Want to understand what is the gas water heater fault, you must first understand what is the gas water heater. Experts say that the gas water heater is really what we often call a gas water heater, it is a commonly used gas appliances, mainly with natural gas to burn, by burning natural gas, so that the heat from the combustion can be transmitted to the cold water, the purpose is to be able to boil cold water into hot water.
This gas water heater has become the dominant force in the water heater market now, its advantage is that it is ready to use, and Hugh small, as long as a small piece of open space is enough. But it also has its shortcomings, that is, the safety factor is low, prone to some failure, the following we will understand the gas water heater failure and the cause.
A, open the water valve after the pulse does not fire
Water heater failure cause analysis
l, the water pressure is too low.
2, the inlet water filter clogged with debris, the shower head clogged with debris.
3, the battery positive and negative poles installed in reverse.
4, the battery voltage is too low or poor contact.
5、Water inlet and outlet are connected backwards.
Water heater repair mode
l、Add booster pump.
2, get rid of debris.
3、Reinstall the battery.
4、Reinstall or replace the new battery.
5、Reinstall the inlet and outlet pipes.
Second, open the water valve after the pulse fire but not on fire
Water heater failure cause analysis
1、Air in the gas pipe.
2, the battery voltage is insufficient.
3, the gas source switch is not open or into the air filter blockage
4, gas species does not match.
5、The valve seal is eroded by the gas after the rise.
6, cylinder pressure reducing valve output pressure is too high or too low.
Water heater repair mode
1、Switch the water valve frequently to discharge air until the fire.
2、Replacement of new batteries.
3, the gas source switch all open or remove the blockage.
4、Gas species does not match, prevent the use of.
5, replace the valve seals.
6, check and adjust the output pressure.
Third, the combustion of the sound of explosive combustion
Water heater failure cause analysis
l, cylinder pressure reduction valve is too high.
2, the battery voltage is too low.
3, incineration needle carbon or dirt.
4, incineration needle is not properly positioned or too far away from the burner.
5, burning needle corresponding to the burner hole, nozzle blockage.
Water heater repair method
1, adjust the pressure of the cylinder pressure reducing valve.
2、Replacement of new batteries.
3、Eliminate the dirt.
4、Adjust the burning needle installation position.
5、Remove debris from the air outlet and nozzle blockage.
Fourth, the use of the course of the water is not hot enough
Water heater failure cause analysis
1, cylinder pressure reducing valve damage or gas flow is not enough.
2, the gas source switch has a foreign body or half blockage.
3, the gas switch half open.
4, into the gas nozzle, gas pipe is too thin or gas pipe is too long caused by insufficient gas flow.
5、The gas does not match the type of gas.
6, the water pressure is too high, water pressure stabilization system failure.
Water heater repair method
1, replace the qualified pressure reducing valve.
2, remove foreign objects.
3、Open the valve all.
4、Replace the air nozzle, air pipe.
5、Stop the use.
6、Close the water inlet valve half to reduce water pressure.
Five, the use of the course of frequent flameout
Water heater failure cause analysis
1, low water pressure, water pressure fluctuations.
2, indoor air to make up for insufficient.
3, insufficient battery voltage or poor contact.
4, the water output is too little, the water temperature is too high, the overheating device to cherish.
Water heater repair mode
l, the water twist to the appropriate position or small water position.
2, should be re-installed to ensure that the air is enough to make up enough.
3、Replace the new battery or reinstallation.
4、Turn the water to the appropriate position or flood position.
Six, the flame is yellow flame and black smoke
Water heater failure cause analysis
1, the burner has dirt or its pilot tube has dirt.
2, cylinder gas used up.
3, indoor air to make up for the lack of.
4, gas species does not match.
5、Gas source pressure is high or low.
Water heater maintenance method
1、Remove dirt, carbon.
2、Replace the cylinder with liquefied gas.
3, should be re-installed to ensure that the air is enough to make up enough.
4、Stop the use.
5、Adjust or replace the qualified pressure reducing valve
Understand the gas water heater failure and the cause, I hope everyone can do a good job of gas water heater maintenance, to prevent accidents. In addition, remind everyone is that gas water heaters safe and obscure, so you can not be installed by yourself, you must be installed by the regular parts, in order to have a safe and secure.
