Product review (3 stars): Compatible does not mean the same
I bought this part because whirlpool listed the part as a replacement part for my dishwasher only to find there is a slight gap as the curvature on the inside of my tub isn't the same as the model this is designed for.

It work, doesn't leak, but time will tell if having a different spacing (IE gap) will cause water/food collection and deterioration of the product.
