Miele F1059

Miele error code F1059 indicates: The device reports an error and interrupts the current cycle, because the temperature inside the tank does not correspond to the expected values..

The primary root cause for Miele code F1059 is: The entire internal air temperature measurement system (including the NTC probe, its wiring and its connection to the electronic card) is defective..

To resolve error code F1059: Unplug the device from the mains. Check the entire internal air sensor circuit, from the sensor itself to its connection on the electronic board, including its wiring. Replace the item(s) identified as defective.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Miele code F1059 persists, the physical component causing The entire internal air temperature measurement system (including the NTC probe, its wiring and its connection to the electronic card) is defective. 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.
