Couple things right off the bat.
Which switch are you talking about?
There is one switch "inside" the camper with a red indicator light.
THAT switch is the propane-12volt DC heating system for the water heater. Turn it on and the red light comes on and propane is used by the 12 volt DC circuits to heat the water.
OUTSIDE the camper under the cover of the hot water heater is a small black rocker switch (that can have a "hairpin" safety pin through it) that powers the hot water heater with 120 Volts AC. It can be hard to find as it can be located behind pipes and wires. Mine is in the lower left hand corner.
These systems are independent and can be used separately or both at the same time.
If that rocker switch is "on" AND THERE IS WATER in the tank; it should work fine on AC even with the lighted switch inside the camper "off".
If it still won't heat on AC, check for AC power at the wall plug used by the hot water heater. If there is power there and the switch is on, it is possible the AC heating element has been burned out. If the rocker switch is "on" and the water has been drained out (like during winterizing) ANY shore power will burn out the element in very short order. Good news here is they are relatively cheap. Bad news is they can be a beeeach to change.
