Product review (5 stars): OEM, works.  Great price.
Washer drain pump must have been malfunctioning for a long time but not appreciated as it still drained, but slowly.  The pump vane apparently gets loose on the shaft, so it seems to pump, but is not able to lift the water all the way to the drain pipe.  The washer was giving a drain error, so It left me puzzled for a while until I decided to just believe the machine, ordered and put the new one in; then the difference was obvious.  Plus it was a lot quieter.
The whirlpool/Sears HE3t is a poor design; there is a filter/drain point to catch things that get out of pockets and into the water, but there is nothing to stop them getting caught on and damaging the pump vanes (in my case it was the remains of a ballpoint pen which had been inadvertently washed...).  Also, unlike a plumbing P-trap, or lint filter which can be accessed (as you might think you would with this), it is hidden behind the lower front panel which requires a torx screwdriver to remove (if you know to do so).  I guess it allows them to keep selling parts.
