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.
→ SuperCool is activated.
u The compressor runs for longer in order to rapidly cool the
food. This is normal.
