Product review (5 stars): suck out the water and pop this new food chopper ...
Fixed my Kenmore dishwasher.  Took me all of 10 minutes to remove the grates, suck out the water and pop this new food chopper blade in... much more cost effective than a new dishwasher.  If you find your water pressure in your dishwasher not reaching the top rack, Search for the youtube video and you will be able to easily replace this.
