Care and maintenance
8.1
Cleaning
For hygienic storage, the interior should always be kept clean.
Do not use any abrasive cleaning agents or scouring cloths. Clean wooden
shelves just with a slightly damp cloth without any detergent.
Risk of damage to the appliance.
▸ Clean the interior, as required, with a mild soapy solution and wipe dry thoroughly.
▸ Clean the operating and display elements just with a slightly damp cloth.
▸ Regularly check the door seals and if dirty clean using a soft brush and clean water.
Wipe dry.
▸ If the appliance is not to be used for a longer period of time, switch it off. Empty and
clean the appliance. Leave the appliance door open.

Defrosting
The appliance regularly defrosts automatically, rendering manual defrosting unnecessary.

Noises and warnings
9.1
Operating noise
The appliance can make various noises during operation. Although the appliance is
noise-optimized, some noise cannot be eliminated completely. This noise depends on
the size of the appliance, how it is installed and the cooling requirements (e.g. fast cool-
ing), the ambient temperature and the installation conditions. Operating noises are partic-
ularly audible immediately after switching on the compressor; however, these noises be-
come quieter as the appliance runs.
Unusual noises are often caused by improper installation. The appliance must be in-
stalled on a level and stable surface. In open kitchens or in the case of appliances in-
stalled in partitioned areas, normal operating noises may seem louder. This is not a fault
but rather an effect of the design/architecture.
