CanadianSpaTech Posted April 14, 2021 Report Share Posted April 14, 2021 Could be a stuck button on the topside control. Disconnect the topside from the board and see if it will heat and run on automated. Might take a few hours to notice a heat increase without you being able to see it on the display. Does the spa have a second or Aux topside at the other side of the spa? If it does disconnect that first and try it. Do you have a multi meter and know how to use it? What country are you in? Post photos of the circuit board and the schematic on the inside cover so we can see what you have. 1 Quote Link to comment Share on other sites More sharing options...
