What should I do if there is a bad odor coming from the dishwasher?

Remove and clean the filters according to the 'Check/Clean the Filter System' section, and clean the door gasket and door seal with a damp cloth to remove food particles. If odor persists, run a Normal/Regular cycle, interrupt it, place an 8 oz. cup of distilled white vinegar on the top rack, and finish the cycle. Also run a Rinse & Hold cycle if dishes will sit in the dishwasher before being washed. (Page 24)
