Cause and remedy
This is not a fault. The temperature setting is too high.
 Correct the temperature setting.
 Check the temperature again after 24 hours.
The frozen goods begin to defrost.
The room temperature is too low for this refrigeration
appliance.
If the room temperature is too low, the compressor
will run less frequently. This may cause the freezer
section to become too warm.
 See "Installation – Location".
 Increase the temperature of the room.
The door seal has come out of its groove.
 Check that the door seal is correctly positioned in
the groove.
The door seal is damaged.
 Check whether the door seal is damaged.
No tools are required to change the door seal.
 Change the door seal. A replacement is available
from Miele or from specialist retailers.
This is not a fault. Condensation has settled on the
panel and frozen.
This could be due to:
– the appliance door being opened too often, or
being left open.
– a large amount of food is being frozen at once.
– an increase in humidity levels in the room.
 Keep the door closed as much as possible. The
NoFrost system will automatically defrost the layer
of ice over the next few days.
