FAULT
POSSIBLE CAUSES
MEASURES
Side wall is very
warm (models with
foamed-in condenser
only).
The condenser gives off warm air
to the environment. If the
ambient temperature is too high,
heat accumulation can occur.
Once the ambient temperature
has dropped, the appliance will
refrigerate again normally. Be
sure to maintain the prescribed
clearances (see chapter 2.3).
No actions necessary.
"OK" sticker does not
appear.
Average temperature in this area
is set too high.
Set the temperature regulator
to a colder setting. Only
change the temperature
regulator gradually and wait
for approximately 12 hours
before checking again.
A layer of frost or ice
forms on the rear
inner wall.
High room temperatures (such
as on hot summer days) and a
high temperature regulator
setting can lead to continuous
refrigerating operation. The
compressor must run
continuously to maintain the set
temperature in the appliance.
The appliance is not able to
defrost automatically as this is
only possible when the
compressor is not running
(see chapter "Defrosting").
Set the temperature regulator
to a lower setting. The
compressor will start and stop
as usual and automatic
defrosting will continue.
