7 Malfunction
Your appliance is designed and manufactured for a long life
span and reliable operation. If a malfunction nonetheless
occurs during operation, check whether it is due to a handling
error. In this case you will have to be charged for the costs
incurred, even during the warranty period. You may be able to
rectify the following faults yourself:
Appliance does not work.
→ The appliance is not switched on.
u Switch on the appliance.
→ The power plug is not properly inserted in the wall socket.
u Check power plug.
→ The fuse of the wall socket is not in order.
u Check fuse.
The compressor runs for a long time.
→ The compressor switches to a low speed when little cold is
needed. Although the running time is increased as a result,
energy is saved.
u This is normal in energy-saving models.
→ SuperFrost is activated.
u The compressor runs for longer in order to rapidly cool the
food. This is normal.
A LED on the bottom rear of the appliance (at the
compressor) flashes regularly every 15 seconds*.
→ The inverter is equipped with a diagnostic LED.
u The flashing is normal.
Excessive noise.
→ Speed-controlled* compressors may produce varying
running noise due to different speed steps.
u The sound is normal.
A bubbling and gurgling noise.
→ This noise comes from the refrigerant flowing in the refriger-
ation circuit.
u The sound is normal.
A quiet clicking noise.
→ The noise is produced whenever the refrigeration unit
(motor) automatically 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 automatically when the Super-
Frost, 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 1.2)
A low hum.
→ The sound is produced by air flow noise of the fan.
u The sound is normal.
Vibratory noise.
→ The appliance is not fixed to the ground. The running of the
cooling unit therefore makes objects and adjacent furniture
vibrate.
u Adjust appliance via the height-adjustable feet.
u Move bottles and containers apart.
The SuperFrost button flashes together with the tempera-
ture display.
→ There is a fault.
u Contact the customer service. (see Maintenance).
All LEDs are illuminated in the refrigerator compartment
temperature display.
→ Demo mode is activated.
u Please contact the after sales service. (see Maintenance).
The outside surfaces of the appliance are warm.
→ The heat of the refrigeration circuit is used to prevent
condensate from forming.
u This is normal.
The temperature is not cold enough.
→ The door of the appliance is not properly closed.
u Close the door of the appliance.
→ Insufficient ventilation.
u Clear ventilation grilles.
→ The ambient temperature is too high.
u Solution: (see 1.2) .
→ The appliance was opened too frequently or for too long.
u Wait until the appliance reaches the required temperature
itself. If not, contact the customer service. (see Mainte-
nance).
→ Too much fresh food was placed inside without SuperFrost.
u Solution: (see 5.4.4)
→ The appliance is too close to a source of heat (stove, heater
etc).
u Change the position of the appliance or the source of heat.
The interior light is not on.
→ The appliance is not switched on.
u Switch on the appliance.
→ The door was open longer than 15 min.
u The interior light automatically switches off if the door has
been open for about 15 min.
→ If the interior light is not on but the temperature display is lit,
the bulb is faulty.
u Change the bulb. (see Maintenance).
8 Decommissioning
8.1 Switching off the appliance.

u To switch off the entire appliance it is necessary only to
switch off the freezer compartment. In so doing, the refriger-
ator compartment is automatically switched off as well.
8.1.1 Switching off the freezer compartment
u Using a coin, turn the temperature control of the freezer
compartment Fig. 3 (1) to 0.
w The temperature displays are dark.
8.1.2 Switching off the refrigerator compart-
ment
u Using a coin, turn the temperature control of the refrigerator
compartment Fig. 3 (6) to 0.
w The temperature display is dark.
Note
u If only the fridge section is to be switched off, e.g. during
holiday periods, always make sure that: the temperature
