Strong bad smell from inside the dishwasher, especially when opening the door after idle periods.

Safety first: Wear gloves when cleaning internal parts.

• Deep clean filters: Remove and scrub all filters and strainers with hot water and detergent.
• Clean sump and walls: Wipe the tank, door seals, and sump area with a non-abrasive cleaner. Remove any trapped food or grease.
• Check drainage: Ensure the drain pump and hose are clear so no dirty water remains after cycles.
• Sanitizing cycle: Run an empty high-temperature cycle with an approved machine cleaner or sanitizer.
