Alarm beeps frequently and temperature alarm icon appears, even though the door is closed and temperature seems normal.

Safety first: Unplug the unit before testing switches or sensors.

• 1. Acknowledge alarm:
  • Press the alarm or OK button to silence it and see if it returns.
• 2. Check door switch:
  • Ensure the door contact switch operates reliably and is not loose.
• 3. Stabilize load:
  • If many warm bottles were recently added, allow 24 hours for temperature to stabilize.
• 4. Inspect sensor connections:
  • Reseat connectors for cabinet and zone sensors on the control board.
• 5. If alarms persist without real temperature issues: The control board may be overly sensitive or faulty; consult a Miele technician for diagnosis and possible board replacement.
