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.
→
SuperCool 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.
