Dishwasher has a bad odor; smells like mildew or rotten food even when empty.

Safety: Use gloves when cleaning dirty filters and sumps.

• Deep clean filter and sump: Remove the Samsung filter and wash with hot soapy water. Clean the sump area with a brush to remove slime and debris.
• Clean door gasket: Wipe the door seal and bottom lip with a mild bleach solution or dishwasher cleaner to remove mold.
• Run cleaning cycle: Run an empty cycle with a dishwasher cleaner or a cup of white vinegar on the top rack.
• Improve drainage: Ensure the drain hose has a proper high loop and no low spots where water can stagnate.
