Wanhe water heater can t catch fire, Wanhe water heater can t catch fire, what should I do?

1.Battery problem: If you use a battery, you should first see if the battery is too old, and the water heater will not catch fire if the voltage is not enough.

2.Solenoid valve fault: if only the ignition sound is heard at the time of ignition, and there is no solenoid valve "click" magnetic absorption sound, it may be that the solenoid valve is damaged or aging, and the solenoid valve is aging, which will be uncontrollable. Before confirming the quality of the solenoid valve, it is necessary to confirm whether the ignition control circuit can be normal, if there is a problem, the solenoid valve can not be controlled.

3.Ignition fault: If one of the pulse igniters and controller fails, the water heater will not start.

4.Ignition needle or induction needle problem: the ignition needle deviation can be changed or the ignition needle can be placed correctly; If the aging problem of the induction is solved, just polish the induction and put it away.

5.Water pressure problem: The filter screen at the water inlet is infarcted and the water cannot flow normally, so it can be liquidated and cleaned.

6.Water-air linkage installation fault: the tympanic membrane in the water-air linkage valve is aging or damaged, and the micro switch cannot be promoted; The micro switch is broken.

7.The smoke pipe does not vent properly. There is an infarction in the smoke pipe, and the smoke pipe is too long and not properly installed. Please refer to the instructions for double-layer smoke pipe installation of balanced water heaters.

The water heater is not ignited, you can first check whether the water, electricity and gas at home are normal, there are many reasons for not ignition, the water pressure is too low may also cause the water heater to not ignite, pulse igniter failure or poor internal wiring contact may occur without ignition, it is recommended to find the manufacturer after-sales door-to-door inspection.

Wanhe water heater can't catch fire, what should I do?

Wanhe water heater can't catch fire, what should I do? Hello dear, 1. Power supply problem solution: check whether the AC power plug indicator is on, and first eliminate the problem of the power supply part.

2. Solenoid valve fault solution: If only the ignition sound is heard when ignition, there is no solenoid valve "click" magnetic sound, it may be that the solenoid valve is damaged or aging, and the solenoid valve is aging, which will be uncontrollable. 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 low in the water heater using cylinder gas. It is more likely that the solenoid valve has dirt. The solenoid valve cannot be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, so that the ignition cannot be ignited.

1. Solenoid valve failure. Phenomenon: If the liquefied water heater can only hear the ignition sound when it is ignited, and there is no magnetic sound of the solenoid valve "clicking", it may be that the solenoid valve is damaged or aging.

If the solenoid valve is aging, it can be sucked at the beginning of the ignition, and the fire will be ignited, but then the ignition will be extinguished. The solenoid valve cannot be overgased, and the gas cannot come out after the gas, resulting in no ignition. 2. If the ignition fails, if one of the firearms and controllers is faulty, the water heater cannot be ignited normally.

Suggested Treatment:

1. Check the elimination method to determine the specific cause. If the solenoid valve of the liquefied water heater is aging, 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 stolen goods on the gas valve, clean it up. If it is an ignition control circuit, the circuit of maintenance is a problem.

2. Replace the igniter of the liquefied water heater. Before confirming the failure of the solenoid valve, it is necessary to confirm whether the control circuit of the ignition is normal, and if there is a problem, the suction of the solenoid valve cannot be controlled.

3. It may also be caused by the gas pressure being too high or too low, and the output pressure of the pressure reducing valve will be too high or too low when using a gas water heater, so that the water heater can not ignite, and there may be dirty messes for the solenoid valve, which can be cleaned up directly.

1. Battery problem: If you use a battery, you should first see if the battery is too old, and if the voltage is not enough, it will also cause the Wanhe gas water heater to not catch fire.

2. Solenoid valve failure: If only the ignition sound is heard during ignition, and there is no solenoid valve "click" magnetic suction sound, it may be:

a.The solenoid valve is damaged or aged, the solenoid valve is aging, it will be uncontrolled, and it can be sucked at the beginning of the ignition, and it can catch fire, but then it closes and turns off;

b.If the gas pressure is too high or too low, the output pressure of the cylinder pressure reducing valve will be too high or too low for the water heater using cylinder gas, which will also cause the Wanhe gas water heater to fail to ignite;

c.The solenoid valve is dirty: the solenoid valve cannot be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, and cannot come out, so that the ignition cannot catch fire.

Before confirming the quality of the solenoid valve, it is necessary to confirm whether the ignition control circuit is normal, if there is a fault, the solenoid valve cannot be controlled.

3. Ignition failure: One of the pulse igniters and controllers is faulty, and the water heater cannot be ignited normally.

Fault phenomenon: extinguished after a while of ignition.

Cause of failure: Flame-out protection induction pin failure.

The gas stove will be extinguished after a whileFault analysis:

1. Extinguishing the celery fire protection induction needle is malfunctioning. The sensor needle is skewed or the contact is bad. This situation needs to be solved by a maintenance worker.

2. Due to the usual simmering soup overflowing pot, the soup adheres to the flame-out protection needle, resulting in sluggish induction.

Solution: At this time, the flame-out protection device should be cleaned.

3. The fire cover is not properly placed. The fire cover (ring-shaped, surrounded by a black copper object with fire holes) is not placed in place (except for the same size hole around the fire cover, there are two small holes next to each other, these two small holes should be facing the ignition needle), if the fire cover is not properly covered, the gas conduction is slow, and the ignition is slow.

The solution is to reinstall the fire cover.

4. The solenoid valve was not opened, and the gas source did not flow to the fire hole.

Solution: Adjust the height of the thermocouple to let the flame burn it, let it generate voltage due to the temperature difference to open the solenoid valve, and let the air source flow through the fire hole.

5. Check whether the thermocouple and the solenoid valve have formed a circuit loop, if there is no loop, the solenoid valve cannot be opened.

Solution: You can open it with a screwdriver, but if you don't have basic knowledge of the circuit, it is recommended to find an after-sales service.

Check the wind pressure switch, there is usually a problem here.

1. The reason why Wanhe water heater can't catch fire - solenoid valve problem.

There is a problem with the solenoid valve of the water heater, which is a very common fault, if only the sound of the ignition is heard, and there is no sound of the solenoid valve, it is usually divided into two types.

1. The solenoid valve is damaged and aging. For example, when the fire is fired, it can be hit, but it will be turned off immediately, which is the phenomenon of aging of the solenoid valve, and if the solenoid valve is damaged, it can not be ignited at all, so the solenoid valve can only be replaced.

2. The solenoid valve is dirty. In this way, the solenoid valve blocks the gas and cannot pass the gas, and the gas cannot come out, of course, it cannot catch fire.

Second, the reason why Wanhe water heater can't catch fire - power supply problem.

If the water heater uses a battery, if the battery is too old, the voltage is not enough, or the positive and negative poles of the battery are not installed correctly, it may cause the Wanhe water heater to fail to catch fire.

It is recommended to check whether the battery is dead, and replace the battery if necessary. However, if the voltage is insufficient and the water heater does not ignite, you can check whether the AC power plug indicator is on.

3. The reason why Wanhe water heater can't catch fire - water pressure problem.

Water heaters often fail to start properly when the water pressure is too low, especially on high floors. If the water pressure is normal all the time, then look at the filter at the inlet of the water heater to see if it is causing a blockage, if so, just clean it.

Fourth, the reason why Wanhe water heater cannot catch fire - the valve seal is damaged.

The valve seal is damaged, mainly because the water heater is easy to be corroded by gas after being used for too long, and then it will swell, so the parts must be replaced.

5. The reason why Wanhe water heater can't catch fire - ignition failure.

Pulser or controller failure. If one of the pulse igniter and controller is faulty, and the water heater cannot be ignited normally, the corresponding device can be replaced.

Sixth, the reason why Wanhe water heater cannot catch fire - the heat sensing needle oxidation becomes sluggish.

If the thermal sensing needle is sluggish due to oxidation and dullness, and the Wanhe water heater cannot ignite, turn down the thermal sensing needle, wipe off the oxide layer of the sensing needle with a coarse cloth, or replace the thermal sensing needle and turn on the water heater again.

The above is about the reasons why Wanhe water heater does not catch fire and related solutions, I hope it will help you. If you encounter a water heater failure that you can't solve during the maintenance process, it is recommended that you contact professional maintenance personnel in time to come to the door for maintenance, so as not to leave potential safety hazards.

Generally, it is caused by the water heater extinguishing the fire during use, and there are usually 4 reasons and solutions for the water heater to suddenly extinguish the fire and cool the water:

1. If the water pressure is too low, the water heater will suddenly extinguish the fire; As a result, the water from the water heater becomes cold water, and if it is turned off, it will sometimes not catch fire.

2. Some water heaters are equipped with a 20-minute automatic extinguishing protection device, and the water heater will automatically extinguish the fire when the use is overtime; Generally, it is normal to extinguish the fire for 15-20 minutes, and it can be used normally when it is turned off and then turned on.

3. When the water heater is dry or the temperature is too high, the combustion will also be interrupted, resulting in the water heater extinguishing water becoming colder, and the water heater cannot catch fire when it is turned on.

Fourth, the smoke exhaust pipe of the water heater is blocked, and the flue gas cannot be discharged, resulting in large resistance in the water heater, interrupting the combustion, and it will still catch fire if it is opened again, but it will still extinguish the fire after a while.

If you still can't solve the problem, please call the official website of the water heater for repair** repair, and professionals will come to repair.
