(f): Long Cycle.
Choosing the adequate cycle depends on
how soiled trays and utensils are. The dir-
tier they are, the longer the cycle has to be
for an intensive, thorough washing.

TART YCLE
If you press this key, the wash cycle starts
and the associated LED (g) turns on. At the
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.

TART ELECTOR
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.

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 / Pag. 26: 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 tempera-
tures, the two microswitches must be in the
OFF position (Resistors Disconnect: OFF).
This way, the two resistors remain live and
temperatures can be adjusted within the
permissible range: 40-70ºC for the tub and
70-95ºC for the boiler.
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 setting
function.
· The display shows the temperature then
predefined for the tub or the boiler (depen-
ding on how many times you pressed 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
decrease it; the display showing the tub or
boiler temperature, whichever has been
selected with key (Fig. A-3).
· After setting the required temperature,
power the machine down and up with main
switch A-1. As a result, the new temperatu-
re is stored in the memory of the electronic
board.
Disconnecting the resistors: In order to
disable the heating of the resistors, 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 preprogram-
med rinsing time by 0 to 4 seconds. This is
achieved with potentiometer (B-1). By tur-
ning the potentiometer clockwise, the pre-
programmed rinsing time can be increased
by a maximum of 4 seconds.
Troubleshooting: Only qualified techni-
cians may work on the connections 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
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 short-circuited. 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 mal-
function. Those indicators belong to either
of two groups: input LEDs or output LEDs.
Input LEDs: those associated with informa-
tion received by the electronic board. Their
to location and description are indicated on
the silk-screened board and on Figure B.
The following are input LEDs:
·Door LED: ON, when the door is closed.
·High Pressure Switch LED: ON, when the
high pressure switch is on, meaning that
the tub is full.
·Low Pressure LED: ON, when the low
pressure switch is on, meaning that the
water level has reached the bottom pressu-
re switch.
·Reserve LED: associated to a spare input.
·Break Tank High Float LED: ON, when the
high float has been actuated, meaning
there is water up to this level.
·Break Tank Low Float LED: ON; when the
low float has been actuated, meaning the
water level has reached this point.
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 output LEDs:
·Pressure Pump LED: ON, when the pres-
sure pump is working.
·Drain Pump LED: ON, when the drain
pump is active.
·Solenoid Valve LED: ON, when water is
