Operating Instructions

Problem Possible Cause Correction
The compressor
runs for a long
time.
When less refrigeration is required,
the speed-controlled compressor
switches to a low speed. Although
the running time is increased as a
result, energy is saved.
u
This is normal in energy-saving models.
SuperFrost function is activated.
u
The compressor runs long to rapidly freeze food.
This is normal.
An LED at the
lower rear of the
appliance (near
the compressor)
flashes regularly
every 5
seconds*.
There is a fault.
u
Contact the customer service department (see Main-
tenance).
Noises are too
loud.
The different speed levels of speed-
controlled* compressors can cause
them to generate various noises
during operation.
u
These noises are normal.
A gurgling
sound
This sound comes from the refrig-
erant flowing in the refrigeration
circuit.
u
The sound is normal.
A faint clicking
sound
The sound always occurs when the
refrigeration unit (the motor) automat-
ically switches on or off.
u
The sound is normal.
A hum. It is
briefly a little
louder when the
refrigeration unit
(the motor)
switches on.
The refrigeration increases automati-
cally when the SuperFrost function is
activated, fresh food has just been
placed in the appliance or the door
has been left open for a while.
u
The sound is normal.
The ambient temperature is too high.
u
Solution: (see 1.3)
A low hum
The sound occurs as a result of fan
air flow.
u
The sound is normal.
Vibration noise
The appliance is not standing firmly
on the floor. As a result, objects and
adjoining units are set into vibration
by the running refrigeration unit.
u
Check the installation and realign the appliance if
necessary.
u
Move bottles and containers apart.
Flow noise on
the soft stop
mechanism.
The sound is caused by the soft stop
mechanism.
u
The sound is normal.
The temperature
display indi-
cates: F0 to F9.
There is a fault.
u
Contact the customer service department (see Main-
tenance).
The SuperFrost
symbol Fig. 2 (13)
flashes together
with the temper-
ature display.
There is a fault.
u
Contact the customer service department (see Main-
tenance).
