6 Maintenance
6.1 Manual defrosting
The refrigerator compartment is defrosted automatically.
The defrost water evaporates as a result of the heat of the
compressor. Drops of water on the rear wall are perfectly
normal.
u Regularly clean the drain opening to allow the water to flow
away (see 6.2) .
A layer of frost or ice can build up in the freezer compartment
after a long period of operation.
The layer of frost or ice builds up faster if the appliance is
opened often or if the food is warm when placed inside.
However, a thick layer of ice will increase the appliance‘s
energy consumption. You should therefore defrost the appli-
ance regularly.
CAUTION
Risk of injury and damage as a result of hot steam!
u Do not use electric heaters or steam cleaners, naked flames
or defrosting sprays for defrosting.
u Do not remove ice using sharp instruments.
u Switch off the appliance.
u Pull out the power plug or switch off the fuse.
u If possible, put the frozen goods in the freezer drawer,
wrapped in newspaper or a blanket, and store in a cool
place.
u Place a pan with hot, not boiling
water on a middle shelf.
w Defrosting is speeded up.
w Defrost water is collected in the drawers.
u Leave the door of the appliance open while defrosting.
u Remove detached pieces of ice.
u If necessary, pick up defrost water several times, using a
sponge or cloth.
u Clean the appliance (see 6.2) .
