Cnthinkoname Posted May 14, 2017 Report Share Posted May 14, 2017 Hey Everyone, Approximately two months ago I replaced both pumps in my spa. One began to make a loud "ringing" sound which sounds like an old school fire alarm. After some digging online, I found that I could be due to incorrect wiring, however it seems to follow the diagram. The ringing did not happen when the pump was installed, and I just noticed it when I had the skirt off to replace some rotten plywood backing. Here is a video showing both the sound and the wiring along with the diagram. Any ideas would be highly appreciated! Thanks! Quote Link to comment Share on other sites More sharing options...
dg98adams Posted May 14, 2017 Report Share Posted May 14, 2017 Are you sure it's the motor? Can you put a screw driver on it and listen to the "ringing"? Quote Link to comment Share on other sites More sharing options...

The sound starts/stops with pump 2 being turned on and off. I made sure there is nothing touching the motor/wet end and even took it out of the mount to isolate that.

Jersey Hot Tub Repair Posted May 15, 2017 Report Share Posted May 15, 2017 Sounds like the pump vibrating in it's motor mount. Make sure your screws holding it in are tight. Are their any loose screws in the pump? Perhaps the bonding wire, the through bolts or the screws on the electric cover plate? Dave Quote Link to comment Share on other sites More sharing options...
dg98adams Posted May 16, 2017 Report Share Posted May 16, 2017 The long screws that hold the wet end on.... are they tight? also the impeller on the shaft.... could it be cracked or is the wet end new too? Quote Link to comment Share on other sites More sharing options...
Muny4nothn Posted April 17, 2018 Report Share Posted April 17, 2018 I am have my the same problem. It doesn’t ring at first. Usually after running on High for about 10 min. Is it maybe an overheating alarm? Quote Link to comment Share on other sites More sharing options...
Cnthinkoname Posted April 19, 2018 Author Report Share Posted April 19, 2018 My wiring ended up being backwards in the control box. Fixed the wiring and had to replace the motor. Quote Link to comment Share on other sites More sharing options...
