I Have a 2006 State Select Hot Water Heater and the hot water is scalding hot, and my teperature settings I have 2 are set on low. There is a red reset button on the top thermostat that keeps poping so I have to reset it but the water still gets scalding hot. Is it the thermostat ? Or the heating elements ? The MODEL # ES652DORTGW. Hope you can help me thanks CRAIG.
