Miele Washing Machine Error Code F35 — Door Will Not Unlock
What this means
Error F35 indicates the door remains locked after a cycle has finished and the machine cannot disengage the lock. This can be caused by a faulty door lock actuator (the wax motor or bimetallic element that retracts the lock bolt), residual water in the drum keeping the safety interlock engaged, or a control board issue where the unlock signal is not being sent. The door may remain locked indefinitely.
Alternate codes: F 35
Step-by-step fix
4 stepsWait and retry
Some Miele models keep the door locked for several minutes after the cycle ends as a safety measure (especially after high-temperature washes). Wait at least 5 minutes after the cycle ends, then try opening the door again.
If water is visible in the drum through the door glass, the door will remain locked. Run a Drain/Spin cycle to clear the water.
Power-cycle the machine
Unplug the machine for 5 minutes, then plug it back in. The door lock may release when power is cut or restored. Try opening the door.
On some Miele models, the lock disengages mechanically when power is removed. On others, it requires power to unlock.
Use the manual door release
Many Miele washing machines have a manual door release — a small lever or pull-tab accessible behind the drain filter panel or at the bottom front of the machine. Pull it to manually disengage the door lock.
Check your owner's manual for the exact location of the emergency door release on your model.
Replace the door lock if it fails repeatedly
If the door lock consistently fails to release, the thermal actuator inside has degraded. Replace the door lock assembly following the same procedure as for F34.
A door lock that locks but will not unlock usually has a failed thermal actuator rather than a failed switch.
When to call a professional
If you cannot open the door using any method and laundry is trapped inside, a technician can access the lock from behind the drum.
