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 doors have been opened too
frequently, or a large amount of fresh food has been
put in all at once for storage or freezing.
 Only open the appliance doors when necessary
and for as short a time as possible.
After a while, the temperature will return to normal by
itself.
The appliance doors are not closed properly. A thick
layer of ice may have formed in the freezer.
 Close the appliance doors.
After a while, the temperature will return to normal by
itself.
If a thick layer of ice has already formed, this will
affect cooling and increase energy consumption.
 Defrost the refrigeration appliance and clean it.
The ambient room temperature is too high. The higher
the ambient temperature, the longer the compressor
has to run.
 See the information in "Installation" – "Location".
The temperature setting in the refrigeration appliance
is too low.
 Correct the temperature setting.
A large amount of food is being frozen at once.
 See "Freezing and storing food".
The SuperCool function is still switched on.
 You can switch off the SuperCool function earlier
to save energy.
The SuperFreeze function is still switched on.
