Long time lurker, first time poster. I've read lots of other threads with similar issues but nothing seems to match mine.
Got heavy rain a few days ago with some minor flooding. Since then, my pump trips the breaker after running for 3-5 seconds. I assumed the issue was caused by moisture in the motor or wiring. But the equipment has been sitting in the hot Arizona sun for a couple days and the problem continues.
I inspected the cord and removed the endcap of the motor and my layman eyes didn't see moisture or anything unusual. I also removed the cover from the run capacitor on top and it looked fine. The ground wire is still firmly attached. The motor and impeller appear to work as I can see water getting sucked from the leaf basket into the pump during those few seconds before it shuts off. The motor is hardwired to a breaker inside a control box. The controller and pool light work fine.
Unless its a big coincidence, I'm convinced the rain caused this. The equipment got VERY wet. I don't think the motor was submerged, but it's possible the flooding reached the bottom vents. But if the motor or starter capacitor got damaged, it wouldn't run at all, right? Could it be the run capacitor? An electrical issue that needs a pro? Or do I have to bite the bullet and buy a new motor?
Any advice appreciated!
