Rxgofishing Posted May 14, 2022 Report Share Posted May 14, 2022 I have a 2013 Hotsprings Jetsetter tub with a single speed Wavemaster motor. Motor was whining so I replaced bearings and seal. Put it back together and now when I turn jets on the motor runs for 10 seconds and turns off. It will immediately turn back on again but only run for 10 seconds. No breakers tripping. No air locks because when pump is running it’s like a new pump circulating water very strongly. Seems like some kind of timer issue but I don’t see any timer settings anywhere on the control pad. It ran fine before I took it apart but it was whining. I must have done something wrong. Any thoughts? Thanks. Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted May 14, 2022 Report Share Posted May 14, 2022 Does it make a hard BUZZING noise before shutting off? Is it a 2 speed pump/motor? Was the wiring disconnected when you took it apart? Quote Link to comment Share on other sites More sharing options...
Rxgofishing Posted May 14, 2022 Author Report Share Posted May 14, 2022 No buzzing noise before shutting off. It’s a single speed motor. This tub also has a smaller motor which circulates water 24/7. Unit was wired just fine. I removed wires to replace parts but rewired exactly as it was when I took it apart. I just had to remove white and black wires from their terminals and remove nut holding ground wire. Is it possible to install bearings upside down??

Disconnect the pump from the board and test for constant power coming off the board when the pump is engaged on topside. Is the motor hot to the touch when it cuts out? Can you put your hand on it for more than a second? Seems like thermo cut out. Second/third look at wiring can't hurt. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 16, 2022 Report Share Posted May 16, 2022 I'd guess stuck or damaged start switch/centrifugal switch. The wishbone design is easily damaged when removing the rotor and can end up on the wrong side of the centrifugal switch when putting it back together. So it only runs on the start winding, which trips the thermal cutout in seconds. Won't ever get hot enough to feel it with your hand.

Rxgofishing Posted May 16, 2022 Author Report Share Posted May 16, 2022 That sounds like the problem! Because it doesn’t get hot before shutting off. I’ll have to take the motor back out and check. Thanks for your help. Quote Link to comment Share on other sites More sharing options...
