Product review (3 stars): Unnecessary part?
Original part and I'm sure it will fit perfect, however I'm currently running my d/w without it due to the old chopper falling apart and hesitant to install it. The reason is it is just a such poor design (boo Whirlpool) that will inevitably clog rather sooner than later. It is not much of a chopper and solid pieces such as small seeds will be trapped by and stuck in the screen forever until you take it out and punch them out with a toothpick or the like. It is not super-difficult to remove it and put back in but it is not a 5-minute job either. So the choice is yours whether to rinse the dishes before putting them into the d/w or clean the chopper screen every 6-8 months. Decisions, decisions...
