Product review (5 stars): Fits my old KitchenAid dishwasher perfectly
The Whirlpool Dishwasher Spray Arm Retainer Nut fit my old KitchenAid dishwasher perfectly. Installing the nut was a snap too. Finally, the part arrived quickly after I ordered it from Amazon. My kids were delighted as they've been spoiled by having a dishwasher and were tiring of the old-fashioned method of washing dishes by hand. Poor kids! Smile!!!
