ning cycle starts. By pushing the key again,
the draining 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:
· S
ETTING OF WASH TANK TEMPERATURE
1. With the machine off, set "Disconnect
Resistors" microswitch 1 (Fig. B- 1) to
position 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 elec-
tronic 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
position 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 elec-
tronic 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 tempe-
rature.
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
"Disconnect Resistors" microswitches (Fig.
B- 1) for disabling the heating of the resis-
tors. Therefore, setting both microswitches
to position ON disconnects the two ele-
ments("Disconnect Resistors" ON).
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
failure in accordance with the following
code:
· 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
failed and must be changed.
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
(Fig. B- 1) 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 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 following are red LEDs:
· "B.LAVADO" LED: ON, when wash pump
· "B.VAC" LED: ON, when drain pump is
· "EV.CAL" LED: ON, when rinsing electro-
board includes two
· "C - CALD." LED (boiler element contac-
· "C - CUBA" LED (wash tank resistor con-
· "EV.FRIA" LED: ON, when cold rinsing
· "EV.REG" LED": ON, when regeneration
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 exter-
nal item such as the relay or the resistor.
Model Configuration

possibility of increasing the cycle time
until the preset temperature is reached in
the boiler. So, in the event the temperatu-
re of the boiler were lower than the pre-
set value, the cycle would be extended
until the preset temperature is reached.
This prevents rinsing with cold water. In
order to enable this feature, select the
appropriate digit from the enclosed table.
