: I was reading that Dwight Mac Thurston had this same problem and I was wondering if this is a common problem with State Water Heaters and what he did to fix the problem?It not an uncommon occurance,for any brand of electric water heater, to trip the ECO. This can be caused by a few things: Loose wiring connections, element burn-out, thermostat not installed snug against heater, or most commonly inoperative thermostat. Test the elements and make sure they are opperating then try replacing the thermostats.
