How to Fix / Troubleshooting
Safety first: Stop the program immediately and unplug the appliance. Hot contents may splash.
- 1. Remove contents: Carefully empty the bowl into another container, checking for foreign objects (spoons, bones, pits).
- 2. Inspect mixing knife: With the bowl empty and cool, rotate the mixing knife by hand. If it feels rough, wobbly, or noisy, replace the knife assembly.
- 3. Check drive coupling: Inspect the drive coupling on the base for play or damage.
- 4. Test briefly with water: Fill the bowl with water and run at low speed. If loud mechanical noise persists, stop immediately.
- 5. Service for gearbox: Persistent grinding suggests internal gearbox damage, which requires professional repair.
