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、水压太低；
2、水过滤器堵塞、花洒头堵塞；
3. The positive and negative electrodes of the battery are inverted;
4、电池电压过低或接触不良；
5, the water inlet and the water outlet are reversed;
热水器保养方法
l. Supercharging water pump;
2、清除杂物；
3.重新安装电池；
4. Reinstall or replace the new battery;
5、重新安装进、出水管；
Two, after opening the water valve pulse light but not fire
Water heater failure reason analysis
1. There is air in the trachea;
2、电池电压不足；
3、气源开关未打开或进气过滤器堵塞
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;
热水器保养方法
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、更换阀门密封圈；
6、检查、调整输出压力；
Three, when burning the explosion sound
Water heater failure reason analysis
l, cylinder reducing valve pressure is too high;
2、电池电压过低；
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;
热水器保养方法
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、气源开关有异物或半堵塞；
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、水压过高，水压调节系统故障；
热水器保养方法
1. Replace the passing pressure reducing valve;
2、清除异物；
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;
热水器保养方法
l、将水扭至适当位置或小水位置；
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;
热水器保养方法
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.
