Water heater not working.

Trying to get the trailer ready for its first trip, making sure everything is working. Everything is working, except the water heater. Its a gas/electric unit, but isn't functioning on either. The gas appliances are working the electric ones are to.
Trailer has been plugged in to shore power since bringing it home, but I've had the unit switched off at the switch inside the WH service panel on the outside, and it was drained during the winter. Not sure what to check to try and get it going before Sunday. 1st pic is the WH switch on LP gas, 2nd is when I try and run off power, 3d is inside the service panel showing the switch that I turned off after draining it for the winter. Lots of oxidation on all the galvanized items, neither the dealer or I live near the coast, asked the dealer about this, they said thats from where it was manufactured???

Well Google to the rescue. Turns out that when I flip the switch that lights up the DSI fault light, it stays on until the water heater lights. I switched it on and the it lit with in 30 seconds.
Looks like all systems are operational.
