The problem with the highest failure rate of gas water heaters is that the gas water heater cannot ignite. Let's take a look at the reasons why the gas water heater cannot ignite based on some of the phenomena of failure to ignite. Then come to the right medicine.
One of the reasons why the gas water heater cannot ignite is the power supply problem, whether the battery is too old. If the phenomenon occurs, check whether the AC power plug indicator light is on. If not, it means there is a power problem.
Solution: Replace the battery with a new one.
The second reason why the gas water heater cannot ignite is the solenoid valve failure. If you only hear the ignition sound when igniting, but there is no magnetic suction sound of the solenoid valve, it may be that the solenoid valve is damaged or aged. If the solenoid valve is aging, it can be closed when the ignition starts, and the ignition will start, but then it will shut down again. It may also be that the gas pressure is too high or too low. For water heaters that use cylinder gas, the output pressure of the cylinder pressure reducing valve will be too high or too low, causing the water heater to fail to ignite. There may also be dirt in the solenoid valve. If the solenoid valve cannot pass the gas, the gas cannot come out and the fire cannot be ignited. Before confirming the solenoid valve failure, you must first confirm whether the igniter control circuit is normal. If there is a fault, the solenoid valve cannot be controlled to close.
Solutions: Check and eliminate one by one to determine the specific cause. If the solenoid valve is aged, replace the solenoid valve. If there is a gas pressure problem, replace the gas bottle with a new one. If there is any dirt on the gas valve, clean it. If the ignition control circuit is faulty, repair the circuit problem.
The third reason why the gas water heater cannot ignite is the electric igniter failure. There is no ignition sound or electric spark.
Solution: Check whether one of the pulse igniter and the controller is faulty. If there is a fault, replace or repair it.
The fourth reason why the gas water heater cannot ignite is the ignition needle or induction needle problem. There is no ignition sound or electric spark.
Solution: Check whether the ignition pin is misaligned or aged. You can replace it or place the ignition pin correctly. If the induction porcelain needle is aged, the induction porcelain needle can be polished and placed as long as the flame can fully burn the porcelain needle.
The fifth reason why the gas water heater cannot start is water pressure problem. There is a slight sound of fire and sparks, which burn out quickly.
Solution: Open the faucet and check whether the water pressure is too low. If the water pressure is too low, the only way is to stagger the peak water use period.
The sixth reason why the gas water heater cannot ignite is the failure of the water-gas linkage device. There is no ignition sound or electric spark.
Solution: Check that the tympanic membrane of the water-gas linkage valve is aged or damaged and cannot push the micro switch. At this time, replace the water-gas linkage valve or repair it.

The seventh reason why the gas water heater cannot ignite is that the gas source is not turned on or the air inlet filter is blocked. There is a ignition sound but no sparks.
Solution: Turn on the air source and clean the air intake filter.
The eight reasons why the gas water heater cannot ignite are mismatched gas types. There is a slight ignition sound but no sparks.
The solution is to connect the liquefied gas water heater to natural gas, you need to change the liquefied gas water heater to a natural gas water heater before it can be connected and used.
The ninth reason why the gas water heater cannot ignite is that the valve seal is corroded and swollen by the gas. There is a ignition sound but no sparks.
Solution Replace parts.
The tenth reason why the gas water heater cannot ignite is that the exhaust pipe cannot be exhausted. There was a slight sound of fire and sparks, but they died out quickly.
Solution: The smoke pipe is blocked. Clean the pipe. If the smoke pipe is too long, reinstall it correctly.

Read the reasons why the gas water heater cannot start, what to do if the gas water heater cannot start, and the answers to the two questions. Have you checked the gas water heater at home? Now we have a preliminary judgment and solution to the cause of the failure to catch fire. No matter what, the phenomenon of failure to start the fire is something we don’t want to see, and it is also a troublesome thing. Therefore, when we buy it, we should try to choose a better brand of gas water heater to avoid this kind of gas water heater that cannot be turned on. The embarrassment of fire appears in our lives.
