2 INSTALLATION
2.1 Aligning the appliance
To ensure a perfect locking function and prevent leaks in the area of
the door, the appliance must be aligned precisely via the heightadjustable feet. If the appliance is integrated, the middle rear heightadjustable foot can be adjusted from the front.
Note: Built-under and built-in appliances.
Using the height-adjustable feet, raise the appliance until the housing
touches the worktop.
The installation instructions (drilling template) are required for
attaching the furniture front to integrated and fully integrated
appliances.
The tensile force of the door springs in integrated and fully integrated
appliances can be adjusted to the weight of the furniture door (See
Door spring point).
To prevent injury, a side cover 481271 can be fitted near the hinges of
end appliances which are built in or under or are free-standing.
2.2 Electrical connection
Connect the appliance to a correctly installed earthed socket only.
Comply with the specifications on the rating plate.
2.3 Water connection
If the appliance is connected to the drain with the standard hose
length, the max. permitted height from the floor is 90 cm. If the
drainage hose is extended, a max. height of 80 cm must not be
exceeded. The water connection (¾ inch) requires a conventional
water line with a water pressure of at least 0.5 bar (0.5 at.) (when the
tap is turned on, the water flow rate must be more than 8 l/min.). If the
water pressure is more than 10 bar (10 at.), a pressure reducing valve
must be installed.
The appliances can be connected to warm water up to 60 °C.
However, it is recommended to connect the appliance to cold water
(better drying and washing results).

Intensive 70°
The programme consists of a wash cycle at 35°/45º, one intermediate
rinse, final rinse at 55° without
drying. The Aqua sensor is not active
in this programme.
The programme consists of a prerinse at 50°, wash cycle at 70°, two
intermediate rinse cycles, final rinse at 70° and a drying cycle. Please
ensure that only the bottom basket is rinsed until the temperature is
reached.
Prerinse
The programme consists of a prerinse only. The Aqua sensor is not
active in this programme.
Auto 55°–65° (depending on model)
In the auto programme the Aqua sensor decides not only on a water
change after the prerinse, but it also specifies the temperature of the
wash cycle and the number of intermediate rinse cycles. If clean water
is detected in the prerinse, the water from the prerinse is also used in
the wash cycle, a wash cycle at 65°, one intermediate rinse cycle and
a drying cycle. If dirty water is detected in the prerinse, the prerinse
cycle runs, a wash cycle at 51°, two intermediate rinse cycles and
a drying cycle.
ECO 50°
The programme consists of a wash cycle at 50°, one intermediate
rinse cycle, final rinse at 66° and a drying cycle. The Aqua sensor is
not active in this programme. Please ensure that only the bottom
basket is rinsed until the temperature is reached.

3.3 General information on control
3.3.5 Sensors
All outgoing signals from the door switch, the level switch, the NTC
sensor and the refill switches are recorded and evaluated by the
microprocessor at the required time.
3.3.1 Regeneration electronics
The electronics determine, in comparison with the water hardness set
on the appliance, the volume of water which is possible until the
softening system is exhausted.
3.3.6 Tap closed
The appliance detect that the tap is closed when it does not receive
any signal from the flow sensor after 30 seconds.
The number of rinse cycles are counted. Regeneration then takes
place once the maximum possible number of rinse cycles has been
reached.
3.3.7 Components
The sequence characteristics of the regeneration electronics are
described under Initial start-up / Replacing the electronics.
The components such as the valves, the detergent and rinse aid
dispensers and the circulation pump are actuated by triacs (see listing
of triacs). The drainage pump and the instantaneous water heater are
switched on by relays.
3.3.2 Warm water detection
If the water running into the final rinse cycle is hotter than 45 °C, the
temperature in the final rinse cycle is increased to 72 °C in order to
increase the inherent heat of the dishes. The heat exchanger is not
filled.
3.3.3 Memory electronics
The electronics module has its own memory which remembers the
programme last selected. If no new selection is made at the start of
the programme, the programme last selected will run.
3.3.4 Power failure
The electronics module has a power failure memory function which
ensures that the current rinse programme continues in the event of
a power failure or programme interruption.

4 COMPONENTS
4.1 Actuator
The thermo hydraulic system consists of a metal cylinder with plunger.
The cylinder is filled with a substance which expands greatly when
heated. The heat source is a PTC (positive temperature coefficient)
which is in direct contact with the metal cylinder. A strong pressure
spring returns the plunger back to its original position when the heat
source is switched off.
When voltage is applied to the PTC, the PTC heats up and transfers
the heat to the wax-filled metal cylinder. The wax expands and forces
the plunger out of the cylinder. The plunger transfers the mechanical
movement to the release mechanism for dispensing the detergent and
rinse-aid. If the heat source is switched off, the volume of wax is
reduced by the cooling process. The pressure spring returns the
plunger back to its original position. The actuation time is approx.
2 min., the reset time approx. 3 min.

Resistance 0.5–1.5 kΩ
202_58300000104305_ara_en_b – 02.11.a Seite 13 von 53
4.2 Aqua sensor (optional)
A
= Photodiode
B = Infrared diode
C = Detergent solution
The infrared light-emitting diode and the photodiode are located
opposite each other in a U-shaped translucent housing on a board.
The infrared diode transmits infrared light through the water flowing
between the U to the light-sensitive base of the photodiode which then
becomes conductive.
If the water is turbid, the light emitted by the infrared diode can no
longer reach the photodiode. The absent voltage signal is detected by
the microcomputer. Depending on the programme type, the water is
changed after the prerinse or even the washing temperature is
changed. If the turbidity value is not reached, the water remains in the
rinsing tank for the wash cycle. In each programme sequence in
which the Aqua sensor is active the sensor is also calibrated. If
a calibration cannot be implemented successfully, a permanently
stored programme is executed and an error is saved in the module.
202_58300000104305_ara_en_b – 02.11.a Seite 14 von 53
4.3 Aqua Stop valve
The valve system consists of two valves in series, which are actuated
electrically parallel, and the filler valve and safety valve. The safety
function may be actuated via the safety level chamber or electrically
via the float in the base pan. The water flow is then stopped
mechanically. An electric solenoid valve which is enclosed by
a housing is attached to the tap. The housing is connected to the base
pan by a leakage water hose (sleeve of the inlet hose). The water inlet
hose, which connects the valve to the water inlet, and the electrical
control line for the solenoid valve are located inside this leakage water
hose.
Technical specifications:
Nominal voltage 230–240 V
A
