6  Troubleshooting

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

, service 

number

2

 and 

appliance number

3

 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.

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, please 

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

-  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?

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

“Interior 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 

entirely as it should, the defective light bulb should be 

replaced as soon as possible.

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 

adjusting the adjustable feet, or move bottles and contain-

ers apart.

-  

Burbling noises

 are normal. These are caused by the refrig-

erant flowing round the refrigerant circuit.

  A short 

clicking sound

: This will be heard whenever  

the refrigeration unit (the motor) switches on or off automati-

cally.

  Motor noise:

 This will be slightly louder for a brief period 

when the refrigeration unit switches on.

Temperature is not cold enough

-  Is the temperature controller set correctly? (Set colder as 

needed).

-  Is the appliance door properly closed?

-  Is there sufficient ventilation?

  Unblock ventilation grill as needed.

-  Is the ambient temperature too hot? (see “Conditions” 

section)

-  Has the appliance been open too often or for too long?

-  Wait as needed, whether the required temparture has 

been set on its own.

Freezer 

compartment*

Do not use any elec-

trical heating or steam 

cleaning appliances, 

defrosting sprays, open 

flames or metal objects 

to remove ice. Risk of 

injury and damage to the appliance.

To accelerate the defrosting process, put a pan with warm, 

not boiling water into the compartment.

How to defrost:

W

  Switch off the appliance: Disconnect from the mains or

-  Turn the temperature setting to the “0” position.

W

 Remove frozen goods, put into newspaper or blankets and 

stored in a cool place.

W

 Leave the compartment and appliance door open during the 

defrosting process. 

W

  Collect defrosting water with a sponge or cloth. Then 

clean the appliance. 

Cleaning

W

  Before cleaning, always switch off the app-

liance. 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 appliance by hand with 

lukewarm water and a little detergent. Because of the risk 

of injury and damage to the appliance, steam cleaning 

equipment should not be used.

W

  Never use abrasive or scouring sponges. Do not use con-

centrated cleaning agents and never use abrasive or acid 

cleaners or chemical solvents. 

W

  We recommend using a soft cloth and an all-purpose clea-

ner with a neutral pH value. Only use food safe cleaning 

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 + deter-

gent). 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 often 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.

5  Defrosting, cleaning

* Depending on model and options

Defrosting

Appliances without freezer compartment defrost automatically. 

The moisture occurring at the back wall of the refrigerator 

is carried outside the refrigerator into an evaporating dish 

through the defrost water channel. The defrost water is 

evaporated by the compressor heat - water droplets on the 

rear wall depend on function and are completely normal.

W

  At least ensure that the defrost water can always flow out 

of through the outlet hole via the vegetable bin to the rear 

wall (arrow in Fig. A) unhindered.
