    Hot water Heater turns itself off
    I have an A. O. Smith Power Shot Power House GPSH 50 water heater.

    I noticed that I had no hot water. I found that the unit cycles off and on and then the vacation lit stays lit and the unit stays off.

    It is a gas hot water heater but does not use a flame.

    The unit is about 5 years old.
