Product review (5 stars): Also works on Whirlpool Duet front-load washer.
I was a little bit hesitant to order this to fix our washer. But since the item description included the OEM P/N AP3953640, I just went ahead and ordered.
I placed the order on Saturday night. Got it on Wednesday, from FL to CA, with the cheapest shipping option ($5.49). Installed that night and after 10 minutes the washer was up an running again. That was fast.
Removal/installation was pretty simple. But as other reviewers have mentioned, you better be gentle with that O ring or you'll be in -unnecessary- trouble.
