Water Heater on Propane.

The switch outside the RPOD in the heater compartment is for 120v heat only.  A good test of the heater is to hook up to shore power, run water through the lines to make sure the 6 gal heater tank is full, turn on the electric switch and you should have hot water.  Yes you need to turn on the water pump to get that hot water to run through the faucet if you are not connected to city water and are using the water from your fresh water tank.  If that works, then shut everything down and attempt to use the propane again by only turning on the hot water from the inside switch.  A little red light should come one as it tries to light and will go off when lit.  If it does not light the unit will make two more attempts to light.  If the water heater does not come on the light will stay lit.  You can use only electricity to heat the water if you are camping with electric hookup.  But if boondocking you are out of luck and need to run on propane.  Ours broke while on a trip and had to be repaired under warranty but I do not know what was wrong with the propane part of the system while the 120v worked fine.  It seems it is not uncommon to have the propane part break.

I would recommend doing the following. Have someone inside, turn on the water heater switch while you are outside with the vent cover open. When switch turns on, Do you smell propane ? yes/no.  Do you hear a clicking sound ? yes/no. If you smell propane, but it doesnt light, you have an ignition problem and everything else is good. Next I would remove the small circuit board that is attached to the water heater, either under the bed or dinette. (it's usually wire tied or some really chincy way to the unit. Bring that board to the dealer to test. It might be inside a small box like enclosure. As far as do you have water in the water tank, Pull the emergency pressure release valve up, and if water squirts out, you have water 

Originally posted by Ghosthawk Much is made clear. Shore power not hooked up so switch in compartment is doing nothing. Ok. Switch inside which I assumed was for the electric is for the other. Since it is off, no hot water, no lighting attempt. Ok Learned something. Tommorow will go out with wife have her turn switch on while I observe. On the good news side, sounds like an easy fix. Also on good news side, this is the last real hurdle. We slept in the pod in our driveway last night. Good trial run. Bit cool out, but we were snug as could be. Have a few idea's on tweaking things. Need to get the mattress up, find a good 12 v source (thinking furnace) and get one of my 12 v plug in's with dual USB ports installed in that part of the pod.  Will probably install it close to the 110v plug in. There is a little shelf there just right for a cell phone on dock. Which would give us clock and a bit of light. Thanks all. John, brand new 189, so no bugs yet but thanks for the reminder to screeen everything.

Congratulations on getting your hot water.
