    I would trouble shoot the water heater to determine exactly what is wrong.
    It is possible for an element shorted to ground to heat constantly on 120 volts after thr t-stat shuts off.

    Default reset

    One or both of the elements is shorted out and causing temperature overrun. Do NOTHING until you know what needs fixing, or you will be replacing things that are not broken. In fact, a loose screw on the upper thermostat will cause the same problem.
