1, the power problem, the battery is too old.

Phenomenon: check whether the AC power plug indicator is on. If it is not lit, it is a power supply problem.

The solution: replace the new battery.

2. The malfunction of the solenoid valve.

Phenomenon: if the ignition is heard at the time of ignition, there is no electromagnetic sound of "clicking", which may damage or aging the solenoid valve. If the solenoid valve is aging, it can be caught and caught on fire when it starts, but then it will go out again. It may also be too high or too low for gas pressure, and the cylinder gas water heater will appear to be too high or too low in the cylinder pressure relief valve, causing the water heater to fail to catch fire. It is also possible for the solenoid valve to have dirt. The solenoid valve can not pass through the gas, so that the gas can not come out, so that the ignition does not catch fire. Before confirming the failure of the solenoid valve, it is necessary to confirm whether the igniter control circuit is normal. If there is a fault, the solenoid valve can not be controlled.

Solution: check the exclusion method to determine the specific reasons. If the solenoid valve is aging, the solenoid valve is replaced. If the gas pressure is a problem, replace the new gas cylinder. If the gas valve has stolen goods, it is cleaned up. If ignition control circuit, the maintenance circuit problem.

3. Fault of electric igniter.

Phenomenon: there is no ignition and electric spark.

Solution: check whether the pulse igniter and the controller have a fault on one side, or replace or repair in case of malfunction.

4, the problem of ignition porcelain needle or induction porcelain needle.

Phenomenon: there is no ignition and electric spark.

Solution: check whether the ignition needle is partial or aging, replace or set the ignition needle correctly. If the induction porcelain needle is aging, the induction porcelain needle can be polished and placed as long as the flame can fully burn the porcelain needle.

5. Water pressure.

Phenomenon: there are ignition sounds and sparks, which burn up quickly.

Solution: turn on the tap to check if the water pressure is too small. If the water pressure is too small, only stagger the peak period of water use.

6, water gas linkage device failure.

Phenomenon: there is no ignition and electric spark.

Solution: check the aging or damage of the tympanic membrane in the water gas linkage valve, do not push the micro switch, then change the water gas linkage valve or repair.

7. The gas source is not open or the intake filter is blocked.

Phenomenon: there is no spark in the sound of ignition.

Solution: open the gas source and clean the intake filter.

8, the gas is not consistent.

Phenomenon: there is the sound of ignition and no electric spark.

Solution: if the LPG water heater is connected to natural gas, it is necessary to convert the LPG water heater into a natural gas water heater before it can be used.

9. The valve seal is corroded by gas corrosion.

Phenomenon: there is no spark in the sound of ignition.

Solution: replacement parts.

10, the exhaust pipe can not exhaust.

Phenomenon: there are ignition and electric sparks, but they will soon die out.

The solution: the pipe is blocked and the pipe is cleaned. If the pipe is too long, it will be installed again correctly.
