Patrick for Model Number DDT575SMF8ES I think a wine glass broke and a piece of glass(over time) has worn down the impeller on the drain pump. For a long time it made noise whenever draining during operation and during the last 2-3 minutes. Now it is quiet and most of the water drains out, none standing in the bottom of the machine but if not run daily it develops a horrible odor. I'm thinking i need to replace the drain motor assembly?
Answer Patrick, most dishwashers, if not run on a daily basis will start to put off an odor. There is always some water in the bottom of the sump assembly that will sour if not rinsed out. I would not replace the sump assembly just yet. Get a dishwasher tub cleaner and use it to freshen up the tub and sump. Using the dishwasher on a daily basis will also help. Read More...
