1 SAFETY
DANGER
Repairs may be carried out by a qualified electrician only!
The user may be put at risk and injured by improper repairs!
To prevent electric shocks, always comply with the following instructions:
► If the appliance is faulty, the housing or frame may be live!
► Electric shock may occur if live components are touched
inside the appliance!
► Before commencing repairs, disconnect the appliance from
the power supply!
► If tests have to be performed while the appliance is live,
always use a residual-current-operated circuit-breaker!
► The protective conductor resistance must never exceed the
values specified in the standard! The protective conductor is crucial for personal safety and appliance function.
► When repairs are complete, conduct a test in accordance with
VDE 0701 or the corresponding national regulations!
► When repairs are complete, perform a function and leak test.
WARNING
Comply with the following instructions:
If conducting the test in accordance with VDE 0701 via the connector, the heater (instantaneous water heater) must be tested directly for insulation faults due to all-pole disconnection (relays; pressure switch) or the differential current must be measured on the appliance!
If replacing the dispensing device and the pump sump, beware of sharp edges in the area of the stainless-steel modules.
Before commencing repairs, always disconnect the appliance from the power supply! If tests have to be performed while the appliance is live, always use a residual-current-operated circuit-breaker!
Sharp edges: Wear protective gloves.
Electrostatic sensitive devices! Please observe handling regulations.
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).
Connection dimensions for all 45 cm dishwashers
a = 1.4 m
b = 1.7 m

3.4 General information on control
3.4.1 Tap turned off
The appliance stops in the programme 6 minutes after the start of programme (scan filling position). The remaining running time is displayed unchanged. The control remains in this position until the filling level has been reached.
3.4.2 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.
The volume of water which has run through is calculated. Regeneration then takes place once the maximum possible number of rinse cycles has been reached.
The sequence characteristics of the regeneration electronics are described under Initial start-up / Replacing the electronics.
3.4.3 Warm water detection
If the water running in for the final rinse is hotter than 45 °C, the heat exchanger for the drying phase is not filled. In order to ensure the temperature difference required for condensation, the temperature in the final rinse cycle is increased to 72 °C, thereby increasing the inherent heat of the dishes.
3.4.4 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.
3.4.5 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.
3.4.6 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.
3.4.7 Components
The components such as the valves, the detergent and rinse aid dispensers (actuator) are actuated by triacs (see photo). The circulation pump, drainage pump and the instantaneous water heater are switched on by relays.
