Monogram dishwasher has a persistent musty or moldy odor inside the tub.

Safety: Use gloves when handling cleaning chemicals.

• Deep clean filters and sump: Remove all filters and scrub with hot soapy water. Clean the sump area thoroughly.
• Run cleaning cycle: Run an empty cycle with a dishwasher cleaner or a cup of white vinegar on the top rack.
• Check drain and vent: Ensure the unit drains fully and the vent is not blocked.
• Leave door ajar: After cycles, leave the door slightly open to allow drying and prevent odor buildup.

Repeat cleaning as needed. Persistent odors may require inspection of the drain hose and air gap for trapped debris.
