5.4 Water Inlet Valve
The water inlet valve is mounted on the control panel. It performs the following tasks:
it moves the detergent dispenser lever mechanism, in order to direct water into the different
compartments during the wash programme.
It directs current to the following components:
–
Cold water solenoid valve
–
Tank drain pump
–
Circulation pump
–
Outlet pump
An electronic module supplies current to the stepper motor, which positions the inlet valve as required
during the washing programme. The stepper motor remains in circuit only for as long as it takes to
reposition the inlet valve.
If the stepper should continue to run, it is disconnected in order to reduce wear and tear on the contacts.

When the stepper motor (1) is switched on, the gear wheels (2) move the cam (3), which moves the lever
on the lever mechanism.
Brushes (5) are attached to the cam. These slide along the copper rails of the contact plate (6). The
contacts close at different times (see diagram), according to the position of the cam.
The cam follows a complete revolution in 15 seconds; as the contact plate is divided into 36 sectors,
each step takes approx. 0.4 seconds.
