Led

There are three ON-StandBy led management modes:

A. StandBy mode: the user is informed when the machine is not carrying out

a programme; this flashing mode is active after stopping and resetting. The
led flashes at a frequency of about 1 Hz

B. Programme Acceptance Mode: the led flashes for about 3" at a frequency

of 10 Hz

C. ON mode: the led is always alight

Programme Setting

Normal programme setting:

• The machine starts from a StandBy position (led in mode A)

• The user selects a programme

• If the selector remains in the same position for at least 5" the machine
passes to the programme acceptance mode (led in mode B) and then to
ON (led in mode C)

• At this point the programme starts

• It does not change if the selector position is modified

• The user can stop the cycle by moving to the Reset position (marked with
a dot)

1.2 Timer Delay Setting

• The machine starts from a StandBy position (led in mode A)

• The user turns the selector to the desired delay

• If the selector remains in the same position for at least 5" the machine
passes to the delay acceptance mode (led in mode B) and then to ON (led
in mode C)

• The user selects a programme

• If the selector remains in the same position for at least 5" the machine
passes to the programme acceptance mode (led in mode B) and then to
ON (led in mode C)

• It is not changed if the selector position is modified

• The user can stop the delay count by moving to one of the Reset positions
for at least 5" (marked with a dot on the programme disc)

• When the count down is completed the machine starts its cycle and passes
to ON (led in mode C)

• It is not changed if the selector position is modified

• The user can stop the cycle by moving to one of the 5 Reset positions for
at least 5"

1.2.1 Wash Intensity Knob

Fig. 3

R

This knob allows the characteristics of the selected wash programme to be
changed. By turning it the wash becomes more intensive and the programme
duration increases (Relative symbols).
By turning it ANTICLOCKWISE the wash becomes more delicate and the cycle
duration decreases.

N.B.

It can be used only with the programmes for resistant and synthetic fabrics, ex­cept 3 and 7 (see timer selector).

1.3 Buttons

1.3.1 No spin button

By pressing this button the washing machine does not spin, but rotates
the basket at moderate speed. It should be used when the garments
that are being washed are difficult to iron.

1.3.2 Extra rinse button

This button is used to increase the number of rinses in the pro­grammes for resistant fabrics. It is recommended that this should be
used to improve the rinse when the machine has a full load and a lot
of detergent.

1.3.3 Stain removal button

By pressing this button the washing machine performs a more intensive
wash that improves the effectiveness of liquid additives (see chap. 5
BLEACH - STAIN REMOVAL BUTTON) thus allowing elimination of
even the most resistant stains.

1.3.4 Prewash button

This button allows a prewash to be performed in all programmes EX­CEPT wool.

N.B. When using this function the bleach cycle cannot be performed (Stain removal

button).

1.3.5 Anti-crease button

When this button is combined with programmes for synthetic fabrics
and silk/curtains it interrupts the wash programme leaving the gar­ments to soak before draining.

This function is important as it avoids creasing delicate and synthetic
fabrics (e.g. when it is not possible to take the laundry out at the end
of the wash but only a few hours later). The programme can be com­pleted by excluding the button.

N.B. If the machine is not provided with this button the programme can be completed

by turning the selector knob one notch.

1.3.6 Rapid Button

Press this button to reduce the wash programme duration by about
30%. It cannot be used with special programmes and with those for
wool and silk.

2 SPECIAL PROGRAMMES

40° AS 60°

It is a special programme that allows very good washing results to be ob­tained even at low temperatures.
By setting programme 3 at 40 ˚C and thanks to a special action of the washing
machine and an increase of the washing time, the results will be the same as
washing at 60 ˚C.

N.B. When using this programme the Intensive/Delicate knob is not active.

Daily

This machine has a programme for daily washing.
By setting programme 7 at 30 ˚C it is possible to wash lightly soiled garments
together, even if they are of different types and colours (max 3 KG).
This programme allows savings in time and energy because the cycle lasts
about 30 minutes.

N.B. Liquid detergent is recommended.

4 PARTICULAR PHASES

Antishock

In the event that the machine goes to a draining phase (e.g. Spin) and the wa­ter temperature is higher than the set limit (e.g. 60˚), the machine performs a
particular cycle before draining:

e.g.

1. Load 5 litres from Wash SV

2. Move 5" ON, 5" OFF, 25 rpm per 4'

3. If Temperature > Limit go to 1 otherwise go to 4

4. Drain + Spin

Antifoam

If there is too much foam in the machine during the spin it will carry out the
following cycle:

1. Stop for 2'

2. Load 10 litres from Wash SV

3. Move 5" ON, 5" OFF, 25 rpm per 2'

4. Restart the Spin that was interrupted at the beginning

This procedure is repeated until the foam problem is solved.
