Product review (1 stars): Too large for advertised Whirlpool Duet washing machine
This pump absolutely works for Whirlpool Duet Washer Model WFW9550WW10, however unfortunately it is slightly too large (too tall by nearly 3/4 of an inch) for the guts of the machine causing unnecessary rattling of the inside parts of the machine along with the pump being very hot upon removal. I have attached a picture to show this. The part on the left is the original Whirlpool part, the one on the right is the Supco replacement pump. As you can see, it is taller than the original part. I would recommend just spending the extra money on the Whirlpool part. It's not worth replacing a $1000 washing machine with an imperfect fitting part.
