Product review (5 stars): HE3t Water Pump
Works perfectly!  Be sure to save your old "o-ring".  They are correct; it only took 3 screws to replace old pump.  Customer service was wonderful, as they answered my questions and pointed me toward the correct pump for my model.  The only concern that I have is that a ceramic piece on top of the pump gets very hot after wash loads, but as that has not caused any issues I think it is simply the motor friction and is expected.  When my washer failed I was worried that I'd have to purchase a new washer (I didn't want to spend countless $$$ getting a repair person out and finding a more costly problem) so I tried this option to complete satisfaction!
