Product review (5 stars): Unlike others on Amazon, Has O-Ring... Has over 90  4 and 5 star reviews.
I am a person that looks at the 4 & 5  star reviews that are a " Verified Purchase" and if it's above 90%  I BUY IT...
A $35 solution to a $130 problem.
Before I ordered just this motor assembly I took the whole pump out to diagnose the problem and had a horrible time trying to get the hose clamps reinstalled properly. The old motor had the impeller buzzing/grinding/randomly not turning.
Old motor worked long enough for the SUDS error to show after the new motor/impeller showed up.  New motor showed up in "Prime Time" . Our old, but repaired Kenmore Elite HE3T is now still doing a fantastic job every day.  There is a lubricated  O-ring installed on this motor with the impeller.
