Cleaning

W

  Before cleaning, always switch off the appli-

ance.  Disconnect from the mains or un-screw 

or switch off the fuse.

W 

Wash shelves, glass plates and other options by 

hand.

W

  Clean the outer walls, inside and equipment by hand with 

lukewarm water and a little detergent.  Because of the 

risk of injury and damage to the appliance, steam clean-

ing equipment should not be used.

W

  Do not use abrasive sponges or scourers, do not use 

     concentrated cleaning agents and never use cleaning 

     agents containing sand, chloride or acid or chemical 

solvents, as these would damage the surfaces and could 

cause  corrosion.

W

  We recommend using a soft cloth and an all-purpose 

cleaner with a neutral pH value. Only use food safe clean-

ing materials inside the appliance. 

W

For stainless-steel appliances*:

-    Clean the side panels and door surfaces with a clean 

and soft cloth. If necessary, use a moist cloth (water + 

detergent). Alternatively, use a micro-fibre cloth.

W

  Ensure that no cleaning water penetrates into the electri-

cal components, drain gulley* or ventilation grilles.

  Wipe the appliance dry.

W

  Do not damage or remove the type plate on the inside of 

the appliance.  It is very important for servicing purposes.

W

  Clean the 

drain hole on the rear 

wall above the vegetable bins 

frequently, fig. 

A, arrow.

  If necessary, clean with a thin 

object, e.g. a cotton swab or 

similar.

W

  Ensure that none of the wires or other components are 

dislodged, bent or damaged.

W

  Then connect/switch on the appliance.

If the appliance is to be

 left switched off for any length of 

time, empty the appliance, disconnect from the mains, clean 

as described above and leave the door open so as to avoid 

odours.

7 Troubleshooting

6 Cleaning

* depending on model and options

Your appliance is designed and manufactured in such a way 

as to provide fault.free operation and a long service life.

Nevertheless, if a fault should occur during operation, ple-

ase check whether the fault is due to incorrect operation. In 

this case we have to charge you for any costs incurred also 

within the warranty period.

You can eliminate the following faults yourself by checking 

the possible causes:
Fault 

possible cause and remedy

Appliance not working, display is unlit

-   Is the appliance switched on properly?

-   Is the mains plug properly inserted in the socket?

-   Is the socket fuse intact?
The interior light does not come on

-  Is the refrigerator compartment switched on?

-  Was the door open for longer than 15 min.?

-   The bulb is defective. Change the bulb as described in 

"Interior light".

Loud running noise

-   Is the appliance standing firmly on the floor, or does the 

compressor cause nearby items of furniture or objects to 

vibrate?

  If necessary, move the appliance slightly, align by adju-

sting the adjustable feet, or move bottles and containers 

apart.

-  The following are normal:  

Flow noises, bubbling or dripping, coming from the 

coolant in the refrigerating circuit.

  A soft clicking sound, this always occurs when the refrige-

ration unit (the motor) switches on or off automatically. 

  Motor noise; this will be slightly louder for a brief period 

when the refrigeration unit switches on. When SuperFrost 

is switched on, fresh food is inserted, or when the door is 

open for a long time, the refrigerating capacity increases 

automatically. 

The compressor will continue to run for a while

-  On energy saving models, this is caused by the func-

tions and is perfectly normal. When less refrigeration is 

required, the VCC compressor switches to a low speed. 

It will then be running almost constantly, but it does save 

energy.

The inverter regularly flashes every 15 seconds*

. 

-  The inverter is equipped wth a diagnostic LED. 
-  The flashing is normal.

Customer service and type plate

If none of the above causes applies and you cannot 

eliminate the fault yourself or if more than one LED 

is flashing, please contact your nearest after-sales 

service point (see list attached). 

Please state the 

appliance designation  

1

, 

  service number 

2

,

appliance number 

3

of the rating plate (see fig.),

and 

which LED displays 

are flashing so as to ensure 

rapid, accurate servicing. 

The rating plate is located 

inside the appliance on the 

left-hand side.

Keep the appliance closed until the after-sales service tech-

nician arrives in order to prevent further loss of refrigeration.
