Quick answer

Miele refrigeration appliances show F144 when the freezer compartment door has been open for 15 minutes.

Model compatibility

Miele reuses codes across series and model years, so F144 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

At a glance

Code F144
What it means Freezer compartment door open for 15 minutes.
What you can check Close the freezer compartment door and confirm the symbol and tone have stopped. OK only stops the alarm early, and it sounds again after about a minute if the door is ajar.
When to call a technician If F144 stays lit with the freezer door shut, book a service visit. Have the code and your model number ready.

Response

  1. Close the freezer compartment door.
  2. Confirm the symbol and tone have stopped.

Per Miele’s KFNS 7734 D fridge-freezer manual, a door left open for a longer time triggers an alarm symbol on the display, a warning tone and a flashing light inside. Closing the door ends all three. Pressing OK stops the alarm early, with the light then staying on; with the door still ajar it sounds again after about a minute. Both the alarm delay and the tone can be altered in the settings. The manual itself only shows the symbol.
