1 SAFETY
1.1 Safety instructions
Danger!
►Repairs may be carried out only by customer service
engineers trained by the manufacturer!
►The user may be put at considerable risk and injured by
improper repairs!
►If the appliance is faulty, the housing or frame may be live!
►Do not touch components in the appliance. Even the modules
can be live!
►Before commencing repairs, ALWAYS disconnect the
appliance from the power supply!
►If tests have to be conducted while the appliance is live,
ALWAYS use a residual-current-operated circuit-breaker!
►The protective conductor connection must not exceed the
standardised values! This is essential if no persons are to be
injured and the appliance is to operate correctly!
►When repairs are complete, conduct a test in accordance with
VDE 0701 or the corresponding national regulations as well as
a performance test!
►Conduct a leak and performance test on the refrigeration
circuit.
1.2 Repair instructions
Caution!
►Comply with ESD information!
►NEVER attempt repairs by randomly replacing components!
►ALWAYS proceed systematically and comply with the
technical documentation for the appliance!
►As a rule, printed-circuit boards are not repaired but are com-
pletely replaced with original spare parts. Exceptions are
documented separately.
►When handling refrigerants, wear goggles and protective
gloves. If refrigerant splashes into eyes, rinse with plenty of
water.
►Pipe connections in refrigeration circuits must not be soldered.
Lokring connections must be used.

Not required

823_58300000113594_ara_en_u –26.03.2015 Seite 5 von 50
3 OPERATION
3.1 Freezer Set button
The freezer compartment temperature is adjusted with the left Set
button.
Setting range = –16 °C to –22 °C
Factory setting = –19 °C
3.2 Refrigerator Set button
The refrigerator compartment temperature is adjusted with the right
Set button.
Setting range = 2 °C –8 °C
Factory setting = 4 °C
3.3 Super Cool button
The coldest temperature setting is selected with the Super Cool
button.
Coldest refrigerator compartment temperature = 2 °C
Press the button again to deactivate the Super cooling function.
3.4 Super Freeze button
The coldest temperature setting is selected with the Super Freeze
button.
Coldest freezer compartment temperature = –22 °C
Press the button again to deactivate the Super freezing function.
3.5 Dispenser button
Three operating modes can be selected with the Dispenser button.
The three operating modes are: drinking water, crushed ice and ice
cubes.
If there is no button input for 1 h after selecting cubed ice or crushed
ice, the mode turns to drinking water.
3.6 Ice Maker Lock button

823_58300000113594_ara_en_u –26.03.2015 Seite 7 von 50
4 COMPONENTS
4.1 Control module
The control module is situated on the appliance.
The “Time shortening switch” reduces the run times.
e.g. compressor start-up lockout, fan switch-on delay, etc.
Briefly pressing the switch once reduces the time by 1 min.
Continuously pressing the switch reduces the time every two seconds
by 1 min. Maximum reduction time is 30 min.
4.2 Ice maker
The ice cube tray is swivelled by a motor. In doing so, the plastic tray
turns and the ice cubes fall out. The horizontal switch interrupts the
motor and the ice cube tray is moved back to the original position.
The ice cubes are ejected: after 130 min and when the ice sensor
is colder than –12.5 °C.
The ice sensor is situated under the ice cube tray.
The amount of ice presses the On / Off lever upwards and ice making
stops. When the amount of ice decreases, the lever drops and ice
making is restarted.

823_58300000113594_ara_en_u –26.03.2015 Seite 8 von 50
4.3 Drinking water tank
The storage container for drinking water is situated behind the
drawers.
Whenever water is dispensed, warmer mains water flows in. The cold
and warm water mixes and causes a temperature increase.
The water will taste stale if it is not dispensed for a prolonged period.
Empty the water tank so that fresh water can flow in again.
Capacity 1.5 l.

823_58300000113594_ara_en_u –26.03.2015 Seite 9 von 50
4.4 Vario box
The cold air flows in the rear area into the air inlet opening and moves
through the left side panel to the air outlet. The air flow rate is con-
trolled by an NTC sensor in the rear panel and via a flap in the air out-
let opening.
The flap is heated:
Heater = 5 W,
Flap open = heater off
Flap closed = heater on
Vegetables = 3 °C (required tempera-
ture)
Fish = –1 °C (required temperature)
Meat = –3 °C (required temperature)
Off = Vario box not supplied with cold
air
Select = Temperature selection
Test programme

5.2 Cooling system
The appliance features a single-circuit cooling system utilising
No-Frost technology with circulating air. The evaporator is situated
in the freezer compartment.
The refrigerator compartment fan supplies the refrigerator
compartment with cold air from the freezer compartment. The
refrigerator compartment fan runs whenever the refrigerator
compartment sensor requires refrigeration.
The air returns to the evaporator via an air conductor behind the
drawers.

6 REPAIR
6.1 Opening the refrigeration circuit
Whenever the refrigeration circuit is opened, always
replace the dryer before evacuating and filling the
refrigeration circuit.
6.2 Leaks on intake side
If the refrigeration circuit leaks on the intake side,
resulting in repairs, always replace the compressor and
dryer.
If atmospheric humidity penetrates the refrigeration
circuit, the oil in the compressor will be irreversibly
contaminated.
