Product review (5 stars): Fantastic replacement for my whirlpool duet washer
I bought this to replace the pump in my whirlpool duet as I got f-21 drain errors constantly. Item arrived a little late due to a major snowstorm. Comparing the two, this appears to have been updated with modifications. A new screw cap for the trap which seams tougher than the original. Installation was quick and easy. Washer is running better than ever now with no more error codes!
