There is something wrong most are to hot.Try in other mode,either electric or gas. Service under warranty is probably needed

Rob,

I just answered a similar question over on SOITC's forums. It may be a coincidence, but this question of yours is almost identical to the one over there.

Look for a hot water heater bypass filter in the area of the underbelly where the water manifold is located. If you are also an SOITC member, the answer over there even has a photo included to give one an idea of where it is located.

Since it isn't real easy for me to post pictures here, below is a link to my Photobucket account showing the water manifold, water filter housing, and the bypass valve. The valve is located to the right of the water filter housing in that picture. That valve turns 90 degrees to open or close.

We had a similar issue as yours when we first got our Mobile Suites, and since I had never had a coach or camper with a bypass valve, I had no clue. What "hot" water I was getting was what was generated by the sun shining on 100' of water hose. I asked on SOITC, got an answer about the bypass valve, turned it and I had hot water.

Thanks Terry for the info and yes it was me posting on the other forum. Always not sure what is the best forum to ask the questions.

another cause of luke warm water is if the outside shower valves are turned on and the shower turned off using the button on the shower head. This will cause the cold and hot sides to mix. Just another place to check if your coach is equipped this way.

ps: I suppose the inside shower in the bathroom could do the same thing so check it too
