DISTURBANCE
Interior light does
not work, but
compressor runs.
There is water in the
unit.
Cooling group starts
too often and for too
long.
Unit does not cool.
Side wall is very
warm (only for
models with foamed-
in condenser).
Sticker "OK" does not
appear.
POSSIBLE CAUSES
Bulb is defective.
Condensation drain hole is
completely closed.
The appliance door is opened too
often.
Air circulation around the unit is
obstructed.
Unit is switched off or is not
supplied with power.
Temperature controller is set to
"0".
Ambient temperature is too low.
The condenser releases warm air
into the environment. If the
ambient temperature is too high,
heat can build up. As soon as the
ambient temperature has dropped,
the unit cools normally again. It is
essential to observe the clearances
(see chapter 2.2).
Average temperature in this range
set too high.
Operating noises / troubleshooting
CAUSE / REMEDY
Caused by the compressor when it is
in operation.
Arises from the circulation of the

bottles and other containers.
Check if the condenser at the back of
the unit is loose.
Fasten the condenser.
MEASURES
Replace the bulb
(see chapter 4.4).
Clean the condensation
drain hole, e.g. with a
