Cleaned the hot tub. Got a new tool at Harbor freight that is a submersible pump, empties our 800 gallon tub in five minutes. Takes about two hours to refill. When I turned it back on, no power light. Checked the circuit, power going in, but no pump. Called the service tech and got an appointment for next Tuesday. Augh! Went back out to close it up and it was working.... Must be Gremlins.
