Washer emits a bad smell (musty or sewer-like) from the drum or detergent drawer.

Safety first: Unplug the washer before cleaning internal parts.

Step-by-step cleaning:

• Run a maintenance wash: Run an empty 90°C cycle with a washing machine cleaner or a cup of white vinegar (check manual for compatibility).
• Clean gasket and drawer: Wipe the door gasket folds with a cloth and mild detergent. Remove and scrub the detergent drawer and housing.
• Check drain filter: Clean the pump filter to remove trapped lint and sludge.
• Leave door open: After each wash, leave the door and drawer slightly open to allow drying and prevent mold.
