There have been numerous reported issues in the Relay box mounted on the back corner of the Hot Water Heater. The switch inside the RW that's labeled for the Electric Hot Water supplies only 12VDC to the relay box on the heater. That relay is what connects the 120VAC to the heater. Mfrs have been doing a poor job of connecting the leads using wire nuts. I had a poor connection that melted the wire nut and then shorted to ground tripping the heater's breaker. Something to look into.
