There is a wavy type washer in the front bearing race that usually makes that noise when cold. It can be annoying but usually does not mean immediate failure. It is usually due to a bad grease job in manufacturing and is very typical on the AO Smith motors.

Mine was doing that for about a month or two till the pump seal failed. Good luck on that.

Probably a coincidence. Pump seals generally don't squeel. The area that squeels due to a bad grease pack is in the front bearing while the seal is ont he rear side of the motor.

poolboyz...did it sound like this??? (I hope this works!)

Mine started doing the same thing when the weather got a little cooler. Pentair says it's the bearings in the motor. Fortunately, mine is only 6 months old and they are sending me another. But I thought I'd see if this would help in pinning down your problem.

YESSSSSSSSSSSSS....that is the noise.....Thanks for the video...and thanks to everyone for the info...I will contact STARITE, but I dont think they will do anything.

If it's 2 years old, they may not. Pentair sent me a new one and it's working like a charm! Mine was only 6 months old though. I was told it was the bearings going bad. I sent the same video to them as well. Good luck!
