Hot Water Heater - Electric mode

Purchased my 8317SS new last July. I never knew that I had the electric heat option on my water heater until last week when a friend showed me the hidden switch on his new unit located outside behind the access panel of the water heater.

When I arrived at a campground this past weekend and after hooking up and ensuring that the tank was full of water I took the cotter pin out and switched it in the on position. Never got any heat. I looked at the breaker inside and it was in the on position (flicked it off and back on just in case).

Any ideas on how to get it working? Another switch or procedure??

Thanks in advance -- Rob

The electric element may be burnt out...happens when you put power to the element with the water heater empty(I proved that out last fall). If you measure 120 volts across the element's terminals but don't get hot water, the element is toast.

What he said!
Also, if you have a little digital multi meter, you can
and measure across the heater terminals in Ohms setting.
If you get very high/infinite ohms it's burned out.

Since you removed the cotter pin yourself, I wonder if you don't
have voltage there somehow. Be sure and check for voltage (120v AC)
there first. Could be miss wired or something if it's never been used.

Good luck!
Let us know what you find out.

If the element is burned out your local big box store will have a replacement that will work. It's not difficult to replace just make sure the power is off and the tank is depressurized (open the T&P valve to make sure).

My Flagstaff has a switch on the wall by the bedroom door, where the A/C controls and tank level indicators are that says "water heater". When switching from gas to electric, you have a hidden power switch under the outside ventilation cover. Once that is on, you have to be sure your breaker in the WFCO power center is on, then I flip my rocker switch on the wall to the on position, and it lights up red. I then wait for about 10 seconds while the automatic system takes over. Once it's on, the light goes off. You now have hot water (after about 15 mins.) Hope this helps you! Randy
