I left the hot water heater switch in the ELECTRIC ON position Over night after we got home. Question is will that hurt the unit? Or does it need shore power to heat electrically ? Gas switch was off only elec on.
Shouldn't have hurt a thing. The electric element in the water heater only works when the trailer is plugged into shore power.
Agree, won't hurt anything. However, I always turn off the inside breaker so that when I reconnect to power there is no chance I could burn up an element in case water somehow drained out of the tank.
To avoid this in the future, you might want to add a Lighted Switch for the 120V side of your water heater. I added one in a couple of hours, with minimal cost.
Here's a great thread by Willis, complete with pics, on installing the switch.
I was worried about this same thing but in a different context. My 4 yr old daughter likes to play with switches and with the hot water switches (propane and electric) within reach in the bathroom is their a cover anyone is using to prevent inquisitive fingers? I was thinking of installing a lock type thermostat cover over The water heater switches and slide out/ awning buttons to prevent any temptation. Any suggestions? Thanks!
