What's wrong with the water heater not turning on the light?

There may be many reasons why there is no ignition after replacing the water heater. Let's analyze several common situations.

1. Improper operation

After replacing the water heater, first check whether it is operated correctly according to the instructions. If the operation is wrong, it may lead to failure to ignite. The correct operation flow is: first set the gas valve and water valve to the closed state, then set the gas switch to the closed position, then connect the natural gas pipeline and the cold water pipeline, turn on the gas switch in turn after opening the water valve, and then ignite. If the operation is improper and the gas cannot circulate smoothly when the gas switch is turned on, then the ignition cannot be started.

2. Gas pipeline failure

There is no ignition after changing the water heater, which may be a gas pipeline failure. For example, the leakage of gas storage in the pipe or the looseness of the interface will easily lead to unstable airflow, which will lead to ignition problems. The solution is to check the gas pipeline and replace the gas pipe fittings if necessary.

3. The throttle hole is blocked.

Throttle is an important part of gas water heater. Combustion is formed by mixing air and natural gas. If there is dirt or dust in the orifice, it will lead to insufficient gas flow. If the throttle is blocked, you can't catch fire. The solution is to clean the orifice with detergent to ensure smooth gas circulation.

4. Battery problems

At present, most gas water heaters are equipped with batteries to supply power to ignition devices. If the battery power is insufficient or the battery contact is poor, then you can't strike a fire. The solution is to replace the battery or adjust the battery position.

In short, there may be many reasons for not igniting after changing the water heater, which is not a simple problem. After replacing the water heater, users should carefully check every link and operate the gas water heater correctly to avoid unnecessary losses. If you can't solve it yourself, it is recommended to consult a professional.
