Error code F146
Appliance Refrigerator
Quick answer

F146 on a Miele refrigerator tells you the freezer compartment door was left open for 45 minutes.

Model compatibility

Miele reuses codes across series and model years, so F146 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

The freezer compartment door has been open for 45 minutes.

A Miele refrigerator showing F146 is reporting that its freezer compartment door has been open for 45 minutes.

Fix from the owner’s manual

The manual gives one instruction: close the freezer compartment door.

The matching door alarm

The operating instructions for the KFNS 7734 D fridge-freezer name no F14x codes. They do describe the door alarm for a door left open too long: an alarm symbol shows in the temperature display of that compartment, an audible alarm sounds and the interior lighting flashes. Shutting the door ends it. Tap OK to stop it sooner; the light then stays on, and the alarm repeats after around 1 minute if the door is still open. Miele says the trigger time can be changed, and the sound switched off, in the further settings.

Earlier warnings in the same series

  • F145 appears earlier for the same freezer door.
  • F144 appears even sooner.
  • F143 belongs to the fridge compartment door.
