phase priot to rinsing. The associated LED (j)
will then turn on.
Press the key repeatedly to move from one
phase of the cycle to another. So, if washing is
on, press the key to shift to the rinsing process.
During rinsing, press the key to put the machi-
ne stand-by.

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 draining
cycle starts. By pushing the key again, the drai-
ning cycle stops.
Upon completion of the draining process, filling
will start again, unless the user has powered
the machine down by turning main switch off.
Adjustment of Working Temperatures: (Figure
B Electronic Boad Diagram)
Temperatures are factory-set at:
· 55-60ºC for the wash tank
· 85-90ºC for the boiler
Setting temperatures:

ETTING OF WASH TANK TEMPERATURE
:
1. With the machine off, set "Disconnect
Resistors" microswitch 1 (Fig. B-1) to posi-
tion ON (1 ON, 2 OFF).
2. Switch the machine on and wait until the
display stops showing the model number
and shows a temperature.
3. Now press button (Fig. B-2) on the electronic
board until all three 'Select Cycle' LEDs (Fig.
A-d, e, f) and the 'Wash Tank" LED (Fig. A-a)
turn on simultaneously. The display shows
the preset wash tank temperature.
4. Use the pushbutton "Start Cycle" (Fig. A-4) to
increase the temperature setpoint or push
button "Drain" (Fig. A-5) to decrease it.
5. Press "Select cycle" (Fig. A-3) to save the
selected temperature. The three "cycle"
LEDs turn off and the display confirms
correct saving of the value.
6. Switch the machine off.
7. Set "Disconnect Resistors" microswitch 1
(Fig. B-1) to position OFF (1 OFF, 2 OFF).
· S
ETTING OF BOILER TEMPERATURE
:
1. With the machine off, set "Disconnect
Resistors" microswitch 2 (Fig. B-1) to posi-
tion ON (1 OFF, 2 ON).
2. Switch the machine on and wait until the
display stops showing the model number
and shows a temperature.
3. Now press button (Fig. B-2) on the electronic
board until all three 'Select Cycle' LEDs (Fig.
A-d, e, f) and the 'Boiler" LED (Fig. A-b) turn
on simultaneously. The display shows the
preset boiler temperature.
4. Use the pushbutton "Start Cycle" (Fig. A-4) to
increase the temperature setpoint or push
button "Drain" (Fig. A-5) to decrease it.
5. Press "Select cycle" (Fig. A-3) to save the
selected temperature. The three "cycle"
LEDs turn off and the display confirms
correct saving of the value.
6. Switch the machine off.
7. Set "Disconnect Resistors" microswitch 2
(Fig. B-1) to position OFF (1 OFF, 2 OFF).
Disconnecting the elements
The electronic board includes two "Disconnect
Resistors" microswitches (Fig. B-1) for disabling
the heating of the resistors. Therefore, setting
both microswitches to position ON disconnects
the two elements("Disconnect Resistors" ON).
Troubleshooting
Only qualified technicians may work on the con-
nections of the electronic board, after cutting
out power to the machine with the main switch
and the automatic safety circuit-breaker at the
external feeding point to the machine.
The display shows the temperature probes fai-
lure in accordance with the following code:
· E1 :.......Boiler probe disconnected (circuit
open). Check the connections at the connec-
tor (Fig B-c)
· E2 :.......Boiler probe short-circuited. Probe fai-
led and must be changed.
· E3 :.......Tub probe disconnected (circuit open).
Check the connections at the connector (Fig B-c)
· E4 :.......Tub probe short-circuited. Probe failed
and must be changed.
The temperature transmitters are connected 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 information
received by the electronic board. Their location
and description are indicated on the silk-scree-
ned board and on Figure B. The following are
amber LEDs:
· "PUERTA" LED: ON , when the door is closed.
· "PRESOST" LED: ON , when pressure switch
is on, the tub is full.
Output LEDs: They identify the item that has
been activated by the microprocessor. Their
location and description are indicated on the
silk-screened board and on Figure B. The follo-
wing are red LEDs:
· "B.LAVADO" LED: ON , when wash pump is
working.
· "B.VAC" LED: ON , when drain pump is wor-
king.
· "EV.CAL" LED: ON , when rinsing electroval-
ve is active.
· "C - CALD." LED (boiler element contactor):
ON, when boiler resistor is heating water.
· "C - CUBA" LED (wash tank resistor contac-
tor): ON, when wash tank resistor is heating
water.
· "EV.FRIA" LED: ON , when cold rinsing water
solenoid valve is active.
· "EV.REG" LED": ON , when regeneration
solenoid valve is active.
Example
: If the "Boiler Resistor" LED is on and
the resistor does not heat up, this means that the
microprocessor gives the order correctly and the
fault lies in an external item such as the relay or
the resistor.
Model Configuration
Control of cycle time (Thermal Lock) as a
function of the boiler temperature:
· The electronic controller features the possibi-
lity of increasing the cycle time until the preset
temperature is reached in the boiler. So, in the
event the temperature of the boiler were lower
than the preset value, the cycle would be
extended until the preset temperature is rea-
ched. This prevents rinsing with cold water. In
order to enable this feature, select the appro-
priate digit from the enclosed table.
Selection of model
The machine model number appears on the
display for 2 seconds once the main switch is
turned on. In order to select another model
number, proceed as follows:
1. Power the machine down.
2. Set the two microswitches (Fig B-1) to posi-
tion "ON" (1ON, 2ON).
3. Power the machine up.
