Information about
operating noises
Operating noises
In order to maintain the pre-set temperature
at a constant level, the appliance compressor
switches on from time to time.
The noises that can be heard while it is
running are perfectly normal.
The noise reduces automatically when the
appliance reaches its operating temperature.
The humming noise is emitted by the motor
(compressor). When the motor switches ON,
the noise may briefly increase in volume.
The bubbling, gurgling or whirring noise is
emitted by the refrigerant as it flows through
the pipes.
The clicking noise can always be heard
when the thermostat switches ON/OFF the
motor.
Cracking sounds may occur if ...
- the automatic defrosting is operating.
- the appliance is cooling down or
warming up (material expansion).
A multi-zone or No-Frost appliance may
cause a low hissing noise emitted by the
air flow inside the appliance.
If these noises are excessively loud, the
causes are probably not serious and are
usually very easy to eliminate.
The appliance is not level
Please level the appliance with the aid of
a spirit level. Use the height-adjustable feet
or place packing under the feet.
The appliance is not free-standing
Please move the appliance away from
kitchen units or other appliances.
Drawers, baskets or shelves are loose or
stick
Please check the detachable components
and, if required, refit them.
Bottles and/or receptacles are touching
each other
Please move bottles and/or receptacles
away from each other.

Minor problems and how
to rectify them yourself
Customer service should NOT be
contacted for every fault. Most faults
are minor. Therefore, before you call
customer service, please check whether
you can eliminate the fault yourself based
on the following information.
A technician who is called out to rectify
a minor fault will charge the customer, even
if the appliance is still under guarantee.
If the indicators for temperature

selection, (Fig. /3 and 6), do not
illuminate:
check that the power is ON, that the plug is
correctly inserted in the socket and that the
appliance is switched ON.
If the refrigerator-compartment light does
not function:
– The light bulb is defective. Pull out
the mains plug and remove the cover
A
(Fig. /A). Replace the defective light bulb
with a light bulb of the same type
(max. 15 W, 230 V, E14 holder).

– The light switch is sticking (Fig. /B).
Check whether it can be moved. If not,
please call customer service.
If the "Alarm" indicator illuminates after a
prolonged period of operation:
Fault, it is still too warm in the freezer
compartment!
Possible causes of the fault:
– The clearance at the top of the appliance
or in the base is blocked,
– The freezer-compartment door has not
been closed correctly,
– Fresh food was frozen without Fast freeze,
– Too much fresh food was frozen at once,
– High ambient temperature.
The "Alarm" indicator goes off after
elimination of the fault, if the freezer
compartment has reached its normal
operating temperature again.
If the freezer section door has been kept
open for a long time and the temperature
inside now no longer reaches the pre-set
level,
Minor problems and how
to rectify them yourself
so much ice has formed on the evaporator
(source of cold temperature) that it cannot
be defrosted by the fully automatic
defrosting system. In this case take the
frozen goods out of the freezer, wrap them
well to keep them cold and store them
somewhere cool.
Switch off the appliance and open the
freezer section door. After about 12 hours
the ice on the cooling system will have
thawed. Switch the appliance on again and
put the frozen goods back inside.
If you are not able to rectify the problem
with the help of the suggestions listed here,
please call Customer Service.
Do not open the door more often than
necessary, so that the cold temperature
inside is retained for as long as possible.
Do not take any further action, especially
with regard to the electrical parts of the
appliance.
