E02 Water temperature exceeded high limit Switch the two house circuit breakers dedicated for the water heater to OFF and then press the reset button located behind the control panel on the water heater. Flip the house circuit breakers to the ON position. If error returns, call a service technician for assistance.
In order to reset, you may have to run the hot water in your house until it runs cool, this is a very important step to actually reset the hot water heater when clearing the code. This step is missed by everyone I have seen responding to this question.
