6.3 Power feed and selection of programmes

The main board is powered directly by the terminal board. The connectors involved are E3 (neutral)

and E1 (line).

The control/display board (user interface) is powered by 5V supplied by the main board, so

programmes can be selected when the main board is turned on.

When the door is closed, the input board detects the closed contacts on switch (IP) between

connectors F1-F3 and starts the wash programme. The same switch supplies power to the electrical
components.

When the door is opened, power is shut off to the various loads and the cycle is paused.

7 Water

filling

7.1 Fill

circuit

7.1.1 Pressure switches on fill level and anti-overflow system

•

The level of water during filling is controlled by level pressure switch

(A)

•

The

anti-overflow pressure switch (B) makes sure that the level of

water during filling does not exceed the safety threshold (overflow
through the door).

7.1.2 Fill

system

The fill solenoid is powered by triac on the circuit board (connector A1) through the door switch (IP) and the
anti-flooding microswitch (DA).
