2. FUNCTIONING:
2.1. PRODUCT FEATURES AND TECHNOLOGICAL INNOVATIONS:
DRUM ASSEMBLY:
The drum assembly is held up by three springs, it is
5°-inclined to make the machine more ergonomic
and to facilitate the introduction of clothes into the
drum, whose maximum capacity is 7,5 Kg.
REMARK: the right position of the springs is
important to maintain a correct inclination.
DISPENSER:
It is like a traditional dispenser, with the same prin-
ciples of functioning. It is placed inside the machine,
behind the door; you can reach it by opening the
door.
Some models are equipped with Push-Push lock.
OKO SYSTEM:
The Oko ball is placed inside the tube, connecting
the drum to the drain pump.
The drum is provided with a rubber ring, which ab-
sorbs the noises produced by the contact of the Oko
ball with the drum.

PRESSURE SWITCH:
The connection of the pressure switch tube is placed
in the lower part of the drum, but not on the level
with the pump tube, as in other washing machines.
Its housing is obtained by die-casting and it is the
final part of an air trap, which determines the right
functioning of the washing machine.
HOWTO OPENTHE DOOR, BLOCKED
IN CASE OF AN EMERGENCY:
There are special circumstances which cause the
blockage of the door, for example a prolonged inter-
ruption of power supply, any blockage of the pump,
impossibility to open the door; the clothes inside the
machine can be recovered after having unlocked the
door, even if there is water in the tank. This proce-
dure must be performed, paying attention to the fol-
lowing safety instructions:
1. Switch off the washing machine
2. For further safety reason, unplug the washing
machine (remember that water could drop on the
floor).
3. Using a flat-type screw driver, remove the plinth
of the machine.
4. Pull the emergency cord at the bottom on the left
to unlock and open the door.
DOOR:
The door of this washing machine is a single as-
sembly composed by the lock, the hinges, the dis-
play board cable, the door, the inner door.

WATER FILLING:
Water filling can occur in two phases: the first is common to all the programs, the filling is controlled by the
pressure switch; the second phase, performed by some programs only, water filling changes according to
the wash cycle of the washing machine setting.
To know if a program performs a second water filling, look at the wash diagrams in the appendixes (from
page 34 to page 42).
For example, in the diagram below (standard wash cycle at 40°), after a first water filling controlled by the
pressure switch, the machine performs a second water filling (1 litre + 1 litre of water) of two litres of water.

Rinse:
Mini Load
It makes clothes
whiter, perfectly
clean.
It reduces creases
on the clothes, mak-
ing the ironing
easier.
It makes the rinse
more efficacious.
It is suitable for loads
equal to or lower than the
half of the maximum ca-
pacity of the machine.
The machine increases the quantity of water to be
supplied and the cycle grows longer to wash very
dirty clothes intensely.
It reduces the creases changing wash and spin pro-
grams. At the end of the cycle, the drum slowly turns
at regular intervals to avoid the formation of creases
on the clothes. The “Easy Iron” light flashes during
this phase. In case of selection of the “Silk” program,
the clothes remains soaked and the light flashes up
to press Start/Pause button or “Easy Iron” button.
It permits another rinse to assure the whole elimination of
detergent. It is especially useful to people with skin sensi-
tive to detergents. It is advisable to start the machine with
a full load and to use a high dosage of detergent (look at
the Appendix: Wash data table)
It lowers power and water consumption and shortens the
duration of the wash cycle. REMARK: Use a dosage of
detergent which is equal to or lower than the half of the
maximum quantity provided for this cycle.

5.2. AUTO TEST (TESTING / RUNNING_IN):
The Hardware Key permits the execution of the platform EVO II Auto Test program.
On the hardware key switches on a BLUE LED, indicating it is an EVO II washing machine. A flashing
RED led on the key (when it is connected with the appliance) indicates that the electronic board is
communicating with the hardware key. If the hardware key does not succeed in connecting with the
washing machine, the message “ERR” will flash on the display
Initial conditions to start Auto Test:
1. Washing machine without water in the tank.
2. Door closed.
3. Switch on the washing machine and fit the key on the suitable housing.
Remember that the Auto Test program activates the heater to warm up water and controls the spin;
so it is necessary to select a temperature higher than 30°C and not to exclude the spin.
To start the AUTO-TEST program, press and leave the button marked as AUTO-TEST. A sound-
signal will be given out and on the display will slide the writing “AUTO-TEST”.
Auto Test sequence for Washing Machines and Washer Dryer
- Loading of wash solenoid valve for 10" ca.
- Loading of pre-wash solenoid valve for 10" ca.
- Loading of hot water solenoid valve for 10" ca (in machines equipped with this solenoid valve).
- Motor movement on both directions.
- Activation of the wash heater: warming up to the temperature of 30°C.
- Drain and spin.
- Stop.
NOTICE!! If now the washing machine works correctly, but previously it has had a FAULT, it will not start up
the AUTO-TEST program, but such a FAULT will be surely shown on the display of the hardware key.
In this case, to start up the “Auto-test” program is necessary to remove the hardware key.
