Possible cause and remedy
The ventilation gaps are covered or have become too
dusty.
 Do not block the ventilation gaps.
 Clean the dust from the ventilation gaps on a
regular basis.
The door has been opened too frequently, or a large
amount of fresh food has been placed inside the
appliance.
 Only open the door when necessary and for as
short a time as possible.
After a while the temperature will return to normal by
itself.
The ambient room temperature is too high. The higher
the room temperature, the longer the compressor will
run.
 See the information in "Installation – Location".
The temperature setting is too low.
 Correct the temperature setting.
The SuperCool function is still switched on.
 To save energy, you can switch SuperCool off
early yourself.
This is not a fault. The temperature is too high.
 Correct the temperature setting.
 Check the temperature again after 24 hours.
The door alarm has been activated (see also "Door
alarm").
 Close the appliance door.
The alarm will stop.
No tools are required to change the door seal.
 Change the door seal. A replacement is available
from Miele.
