I've had more issues with this dishwasher due to its design flaws than any other appliance I've owned.

Upon my wife complaining that it wasn't cleaning well I found that the chopper had broken off from the shaft.  No idea why, I've seen others say that it is a design flaw and that over time it hits the housing enough to break the plastic.  I can't say why it broke as I saw nothing in the housing that would have caused it to break off.
