|In response to Re: Hot Water Heater Overheating?|
The two elements are set for non-simultaneous operation. The upper one operates when you are about to run out of hot water to try to heat it as it is leaving the tank. If the lower one is operating at 240v continuously, then the thermostat is defetive. If only one leg is operating then the element is bad and may have also damaged the thermostat.
: I have an 80 gal electric hot water heater that services only my master bath. About 3 days ago, we noticed that the water coming out of the faucet was suddenly VERY hot. Then this morning, no hot water. This evening I took one side off the wooden box that encloses the unit and hit the reset button just above the top thermostat. Walla, hot water. But ... according to my electrical tester, the bottom thermostat is always staying on.
: My questions are:
: 2) I think I will disconnect the bottom element as a temporary solution. Any problem with this?
: 3) Can I buy and install a new thermostat myself? Any advice?
: 4) The water heater is about 6 years old. I am pretty sure that this same thermostat was replaced about 4 years ago. Any ideas on why this problem would repeat?
: Thanks for your help.
