  • What does Fault F73 mean on a Miele coffee machine?

    Miele describes F73 / Fault 73 on its countertop coffee machines as meaning that the brew unit cannot move to its start position. The first checks therefore concentrate on the brew unit, its cleanliness and its position rather than unrelated parts of the machine.

  • Can cleaning the brew unit clear Miele F73?

    It can. Miele specifically includes cleaning the brew unit within its F73 troubleshooting guidance. Coffee residue or grounds can interfere with normal operation. If cleaning and correctly refitting the brew unit doesn't solve the problem, follow the appropriate reset procedure for your model.

  • What if Miele F73 keeps coming back?

    A recurring F73 after the brew unit has been cleaned, correctly installed and the recommended reset attempted suggests the machine needs further investigation. Avoid forcing the brew unit or repeatedly trying to operate a mechanism that is struggling to move.

  • Switch the machine off and back on

    Switch the coffee machine off, wait briefly and restart it. Allow the machine to complete its normal start-up sequence. If F73 returns, the brew unit is still unable to reach its required start position and further checks are needed.

  • Remove and clean the brew unit

    If your Miele model has a removable brew unit, remove it according to the machine instructions and clean it thoroughly. Coffee grounds and residue around the brewing mechanism can interfere with its movement. Allow the brew unit to drain before refitting it.

  • Clean inside the brew-unit compartment

    With the brew unit removed, inspect the accessible compartment for loose grounds and compacted coffee. Pay particular attention to areas where accumulated grounds could obstruct the brew unit as it moves. Do not reach into or interfere with inaccessible internal mechanisms.

  • Check the brew unit is correctly positioned

    Before refitting, check that the brew unit is in the correct position and hasn't become displaced. Reinstall it carefully and make sure it is fully seated. Never force the brew unit into the machine if it doesn't fit normally.

  • Try Miele's brew-unit reset procedure

    For affected Miele countertop machines, Miele's F73 guidance includes a procedure for returning the brew unit drive to its basic position. This involves removing the brew unit, closing the machine with the brew unit still removed, switching the machine on and allowing the drive to initialise before switching it off and reinstalling the brew unit. Follow the procedure for your exact model, as controls and steps can differ.

  • Investigate a persistent F73 fault

    If the brew unit is clean, correctly installed and the reset procedure doesn't clear F73, don't repeatedly force or cycle the mechanism. The machine may have a problem with the brew-unit drive, positioning or another part of the brewing mechanism that requires further diagnosis.
