Display shows F16 and the unit may show erratic or impossible temperature values (e.g., -40°C or 99°C).

Safety first: Unplug the appliance before testing sensors or wiring.

F16 indicates that a temperature reading is outside the valid range expected by the control.

• 1. Identify which sensor is affected:
  • Compare displayed temperatures for each zone and ambient; the one showing extreme values is suspect.
• 2. Test the suspect sensor:
  • Access the sensor (cabinet, zone, or evaporator) and disconnect it.
  • Measure resistance at room temperature; if it reads near 0 Ω or OL, the sensor is faulty.
• 3. Inspect wiring:
  • Look for pinched or rubbed-through insulation causing shorts to the cabinet.
• 4. Replace with correct sensor:
  • Use only the Miele-specified NTC sensor for your model; mixing sensor types can cause F16.
• 5. If all sensors test correctly: The analog-to-digital converter on the main board may be defective; board replacement is required and should be done by a technician.
