Water Fill Tank; Water Softening System - Electrolux Diva Service Manual

3.1 WATER FILL TANK

The water fill tank is a container in transparent moulded plastic consisting of two
sections that are welded together.
- Inside the tank, special chambers and ducts define the path taken by the
water during the fill phase.
- The fill tank is positioned in the left-hand section of the appliance, and is
screwed into position from inside the tub using a fixing ring.
- The softener regulation system, if featured, is built into the fixing ring, and is
actioned by a knob.
The water fill tank is one of the main functional parts of the hydraulic circuit.

CONDENSATION OF STEAM
3.2 WATER SOFTENING SYSTEM (if featured)
If featured, the water softening system consists of a monobloc container
in transparent plastic. The container is subdivided into two sections,
which communicate through internal ducts and contain the salt and the
resin. The container is positioned in the base of the appliance and
screwed to the tub from the inside by a fixing ring.
- The container is connected to the water fill tank by two O-ring
connectors.
- It is also connected to the sump by an outlet duct.
The following components are fitted externally to the container:
- The salt sensor (A)
- The regeneration solenoid valve (B)
A normally-closed separation valve (*) is installed inside the container,
and serves to separate the two sections:
- The valve opens as a result of the pressure exerted by the water
during the regeneration process, when the regeneration solenoid
valve (4) opens.
SALT reservoir
The salt reservoir contains the salt used for regeneration, and is accessible for filling.
The salt sensor (A) indicates to the user that the salt reservoir requires topping up.
The sensor consists of a reed sensor positioned externally to the reservoir, and a magnetic float inside
the reservoir.
The sensor is connected electrically to the SALT LED on the control panel in versions with
electromechanical control; in electronic versions, it is connected directly to the PCB.
RESIN reservoir
This sealed reservoir contains the resins (organic substances used to purify the water).
The regeneration solenoid valve (B), when actioned, performs the regeneration process (cleaning of the
resins)
