What the F85 Fault Code Means
The F85 fault code indicates that even though the slide shutter motor has been activated, no signal change has been detected at the position switch — meaning the control board cannot confirm that the shutter has moved. Miele confirms this is a technical fault that cannot be remedied by the user.
Common Reasons This Fault Appears
Faulty slide shutter position switch
The position switch that signals shutter movement to the control board may have failed, preventing any change in signal from being registered.
Faulty slide shutter motor
The motor driving the slide shutter may have failed, meaning the shutter is not actually moving despite the motor being activated.
Mechanical obstruction
An obstruction preventing the shutter from moving will result in no signal change at the position switch.
Wiring fault
A loose or damaged connection to the position switch or motor can cause this fault to appear.
Safe Checks You Can Try
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.
