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 repeatedly every 5 seconds*.
→ There is a fault.
u Please contact the after-sales service (see Maintenance).
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 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 Check installation and reposition appliance as required.
u Move bottles and containers apart.
The temperature display indicates: F0 to F9
→ 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) .
