How to Fix / Troubleshooting
Safety first: Remove the battery immediately if you hear grinding or scraping. Do not continue to run the vacuum.
- 1. Isolate the noise: Remove the floorhead and wand, then briefly run the motor unit alone. If the noise persists, it is internal to the motor.
- 2. Check for external obstructions: Inspect the air inlet and outlet for foreign objects.
- 3. Do not open the motor housing: The motor assembly is not user-serviceable.
- 4. Arrange professional repair: Contact Miele service to replace the motor unit. Continued use can lead to complete failure or overheating.
