Pool Pump motor squeaks at start up and when stopping

Might check the cooling fan. They can sometimes rub the grill of the pump. Not an issue for performance or longevity.

Take care. Thanks for posting.
 
It might be the bearings or the shaft seal. Look under the pump for a leak.

I suspect that it’s probably the seal. If it’s not leaking, it’s probably best to leave it.

It might resolve of its own accord.

If you do change the seal, get a good one such as the U. S.Seal PS-3865R or PS-1905.
