Possible Causes

Partially jammed grinding chamber, Shorted motor windings, Incorrect supply voltage, Defective current sensor on control board

How to Fix / Troubleshooting

Safety warning: Disconnect power at the breaker before inspecting the unit.

  • Check for partial jam: Look into the chamber and remove any large or dense items (bones, fruit pits, utensils). Ensure the turntable rotates freely by hand or with the supplied wrench.
  • Verify supply voltage: Have a qualified person measure voltage at the terminal block to ensure it matches the rating on the Miele nameplate (e.g., 120 V or 230 V). Incorrect voltage can cause overcurrent.
  • Inspect for overheating: A burnt smell or discoloration at the motor housing suggests winding damage; do not continue to reset and run the unit.
  • Control board sensor: If the motor spins freely and voltage is correct but F04 persists, the current sensing circuit on the control PCB may be faulty and requires professional replacement.
