Product review (1 stars): Not an exact match....NEW EDIT....DO NOT BUY!!!!!!!!!!
The Good: It fits my whirlpool Duet (GHW9250MWO) and works.  Received it quicker than expected.

The Bad: I was a little disappointed that there are only 3 fan blades on the propeller.  The original had 4, and one broke but still worked intermittently.  If one of these blades breaks, I suspect an immediate fail.  Time will tell.

The Ugly:  the picture on amazon is deceiving.  You only get the pump.  If you are looking for the catch basin, you need to order that separately.

EDIT: 4/15/2014:  Reduced to 1 star (zero if they let me) The part failed and started to melt almost causing a fire.  Unfortunately amazon doesn't let you upload photos anymore to show the damage.  The worst part is, that this company Appliance Parts US only offers a 30 day warranty.  They feel that if a part is going to fail, it will fail in the first 30 days.....ummmm yeah, if I was a laundry  mat doing 7 loads a day.  We have 2 people in the house and do 1 or 2 loads a week.  That's 4-8 loads in a 30 day period.  It's not an OEM part.  I had to go out and spend 2 times as much on a genuine part, and now it seems like I'm out the money for this part.  Lesson learned.  I spent 1.5 as much as I should have.
