Product review (5 stars): Genuine Part, my Whirlpool deserves it
This is the original OEM part.  Our washer kicked out f-33, 5-d (s-d?), and f-21... in that order.  This was the part needed.  I was a little surprised that the plastic foot came cracked on the new one, and I could complain but why?  I still had the old one and it was fine.  This is the small foot where the 2 screws go in from the bottom of the washer (visible in the picture).  Everything else was solid, so I just used the foot off the old one.  Used the rubber off the old one too.  You have to have someone pull the machine back while you unscrew from the bottom.  Took 30 minutes and back in business.

I wondered whether I should have gotten just the motor for about half the price.  But after getting this I'm glad I didn't get some off-brand motor and have to crank-off the motor from the plastic connector.  Money well spent.  Washing machine gets a lot of use and happy to have it running again.  Whirlpool Duet Sport bought at Costco model WFW8410SW01 manufactured in February 2008.
