First, the igniter problem
If the pulse igniter and controller fail, one of the gas boilers will not start.
Second, the battery problem
If there is a problem with the battery, the first thing to look at is whether the battery is too old, because the voltage is not enough to make the gas boiler not catch fire.
Third, the water pressure problem
The water in the inflow of the filter in the water inlet of the gas boiler cannot flow normally, and it can be used normally after being cleaned and cleaned.
Fourth, the solenoid valve problem
If the gas boiler is ignited, only the ignition sound can be heard, and there is no magnetic sound of the solenoid valve "嗒", which may be damage or aging of the solenoid valve. When the solenoid valve is aging, it will be uncontrolled. When the fire is started, it can be sucked and hit, and it will catch fire, but then it will close and turn off. Before confirming that the solenoid valve is good or bad, make sure that the ignition control circuit is normal. Can not control the solenoid valve to pull in.
Five, ignition needle or induction needle problem
The ignition coil offset of the gas boiler can be changed or the ignition needle can be correctly placed; if the induction aging problem is solved, it is only necessary to place the induction polishing.
Sixth, the pipe can not be exhausted normally
The gas boiler pipe has an infarction, and the pipe for inflating the pipe intrusion is too long and is not properly installed. Refer to the instructions for a balanced water heater double-layer pipe installation.
Seven, water and gas linkage installation problems
In the gas boiler water-gas linkage valve, the tympanic membrane is aged or damaged, and the micro-switch cannot be pushed; the micro-switch is broken.
