Strong musty or moldy odor coming from the dishwasher, especially when opened after being idle.

Safety first: Turn off power at the control; no electrical disassembly is required.

• Deep clean filter and sump: Remove and scrub the filter with hot, soapy water. Clean the sump area with a brush and hot water.
• Clean door gasket: Wipe the door gasket and folds with a cloth soaked in a mild bleach solution or dishwasher cleaner. Rinse thoroughly.
• Run cleaning cycles: Run an empty cycle with a dishwasher cleaner or a cup of white vinegar on the top rack, followed by a hot cycle with baking soda sprinkled on the bottom.
• Improve ventilation: Leave the door slightly ajar between uses to allow the interior to dry.
