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.

performed by turning the small switch on the device to TEST for at least 5";
the machine carries out a set cycle described in position 35 of the line graph).

6.3 Autotest
Should the washing machine not be found to be in error, it is possibile to
check by means of a Hardware key and using a specific autotest cycle, activated as follows:
1. Take LB to reset (coloured ball) for at least 5" and wait for the led to flash
in reset mode
2. Insert the hardware key through the serial socket
3. Turn the switch on the serial key to Test
4. Wait for the hatch to lock and the switch to start turning.
5. Turn the switch on the serial key to PC
The machine will carry out the following cycle:
• The switch will turn to position 0 (12h if the machine has a delay, programme 1 if the machine does not have a delay)
• Wash solenoid valve loads for approx. 10"
• Pre-wash solenoid valve loads for approx. 10"
• Wash and pre-wash solenoid valves load at the same time until the pressure switch is complete
• Heats up to 30° and moves the motor in both directions
• Moves the switch forward by 9 turns
• Unloads and spins
• The switch will turn to one of the reset positions
• STOP
The test cycle can be repeated as many times as necessary using the same
method.
The test cycle can be stopped by turning the switch to one of the reset positions.

These are shown in a display located on the instrument panel of LVB2000 machines Evolution Indesit.
From fault F01 to fault F15
Are those that are indicated according to the version via LED stand by/on or
display positioned on the Wash Dry machine Ariston/Indesit panel.
6.4.1 Reading the Fault
The fault on the machine is shown by:
1. The continuous rotation of the switch
2. The activation for the first 4", of the solenoid valve and discharge pump
3. The hatch is blocked
4. The LED flashes:
the number of flashes is equal to the fault code; l code must be read as follows:
• Each rapid flash (2/3 very rapid flashes of the LED) represents a code
value.
• The fault code is assessed counting the number of flashes in a time of _
seconds one from the other.
• The count is stopped when the LB waits for approx. 8/9" between two
flashes.
• The procedure is repeated cyclically by the machine.
