johnnoandy Posted February 5, 2022 Report Share Posted February 5, 2022 Hi all, A couple of days ago both the pumps on my tub stopped working and there's a tick tock sound coming from the control system that sounds like a car blinker. I've disconnected, reconnected all the electric going in and out as well as checked and replaced one fuse. Panel works, has PR on it indicating it's priming but nothing's happening. The PR stays. Not sure what to do next. Any suggestions? Specs/pics/vid below. Balboa VS spa control system VS510SZ. https://youtu.be/SuIZdGjeo4Q Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted February 6, 2022 Report Share Posted February 6, 2022 Check incoming voltage. Test sensors. If good, replace circuit board. Most likely the low voltage power supply on the board. Quote Link to comment Share on other sites More sharing options...
