Hot water heater not working on electric NEW Rig

[Sashamo]

We took our brand new 2015 Zinger 30RK out for the first time and we could not get the water to heat on electric. We checked bypass lines, all fine. The water heats just fine on the gas. This is our first gas/electric water heater. Is there something we are supposed to do besides flip the switch? Any help would be appreciated. We have the worst camping world in the country at our disposal and I would like to not have to involve them if there is a step we are missing.


Thanks,
