How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow it to cool before handling the bowl.
- 1. Check for error messages: Note any codes or warnings on the display; they may indicate motor issues.
- 2. Inspect drive coupling: Remove the bowl and inspect the drive coupling on the base for wear or damage.
- 3. Check mixing knife: Inspect the mixing knife assembly for cracks or a loose hub. Replace if damaged.
- 4. Test with empty bowl: With an empty bowl, try a low-speed program. If the knife still does not turn and no loud noise is heard, the motor or motor driver may have failed.
- 5. Service required: Internal motor or board replacement must be done by a qualified technician.
