what color is the flame? should be bluish. if yellow then burner tube needs to be adjusted. or you're running continuous hot water and the water in the tank doesn't have enough time to heat up. or bad thermostat.

My electric side didn't work well on one trip this summer, turned out the thermostat was bad. If the thermostat is bad on the gas side it will turn off the burner before the water reaches the correct temp. If you have a Suburban, they have diagnostic procedures on their web site.

I will check the flame color. We can't get it to work at all on electric side, it is a suburban 10 gal. I turned it to gas and let it run about 30 minutes before checking and it was barely above luke warm.

On the electric side, at the water heater, you can take the plastic cover off the electric probe heater to see if your getting 110v, also there is an of/off switch on the water heater itself. If you are getting 110v then the electric heating element is bad, they are pretty cheap and easy to replace.

Not much information on your coach. But I have to ask if it has a Watts mixing valve? If it does I experienced the same problem. Mine was supposed to be non-adjustable. I took it off and found they just soldered the adjusting screw so you could not adjust it, I picked the solder out and had my wife hold a thermometer under the running hot water while I adjusted it until I reached the correct temperature, that was about 5 years ago and it is still working. Not sure this is your case though.

Best bet to work through the troubleshooting systematically.

The manual should help

So, I just went thru this on a Suburban 10 gallon SW10 DEM.

Posted about it here: Suburban Hot Water Heater - How long to heat up initially and how to adjust flame?


Just got the solution today but I have not posted the update there, I will shortly with pics.

Quickly what I did, replaced the Anode and electric heating element, wanted to do anyways as I was not sure on history. Still now go.

Saw the video about the external shower head (actually got excited since I never new that could mix cold with hot) about turning off the head but keeping the faucet valves open. Was excited at first but no go. Checked bath shower head just in case, no go.

I knew cold water was being mixed with hot water, just had to find out where. Looked and finally found the bypass valve which really was in plain site , just had a couple hoses in front. For some reason, I thought the bypass valve would be next to / at the water heater. The bypass valve was next to the water manifold.

The handle was between 'bypass' and 'normal' operation (essentially at 45 degrees). Full Hot Water Now!!

That was it.

Wife can now take a Jacuzzi bath (this Coach has a jetted 'garden' tub). Happy Wife Happy Life?


I will update my original thread linked above with pictures soon.

Glad to hear you got your hot water back. No replacing Boots on the Ground.
Now you know how your hot water heater works.
