Product review (5 stars): This thing does the trick - don't get ripped off by a repair guy
I got quoted about $300 for the guy to come out, "diagnose" the problem and then do the repair.  After reading a couple websites everyone said "REPLACE THE PUMP".  I took apart the out-of-warranty washer and lo and behold, there is really nothing else there except the tub, electrical board, bunch of hoses, and the pump.

Replaced the pump myself in a couple hours and saved about $250!!!
