Product review (5 stars): Fit IKEA Whirlpool Dishwasher
This fit an IKEA Whirlpool Dishwasher, model IUD9750WS4 type: 577-0. I had to get a new rinseaid cap after the original one fell out and melted on the heating element inside the dishwasher. I wasn't 100% sure this would fit, but the picture looked identical to the damaged cap, so I bought it. It was the exact same and fit perfectly! Very happy with the purchase, however I wish it was a little cheaper.
