Error code F307
Appliance Coffee Machine
Quick answer

F307 on a Miele coffee machine means a clogged milk valve. The manual walks through cleaning it and refitting the holder.

Model compatibility

Miele reuses codes across series and model years, so F307 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

F307 means the milk valve is clogged.

What F307 means

F307 on a Miele coffee machine means the milk valve is clogged. A second cause is a milk valve holder that is not inserted correctly.

Cleaning the milk valve

  1. Open the appliance door and remove the bean container on the left and the maintenance container.
  2. Remove the central spout’s stainless steel cover.
  3. Swivel out the milk valve cover using the pin on its top right-hand side. This cover should only be cleaned by hand.
  4. Detach the milk pipework from the dispensing unit on the central spout and from the milk valve holder, then remove the pipework connecting the valve to the spout.
  5. Disconnect the angular moulded hose from the round hose and rinse the hoses under running water. Do not remove the connecting pieces from the hoses.
  6. Press the latches on the left and right of the milk valve holder and pull the holder forwards.
  7. Take the holder and silicone seal apart, pull the stainless steel bolt up and out, and clean the individual valve components in the dishwasher.

If the holder is not seated

Remove the holder together with the silicone insert and reattach it correctly. It locks into position with an audible click.
