Why no hot water?

Hi.  Mine is a Forest River Flagstaff Classic. 

It’s lovely. 

But there is no hot water. I’m sure it has inline water heater. I turn it on at the panel, it lights blue, run “hot” water…but no hot water comes out. Result:  Cold me.

i have water in my tank. But I’m also hooked up. I see no error…just no hot water.

 Then I go back and in the panel, it has turned red.  I turn it off.

Methinks this is not the Way.

 Ideas.

  • Are you familiar with the process for by-passing the water heater? By-passing the water heater is done in cold climates so that antifreeze can be pumped through the rv water system without filling the water heater with antifreeze (this is necessary so the lines don’t freeze and break). The point being, the by-pass valves need to be in a specific position to accomplish this by-pass mode. If those valves are currently in by-pass mode, you won’t get any hot water. If you don’t know about “by-passing”, google it and read up.
