5) SELFTEST  

 
In the lower part of the electronic board, at the right side of the microprocessor, there are two small pins (contacts). 
To enter in the self-test mode, keep them in short-circuit while switching on the machine. This can be made also 
using a screwdriver, paying much attention to avoid touching other alive parts of the electronic board. 
 
Two numbers will appear on the displays: the left one has no meaning, while the one at the right side is the release 
number of the software. 
The upper and the lower leds remain lit, and this can be helpful to place correctly the sticker of the keyboard if it has 
to be changed. 
 
Press ON/OFF push- button to test the displays: letters UAO appear at the left side, then at the right side, then 888 
appears on both the displays. 
 
When the left-

hand display shows letters I O, the push buttons, including “TIME SET” and “ON/OFF”, can be tested. 

Pushing one button, its number is shown on the display and the rele

vant led turns on. “TIME SET” is nr. 9 “ON/OFF” 

is nr. 10. 
Pressing ON/OFF, the test of the buttons ends and the temperature probes are checked. The left hand display shows 
the temperature read by the lower probe and the right-hand display shows the one read by the level probe. Toughing 
the probes it is possible to see the temperatures changing. 
 
Pressing TIME SET, the outputs of the electronic board are checked. 
Push-button 1 is used to make the test. When an output is ON, led WAIT is on, when the output is OFF, the led 
READY is on. 
Push-button 2 is used to go to the following output and button 3 to go back to the previous one. 
Initially the left-hand display shows U 1, i.e. output 1, which is the one of the control switch of the water heater. 
Pressing 1 the output is activated, the control switch makes and the element becomes hot. 
Pressing 2 the display shows U 2, which is the output of the air blower. 
U 3 is the left-hand motor when it lifts the basket and U 4 the same motor when it lowers the basket. 
 
In order to test also the microswitch of the motor, it is better to remove the baskets before making the test. 
In this way the motor shaft can turn freely and the lever of the microswitch can enter and exit from the slot of its cam. 
When the left-hand microswitch feels the slot, the led of the left-hand push-button 1 turns on, while when testing the 
right-hand microswitch, the led of the right-hand push-button 1 turns on. 
U 5 is the right-hand motor lifting the basket. 
U 6 is the right-hand motor lowering the basket. 
U 7 is the sauces element. 
U 8 is the water solenoid-valve. 
U 9 e U A are not in use. 
 
Pressing TIME SET the program exits from the self-test. 
 

6) SAUCE HEATER (only in PL6 model) 

The sauce-heater basins are placed on a thermostatically-controlled heating plate. 
The working temperature of this plate should be left fixed, but should regulation be needed,  turn the knob of the 
thermostat placed under the electronic card on the left side of the machine, remembering that before removing the 
hatch enclosing the electrical parts, it is very important to switch off the current to the machine. 
 
Temperatures advisable for sauces vary from about 65 to 80 degrees Centigrade. 
Lower temperatures favour the growth of bacteria, while at higher temperatures the sauces cook and stick to the 
bottom of the basin. 

 

 

 

 

 

 

 

 
7) READING OF THE PORTIONS SUPPLIED 

To read the number of portions supplied, press yellow buttons 1 and 4 at the same time. 
The figure shown on the display on the left indicates values up to 999, while each LED alight on the yellow and white 
buttons indicate a thousand. 
For example, if the display indicates 452 and two LEDs are alight, then 2,452  portions have been supplied. 
The count goes as far as 8,999 portions, and then is zeroed.
