a problem with the controller ignition system. The frequency of the electric shock liquid mold is too slow, and the electric shock energy is too small to meet the requirements of normal ignition of the gas, which quietly causes the gas to reach a certain high concentration density in the cavity and deflagrates after encountering an open flame. If the machine is using a battery, try to replace it with a new battery, and if it doesn't work, ask a professional to check and repair it!!

Under normal circumstances, the machine ignites the solenoid valve first, and then opens the ventilation, and burns when it encounters ignition. If the ignition program of the machine fails, it is easy to deflagrate!

When the machine starts the ignition at one time and does not ignite, the solenoid valve is opened for a few seconds to ventilate, and the ventilation is closed after the ignition stops. Therefore, it is best to wait a minute or two before starting the ignition to avoid deflagration.

The water heater has a ** sound that may be caused by the following reasons:

1.Overheating: If the temperature of the water heater exceeds its tolerance range, the water will turn into vapor, which in turn will cause a ** sound. This usually happens when the water heater is not cleaned regularly.

2.Overpressure: The pressure control of the hot water heater is out of shape, resulting in too high pressure inside the water heater, and then **sound**.

3.Pipeline blockage: The pipeline blockage of the water heater will produce high pressure, which in turn will lead to ** sound.

4.Insufficient water filling: If the water heater does not have enough water to cool down, it will overheat and produce a ** sound.

Therefore, when the water heater has a ** sound, you should turn off the water heater immediately and contact a professional maintenance personnel for inspection and repair. This avoids potential security risks.

Summary. In general, the explosion of an electric water heater is caused by overload or underload. The causes of overload are generally as follows:

1.The overload switch has insufficient capacity to withstand the load. 2.

When the electric water heater is working, there is a leakage, open circuit or short circuit, which makes the overload switch fuse and make a loud sound. 3.The aging of the switches and components in the electric water heater leads to excessive switching current, resulting in overload and fuse.

4.The surface of the electric water heater is eroded by the high temperature of the outside world, forming a high-pressure phenomenon, which will also make the electric water heater fuse and make a sound. There are several common reasons for underload:

1.There is an open circuit or short circuit inside the electric water heater, which causes the overload switch to not work normally, and the underload phenomenon will also make a sound. 2.

The capacity of the electric water heater is insufficient, can not meet the needs of the work, and the phenomenon of underload will also make a first-class sound. 3.The electric water heater burns out, causing the circuit to be interrupted, and it will also make a ** sound.

Whether it is overload or underload, it is necessary to carry out maintenance in time to avoid unnecessary losses.

I'm still a little confused, can you be more detailed?

In general, the explosion of an electric water heater is caused by overload or underload. The reasons for overload are generally as follows:1

The overload switch has insufficient capacity to withstand the load. 2.When the electric water heater is working, there is a leakage, open circuit or short circuit, which makes the overload switch fuse and make a loud sound.

3.The aging of the switches and components in the electric water heater leads to excessive switching current, resulting in overload and fuse. 4.

The surface of the electric water heater is eroded by the high temperature of the outside world, forming a high-pressure phenomenon, which will also make the electric water heater fuse and make a sound. The general reasons for underload are as follows:1

There is an open circuit or short circuit inside the electric water heater, which causes the overload switch to not work normally, and the underload phenomenon will also make a sound. 2.The capacity of the electric water heater is insufficient, which cannot meet the needs of the work deficit, and the underload phenomenon will also make a loud sound.

3.The electric water heater burns out, causing the circuit to be interrupted, and it will also make a ** sound. Whether it is overload or underload, it is necessary to carry out maintenance in time to avoid losses that do not have to be caused by Piquet.

1.If it may ring, it is the sound of the heating rod heating the water, and the water heater is originally soundproofed! It is recommended to repair, it should be the aging or failure of the water heater, and the kettle is the same as the sound of boiling water, the electric water heater makes a bang during the boiling process, and then feels that the water pressure is small.

2.It may not be related to the water heater, and the storage electric water heater will not be short of water because of the water outage, you can check whether the plug position is burned, that is, the hot electric water heater will also have protective water storage after the water is stopped, and the electric water heater has overheating protection with a bang, and the general empty water will not run when the water heater switch is opened, and the water heater often rings inside.

There are two types of ringing in an electric water heater:

1. The heating pipe of the electric water heater has been covered with scale, when the power is on, the water molecules hit the heating pipe, there will be a sound, which will cause the heating pipe to rupture in the long run, and the hidden danger of electrification in the water appears.

2. If the water pressure is too large, the water tank will be impacted and the sound will be formed, so it is recommended to adjust the water valve slightly to reduce the pressure impact, which is also a way to protect the water tank.

If you can't judge, it is recommended to ask professional maintenance personnel to overhaul it in time.

Hello, I am glad to serve you and give you the following answers: The explosion of the electric water heater may be caused by the failure of the circuit board inside the electric water heater, or due to the open circuit of the hole base power cord of the electric water heater. Workaround:

1.First of all, check the power cord of the electric water heater to see if there is an open circuit, if so, you can try to replace the power cord, or check whether the connector of the power cord is loose, if it is loose, you can try to reconnect it. 2.

If there is no problem with the power cord, you can try to check the circuit board inside the electric water heater to see if there is any damage, if so, you can try to replace the circuit board to answer early, or check whether the connector of the circuit board is loose, if it is loose, you can try to reconnect it. 3.If the above two methods do not solve the problem, you can try to disassemble the electric water heater, check the other parts inside the electric water heater to see if there is any damage, if so, you can try to replace the parts, or check whether the joints of the parts are loose, if they are loose, you can try to reconnect them.

Personal Tips:1When using an electric water heater, you should pay attention to check whether the connectors of the power cord and circuit board are loose to avoid similar problems.

2.If you find that the electric water heater is faulty, you should try to inspect and repair it in time to avoid greater losses.
