Gas water heater does not ignite

In today's households, as long as natural gas is installed, the water heaters at home will not use power-consuming water heaters. After all, electricity bills are much more expensive than gas bills. However, when using a gas water heater, a problem that is very likely to occur is quite annoying, that is, the gas water heater fails to ignite. In order to help you solve this problem, here we will introduce to you the possibilities of why the gas water heater may not ignite.

It is a very common problem that the gas water heater fails to ignite. The reasons that lead to this situation can be roughly divided into ten types, each with different solutions. For example, water pressure, power supply, solenoid valve, etc. can cause the water heater to fail to ignite.

1. Power supply problem

Solution to the problem of the water heater not igniting: Check whether the indicator light of the AC power plug is on, and eliminate the problem of the power supply first.

2. Solenoid valve failure

Solution to the problem that the water heater cannot ignite: If only the ignition sound is heard when igniting, but there is no "click" magnetic suction sound of the solenoid valve, the solenoid valve may be damaged or aged. An aged solenoid valve will be out of control. It can be attracted and ignited at the beginning of ignition, but it will close and go out again. It may also be that the gas pressure is too high or too low. For water heaters using cylinder gas, the output pressure of the cylinder pressure reducing valve will be too high or too low, and the water heater cannot ignite. It is more likely that there is dirt in the solenoid valve. If the solenoid valve cannot pass gas, the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, and the fire cannot be ignited. Before confirming whether the solenoid valve is good or bad, you must confirm whether the ignition control circuit is normal. If there is a fault, the solenoid valve cannot be controlled to close.

Three: Electric igniter failure

Solution to the problem that the water heater cannot ignite: If one of the pulse igniter and the controller is faulty, the water heater cannot ignite.

4. Problems with ignition porcelain needle or induction porcelain needle

Solutions to the problem that the water heater cannot ignite: a. When the ignition needle is misplaced or aged, ignition is very difficult. You can replace the ignition needle or place it correctly. b. The sensor is aged. You can polish the sensor and place it properly (so that the flame can fully burn the sensor needle regardless of whether it is a high fire or a low fire).

5. Water pressure problem

Solutions to the water heater not starting: a. The water heater cannot start normally when the water pressure is low;

b. The filter at the water inlet is clogged, causing water to not flow through normally. Just clean it.

Regarding the reasons why the gas water heater fails to ignite, this article will first introduce the above 5 reasons. There are also other reasons such as inconsistent gas types and exhaust obstruction of the smoke pipe, which can cause it to fail to ignite. As long as you check them one by one, you can definitely solve the problem of the gas water heater failing to ignite and allow your family to use hot water.
