Product review (5 stars): fixed Whirlpool wed9500tw0  steam
Had to cut the 'lone' pin for fitment but the washer is fixed; no more sud or F35 codes, but the 'proper' part cost twice as much.  Curious, that the colors of this two-piece part is reversed from the original one fitted.

Huge thanks to those who went before to allow my success with an otherwise good machine.  I am a bit disappointed that Whirlpool/Maytag doesn't redress this faulty part, tarnishing their reputation.
