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)

1.2Timer 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"

By resetting a programme the machine returns to the StandBy position (led in mode A).

The Door Lock led is only a user feedback to know when it is possible to open the door.

N.B. Even if the power supply is interrupted the programme that has been selected remains.

1.2.1Wash 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).

1.3Buttons

1.3.1No 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.

1.3.2Extra 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.

1.3.3Stain 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.

1.3.4Prewash 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).

1.3.5Anti-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.

1.3.6Rapid 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.

5 BLEACH - STAIN REMOVAL BUTTON

In case of bleaching it is necessary to insert an extra chamber 4 in the detergent drawer compartment 1; when pouring the bleach be careful not to exceed the max level indicated in the following figure.

Fig. 8

MAX

This washing machine is provided with a special function TO BE USED FOR BLEACHING (Stain removal button).

When bleaching is carried out separately pour the bleach into the supplementary chamber 4, press the stain removal button, switch the machine on and turn the selector to the rinse position after programme 4.

When bleaching is carried out during a normal washing cycle, pour the detergent and the additives into the appropriate compartments, press the stain removal button, switch the machine on and select the desired washing cycle.

N.B. Bleaching is not possible with the silk programme.

When the bleach chamber is used it is not possible to use the prewash function.
