What the F33 Fault Code Means
The F33 fault code indicates that the door has not opened automatically as expected at the end of the programme. On Miele dishwashers with an AutoOpen drying function, the door is designed to open slightly at the end of the cycle to aid drying. When this mechanism fails, or the door lock does not release correctly, F33 is displayed. Miele confirms this is a technical fault that cannot be remedied by the user.
Common Reasons This Fault Appears
Door lock or latch fault
The door lock mechanism may have failed, preventing the door from releasing or opening automatically as programmed.
AutoOpen mechanism fault
On models with AutoOpen drying, the motor or mechanism that pushes the door ajar at the end of the cycle may have failed.
Control board fault
An issue with the main electronic control module can prevent it from triggering the door release at the correct point in the cycle.
Wiring fault
A loose or damaged electrical connection to the door lock or AutoOpen mechanism can cause this fault to appear.
Safe Checks You Can Try
Check for obstructions
Ensure there is nothing preventing the door from opening — check that the dishwasher is not positioned too close to adjacent furniture or cabinets that could obstruct the door opening mechanism.
Restart the dishwasher
Switch the machine off at the mains and leave it unplugged for a few minutes. Reconnect the power, switch back on and restart the programme. A power reset can sometimes clear a temporary fault.
Miele advises that if the fault persists after a reset, the appliance cannot be repaired without professional assistance.
