obpidaho Posted November 11, 2021 Report Share Posted November 11, 2021 I have an older Clearwater Spa that is flashing the ohh code and not turning on. I have looked at the circuit board and there is not reset button. I have turned the power off and left it overnight. When I turn the power back on it makes a few clicking sounds and then just starts flashing ohh again. None of the pumps or even lights will turn on. is there a way to do a hard reset?

RDspaguy Posted November 11, 2021 Report Share Posted November 11, 2021 You have a pump problem, stuck relay on the board, or a bad sensor. Post pics of circuit board, wiring diagram, and equipment. Do you have a multimeter? Quote Link to comment Share on other sites More sharing options...
