On my coach (a later 2007 model) the water heater switch was an unmarked residential looking toggle light switch and red indicator lamp on a single plate and mounted in the same hall cabinet as the tank level indicators... I have heard of this switch being in a sink cabinet on some gas engined coaches.

I have no specific suggestions where you might find yours, and of course there may be a circuit breaker for this 110 volt circuit as well so check for that also.

For the electronic ignition gas system for the water heater, there should be a switch and small LED indicator in the area where your 12 volt auxiliary water pump control is located. There may also be a small rocker switch on the heater itself to turn off the gas ignition there.

On my 95 Scenic Cruiser, the Water heater power seems to come from the panel on my range hood, when it quit working, I lost my water pump and heater level sensors and vent fan. I replaced the fuse in 2009 so I am not sure if it was in my Battery Control Center or the Fuse Panel/Circuit Breaker Panel on my Bed Platform. At least, it gives you two places to look.

On our 2001 Yellowstone bus there are a few places to check. By the sink you should see a residential looking light switch and the toggle is red plastic. Flick that up/down to see if it illuminates. Next check the water heater itself as mine has an on/off switch on it. But make sure you look for the breaker first... our panel is under the bed and the water heater is on it's own circuit.
