Miele Dishwasher Error Code F32 — Door Lock / Door Switch Fault
What this means
Error F32 on Miele dishwashers indicates a problem with the door lock assembly or door micro-switch. The dishwasher requires a confirmed door-closed signal before starting any cycle. If the door switch does not close or the lock mechanism fails to engage, the machine displays F32. Causes include a worn or broken door latch, a faulty micro-switch, misalignment of the door, or loose wiring to the door switch.
Alternate codes: F 32
Step-by-step fix
4 stepsCheck the door closure
Open and close the door firmly, ensuring it clicks into the latch securely. Check if anything is obstructing the door (protruding dish, utensil, or shifted rack). Push the upper and lower racks fully in and try again.
Overloaded racks can prevent the door from closing fully, especially if tall items protrude above the rack edges.
Inspect the door latch and strike plate
Examine the latch hook on the door and the strike plate on the tub frame. Look for wear, cracks, or deformation. If the latch does not snap firmly into the strike, the switch will not activate.
On older Miele models, the plastic door latch can become brittle and crack. It is an inexpensive part to replace.
Test the door micro-switch
Unplug the dishwasher. Access the door switch (usually behind the inner door panel, near the latch). Disconnect the switch and test for continuity with a multimeter — it should show continuity when pressed (door closed) and open when released.
Some Miele models have two switches — one for the door-closed signal and one for the door-open safety. Test both.
Check the wiring harness
Inspect the wires running from the door switch through the hinge area to the control board. The constant opening and closing of the door can wear through wire insulation at the hinge point. Look for broken or chafed wires.
Flex the door open and closed slowly while watching the wires at the hinge — a broken wire may make intermittent contact.
When to call a professional
If the door alignment has shifted (the dishwasher was bumped or the cabinetry has shifted), a technician can realign the door and mounting brackets.
