How to Troubleshoot a RV Propane Water Heater
Your RV's water heater is responsible for warming the water that enters your RV through the water connection, providing you with hot water for showering and washing dishes. If your water heater is not working properly, it is important to determine whether the issue is due to the propane supply or a mechanical problem within the heater.
Lack of Hot Water
One of the first signs that there is a problem with your water heater is when you turn on your shower and find that you have no hot water. First, check to ensure that no other faucets are running at the same time. The next step that you should take is to check the tank. Touch it to see if it is warm to the touch. If the tank is warm, check the positioning of the valves along the pipes. Make sure that the water heater bypass valve is not directing water away from the water heater.
Propane Heater Will Not Light
If you are having trouble lighting the pilot light on your water heater, take the time to clean out the propane jet that supplies the pilot light with fuel. Once the propane jet is cleaned, the pilot light should function. If the pilot light still will not work, take a look at the wire connections. Ensure that the wires are in good condition and free of any fraying or damage. If the wires appear to be in good shape, it is a good idea to hire a professional to step in and take a look at the propane heater.
Foul Smell
A foul smell can signal the presence of bacteria in the tank of the water heater. Drain the tank and clean it using a solution of chlorine and water. Once the tank is cleaned, you can refill it and turn the water heater back on. You can prevent bacteria buildup by carefully storing your water heater during the winter seasons. Ensure that the tank of the heater is empty and completely dry prior to storing.
Strange Noise
If you notice a strange rattling or noise coming from your water heater, this can signify an issue with the air flow within the heater. The air mixing gate allows gas to enter the burner tube while controlling the flow of air to properly stir the propane. In most cases, the noise can be rectified simply by adjusting the handle that controls the air mixing gate.
