Water heater problems?

[Steve62758]

I have a 2010 Revolution with Aqua Hot and a all electric hot water heater. We have no problems with it till this morning. Since we are currently hooked up to 50 amp service I have had the Aqua Hot turned off and have been using the Electric heater, this morning half way through my wife's shower the hot water ran out. I switched the Aqua Hot system on and now we can not get any hot water at all. Any clues ?

Thanks

If you have an Atwood water heater in your system, then the mixing valve my be the problem. First, check the temp of your water by opening the relief valve at the water heater. Be very careful as the temp is about 150 degrees. If the water is hot then the mixing valve has clogged up. The valve is behind the water heater (my 07 bounder is in the closet) and it is big and made of copper. If you are handy you can disconnect, unscrew, and empty the stuff out of it ( of course the water heater has to be empty and off). It cost me about $400 to figure this out last Winter--long story.

It seems odd that neither the Aquahot nor the Atwood heater can deliver hot water. That points to maybe some valve or Tee that is common to both systems, rather than a Atwood heater problem.

Has the Aquahot worked ok for hot water before this?

The common part is the mixing valve on the back of the water heater. If it is clogged then you will only get cold water from the system. Very simple to check, just find the back of the water heater and take it apart.

Thanks for the responses, I drained the hot water out of the system and that seems to have made everything ok. Both the Aqua Hot and the Elect. hot water heater are working now. Does anyone know where the elect. hot water headed is located in this coach. I have looked in all the normal places and can't locate it.

Perhaps your Aqua Hot system provides both heat and hot water for your coach and you do not have a separate hot water heater?

It would be unusual to have both an Aquahot and a separate water heater. Needless duplication, but long ago I learned that Rvs often do things that don't make much sense.
