end of the washing phase, the rinsing pro-
cess starts automatically and this is shown
by LED (h). Once rinsing has finished, the
machine shifts to the stand- by condition,
with LEDs (g) and (h) flashing. Flashing
stops when the door is opened or a new
cycle starts.
Press the key repeatedly to move from one
phase of the cycle to another. So, if was-
hing is on, press the key to shift to the rin-
sing process. During rinsing, press the key
to put the machine stand- by.

UTOMATIC YCLE TART
This selector determines the cycle starting
mode: If off (LED (i) off), starting the cycle
is by means of key (5). If on (LED (i) on), the
cycle starts automatically each time the
door is closed.
Pressing the key has the desired effect only
when the door is open.
D (7)
RAIN
This key works only if the machine has a
drain pump.
It has the desired effect only when the door
is open. Once pushed (LED (j) on), the drai-
ning cycle starts and will continue whether
the door remains open or is closed. By pus-
hing the key again, the draining cycle stops.
Upon completion of the draining process,
the machine remains stand- by for a few
seconds: after this interval, filling will start
again, unless the user has powered the
machine down by turning main switch off.
Adjustment of Working Temperatures:
(Figure B : Diagram of Electronic Board)
Temperatures are factory- set at:
· 55- 60ºC for the tub
· 85- 90ºC for the boiler
Temperature Adjustment:
In order to be able to adjust the tub and
boiler temperatures, the two microswitches
must be in the OFF position (Resistors
Disconnect: OFF). This way, the two resis-
tors remain live and temperatures can be
adjusted within the permissible range: 40-
70ºC for the tub and 70- 95ºC for the boi-
ler. Adjusting procedure:
· Check that the two resistors are on:
microswitches (3) in the lower position:
"Resistors Disconnect: OFF".
· Press the red key (Fig. B- 5) during 3
seconds to activate the temperature set-
ting function.
· The display shows the temperature then
predefined for the tub or the boiler
(depending on how many times you pres-
sed the key - Fig. A- 3).
· To adjust the temperature, there are two
potentiometers: B- 2 for the tub and B- 4
for the boiler (both clearly identified on
the silk- screened board, that also shows
the temperature ranges).
· Adjusting is done by turning the relevant
potentiometer clockwise to increase the
temperature and counterclockwise to
decrease it; the display showing the tub
or boiler temperature, whichever has
been selected with key (Fig. A- 3).
S (6) · After setting the required temperature,
ELECTOR
power the machine down and up with
main switch A- 1. As a result, the new
temperature is stored in the memory of
the electronic board.
Disconnecting the resistors:
In order to disable the heating of the resis-
tors, there are two microswitches (3) on the
board. So, placing the two microswitches in
the ON position will disconnect the two
resistors (Resistors Disconnect: ON).
Setting of rinsing time:
On this machine, it is possible to increase
the preprogrammed rinsing time by 0 to 4
seconds. This is achieved with potentiome-
ter (B- 1). By turning the potentiometer
clockwise, the preprogrammed rinsing time
can be increased by a maximum of 4
seconds.
Troubleshooting:
Only qualified technicians may work on the
connections of the electronic board, after
cutting out power to the machine with the
main switch and the automatic safety cir-
cuit- breaker at the external feeding point
to the machine.
The display shows the temperature probes

· E1:.......Boiler probe disconnected (circuit
open). Check the connections at the con-
nector (Fig B- c)
· E2:.......Boiler
Probe failed and must be changed.
· E3:.......Tub probe disconnected (circuit
open). Check the connections at the con-
nector (Fig B- c)
· E4:.......Tub probe short- circuited. Probe

The temperature transmitters are connec-
ted to the four- pin connector (Fig. B- c).
On the electronic board, there are several
light indicators which are very useful for
monitoring the machine operation and
malfunction. Those indicators belong to
either of two groups: input LEDs or output
LEDs.
Input LEDs: those associated with infor-
mation received by the electronic board.
Their location and description are indicated
on the silk- screened board and on Figure
B. The following are the amber LEDs:
· 'DOOR' LED: ON, when the door is closed.
· 'HIGH PRES.' LED: ON, when the high
· 'LOW PRES.' LED: ON, when the low pres-
· + Reserve LED: associated to a spare
· 'HIGH FLOAT' LED: Break Tank High Float
· 'LOW FLOAT' LED: Break Tank Low Float
Output LEDs: They identify the item that
has been activated by the microprocessor.

Accordingly, when one LED is on, the asso-
ciated component must also be active.
