Hot water heater not working on electric

Seeking advice:

Last two trips our hot water heater will not work when on electric setting. Will work when turned to gas.
Any suggestions are appreciated.

Thank you in advance!

I had that happen once on a Bounder and one of the wires worked it’s way off of the connector. Was not visible until I removed the plastic covering. Just a suggestion.

There's usually a house style Off/On switch that powers the heater. Check that didn't get accidentally flipped (I mention it because mine was on the bed stand and that's exactly what I did several times while making the bed over the first year I owned my first RV). That switch is also a good place to check that there's power before and after the switch.

In my 2nd RV, it was up over the power control center in the hallway. It was unmarked and had a twin which turned out to be the On/Off for the block heater. That one also was a mystery for a while until I guessed that it HAD to be the water heater element. I laugh at myself now, but back then, I didn't have the time while traveling to figure out what it was or where my water heater element power was coming from.

And of course, there will be a Circuit Breaker involved, along with, in some RVs a CGFI, so if you have several outlets near water that are out, or an odd one that's by itself, be sure to get that checked or test it yourself.

Brand?Model ?

Atwood/Dometic uses common DC for controls
*On/Off, t-stats, thermal fuse
AC not working could be circuit board issue, lack of DC to the Relay or bad AC element
*Ac wires on DC Relay can me burnt

Suburban uses separate controls for AC & Gas
120VAC from circuit breaker to On/Off to set to t-stats to element
Could be tripped circuit breaker, bad On/Off switch, tripped High Temp T-stat (manual reset---Push to Reset above gas valve/Left side), bad element
*AC Wiring in the AC Junction Box on side of WH Tank could be loose/bad
