Great video
I checked my resistance on the new heating element I installed at it measure 10.3 just lime your video
I still don't have hot water on the electric side. Any help would be appreciated

[@HowToRV]

It is possible the the reset button on the water heater needs to be triggeres. Look for the Black button that has a rubber cover. I would love to hear what you found to be the issue when resolved.

Im a subscriber, On my RV Electric heater element... My ohms test is 10.4 so element is good how do I TEST to see if the element is getting shore power?? , do you have a video on that? I live way out and no techs will come 5 hours. I am pretty handy and have do most things for myself. All the breakers and fuses are good. Dometic Heater WH-6GEA works on propane no problem at all. Just not shore power. I did put the volt tester leads to the heater element black and white wires but no power shows up on the AC side of the meter. I had instock spare stuff and one was the control board, installed that but it is doing exactly the same thing with a brand new control board (atwood part number 91365 ) ...Not sure where to go from here. Your help would be appreciated. Thanks

I would go to where the water heater is either plugged in or hardwired and check to see if there is shore power available. If it is, make sure that there isn’t an on of switch, button or panel somewhere in your RV. Outside that, the controller may be suspect although you swapped it out already. Sometimes the controller is bad from brand new. I do not have a lot of experience with Atwood but there isn’t many parts between the power lug and water heating element. Oh and check to see if there is a temp sensor somewhere, I fought this to be a problem since the propane side is working. Worth a check though.

Does it matter which lead goes to correct screw
White or black
My casita camper doesn't show negative or positive only a black and white lead

[@HowToRV]

It should not matter as long as the wires are disconnected.

How to checkout the propane water heater

[@HowToRV]

I understand and have made other videos that may help.

[@francoislapalme8015]

Does the water tank have to be empty?

[@HowToRV]

No it doesn’t. Only needs to be empty to replace if needed.
