RDspaguy Posted March 20, 2020 Report Share Posted March 20, 2020 This is your owners manual. https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.sundancespas.com/media/3475/880-series_english.pdf&ved=2ahUKEwi4tIPwyanoAhUNK80KHb32BiwQFjABegQIBBAC&usg=AOvVaw0VMxhasFXQgDCQx6Jov0Ys Are there any error codes on the topside? Is the screen blanking out and restarting also? What do you mean by "tries to start"?Is it making a noise? If so, what kind of noise? Will it move water or just make a noise? This could be a pump issue or a control power issue. Do you have an electrical tester and understand how to use it? Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted March 21, 2020 Report Share Posted March 21, 2020 Good. When it "tries to kick in", does it sound strange, make a buzzing or humming noise, or sound unusually quiet? Does it spurt a little water out of the jets before it stops? Follow the wire from the pump to the control box. If I remember correctly, there will be a strain relief at the box then wires go to screw terminals on circuit board. With power off, remove red and black pump wires from terminals on board. Turn on power and test voltage going to the pump terminals on the board, first low, then high with your other test lead on the white pump wire terminal. Use the topside button to test both terminals during both pump speeds. Verify that power output to the pump is constant 240vac and that only one of the red and black wire terminals has power at a time. One should be hot for low speed, the other for high. If power is good, we look at the pump, if not, the controls. Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted March 22, 2020 Report Share Posted March 22, 2020 '94? The good old days. I worked for a sundance dealer early in my career, '98-'99 I think. Do you know what control system you have? I might have to dredge up some old memories, and tech books, for this one. Quote Link to comment Share on other sites More sharing options...
