Nick6015 Posted October 17, 2021 Report Share Posted October 17, 2021 Hi All - As described, the main pump of my just-filled tub is cycling on and off upon initial start up. Something on the circuit board is also clicking. Any ideas? Thanks in advance! Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted October 17, 2021 Report Share Posted October 17, 2021 Are there any errors on the display? Does the display cycle on and off too? Unplug the topside control, does it still cycle? Quote Link to comment Share on other sites More sharing options...
Nick6015 Posted October 17, 2021 Author Report Share Posted October 17, 2021 Display behaves normally — displays Pr unless I abort Priming stage by pushing either temp button. That interrupts the on/off cycle for a moment, then it starts cycling again. I did some more troubleshooting… the cycling stops when I unplug the top side controls. With each unplug/plug in, the affected pump changes to the next speed: circ/low/high. Does that indicate top side needs to be replaced?
