Miele Dishwasher Error Code F02
Temperature sensor open circuit
Common Causes
- 1NTC sensor disconnected
- 2Broken wiring
- 3Connector corrosion
Do not bypass the sensor to continue running — Miele heater elements can overheat without proper temperature feedback.
Step-by-Step Troubleshooting
- 1
Power off and unplug the dishwasher
- 2
Locate NTC sensor connector on the control board side
- 3
Check for loose or disconnected plug at both sensor and board ends
- 4
Measure sensor resistance (open circuit = infinite/OL reading)
- 5
Inspect wiring run for breaks, especially near hinges
Pro Diagnostic Tip
F02 is the open-circuit twin of F01: where F01 (short) reads near 0 ohms, F02 reads OL/infinite on the multimeter because the NTC path is broken. That difference matters for the fix — an open is far more often a disconnected or corroded connector, or a wire fractured where the loom flexes past the hinge, than a failed sensor bead. Reseat and inspect the connector at both the sensor and board ends before ordering the proprietary Miele NTC, since a good sensor with a broken plug reads identically.
