Error code F143
Appliance Refrigerator
Quick answer

F143 on a Miele refrigerator means the fridge compartment door has been open for 45 minutes.

Model compatibility

Miele reuses codes across series and model years, so F143 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

Fridge compartment door open for 45 minutes.

F143 is the Miele alert for a fridge compartment door that has been open for 45 minutes.

Fix

Close the fridge compartment door.

The matching door alarm

Miele’s operating instructions for the KFNS 7734 D fridge-freezer do not print the F14x codes, but they describe the door alarm for a door left open: an alarm symbol lights in the temperature display, a buzzer sounds and the interior light flashes. Closing the door stops all three. Tapping OK ends the alarm early and leaves the light on, and if the door is still open the alarm sounds again after about 1 minute. The delay before the alarm and its sound can be changed in the appliance settings.

Where it fits

  • F142 comes before it.
  • F141 is the first door alert.
  • F146 is the freezer-door counterpart.
