Product review (5 stars): Easy replacement
Whirlpool Duet Sport (wfw8300sw00) front loading clothes washer got an F22 error message. I checked the pump (8540024 cl f) and found wear and damage to the propellor and armature. This replacement differs from the original in that the propeller blades are slightly smaller and the connector for the wires are different. See my photos. None of those differences matter. I ordered it Sunday night and received 5pm Tuesday using the 2 day shipping option. Installed and tested it in 25min. This is an A/C motor so you don't have to worry about which way you connect the wires. And on top of that the pump housing on my unit has a straight outlet so it works the same no matter which direction it rotates.
