The water heater solenoid valve is the core component of the gas water heater. It is the main role of controlling the ignition of the gas water heater. It is an important guarantee for whether the gas water heater can be used normally.
The water heater solenoid valve cannot be opened
If it is a liquefied gas water heater, it may be the failure of the pressure decompression valve on the liquefied gas cylinder, causing the solenoid valve of the water heater to be too large in air intake pressure and cannot be opened, so it is not ignited. It is recommended that you change the battery on the machine (If the machine is used, the pressure of the pressure reduction valve on the cylinder is smaller and then turned on. If it does not work, you can only change the new decompression valve (be sure to buy a regular manufacturers decompression valve).
Working principle
First of all, when the cold water enters the water heater, it will pass through the water and gas linkage valve body. Under a certain pressure of water flow, the water -gas linkage valve and micro -switch can be pushed to connect the power supply.At this time, open the gas solenoid valve and lit the burner of the gas water heater.After the burner is ignited, the flame detection element will detect the flame signal, and then transfer it to the pulse controller. The pulse controller will open the solenoid valve by maintaining the current and maintain the normal combustion of the burner.If the burner is not successfully ignited, the pulse controller cannot receive the flame signal, so that the current can be guaranteed to ensure the normal turn on the solenoid valve by maintaining the current.
Water heater solenoid valve does not suck
Reasons: 1. The battery is not electrostatic, and you need to change the new.2. The solenoid valve is broken, the internal line is damaged, and it cannot be sucked.3. There is a problem with the control circuit of the igniter. Although it can be ignited, it cannot control the normal operation of the solenoid valve.

How to repair the solenoid valve of the water heater
The water out of the water is normal, and the electromagnetic valve has no response. If the water outlet is normal when the water outlet is performed, but there is no fire sound, then we can check whether the battery is poorly exposed or there is no electricity. If the battery problem, you can change the battery to try.If the battery is replaced, it is still not possible to work normally, then it may be that the total switch of the water control power supply is poor.We need to open the hot water and check the total switch of the water control power supply installed in the lower part of the water heater. You can use some tools to dial the small iron sheet.Just change it.The solenoid valve failure is to be burned normally after watering the water heater, and the fire indicator is on, but the fire continues, and then the ignition is stopped in about ten seconds, and the combustion is stopped at the same time.Then this situation is that there is a problem with the circuit of the fireplace. Generally, the probe in the fireplay is poorly exposed to the wires, and then in order to prevent the gas from entering the burner and cause harm, it cannot work normally.Then we need to replace the solenoid valve and use it after the replacement.
