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.

→

SuperCool is activated.

u

The  compressor  runs  for  longer  in  order  to  rapidly  cool  the

food. This 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.

→

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  refrigeration  increases  automatically  when  the  Super-

Cool  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 standing firmly on the floor. As a result,

adjoining  units  or  objects  are  set  into  vibration  by  the

running refrigeration unit.

u

Move  the  appliance  away  a  little  and  align  it  using  the

adjustable feet.

u

Move bottles and containers apart.

The temperature display indicates: 

F0

 to 

F9

→

There is a fault.

u

Contact the customer service. (see Maintenance).

The temperature display indicates power failure

. The

warmest temperature reached during the power failure

appears in the temperature display.

→

The freezer temperature rose too high over the last hours or

days due to a power failure or power interruption. When the

power  interruption  is  over,  the  appliance  will  continue  to

operate in the last temperature setting.

u

To  cancel  the  display  of  the  warmest  temperature:  press

alarm button

Contact the customer service. (see Maintenance).

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 5.7.4)
