If you are having trouble lighting your water heater, several possible causes exist. Here are a few steps you can take to troubleshoot and ensure your water heats properly:
- Propane supply: Ensure the propane tank is turned on, and enough propane is in the tank. You can also try lighting a stove burner to check if the gas is flowing correctly.
- Thermocouple: It is a device for ensuring safety that senses the pilot flame and prevents propane from flowing. Ensure the thermocouple free is properly positioned. Cleaning requires a soft cloth or fine steel wool if it is dirty.
- Spark igniter: If the sparking function fails, the igniter should be replaced.
- Valve: The valve controls the flow of propane to the burner. Confirm that it is set on the “on” position and functioning. If not, consider replacing it.
- Air in the line: If there is air, it can inhibit the pilot from lighting. To purge air, flick off the valve, wait a few minutes, and then turn it back on. Repeat this process a few times to clear the air.

- Poor water quality: There may be sediment buildup if your water is discolored, smells unpleasant, or tastes odd. Drain and flush the tank to eliminate any mineral buildup or sediment to fix this.
- Water leaks: These could result from a faulty pressure relief valve or a loose or damaged drain plug. Tighten these parts after checking them and consider replacing them when necessary.
- Overheating: A broken thermostat or a temperature and pressure relief valve may cause water overheating in the tank. Replace these parts as necessary.
- Noisy operation: If it makes unusual noises, there could be sediment, debris, or minerals buildup in your water heater tank. To get rid of any accumulation, drain and flush the tank.
- The pilot light won’t stay lit: A dirty pilot assembly may cause the pilot light’s recurrent outages. To resolve this problem, clean the assembly by the user manual.
