Symptons P11 - The motor has stopped and the cold telltale light is off.
Problem
The tank does not get cold and the augers do not turn.
Cause1
The aluminium disk is warped and touches the optical reader, thus jamming the gearmotor (for 115V 60 Hz, or 230V
60 Hz slush machines, even if the disk has only moved close to the reader, it can jam the gearmotor).
Solution1
If possible, straighten out the disk (pos. 56) using a pair of pliers (o). If it needs replacing, the optical reader (58)
must be removed: unscrew the cross- slotted screws (pos. 57) with screwdriver (l). When the reader has been

Pag. 13/26
Cause2
The four contacts (pos. 15-16) lodged on the terminal board (pos. 37) are not well touching the terminal board itself.
Solution2
Restore the 1st contact (facing the back of the tank, counting from the left, there are the 1 st , 2 nd , 3 rd and 4 th
contacts). Remove the top light cover, lifting it from the back, then unscrew the knobs (pos. 50) - if presents -,
unscrew and extract the sleeve (pos. 1), release the hook (pos. 48) by pulling the front hinge lever (pos. 49), and
extract the tank (pos. 14). Facing the tank from the contact side (pos. 15), pull the bottom part of the contact
outwards with the pliers (o), so as to restore the contact near the terminal board (pos. 37). Then repeat all the above
operations in the reverse order to reassemble all the parts, and check to see if everything works properly.
NOTE: From January 2001 was introduced a new function in the electronic board (rev. 07A) called "bypass". This
system permits to resolve temporarily - by phone - contacts problems (as illustrated in Solution2).
The procedure is:
1. press the key selection slush-juice till augers turn (pay attention: this system disac tive the safet y syst e m
and the "lock out keyboard");
2. if the augers starts again, there is a malfunction of the conta ct 1 or of the conta ct 2 (see Solution2), to which it has
been made up for with an electronic bypass. The bypass remains active also following turning off and on of the slush
machine.
Once replaced the defective contact, or insta lle d the lost co ntac t, in order to eliminate the electronic bypass realized
previously, must be used the following procedure:
• up the lid;
• stop the augers pressing the key ;
• holding pressed the , press the augers key to have the augers left again;
• Wait until the augers are stopped and release the keys;
• put the cover on the tank;
• the augers leaves again, and the electronic by pass ha s been e lim ina ted.
Warning: you always have to check the right position of the contacts, especially of the refill contact (the long probe
which touches the liquid): if you look the tank from behind and star t to count from the left, this contact must be at the
third place. The slush machine may not work properly if you do not place this contact in its right place.

P21 - Product leaks from the dispensing spout.
Problem
Constant dripping of product.
Cause1
If the product drips from below the dispensing spout, the O- ring (pos. 6) is worn or the spring on the spout is
improperly positioned. If it drips f rom behind the spout, the valve gasket (pos. 9) is worn.

Solution1
Empty out the tank, stop the augers by turning off the switch at bottom right of the module (pos. 73), open the valve
by pulling
the lever (pos. 3) all the way, move the lever on the ring nut (pos. 11) to the right so as to lock the valve open, then
pull out
the cover on the lever (pos. 4). Rotate the piston 180° to make sure that the sp ring is pos itione d prop er ly in its sea t .
Holding the
lever (pos. 3) down in the open position, move the lever on the ring nut (pos. 11) to the left so as to release the
valve. Then
unscrew the ring nut (pos. 11), turning it to the left with the he lp of the lever, and ext rac t the en tire d isp enser unit
along with
the lever. Using the screwdriver (f), pry out the seal to be replaced and remove it from the piston assembly (g).
Repeat the above operations in the reverse order to reas se m ble a ll the pa rts.

P22 - In cold drink mode the freezing is never active or freezes too much.
Problem
The cooling function of a tank seems to be incorrect as the tank does not freeze enough or it cools too much forming
an ice block and stopping the auger.
Cause1
This problem is generally caused by the thermostat probe which is wrongly placed or defective.
Solution1
You need a tester and a new probe (or anyway a correctly working one), to check if the installed probe is defective.
Proceed as follows:
1. disconnect the machine by the electrical plant;
2. remove the lateral panel and, if you need a better view to operate correctly in the machine, remove also
the back panel;
3. following the white wire which starts from the electronic board and finishes under the tank, please find the
probe;
4. disconnect the white wire from the electronic board;
5. right where the wire finishes, under the tank, there is a hole where the termostat probe is inserted in; you
will find it fixed in with a steel bushing or a little gum block;
6. if you have found the steel bushing, please remove it with a plain screwdriver; if you have found the little
gum block remove it rotating it gently; after this procedure, remove the probe gently pulling the white wire
down;
7. clean the probe from the conducting paste and put it in a glass of water with a certain tempera tu re
together with the probe which works perfectly;
8. place the tester pins inside the two ways ending pin of the probe's wire;
9. record the value of the resistance indicate d by the tes ter ;
10. check the value of the resistance indicated by the tester on the other probe;
11. if the values are different (difference of many tens of Ohm) this means that the probe is really defective.

COTTER PIN REPLACEMENT
What to do when the cotter pin is broken
1. When the machine is working it might happen that the electronic device works perfect ly
(freezing light indicator and switches in function, see Picture 01) but the augers don’t
turn around. This is possible because of a broken cotter pin (split pin) which co nnects
the gear motor to the transmission shaft and allows the movement of the augers.
2. Remove the back and lateral stainless steel panels and you will be able to understand
what is wrong with the slush machine trying to lift the ring nut of the blocked vertical
auger out of the tank. The ring nut will not raise (as s hown in Picture 02) or it raises
together with the transmiss ion shaft (see Picture 03).
Pag. 24/26
3. In the first case you should check the base of the shaft inside the machine next to the
gear motor (output shaft). The cotter pin is still inside the hole of the gear motor (as
shown in Picture 04) but it is slackened and deformed; the blue arrow indicates the
cotter pin, the red one shows how the cotter pin has lost its original shape and the green
dotted line shows its right placement.
4. In the second case the hole of the gear motor (see Picture 05) should be completely empty and
the remaining of the broken cotter pin will certainly be on the base insi de the machine (as the red
circle shows in Picture 06).
5.
You must replace the old cotter pin with a new one; place the transmission shaft and
remember to align the hole of the transmission shaft with the hole of the output shaf t; if
you watch through the holes you should be able to see the other side; insert the new
cotter pin as shown in Picture 07. Remember to keep some space between the head of
the cotter pin and the gear motor so the former cannot touch the latter during its
rotation; respect a little distance between the two components as shown by the arrows in
Picture 08.
Pag. 25/26
6. Fold the ends of the cotter pin with pliers as shown by the blue arrows in Picture 09; cut the
exceeding legs of the cotter pin with nippers to avoid the contact with the gear motor during the
rotation (see Picture 10).
7. The final result is shown in Picture 11.
