Product review (5 stars): Fits, works well!
Interestingly, Amazon's website could not find my Whirlpool model number to confirm it would fit my washer. I took a chance on it, and it did! The reason I bought this was for the little parts on top that help hold/separate silveware, and safely put knives point down without them damaging the bottom. Whirlpool model WDF330PAHS1 Type: 583-D
