2 speed hot tub pump, Low speed works, Hi works for 2 seconds, then hums for a second, then cuts out.
I've had the tub for a couple months and the hi speed has always worked fine. This morning it started doing what i described. I'm semi knowledgeable about pumps and checked that the wire dedicated to the hi speed (and the one to low) isn't grounded out. If it was a bearing issue or something, i don't think the low speed would work. Any thoughts guys. Thanks.
