Kumar October 06, 2013 for Model Number du900pcdq5 Last week there was some kind of smell in the dishwasher when I started the dishwasher. So I stopped and checked and found some kind of rubbery stuff. I removed the impeller and found the check balls missing and that is when I found out the check ball has melted.
