Our 5er is new to us, we’re still learning a lot about it. Last weekend we were going to disinfect the fresh water system, I started with draining the water heater.
Lots of scale and hard water deposits inside. The anode was well used, also.
And the electric element was gone as well.
We got a wand to wash the white stuff out, and then filled the tank with half vinegar, half water solution and let it heat over night. That seemed to clean it up.
Replaced the element and anode rod, but the electric side is still not working. The thermostat is definitely bad, got a new one ordered, as well as the switch. Not sure yet if the switch is bad, but form what I gather from others, it seems they have a habit of going bad. If these things don’t fix it, I’ll have to dig further into it.
