If a Miele W1 will not start because the door will not lock, the display gives a specific message: Service Door lock, fault F34, which Miele explains as the door not closed properly so the door lock could not engage. The fix is to close the door again and start the program again; if the message returns, contact Miele Service. Check that nothing is trapped at the door seal, that the door closes with a firm push, and that the display is not waiting for a PIN code, which also stops a program starting.

Model-specific
What is true of this model and not of its siblings
- Where to find the model plate
- Miele asks you to quote the model and serial number when you contact Miele Technical Service; both are on the data plate above the porthole glass when the door is open. Give that with the exact display message, since F34 and F35 both involve the door but point to different faults.
- Standby and energy saving
- The display switches off automatically to save energy after a while, and the machine switches off automatically too. A dark display with a working outlet is usually standby: turn the program selector or press any button before assuming the door or the power has failed.
- Miele parts for this problem, part numbers and prices
- For fault F34 that persists with a clear door, Miele's own shop lists the door latch sub-assembly, part number 9090941, at $36.00 and the electromagnetic lock, part number 9865648, at $119.00 (prices change). Confirm the model on the data plate above the porthole glass before ordering.
