The gas water heater can t catch fire, and the temperature can t be adjusted when it s on

The reasons and solutions for the gas water heater not to catch fire and the temperature cannot be adjusted are as follows:

Power issues, whether the battery is too old. Phenomenon: Check whether the AC power plug indicator is on, if not, it means that it is a power supply problem.

Solenoid valve failure. Phenomenon: If only the ignition sound is heard during ignition, and there is no magnetic suction sound of the solenoid valve "clicking", it may be that the solenoid valve is damaged or aging. If.

The solenoid valve is aging, and it can be engaged at the beginning of the ignition, and it can catch fire, but then it goes out again. It may also be that the gas pressure is too high or too low, and the output pressure of the cylinder pressure reducing valve will be too high or too high in the water heater using cylinder gas.

low, resulting in the water heater can not be ignited. It is also possible that the solenoid valve is dirty. If the solenoid valve cannot be overgased, the gas will not come out, so that it will not ignite. Before confirming the solenoid valve failure, it is necessary to check the ignition control circuit.

Whether it is normal, if there is a fault, it cannot control the solenoid valve to suck in.

Solution: Check the elimination method one by one to determine the specific cause. If the solenoid valve is aged, replace the solenoid valve. If there is a problem with the gas pressure, replace the gas cylinder with a new one. If there is any swag on the gas valve, clean it up. If the ignition control circuit, the circuit problem is repaired.

Faulty electric igniter. Phenomenon: No ignition sound and no electric sparks.

Solution: Check whether one of the pulse igniters and controller is faulty, and replace or repair if there is a fault.

Problems with ignition porcelain needles or induction porcelain needles. Phenomenon: No ignition sound or electric sparks.

Solution: Check whether the ignition needle is out of position or aging, and replace or place the ignition needle correctly. If the induction porcelain needle is aging, the induction porcelain needle can be polished and placed as long as the flame can fully burn the porcelain needle.

Water pressure problems. Phenomenon: There is a sound of fire and sparks, which are quickly extinguished when they ignite.

Solution: Turn on the faucet to check if the water pressure is too low, if the water pressure is too low, only stagger the peak water consumption period.

The water-gas linkage device is malfunctioning. Phenomenon: No ignition sound or electric sparks.

Solution: Check that the eardrum in the water-gas linkage valve is aging or damaged, and the micro switch cannot be pushed, then replace the water-gas linkage valve or repair.

The air supply is not turned on or the air intake filter is blocked. Phenomenon: There is no electric spark when there is a slight fire.

Solution: Turn on the air source and clean the air intake filter.

The gas type does not match. Phenomenon: There is no electric spark when there is a slight fire.

Solution: If the liquefied gas water heater is connected to natural gas, it is necessary to change the liquefied gas water heater to a natural gas water heater before it can be connected and used.

The valve seals are corroded by the gas and swelled. Phenomenon: There is no electric spark when there is a slight fire.

Solution: Replace the parts.

The smoke exhaust pipe cannot be vented. Phenomenon: There is a slight fire and electric spark, but it goes out quickly.

Solution: If the smoke pipe is blocked, clean the smoke pipe. If the pipe is too long, reinstall it correctly.

If you haven't changed the battery for half a year (there is usually a plastic cover at the bottom), replace the battery. Upstairs doesn't know how to pretend to understand, and the landlord's condition judges that the water pressure is high enough or not. It is difficult to fight normally in autumn and winter, and each time you start a fire, you can first adjust the fire (water temperature) to ensure that it is generally played at one time, and wait for a minute for the water to heat and then adjust to the usual water temperature!

Summary. The solution of the gas water heater is not hot when the fire water is hot: 1. The fire power is adjusted to the maximum, some buttons are plastic, which is easy to break, so it does not work when rotating, and it is best to remove the metal rod with needle-nose pliers to twist the fire adjustment.

2. Some water heaters have winter and summer settings, which must be adjusted to the winter position, and the same ensures the quality of the button, and it is best to remove it and adjust it with pliers. 3. The gas pipeline and control valve are completely opened. 4. Detect whether the gas exhaust port is blocked, which is generally not easy to appear, and the method is to open the lid to observe whether the gas discharge is uniform, and whether there is a large and a small flame when burning.

There is no sudden gas sound. 5. The water heater has a long life, the scale in the water tank pipe is too thick, and the heat utilization rate is too low, so it is recommended to replace it with a new one.

3. The gas pipeline and control valve are completely opened. 4. Detect whether the gas exhaust port is blocked, which is generally not easy to appear in the fine state imitation, and the method is to open the lid to observe whether the gas exhaust gas is uniform, and whether there is a large and a small flame when burning. There is no sudden gas sound.

5. The water heater has a long life, the scale in the water tank pipe is too thick, and the heat utilization rate is too low, so it is recommended to replace it with a new one.

The temperature of the heat exchange surface of the water heater is very high, and when the water flows over, there will be scale, and after a long time, there will be a lot of scale attached to the inner surface of the heat exchanger, which will accumulate over time, resulting in a decrease in heat exchange efficiency, a decrease in the amount of hot water output (the phenomenon of small water pressure), and a longer time for hot water output. It is recommended to clean and descale first, buy a set of fast water heater online without removing the scaler, use it to inject descaling agent into the water heater to clean the inside of the water heater can be solved, the operation is simple and convenient, use it to clean it regularly, when you can avoid the recurrence of this problem.

Hello dear! It could be that the heating pipe of the water heater is damaged, resulting in the inability to heat the water. In addition, the temperature regulator may not work and the water temperature cannot be adjusted.

Methods to solve auspicious chops: 1Check that the heating pipe of the water heater is working properly and replace it if there is a problem.

2.Check that the thermostat is working properly and replace it if there is a problem. 3.

If there is no problem in the above two situations, you can check whether the power supply line of the water heater is normal, and if there is a problem, it needs to be fixed.

Hello dear! If the water heater is lit but not hot, and the temperature cannot be adjusted, there may be the following reasons:1

The hot water outlet of the water heater is blocked, causing the hot water to not flow out. You can check the hot water outlet of the water heater for foreign objects or blockages such as limescale, and you need to clean it. 2.

There is a problem with the hot water line of the water heater, which prevents the hot water from flowing. You can check whether the hot water pipeline of the water heater is leaking or whether the pipe connection is loose and needs to be repaired or replaced. 3.

The hot water thermostat of the water heater malfunctioned, causing the temperature to be unregulated. You can check whether the thermostat of the water heater is damaged or out of order and needs to be replaced. 4.

The hot water heating element of the water heater is faulty, causing the hot water to fail to heat. You can check whether the heating element of the water heater is damaged or out of order, and the search needs to be replaced. If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for inspection and repair.

At the same time, to ensure safety, do not disassemble or repair the water heater by yourself.

Summary. 1. Insufficient battery power When the gas stove battery is insufficient, the ignition sound will be soft and weak, and the frequency of the discharge sound is obviously slower than usual. 2. If the gas is not connected, if the sound is crisp and powerful when ignition, but it is not ignited, then it should be considered whether the gas pipeline is unobstructed, and it is recommended to check whether the gas pipeline is flattened or bent once, and re-ignite it after straightening it.

3. The fire hole or nozzle is blocked, and the nozzle of the stove head or the fire hole of the fire cover is blocked, which will hinder the gas flow out and cause the fire to not ignite. This is done by removing the fire distribution cap, then using a thin iron wire or toothpick to unclog the lower nozzle hole, clean the fire distribution cover and then try to re-ignite. Fourth, the flame-out protection device, some of the modern new gas stoves have a temperature measurement safety device, which requires the nozzle to reach a certain temperature and put on the pot before it can be stably burned.

5. Blockage of the pressure regulator If the air inlet and nozzle of the pressure regulator are blocked by rust, it will also cause the gas stove to fail to ignite, so you should replace it with a new pressure regulator and try to fire it again. 6. Pipeline blockage, pipeline blockage causes gas to not reach the fire hole, which may also cause the gas stove to fail to ignite. Generally speaking, if you can smell the gas but do not catch the fire, it is likely that the gas is blocked, and you should consider unclogging or replacing the pipes.

7. Insufficient gasMost people will know that there is not enough gas, but some people are too busy or sloppy at work, and forget to check whether the gas is sufficient.

1. There is a problem with the power supply. Please check whether the AC power plug indicator is on, if it is on, rule out the problem of the power supply part. 2. Electric igniter failure.

If the water heater still can't ignite, judge that one of the pulse igniters and the controller is faulty, and the water heater can't be ignited. The controller should be replaced, or the relevant personnel should be called for repairs. Related knowledge popularization:

1. If there is a problem with the ignition porcelain needle or induction porcelain needle. The gas water heater cannot ignite because it is very difficult to ignite when the ignition pin is offset or aging, so it can be replaced or placed correctly. If the induction is aging, the induction can be polished and placed, so that the flame can fully burn the induction needle regardless of whether it is a large fire or a small fire.

2. Check whether the solenoid valve of the water heater is faulty. If the water heater can't catch fire, you can only hear the sound of fire, but if there is no magnetic sound of the solenoid valve, it may be that the solenoid valve has an aging phenomenon, and the solenoid valve should be replaced or repaired in time, and it is best to find a professional person to replace it. Check that there are problems with the control circuit from time to time, and if there is a problem with the internal circuitry, it will also affect the operation of the ignition.

If there is a fault, the suction of the solenoid valve cannot be controlled.

Summary. 1. Power supply problem The solution to the gas water heater that does not catch fire: check whether the AC power plug indicator is on, and first eliminate the problem of the power supply part.

Second, the solenoid valve failure The solution to the water heater can not catch fire: if only the ignition sound is heard when ignition, and there is no solenoid valve "click" magnetic suction sound, it may be that the solenoid valve is damaged or aging, and the solenoid valve is aging, which will not be controlled. It may also be that the gas pressure is too high or too low, and the water heater using cylinder gas will produce a cylinder Pressure Reducing Valve The output pressure is too high or too low, and the water heater cannot be ignited; It is more likely that the solenoid valve has dirt. The solenoid valve can not be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) can not come out, and it cannot come out, resulting in ignition and fire.

Before confirming the quality of the solenoid valve, it should be confirmed whether the ignition control circuit is normal, and if there is a fault, the solenoid valve can not be controlled.
