My coach has the 431 AquaHot with the 110VAC & 220VAC heating elements.
My Aquahot overheated twice in two days and caused the circuit breaker on the 220 degree VAC dual high limit thermostat to trip. After resetting the circuit breaker the second time my 220V heating element was no longer working-my voltage meters only showed a 10-12 amp draw on only one leg. The 220 degree VAC dual high limit thermostat is located behind the 4" x 6" stainless steel cover on the left side of the tank as you face the tank.
A call to Rudy Leggett-Mr AquaHot-helped me understand the electric flow from the on/off switch to the heating elements. Using a volt meter I found 240 volts flowing from the AquaHot relay to the 220 degree VAC dual high limit thermostat. There was only 120 volts coming out of one side of the 220 degree VAC dual high limit thermostat. Therefore only the 120V heating element was working.
Replaced the 220 degree VAC dual high limit thermostat and both heating elements are now working!

A special thanks to Rudy for his help!!!! For all Newell owners I would encourage you to attend the No Rally Rally at Sun Resorts in Orange Beach, AL. At the rally you can meet Rudy which will become an important asset for keeping your AquaHot running. I have owned my Newell for 14 years and with Rudy's help I have been able to keep my unit running doing the work myself.
