Starting about 3 weeks ago, motor seems to be making louder noise and supposedly it is due to faulty bearing. It is A.O. Smith E-Plus switchless motor 1.5 HP with model # 38468600. Local pool supply store doesn't seem to carry it. Another place that carries it is distributor and doen't deal with consumer. Anyone has experience with this sort of problem and how much it would cost to replace/repair this motor? Is there any compatible motor to this one that would not require new plumbing? If it cost too much, I am even thinking about either emptying the pool or just adding **** load of borax/chlorine tabs and not use it for awhile. =( Thank you for any input in advance.
