Disposal does not start; Miele interface shows F09 door/interlock or safety cover error (for models with integrated safety cover or sink stopper detection).

Safety first: Ensure power is off before adjusting any safety components.

• Check baffle/stopper position: Confirm the Miele sink baffle or stopper is correctly installed and fully seated as per the user manual. Some models will not run without it.
• Clean sensor area: Wipe away food residue or scale around the safety sensor area that may prevent proper detection.
• Inspect interlock switch: Under the sink, locate the safety switch or sensor housing. Check for loose mounting screws or obvious damage.
• Test operation: Restore power and try starting the unit with the baffle correctly in place. If F09 persists, the safety sensor or wiring may be defective and should be serviced professionally.
