Although the gas water heater is not a precision instrument, it will cause it to work normally in many aspects.Similar problems such as gas water heaters turn off the fire or the gas water heater cannot hit fire, and often plague users.As long as you know more and learn more, many problems that occur in gas and gas water heaters can be solved by yourself, but you must first ensure the safety of life.
Gas water heater repair
1. Battery problem.Gas water heaters need to use batteries to fire, but the use time is too long and the voltage is not enough, so there will be a problem of fire.
2. Discipline of solenoid valve.If you only hear the sound of ignition when you ignite, there is no magnetic absorption of the solenoid valve, which may be damaged or aged by the solenoid valve. The solenoid valve is aging and will not be controlled.It was closed and turned off again; before confirming the quality of the solenoid valve, it was necessary to confirm whether the ignition control circuit could be normal. If there was something wrong, the solenoid valve was not controlled.
3. Origator problem.As long as one side of the pulse ignition or a controller fails, the gas water heater cannot be started normally.
4. ignition needle or induction needle problem.The point of the ignition needle can be replaced or the ignition needle is properly placed; if the aging problem of the induction, just put the induction light and put it.
5. Water pressure problem.When the heat exchangers water inlet filter infarction causes the water flow cannot be passed, it can be used normally if it is cleaned.
6. Water and gas linkage installation.The inner drums or damage of the water and gas linkage valve cannot promote the micro -switch; the micro switch is broken.
7. The tobacco pipe cannot be exhausted normally.There are infarction in the cigarette pipe, and the smoke pipe infarction of the smoke pipe is too long, and there is no correct installation.References can be referred to the two -layer cigarette pipe device of the equalized water heater.
8. The valve seal is corroded by the gas and rose.Replace parts.
Rule of use
1. Out off in use
1. The valve of the gas is not all opened.
Treatment method: Open all the gas valve.
2. Gas pressure is not suitable, too low.
Treatment method: continuously switch the hot water system until the fire.Maintenance personnel check the pressure reduction valve.
3. Cold water pressure is too low.
Treatment method: Maintenance personnel check the water pressure.If you start the water pressure 0 0.035MP and there is such a situation, you should adjust the water volume control screw under the gas valve, and adjust the water output.
4. Safety device action.
Treatment method: Please refer to the method of processing the safety device.

Treatment method: Maintenance personnel change pulses.
8. Loat of the lead.
Treatment method: Correctly connect the loose lead.
9. Electric valve failure.
Treatment method: Maintenance personnel inspection.
10. Flame probe failure.
Treatment method: Maintenance personnel inspection.
2. Do not get angry after opening the water heater
1. The valve of the gas is not opened.
Treatment method: Open all the gas valve.
2. There is air in the gas pipe.
Treatment method: continuously switch the hot water system until the fire.
3. The cold water general valve is not opened.
Treatment method: Full the cold water general valve.
4. Water pipe freeze.
Treatment method: It can not be used until it melts.
5. Cold water pressure is too low.
Treatment method: Maintenance personnel check the water pressure.
6. Safety device action.
Treatment method: Please refer to the method of processing the safety device.
7. Dry battery is out of power.
Processing method: Replace new dry batteries.
8. Water controller fails.
Treatment method: Maintenance personnel handling.
9. Pulse failure.
Treatment method: Maintenance personnel change pulses.
10. Loat of the lead.
Treatment method: Correctly connect the loose lead.
11. Micro switch failure.
Treatment method: Maintenance personnel inspection.
12. Electric valve failure.
Treatment method: Maintenance personnel inspection.
13. The battery positive and negative polarity is connected.
Processing method: The battery is installed correctly.
3. Broken ignition
1. The valve of the gas is not all opened.
Treatment method: Open all the gas valve.
2. The gas pressure is not suitable, too high.
Treatment method: continuously switch the hot water system until the fire.
4. Flame yellow smoke appears
1. Cover inside the burner.
Treatment method: Maintenance personnel clean up the debris in the burner.
2. The heat exchanger is blocked.
Treatment method: Maintenance personnel clean up carbon accumulation in the heat exchanger.
5. Flame abnormally with odor
1. Insufficient fresh air supply.
Treatment method: Immediately improve the ventilation so that there is enough fresh air.
2. Cover in the burner.
Treatment method: Maintenance personnel clean up the debris in the burner.
3. The heat exchanger is blocked.
Treatment method: Maintenance personnel clean up carbon accumulation in the heat exchanger.
6. There is an abnormal noise when igniting
1. The gas pressure is not suitable, too high.
Treatment method: continuously switch the hot water system until the fire.
2. Insufficient fresh air supply.
Treatment method: Immediately improve the ventilation so that there is enough fresh air.
3. Cover in the burner.
Treatment method: Maintenance personnel clean up the debris in the burner.
Seven, adjust to high temperature positions, water is still not hot
1. The valve of the gas is not all opened.
Treatment method: Open all the gas valve.
2. Gas pressure is not suitable, too low.
Treatment method: continuously switch the hot water system until the fire.
3. Water temperature adjustment method error.
Treatment method: Refer to the hot water temperature adjustment of the instruction manual.
4. Water controller fails.
Treatment method: Maintenance personnel handling.
8. The water is too hot when the low temperature is located
1. Water temperature adjustment method error.
Treatment method: Refer to the hot water temperature adjustment of the instruction manual.
2. Water controller fails.
Treatment method: Maintenance personnel handling.
Nine, the fire goes off when the low temperature is located
Reason: Cold water pressure is too low.
Treatment method: Maintenance personnel check the water pressure.
10. The fire is immortal after turning off the water heater
Reason: Water controller fails.
