Washer has a persistent bad odor or moldy smell inside the drum

Safety first: Use only cleaning agents approved for washing machines and follow label instructions.

Steps to remove odors:

• Run a hot maintenance wash: Run an empty 90 °C cycle with a Siemens-approved descaler or washing machine cleaner.
• Clean door seal: Wipe the gasket folds with a cloth and mild detergent or diluted bleach solution. Remove any trapped debris.
• Clean detergent drawer: Remove and wash the drawer and housing to eliminate mold and residue.
• Leave door open: After each wash, leave the door and detergent drawer slightly open to allow drying and prevent mold growth.

When to call a technician: If odors persist and you suspect stagnant water in hidden areas, a technician can inspect internal hoses and sump for buildup.
