What's the reason why the water heater won't start?

Five reasons why your water heater won’t start: Gas supply problems, such as closed pipes or insufficient gas. The igniter or spark plug is faulty, resulting in the inability to produce spark. Circuit problems, such as damaged power cords or abnormal control circuits. Insufficient water pressure, water supply pressure is too low or the filter is clogged. Other causes such as blocked flue, faulty thermistor or scaled water tank.

The reason why the water heater cannot start on fire

When the water heater cannot start on fire, it may be caused by the following reasons:

1. Gas supply problem

• Is the gas pipeline open?
• Is the gas supply sufficient?
• Is the gas meter working properly?

2. Ignition failure

• Is the ignition damaged or malfunctioning?
• Is the connection between the igniter and spark plug normal?
• Are the spark plugs clean?

3. Circuit problem

• Is the water heater powered on?
• Is the power cord damaged?
• Is the control circuit normal?

4. Insufficient water pressure

• Is the water supply pressure too low?
• Is the filter clogged?

5. Other reasons

• The flue is blocked and the exhaust gas cannot be discharged
• The thermistor failure causes the water temperature to be unable to be detected
• Excessive scaling in the water tank leads to a decrease in heat transfer efficiency

Troubleshooting steps:

1. Check the gas supply
2. Check the ignition and spark plug
3. Check the circuit and power supply
4. Check the water pressure
5. Exclude other possible causes
