7 Malfunctions
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.
→ Due to the various speed steps, speed-regulated*
compressors can generate different running noises.
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
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 1.2)
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 symbol Fig. 3 (4) flashes together with the
temperature display.
→ There is a fault.
u Please contact the after-sales service (see Maintenance).
DEMO shines in the temperature display.
→ The demo mode is activated.
u Please contact the after-sales service (see Maintenance).
The outer 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) .

u Wait to see whether the appliance reaches the required
temperature by itself. If not, please contact the after sales
service (see Maintenance).
→ Too much fresh food was placed inside without SuperFrost.
u Solution: (see 5.9)
→ 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 door gasket is defective or should be replaced for
other reasons.*
→ In some units, the seal around the door can be replaced.
You will not need any special tools to do this.
u Please contact the after-sales service (see Maintenance).
