Dishwasher interior and dishes smell bad, with persistent odors even after cycles.

Safety first: No electrical work is required; keep the appliance unplugged only if working near wiring.

• Deep clean filters and sump: Remove all filters and scrub them with hot soapy water. Clean the sump area thoroughly, removing any trapped food.
• Clean door seals: Wipe the door gasket and around the door edges with a mild disinfectant solution.
• Run cleaning cycle: Run an empty hot program with a dishwasher cleaner or a cup of white vinegar on the top rack.
• Improve usage habits: Scrape plates before loading, run regular hot cycles, and leave the door slightly ajar after use to allow drying and ventilation.
