Its got a new filter,pumps still working but water not heating. I unplugged the Tub and pushed the reset on the circuit board ,no help, I didn't clear its program did I?

cranbiz Posted September 30, 2021 Report Share Posted September 30, 2021 When the tub is calling for heat, D20 should be on. Do you get 120V on the heater terminals at all? @castletoniaAny ideas? Quote Link to comment Share on other sites More sharing options...
Dale P Posted September 30, 2021 Author Report Share Posted September 30, 2021 No 120V on heater terminals at all Quote Link to comment Share on other sites More sharing options...
castletonia Posted September 30, 2021 Report Share Posted September 30, 2021 I would be thinking either pressure switch or circuit board and leaning towards the pressure switch if everything else works. Quote Link to comment Share on other sites More sharing options...
Dale P Posted September 30, 2021 Author Report Share Posted September 30, 2021 Is the pressure switch just and open or closed switch? It is an open circuit when pump is off and on now. Quote Link to comment Share on other sites More sharing options...
