its the upper thermostat...

electrical water heater only got 4 replacement parts, upper and lower heating elements, and upper and lower thermostats..

most likely the upper thermostat is the problem, just recalling from my memory, there is a 5 wire and a 6 wire version ( I need to check and make sure again), you need to find the exact match, lowes sells both. and make sure wiring is correct.

of the these 4 parts, usually the lower element will go first because the sediments build up inside, you need to drain the water heater once every 2 years.
