Strange field water heater won't catch fire?

A, question for power supply

Water heater can't fire solution: check the ac power plug lights are bright, to rule out power supply part of the question.

Second, the electromagnetic valve failure

Water heater can't fire the solution: if only heard burning burning, no \"click\" magnetic absorption electromagnetic valve, may be electromagnetic valve damage or aging, aging of the solenoid valve, will not be controlled, can suck at the beginning of the lighter one, played on fire, but immediately closed stalled again; May also for the gas pressure is too high or too low, using cylinder gas water heater will appear the cylinder pressure reducing valve output pressure too high or too low to use water heater can't play on fire; Is more likely for the solenoid valve with dirt. Electromagnetic valve cannot pass gas, gas, natural gas, liquefied petroleum gas, artificial coal gas) will not be able to come out, can't come out, so that doesn't work. Before confirm the solenoid valve is good or bad to confirm incinerator control circuit is normal, if there is failure, unable to control the electromagnetic valve and off.

Three, the electric fault incinerator

Water heater can't fire solution: pulse burning and controller one party has fault, water heater is not burning.

Four: burning or induction porcelain porcelain needle

Water heater can't fire the solution: a. pin offset or aging burned very difficult, can replace or would fire needle was right; B. induced aging, can be induced to polish stow (regardless of the flames of the fire or a small fire can be fully burning sensing needle).

Five, the water pressure

Water heater can't fire solution: a. water down when the water heater can't normal boot;

B. filter clogging caused water to flow through water, clean can.

Six, moisture linkage of failure

Water heater can't fire solution: a. moisture linkage cannot push valve inside tympanic membrane aging or damage to the micro switch;

B. micro switch bad.

Seven, air switch is not open or inlet filter clogging

Water heater can't fire solution: open air supply, air intake filter.

Eight, gas

Water heater can't fire the solution: such as liquefied petroleum gas water heater from natural gas quality, p after this kind of situation need to be liquefied gas to natural gas water heater can use access.

After nine, valve seal gas corrosion was risen.

Water heater can't fire solution: replacement parts.

Ten, normal exhaust pipe can't

Water heater can't fire solution: a. pipe jam, finishing a pipe blockage; B. a pipe is too long, not installed correctly.
