Hot water heater issues

I have looked through most of the hot water posts and cant find a answer to our problem. We have a 04 Jamboree and the hot water heater doesnt seem to stay hot. It gets almost warm and then cool again. Has anyone had this problem??? I took out the coils and cleaned them and thought that might be helpful. It starts up and you can see the pilot light. I also drained the tank thinking that might be the problem. Its is the same in all the sinks and shower. Thanks for any insight. They wanted 200 at my dealer to trouble shoot and I thought you guys might know first.

If you have an outside shower, make sure the "Hot" & "Cold" knobs are fully closed. It's possible for the hot & cold to circulate if the outside shower was just turned off at the shower head, without turning the knobs closed.

Make sure of that because it happened to me and after of several hours and a couple hundred dollars later I figured out that my problem was outside valves open. Joe

An inside shower could do the same as the outside one if the water is on but cut off at the shower head. The standard thing of unplugging and re-plugging the spade connectors on the water heater is always a good idea. Check the bypass valves. You after all of that with no joy the circuit board for the heater would be next. What I would do in any case is to install a Hott Rod electric heater in the drain plug. I have used one for many years and I don't even know anymore if my propane still would heat the water.

The way I read your post it's not burning long enough to get hot. You said it gets almost warm then cold. How's the water pressure? Like in previous post have you checked bypass valve?

Hi louboyk,
Welcome to iRV2. Suggestions about the outside shower and especially the by-pass valves are good items to check. Can you provide a little more information? Is the water heater both electric and gas or just gas powered. If on gas power and and there is a call for hot water, does the main burner light and stay lit? Check the DC voltage to the water heater and let us know what you find.

Make sure the bypass valve is shutoff. You may be pulling a mix from the cold side.
