At a glance

Code F143
What it means Fridge compartment door open for 45 minutes.
What you can check Close the fridge compartment door. The warning symbol, tone and blinking light stop once it shuts, and OK only silences them for about a minute.
When to call a technician Phone for a technician if the code outlasts a closed door. Tell them the door has been shut and the code is still showing.

Step

  1. Close the fridge compartment door.

What Miele’s manual shows

The fridge-freezer manual (KFNS 7734 D) leaves out the F14x numbers yet covers the same event as a door alarm. A warning symbol appears beside the compartment’s temperature, the alarm sounds and the light inside blinks until the door shuts. The alarm can be silenced early with OK, but it returns after roughly a minute while the door stays open. Both the alarm delay and the buzzer are adjustable in the settings.
