Product review (4 stars): it's just a TERRIBLE TERRIBLE engineering fail of epic proportions
I hesitate to give this thing 4 stars.  Yes, it fit.  Yes, it fixed the problem.  But wow....it's just a TERRIBLE TERRIBLE engineering fail of epic proportions.  It's baffling to me what Whirlpool is able to pass off onto the public who, are forced to either become a semi-expert on their appliance or are essentially faced with a DIY project every year or a $200 repair visit.  I know a lot of people who just say 'we need a new dishwasher' which is so incredibly wasteful. The more disturbing thing is that this problem was exacerbated by the ridiculous plastic tab design on the rollers for the top tray which also break on a regular basis.  The broken plastic pieces eventually end up tangling with the chopper and assist in breaking it.  Why KitchenAid and some of these others simply don't issue an apology and offer a redesigned replacement is beyond me entirely.  They could go from creating a lifelong enemy to creating a lifelong friend.  You want to make a customer bitter?  Let them keep being forced to watch your product (which they use every day as a key tool in raising their kids) BREAK on a regular basis!

My case looks about like everyone else's. I included some pics of the disgustingness and the broken part.  Even if the thing is working properly, I don't see how you get away without having to change the chopper regularly - especially if you know what's going on down there. Trust me. You can't UN-SEE that nastiness.  It's gonna weigh on my conscience for sure.  My kid and I will survive...we aren't germ freaks.  But if the fiancee finds out I left that stuff down there to rot...she might have some words for me.
