Any ideas on how to repair the switch other than replace the unit, which I really do not want to do since after a flush and new anode rod it is working GREAT.
These little black switches are bad about getting stuck. I keep an extra one in my RV just for when it happens. My local RV dealer has them on his front counter for about $10.
As long as the breaker to the outlet that the water heater is plugged into is off (or if is direct wired the same thing), then you're good to go...and won't burn up the element....since no 120 volt power is going to the element.
You can work with it to see if you can get it to work loose, but if not replacement is simple. You just have to release the tabs holding it in and unplug the old wires. Installation is putting the wires back on the terminals and snapping the switch back into the housing. The burner tube that's in the way, is the hardest part.
