Miele F1045

Miele error code F1045 indicates: The unit stops during the drying cycle and displays an internal air overheat alert..

The primary root cause for Miele code F1045 is: The air temperature inside the tank has exceeded the safety threshold. The drying fan may be blocked, a clogged air duct, or the internal temperature sensor is faulty..

To resolve error code F1045: Unplug the appliance and allow it to cool completely. Make sure the tank filter is perfectly clean. Check that the drying fan spins freely and that the air ducts are clear. Test the temperature probe (NTC).

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Miele code F1045 persists, the physical component causing The air temperature inside the tank has exceeded the safety threshold. The drying fan may be blocked, a clogged air duct, or the internal temperature sensor is faulty. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
