All kinds of electrical appliances are used at home, and there are always all kinds of faults in electrical appliances. Water heaters are used by us every day, and the usage rate is very frequent, so there will always be various problems, such as non ignition. What's the reason for non ignition? Let's see what's the reason for the non ignition of water heaters.
The seller will tell you how to use the water heater most correctly when you buy it, so even if there is a problem with the water heater, you need to find a professional person to repair it. If you don't know how to do it by yourself, it will cause accidents.
1. Power supply problem: check whether the indicator light of the AC power plug is on, and first eliminate the problem of the power supply part;
2. Solenoid valve failure: if only the ignition sound is heard during ignition, and there is no solenoid valve "Ta" magnetic absorption sound, it may be:
A. if the solenoid valve is damaged or aged, the solenoid valve will be out of control. It can be pulled in at the start of the ignition and ignited, but then it will be closed and extinguished;
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 to ignite;
C. the solenoid valve is dirty. If the solenoid valve is not allowed to pass through the gas, the gas (natural gas, liquefied petroleum gas, artificial gas) will not come out and cannot come out, so that it will not ignite. Before confirming the quality of the solenoid valve, confirm whether the control circuit of the igniter is normal. If there is a fault, the solenoid valve cannot be controlled to close.
3. Electric igniter failure: one side of the pulse igniter and controller has failure, and the water heater fails to ignite normally;
4. Ignition or induction ceramic pin problems;
There are many reasons for the problem of water heater. We need to look at it from a professional point of view. At ordinary times, we need to do more inspections and scrubbing for the electrical appliances at home. When there are insufficient places, we need to properly change them so that we can be assured when using them, and the probability of the problem is smaller than before, so we must check and care more if we want to avoid the problem of water heater.
