If you want to understand what the fault of gas water heater is, you must first understand what is gas water heater. Experts say, gas water heater is actually we often say gas hot water furnace, it is a commonly used gas appliances, mainly to day gas to burn, by burning gas, so that you can burn the heat to cold water, the purpose is to be able to burn cold water into hot water.
This gas water heater has become the dominant force in the water heater market. Its advantage is that it is ready to use, and it is small, as long as a small piece of open land is enough. But it also has its shortcomings, that is, safety coefficient control is low, easy to some failures, below we will understand the gas water heater failure and the reason.
First, after opening the water valve pulse does not spark
Water heater failure reason analysis
l, the water pressure is too low;
2, the water filter is blocked, the shower head is blocked;
3. The positive and negative electrodes of the battery are inverted;
4, the battery voltage is too low or poor contact;
5, the water inlet and the water outlet are reversed;
Water heater maintenance method
l. Supercharging water pump;
2, remove debris;
3. Reinstall the battery;
4. Reinstall or replace the new battery;
5. Reinstall the inlet and outlet pipes;
Two, after opening the water valve pulse light but not fire
Water heater failure reason analysis
1. There is air in the trachea;
2, the battery voltage is insufficient;
3. The air source switch is not opened or the air intake filter is blocked
4, gas type is inconsistent;
5. Valve seals rise after being eroded by gas;
6, cylinder reducing valve output pressure is too high or too low;
Water heater maintenance method
1, frequent switching water valve exhaust air until fire;
2. Replace the new battery;
3. Open the air source switch completely or remove the blockage;
4, gas type does not match, prevent use;
5, replace the valve seal;
6. Check and adjust the output pressure;
Three, when burning the explosion sound
Water heater failure reason analysis
l, cylinder reducing valve pressure is too high;
2, the battery voltage is too low;
3, incineration needle carbon or dirt;
4. The location of the incineration needle is not correct or the distance from the burner is too far;
5. Incineration should be directed at the blockage of the burner hole and nozzle;
Water heater maintenance method
1. Adjust the pressure of the cylinder reducing valve;
2. Replace the new battery;
3, remove dirt;
4. Adjust the installation position of the incineration needle;
5, remove air vent and nozzle blocked debris;
Four, the use of water is not hot enough
Water heater failure reason analysis
1. The cylinder reducing valve is damaged or the gas flow is not enough;
2, the air source switch has foreign bodies or semi-blocked;
3. The gas main switch is half open;
4. The intake nozzle and trachea are too thin or the trachea is too long, resulting in insufficient air flow;
5, gas type is inconsistent;
6, the water pressure is too high, the water pressure regulator system failure;
Water heater maintenance method
1. Replace the passing pressure reducing valve;
2. Remove foreign bodies;
3. Open the main switch completely;
4. Replace the air nozzle and trachea;
5. Prevent use;
6. Half close the inlet valve to reduce the water pressure;
Five, often flameout in the course of use
Water heater failure reason analysis
1, the water pressure is low, the water pressure is bumpy;
2, indoor air to make up for the shortage;
3. Insufficient battery voltage or poor contact;
4, the water yield is too little, the water temperature is too high, the overheating device is precious;
Water heater maintenance method
l, the water twist to the appropriate position or small water position;
2. It should be installed again to ensure that the air supply is enough;
3. Replace the new battery or reinstall it;
4, the water twist to the appropriate position or flood position;
The flame was yellow and there was black smoke
Water heater failure reason analysis
1. The burner has dirt or its ejector tube has dirt;
2. Cylinder gas is used up;
3, indoor air to make up for the shortage;
4, gas type is inconsistent;
5, the air source pressure is high or low;
Water heater maintenance method
1, remove dirt, carbon;
2. Replace cylinders with liquefied gas;
3. It should be installed again to ensure that the air supply is enough;
4. Prevent use;
5, adjust or replace the passing pressure reducing valve
Understand the gas water heater failure and reason, hope everyone can do a good job of gas water heater maintenance, prevent accidents. In addition, to remind everyone that the gas water heater is safe and unlucky, so that it can not be installed by itself, it must be installed by the regular part, only gas has the safety guarantee.
