Product review (1 stars): Not OEM, but knock-off junk.
This pump is advertised as "by Whirlpool" but it's a cheap Chinese aftermarket pump. I installed it in a pinch because I needed the washing machine to be up and running, and it leaked worse than the old genuine pump did after 20+ years of service. I had to put the old pump back in just to be able to use the machine. Even the cast pulley on this junk pump was so poorly machined and finished that it wobbled. This is the first time in around 40 years of fixing appliances that I've attempted to use a non-OEM part to address an issue and it will be the last. The seller is misrepresenting this item as OEM and doesn't respond to return requests.
