Error code F33
Appliance Dishwasher
Quick answer

F33 on a Miele dishwasher means the door lock does not open. Models with automatic opening can try opening the door manually.

Model compatibility

Miele reuses codes across series and model years, so F33 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Door does not open automatically or door locking pins do not retract; possible technical fault.

Two readings of F33

  • Door lock does not open: technical fault, book a repair appointment.
  • Automatic-opening models (en-GB manual): the door fails to open itself or the locking pins stay in.

Try

  1. Open the door manually.
  2. Switch the dishwasher on again.
  3. If F33 returns, call Miele.

Look-alikes

  • F36: defective door lock switch
  • F26: boiling protection
