A gas water heater may be difficult to ignite for a variety of reasons:
Air valve is not opened or not open enough: gas water heaters need sufficient gas supply to ignite, if the air valve is not opened or not opened enough, it will lead to ignition difficulties. Check that the gas valve is open and the gas line is smooth.
Gas line blockage: There may be impurities or dirt buildup in the gas line, resulting in poor airflow. It is necessary to clean the gas line and remove the blockage.
Water heater parts damage: water heater ignition requires multiple parts to work together, if one of the parts is damaged or aging, it will also lead to ignition difficulties. Need to check the gas burner, ignition device, solenoid valve and other parts of the working condition, and repair or replace.
Insufficient gas pressure: If the gas pressure is too low, the water heater will not ignite. Check the gas meter pressure to ensure that it meets the requirements of the gas water heater.
Before solving the problem, it is necessary to close the gas valve and ensure that there is no open flame or other ignition source. If the above methods cannot solve the problem, it is recommended to contact a professional gas water heater maintenance personnel for inspection and repair.
There are many reasons why the ignition of gas water heaters is difficult, such as the air valve is not opened, the gas line is blocked, the ignition electrode is damaged, and so on.
2 Specifically, it may be that a component inside the gas water heater is faulty or damaged, causing ignition difficulties.
For example, the ignition electrode is contaminated or worn, causing the spark to fail to ignite the gas properly.
In the gas pipeline, the valve is not opened, the pipeline is blocked, etc., which will also affect the gas supply, resulting in ignition difficulties.
3 If the ignition of the gas water heater is difficult, you can first check whether the gas valve is open, whether the gas pipeline is smooth, you can also clean the ignition electrode and other components, or seek the help of professionals to solve the problem.
1, when the gas water heater does not ignite, it may be that its solenoid valve is faulty, once the gas water heater does not ignite, we can directly listen to the solenoid valve has a magnetic sound, if not, it is likely to be damaged, the solenoid valve once aging will not be controlled by any, so it will certainly not be hit in the ignition.
2, it is also possible that the igniter failure, if its igniter once blocked, there will be such problems.
3, it may also be caused by a problem with the ignition magnetic needle and induction tile.
4, there is another reason, may be that the water heater has no electricity, the water heater needs to put the battery, we can check the water heater, if there is no electricity, it can not catch fire.
Causes and solutions
1. Power supply problem
Solution: Check whether the AC power plug indicator is on, and first eliminate the problem of the power supply.
2. The solenoid valve is faulty
Solution: If the ignition only hears the ignition sound, there is no magnetic valve \"click\" magnetic absorption sound, the solenoid valve may be damaged or aging, the solenoid valve aging, will not be controlled, at the beginning of the ignition can be sucked under one, hit the fire, but then closed and turned off; It may also be that the gas pressure is too high or too low, and the water heater using cylinder gas will appear that the output pressure of the cylinder pressure reducing valve is too high or too low. More likely there's dirt on the solenoid valve. Solenoid valve can not pass gas, gas (natural gas, liquefied petroleum gas, artificial gas) can not come out, can not come out, so that the point does not fire. Before confirming the quality of the solenoid valve, it is necessary to confirm whether the igniter control circuit is normal. If there is a fault, it cannot be controlled by the magnetic valve.
Reason: First, check whether the battery has electricity, if the battery has no electricity, it will show that the ignition is weak or not ignited at all, and the replacement of the battery can generally be solved. Second, the inlet pressure is too low. Now the gas water heater can start with low water pressure, but if the water pressure is too low, the water gas linkage valve will not start, which is not a spark. Of course, the blockage of the filter at the water inlet will also cause the water flow to be too small, just clean up.
Third, the water pressure diaphragm of the water gas linkage valve is aging. The aging and loss of elasticity of the water pressure diaphragm will cause the slider to be flexible, and even if the water pressure is normal, the gas will not pass, which means that the first time can be used normally, but the second time will be used after a period of time, such as the normal return of the slider to ignite, or it can not ignite at all.
