Washer has a strong musty or moldy odor inside the drum

Safety first: Unplug the washer before cleaning internal parts.

• Run hot cleaning cycle: Run an empty 90°C cycle with a Bosch-approved washing machine cleaner or white vinegar (if allowed by manual).
• Clean gasket: Wipe the door seal folds with a cloth soaked in mild detergent or diluted bleach. Remove visible mold and residue.
• Clean detergent drawer: Remove the drawer and scrub away buildup. Clean the housing and dispenser jets.
• Leave door open: After each wash, leave the door and detergent drawer slightly open to allow drying and prevent mold growth.
