Cause and remedy
The ventilation gaps in the housing unit have been
covered or become too dusty.
 Do not block the ventilation gaps.
 Dust the ventilation gaps regularly.
The door has been opened too frequently, or a large
amount of fresh food has been placed inside and/or
frozen at the same time.
 Only open the door when necessary and for as
short a time as possible.
The required temperature will re-establish itself after a
while.
The door is not properly closed.
A thick layer of ice may have formed in the freezer.
 Close the door.
The required temperature will re-establish itself after a
while.
If a thick layer of ice has formed, it will reduce effi-
ciency and increase the energy consumption.
 Defrost the appliance and clean it.
The ambient temperature is too high. The higher the
room temperature, the longer the compressor will run
for.
 See "Installation - Location".
The appliance was not properly installed in the niche.
 See "Installation - Building in the appliance".
The temperature setting is too low.
 Adjust the temperature.
The Super freeze function is still switched on.
 You can switch off the Super freeze function earlier
to save energy.
