Product review (1 stars): Part vendor OK, OEM part is a piece of junk. Don't buy KitchenAid dishwashers!!!
Replaced this failed piece (actually 2--both sides) in an 18 month old KitchenAid dishwasher. This piece will undoubtedly fail again. It is made with plastic that cannot withstand heat and moisture in dishwasher, so it gets brittle and breaks. Totally flawed engineering design. It is a piece of junk, and KitchenAid/Whirlpool will not stand behind it. I will not buy a KitchenAid dishwasher again. The  vendor selling part did fine, prompt shipping.
