I am redoing an electric water heater. New thermostats and new elements. The water keeps overheating. I replaced the upper thermostat twice and the High Temp reset keep blowing. The odd part is after the upper thermostat hits temp. and the lower element kicks in, I have 110V still going to the upper element and 220V going to the lower.
The upper element never shuts off until the reset blows from too hot of water?
Any ideas?
My next check is for a short in the element.
