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

The Ice Maker Lock button locks the Dispenser button. Ice cubes

cannot be dispensed, only water can be dispensed

The Ice Maker Lock button interrupts ice making.

823_58300000113594_ara_en_u – 26.03.2015 Seite 6 von 50

3.7 Lock button

The Lock button locks all buttons on the display.

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

Enter programme:

► Hold down the Select button for 2 sec.

The Vario box temperature is displayed

► Press the Select button once

OP is displayed and the Vario box flap is opened.

► Press the Select button twice

CL is displayed and the Vario box flap is closed.

Exit programme:

Automatically after 20 sec.

823_58300000113594_ara_en_u – 26.03.2015 Seite 10 von 50

4.5 Bar compartment flap

The bar compartment flap is situated on the refrigerator door.

The light is on when the bar compartment flap is open.

823_58300000113594_ara_en_u – 26.03.2015 Seite 11 von 50

The light switch and the seal can be changed.

4.6 Freezer compartment fan

Fan operation:

► The freezer compartment fan always runs whenever the

compressor is running.

Exceptions:

► The freezer compartment fan starts with a switch-on delay of

60 s after the compressor starts.

► The freezer compartment fan does not run if one of the two

doors is open.

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.

6.3 Location of sensors

6.3.1 Freezer compartment / refrigerator compartment sensor

Both sensors can be changed.

Prise off the sensor boxes with the flat blade of a screwdriver. The fan

cover in the refrigerator compartment must be removed before the

refrigerator compartment sensor can be changed.

6.3.2 Evaporator sensor

The air conductor in the freezer compartment must be removed before

the evaporator sensor can be changed.

6.3.3 Ice-maker sensor

The ice-maker sensor is located under the ice tray. The sensor can

be changed.

6.3.4 Ambient temperature sensor

The ambient temperature sensor is located on the control electronics

module. The sensor cannot be changed.
