Product review (5 stars): Works with KitchenAid Model KUDE70FXSS
I compared this cap with the original burned cap and they are identical as far as I can tell.

KitchenAid did not confirm that this part number (W10077881) will fit my model, so I confirm it here.

BTW KitchedAid offered the whole assembly (part number W10195174) for $86. So if you call them and they say that for your dishwasher this is the part number, you can buy this cap instead for mere $25 with shipping :-(.
