Integrated Dispenser; Level & Anti-Overflow Pressure Switch; Anti-Flooding Device - Electrolux Diva Service Manual

4.13 INTEGRATED DISPENSER

The integrated dispenser consists of a plastic container comprising
two separate sections which contain Detergent (A) and Rinse-aid
(B).
- Fitted to the interior of the inner door and secured by two screws.
- The dispenser uses a single electrical coil connected to a
mechanical system and which performs both functions.
- When the coil is energized, it actions the mechanism via a series
of levers, thus introducing the contents in sequence (first
detergent, then rinse-aid).
- The dispenser is controlled by the timer (or PCB) at pre-
determined steps during the cycle to ensure correct dosing.
- A window to the side of the rinse-aid sector indicates the level of detergent (when the window is
clear, the detergent requires topping up).
4.14 LEVEL & ANTI-OVERFLOW PRESSURE SWITCH
These are two traditional pressure switches (pneumatic diaphragm type) connected to a special
support which is in turn secured to the right-hand upright by two screws.
4.14.1 LEVEL PRESSURE SWITCH
Determines the level of water introduced into the appliance.
Operating range: Intervention/Reset = 65/ 45mm
Operating characteristics: Empty/Full = Contacts 1-2 / 1-3
4.14.2 ANTI-OVERFLOW PRESSURE SWITCH
Ensures that the level of water in the appliance does not exceed
the safety threshold (overflow from the door).
Operating range: Intervention/Reset 129/ 105mm
Operating contacts: Empty/Full = Contacts = 1−2 / 1−3
- Connected electrically in series via contacts 1-3 to the drain pump.
- If the switch intervenes on Full (1-3), the drain pump switches on until the switch returns to Empty
(1-2)

4.15 ANTI-FLOODING DEVICE

This mechanical/electrical safety device is activated if water is
detected in the bottom of the appliance, if featured.
The device consists of a plastic container which contains a
sensor (floating type) and a microswitch.
It is fitted into a special housing inside the base of the
appliance.
Sensor (A):
- Extra-light polystyrene sensor whose position (at rest or
raised) determines the mechanical action of the microswitch.
Microswitch (B):
- This switch is connected in series to the fill solenoid, and opens or closes the contacts in order to
connect or disconnect the solenoid valve electrically.
- When at rest (solenoid valve energized), the electrical contacts are closed.
- Fitted into a housing in the container.
