Electrical Components; Terminal Block; Pushbutton; Timer - Electrolux Diva Service Manual

4 ELECTRICAL COMPONENTS

4.1 TERMINAL BLOCK

The terminal block consists of a junction box to which the power
cable is connected; the wiring is then routed to the appliance's
ON/OFF switch.
The terminal block is pressure-fitted into a housing inside the
base. A suppressor is built into the terminal block.
The suppressor is an electrical device designed to filter out radio
interference.
Correct operation of the suppressor requires that the appliance
be connected to an efficient ground connection.

4.2 PUSHBUTTON

The pushbutton array consists of one or more modular buttons
(maximum 4) in a single block (the individual buttons are pressure-
fitted into a metal support).
The pushbutton array is located inside the control panel and
secured by two screws.
The pushbuttons are of two types, with different functions:
- Switch (two-pole) for the ON/OFF key
- Deviator (single-pole/two-pole) for the Option keys.

4.3 TIMER

The timer is a timer-controlled electrical device which controls the duration and the
execution of the operations that comprise the washing cycle.
All the "user" components (solenoid valve, pump, heating element etc.) are
connected electrically to the timer by means of a specific wiring harness.
The signals to the user components are transmitted via the contacts (switching)
fitted to a lateral support and actioned by a series of cammes.
The movement of the cammes is transmitted by a synchronous motor via a series
of levers and gears which, in turn, advance the timer from one step to the next.
One complete rotation of the timer is subdivided into 58 steps, each with a specific
duration (step time variable between 5 sec and 24 sec).

4.4 LATCH ASSEMBLY

Closure of the door is performed by a mechanical locking/release
system which also connects and disconnects the electrical components
in the appliance.
The latch is positioned inside the inner door in the upper section, and is
secured from the exterior by two screws.
The assembly consists of the latch, which also features a built-in
microswitch.
Latch:
The latch is in plastic material in which a system of levers provides the
mechanical action.
Microswitch:
The microswitch is connected electrically (in series) to the ON/OFF
switch, and opens or closes the contacts in order to connect or
disconnect the machine from the power supply. The microswitch is
pressure-fitted into a housing in the latch.
