too low.

Cause and remedy
The ventilation gaps have been covered or become
too dusty.
 Do not block the ventilation gaps.
 Dust the ventilation gaps regularly.
The appliance door has been opened too frequently,
or a large amount of fresh food has been placed in
the appliance for freezing.
 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 appliance door is not properly closed. A thick
layer of ice may have formed in the freezer.
 Close the appliance door.
After a while, the temperature will return to normal by
itself.
If a thick layer of ice has formed, it will reduce effi-
ciency and increase the energy consumption.
 Defrost the refrigeration appliance and clean it.
The ambient room temperature is too high. The higher
the room temperature, the longer the compressor will
run for.
 See the information under "Installation – Location".
The temperature setting in the refrigeration appliance
is too low.
 Correct the temperature setting.
The SuperFreeze function is still switched on.
 You can switch off the SuperFreeze function earlier
to save energy.
