Strong unpleasant smell from inside the dishwasher, especially when opening the door after idle time.

Safety first: Wear gloves when cleaning internal components.

• Deep clean filters: Remove and scrub all filters with hot water and a brush.
• Clean tank and walls: Wipe down the interior surfaces with a non-abrasive cleaner suitable for stainless steel.
• Run cleaning cycle: Use a Winterhalter-approved machine cleaner and run a high-temperature cleaning program.
• Improve daily maintenance: Ensure filters are cleaned daily and the machine is drained and left slightly open overnight to ventilate.
