Does anyone know what this switch is???

[HobieRV]

We have a 2003 Dolphin we bought used in 2006. There is a switch in the bathroom under the pump and light switch and above the GFI outlet. The is a side to side switch with an indicator light under. I have never had an interest or need to use it as I don't know what it is for. Thought it might be for the inverter but it doesn't seem to be. There is no documentation on this and the dealer just shrugged his shoulders. Anyone have this same "feature"???? See attached picture

Thanks

Since it is in the bathroom it is probably for the 110 volt electric heater element in the water heater.

Looks like switch for the "Flux Capaciator"

Possibly for the water heater?

Possibly installed by the previous owner?

Have always used the propane water heater with the switch at the management panel for levels and such.... Hmmm have to try it out, thanks

Odd that it isn't labeled if it is for the water heater. It almost looks out of place, like it might not have been original equipment. Might the previous owner have added something that you have not discovered yet?

my last fifth wheel had a light switch from the factory below the bathroom sink, for the electric on the hot water heater, but you also had a switch to throw at the water heater too.

If it is for electric water heater option:

The model number of a regular Atwood Water heater would have an "E" at the end (ie: G6A-8E) if it was ordered with electric heat option.

The model number of a XT style Atwood Water heater would have an "E" after the "G" (GE9 vs "G9) if it was ordered with electric heat option.

A suburban model number would end in a "E" or "EM" if it was ordered with electric heat option.

A PO could have installed a Hott-Rod aftermarket heating element: Hott Rod Electric Conversion 6 gallon Water Heaters Universal RV ..

Its common forpeople to add on an electric heating element, they would screw into the hole where either the drain plug or amode rod would go.

I have an 02 Dolphin with the same switch. It is for the electric element in the water heater.

Everyone forgot to add------ do not turn this switch without water in the heater. You will burn out the element in the heater. Don't ask how I know!!!!

Same one I have in our coach that controls the electric element for the water heater. Good advice to make sure the water heater is full before turning it on.

Yea, I know that too. When I winterize I always pull the plug on the heating element. It only takes a few seconds to burn it out. Like you said, don't ask how I know.
