Bosch Washer Maintenance Tips
- 1Clean the drain filter monthly to prevent blockages
- 2Run an empty hot cycle with washer cleaner monthly to prevent odor and mold
- 3Check and clean inlet hose filters every 6 months
- 4Leave the door open after each wash to allow the drum to dry
- 5Don't overload the drum — follow the manufacturer's capacity guidelines
- 6Inspect water supply hoses annually and replace every 5 years
- 7Level the machine properly to reduce vibration during spin cycles
