Product review (4 stars): Duet washer replacement water pump
Pump works well and the fit is exact.  Replacement pump did not include large rubber "o" ring.  Had to reuse old one.  It worked fine.  If you remove the plastic drain assembly to ease installation, take note of the correct positioning of the "anti-vibration" rubber feet.  They need to be reinstalled positioned exactly as they were originally.  There are no instructions but overall it is pretty easy to install the new pump.
