Washer-dryer has a persistent musty or moldy odor inside the drum

Safety first: Unplug the appliance before cleaning internal parts.

Step-by-step cleaning:

• Clean gasket: Wipe the door gasket thoroughly with a cloth and a mild bleach solution or washer cleaner, paying attention to folds.
• Run maintenance wash: Run an empty 60–90°C cycle with a washing machine cleaner or white vinegar (check Balay recommendations) to remove internal residues.
• Clean drawer and filter: Remove and clean the detergent drawer and pump filter to eliminate trapped residues.
• Ventilation: After each use, leave the door and drawer slightly open to allow drying and prevent mold growth.
