Product review (3 stars): Dishwasher Part # w10239405 vs. #w10237169 ??
I have a KitchenAid dishwasher too.
I called the KitchenAid parts line (1-877-486-2371) and, based on my exact model number, they told me to order part # w10239405. BUT, based on these reviews, instead I bought #w10237169. Bad move--it did NOT fit. I am returning it and will replace it with # w10239405.
My advice? Call the KitchenAid parts line, give your exact dishwasher model number, and order whichever part they recommend. BTW, once you get the correct part number, it'll cost less if you buy it here on Amazon.
