3. Self-test

The Self-test checking routine performs a component verification sequence without the

need to intervene once it is running. At the end of each of the steps, the following is

launched.

Before launching the Self-test routine it is recommended to carry out the following

operations:

•Connect a 20A/AC reading scale 2 digits Digital Ammeter, in series to one of the

phases of the mains current, on the mains wire of the appliance. This will allow

to verify the components during the test.

•Carefully empty the drum of the washing machine, because during the Auto-test

sequence the unbalance safety provided by the software is disabled.

•Set the Program Selector's Knob [A] to the OFF position and wait for 30 seconds

before to launch the self-test.

Activation of the self-test routine:

1. Set the Programs Selector Knob [A] to the second Washing Program after the

OFF position in clockwise sense. Wait a moment for the display to turn off. The

display will remain off for approximately 1 second.

2. Push the first Button to the Left [C] under the LCD screen while the display is off

until the display shows 0:80 and all the LEDs on the screen remain illuminated.

3. Within 5 seconds, push the Start/Pause Button [B]. From this moment on, the

self-test routine will be carried out automatically.

Description of the steps of the self-test routine:

Step

Description

Water is loaded to complete the "base level" of 6 litters, through the

Detergent's Compartment for Pre-wash (I).

1 second of pause.

It's now fed for about 10 seconds, the Water Heating Element (from about

4.5A to about 8A on the Digital Ammeter, depending on the type of

featured Heating Element).

The water load continues through the Detergent's Compartment for Main

Wash (II). It's fed the Motor for the tumbling of the Drum in clockwise

sense at 55 rpm and for about 16 seconds.

Pause of the Motor for ~ 4 seconds and the water load continues with the

simultaneous feeding of both Solenoid Valves, to fill up the Detergent's

Compartment for Softener (❀).

The water load continues for both Solenoid Valves and it's fed the Motor

for the tumbling of the Drum in Anticlockwise sense at 55 rpm, for the

time of about 12 seconds.

It's fed the Drain Pump, until the "empty tank" Pressure sensor condition.

It's carried out a Short Spin Phase, lasting about 15 seconds, at the half of

the maximum speed available.

If the machine is a Washer-Dryer, are simultaneously activated the Drying

Heater Element (for the first 5 seconds - about 5.90A at 220-230V/AC) and

the Solenoid Valve for Steam Condensation together with the Drying fan

(for a total of 15 seconds).

(*) Only for LSI5 1480

End of the Self-test sequence. The display and all the leds are flashing.

SET THE PROGRAM KNOB BACK TO OFF AND UNPLUG THE MACHINE. LET THE

MACHINE BE OFF FOR AT LEAST 30", to be sure that the Self-test procedure has been

reset. Actually, the washing machines with these power cards remain in "standby"

condition (electrically powered power card) even if the Program Knob is in OFF position.
