Gas water heater failure and repair methods

If you want to know what gas water heater failures are, you must first understand what a gas water heater is. Experts say that a gas water heater is actually what we often call a gas water boiler. It is a commonly used gas appliance that mainly burns natural gas. By burning natural gas, the heat generated by the combustion can be transferred 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 current water heater market. Its advantages are that it can be used immediately after being turned on and it takes up little space, so it only needs a small piece of open space. However, it also has its shortcomings, that is, the safety factor is relatively low and it is prone to some failures. Let us now understand the failures and causes of gas water heaters.

1. The pulse does not ignite after opening the water valve

Analysis of water heater failure causes

l. The water pressure is too low;

2. The water inlet filter is clogged with debris, and the shower head is clogged with debris;

3. The positive and negative poles of the battery are installed in reverse;

4. The battery voltage is too low or the contact is poor;

5. The water inlet and outlet are connected in reverse;

Water heater maintenance method

l. Add a booster water pump;

2. Clear away debris;

3. Reinstall the battery;

4. Reinstall or replace the battery;

5. Reinstall the inlet and outlet pipes;

2. Pulse ignition but no fire after opening the water valve

Analysis of water heater failure causes

1. There is air in the trachea;

2. The battery voltage is insufficient;

3. The air source switch is not turned on or the air inlet filter is blocked

4. The gas type does not match;

5. The valve seal swells after being corroded by gas;

6. The output pressure of the cylinder pressure reducing valve is too high or too low;

Water heater maintenance method

1. Repeatedly open and close the water valve to exhaust air until the fire occurs;

2. Replace the battery with a new one;

3. Fully open the gas source switch or clear the blockage;

4. If the gas type does not match, it is prohibited to use;

5. Replace the valve seal;

6. Check and adjust the output pressure;

3. Explosion sound occurs during ignition

Analysis of water heater failure causes

l. The pressure of the cylinder pressure reducing valve is too high;

2. The battery voltage is too low;

3. The ignition needle has carbon deposits or dirt;

4. The ignition needle is not in the correct position or is too far away from the burner;

5. The burner hole and nozzle corresponding to the ignition needle are clogged;

Water heater maintenance method

1. Adjust the pressure of the cylinder pressure reducing valve;

2. Replace the battery with a new one;

3. Remove dirt;

4. Adjust the installation position of the ignition needle;

5. Clear the debris that clogs the air outlet and nozzle;

4. The water is not hot enough during use

Analysis of water heater failure causes

1. The cylinder pressure reducing valve is damaged or the gas flow is insufficient;

2. The gas source switch has foreign matter or is half blocked;

3. The main gas switch is half open;

4. The air inlet nozzle or air pipe is too thin or the air pipe is too long, resulting in insufficient air flow;

5. The gas type does not match;

6. The water pressure is too high and the water pressure stabilization system fails;

Water heater maintenance method

1. Replace the qualified pressure reducing valve;

2. Remove foreign matter;

3. Turn on the main switch;

4. Replace the air nozzle and air pipe;

5. Prohibited use;

6. Half-close the water inlet valve to reduce the water pressure;

5. Frequent flameout during use

Analysis of water heater failure causes

1. Low water pressure and large water pressure fluctuations;

2. Insufficient indoor air supply;

3. The battery voltage is insufficient or the contact is poor;

4. The water output is too little, the water temperature is too high, and the overheating device is in protection;

Water heater maintenance method

1. Adjust the water knob to the appropriate position or low water position;

2. Reinstall to ensure sufficient air supply;

3. Replace the battery with a new one or reinstall it;

4. Adjust the water knob to the appropriate position or the high water position;

6. The flame is yellow with black smoke

Analysis of water heater failure causes

1. There is dirt in the burner or its ejector tube;

2. The cylinder gas is used up;

3. Insufficient indoor air supply;

4. The gas type does not match;

5. The gas source pressure is too high or too low;

Water heater maintenance method

1. Remove dirt and carbon deposits;

2. Replace the cylinder with liquefied gas;

3. Reinstall to ensure sufficient air supply;

4. Prohibited use;

5. Adjust or replace the qualified pressure reducing valve

Now that we know about the failures and causes of gas water heaters, we hope that everyone can do a good job of maintaining the gas water heaters to avoid accidents. In addition, we would like to remind everyone that gas water heaters are unsafe and inconvenient, so they cannot be installed by yourself. They must be installed by a formal location to ensure safety.
