Dealing with a smelly dishwasher can be frustrating! A simple solution is to run a cycle with white vinegar. Just place a cup of it in the top rack. Baking soda can also help; sprinkle some on the bottom and run a short, hot cycle. Have you noticed any particular cause for the odor, like trapped food? It's good to clean the filter regularly too. How long has this been an issue for you? I'd love to hear more!
