Answer to continue safely
Is it safe to keep using?
Yes. F06 does not pose a safety risk. You can use timed dry programs while troubleshooting the sensor. Sensor-based programs may not work correctly.
Can I reset the code?
Yes. Yes. Clean the sensor bars, reset, and test. If the bars were coated with residue, cleaning often resolves F06.
When to stop immediately?
Stop if you notice: F06 persists after cleaning sensors, The dryer overheats.
Symptoms You May Notice
Clothes still damp after cycle
The machine thinks items are dry before they actually are
Cycle runs too long
Without sensor data, the machine defaults to maximum drying time
Inconsistent drying results
Some loads come out perfectly dry, others are damp
F06 during the cycle
Appears when the sensor should be actively measuring
Possible Causes
Dirty Sensor Bars
The metal sensor bars inside the drum are coated with fabric softener residue or lint.
DIY PossibleFailed Sensor
The electronic sensor element has failed.
Requires ProfessionalWiring Fault
Loose or damaged connection to the sensor.
Requires ProfessionalSmall Load
Very small loads may not make sufficient contact with the sensor bars.
DIY PossibleBoard Input Fault
The sensor circuit on the PCB has failed.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the Sensor Bars
Locate the two metal bars inside the drum (usually near the lint filter opening). Wipe them with a cloth dampened with white vinegar to remove fabric softener buildup.
Do this monthly for optimal sensor performance.
-
2
Clean the Lint Filter
A clogged lint filter can affect humidity readings by restricting airflow.
Clean before every cycle.
-
3
Power Reset
Turn off at mains for 5 minutes.
The sensor may need to recalibrate.
-
4
Test with Normal Load
Run a normal-sized load (not too small, not overstuffed). Very small loads may not contact the sensor bars.
3-4 bath towels make a good test load.
-
5
Use Timed Dry as Workaround
If sensor programs are unreliable, use a timed program as a temporary workaround.
Timed programs do not depend on the humidity sensor.
When to Call a Professional
Contact a qualified Miele technician if:
- Sensor bars clean but F06 persists
- Sensor reads zero or maximum constantly
- Wiring damaged
- Under warranty
