Disposal starts and stops repeatedly; Miele interface shows F13 torque fluctuation error.

Safety first: Turn off power at the breaker before inspecting the grinding chamber.

• Inspect grinding components: Look for loose or damaged impellers and ensure the grinding plate is secure. Any broken parts require replacement.
• Remove fibrous waste: Clear fibrous materials (celery, corn husks, onion skins) that can wrap and release repeatedly, causing torque spikes.
• Manual rotation: Use the bottom hex socket or jam wrench to rotate the motor shaft through several full turns, confirming smooth movement.
• Control issue: If mechanical parts are sound but F13 persists, the torque sensing circuitry on the control PCB may be defective and should be serviced.
