-  Is the appliance switched on?

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

rior light".

Interior light on when Cool-Plus activated:

-  This is necessary from a technical point of view and is  

quite normal.

-  To be able to ensure that the Cool-Plus function works en-

tirely as it should, the defective light bulb should be replaced 

as soon as possible.

Appliance does not work:

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 an operating error. Please note that even 

during the warranty period the resultant servicing costs in this 

case will have to be borne by the owner.

You may be able to rectify the following faults by checking the 

possible causes yourself:

Malfunction 

Possible cause and remedy

5  Troubleshooting

Loud running noise:

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

pressor cause nearby items of furniture or objects to vibrate?  

If necessary, move the appliance slightly, align by adjusting 

the adjustable feet, or move bottles and containers apart.

-  

Burbling noises

 are normal. These are caused by the refriger-

ant flowing round the refrigerant circuit.

  A short 

clicking sound

: This will be heard whenever the refrig-

eration 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.

The temperature is not cold enough:

-  Is the temperature setting correct? If necessary, set a lower 

temperature.

-  Loose thermometer in appliance is showing a wrong reading.

-  Does the door close properly?

-  Is the appliance sufficiently well ventilated? Clear ventilation 

grilles if necessary.

-  Is the ambient temperature too hot? (See "Safety regulations")

-  Has the appliance been opened too often or left open too long?

-  If applicable, wait until the appliance reaches the required 

temperature itself.

Customer service and type plate

If none of the above causes apply and you cannot 

rectify the fault yourself, please contact your nearest 

customer service department (see enclosed list for 

addresses). State the 

type designation

1

 as given on the type plate, so 

as to ensure rapid, accurate servicing. The type plate is located 

inside the appliance on the left-hand side.

-   Is the appliance switched on properly?

-   Is the mains plug properly inserted in the socket?

-   Is the socket fuse intact?

4  Defrosting, cleaning

Defrosting

The refrigerator compartment

defrosts automatically. The defrost water is evaporated 

by the heat from the compressor; drops of water on the 

rear wall are perfectly normal.

W

  Ensure that the defrost water can flow freely through the 

drain hole in the rear wall (arrow in fig. 

A

).

The freezer compartment

After a long period of operation, a layer of frost or ice can 

build up inside the freezer compartment.

W

  To defrost, switch off the appliance:

-  Disconnect the appliance from the mains or

-  set the temperature control to "0".

W

  If possible, put the frozen goods in the freezer drawer, wrap 

in newspaper or a blanket and store in a cool place.

W

  To speed up the defrosting process place a saucepan of hot 

but not boiling water on one of the middle shelves.

  Do not use electric heaters or steam clean-ers, defrost-

ing sprays or naked flames for defrosting nor any metal 

objects for removing the ice. Risk of injury and damage!

W

  Leave the appliance door open when defrosting.

  After defrosting, mop up the remaining water with a sponge 

or cloth and clean the appliance.

Cleaning

W

  Before cleaning, always switch off the appliance.  

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 cleaning equip-

ment 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 sol-

vents, 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 cleaning materi-

als 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 + deter-

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

W

  Ensure that no cleaning water penetrates into the electrical 

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 dis-

lodged, 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.
