Brett and Cheri.

It took me about a year to figure out what the HW switch inside the RV was for. It was to turn on the gas/propane to heat the hot water tank (HWT). BUT, there is a 120V switch on the HWT accessed from outside the trailer which turns on the AC to heat the HWT instead of using propane. When connected to shore power, we turn the switch on to use AC to heat water. When dry camped, we turn on the switch inside the trailer to heat the HWT. Is my wife and I shower one after the other and we are connected to shore power, we also turn on the inside (gas/propane) switch to heat the water faster.

Maybe you have not found the AC switch on the HWT itself and it is in the "Off" position. Or maybe it is faulty. I replaced my switch last year.

It's another thing to check out. Good luck.
