P08 - Number "8" flashes on the display.

Problem

Voltage fluctuations exceed 10%. This, in the long run, can damage the slush machine.

Cause1

Defective mains power supply, multiple sockets, inadequate extension cords, etc.

Solution1

Make sure that the slush machine receives the proper voltage. Reset the system by holding down the light switch located bottom left on the electronic module, until number "8" stops flashing. If the flashing "8" appears again this means that the voltage is still wrong; if so turn off the top lights so that the absorbed voltage will become lower; this will let the slush machine work again until the voltage will be restored.

Note: if the slush machine has switched on the autofill system, the slush machine must be switched off completely

(through the main switch) in order to reset the system.

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

and the "lock out keyboard"); till augers turn (pay attention: this system disactive the safety system

2. if the augers starts again, there is a malfunction of the contact 1 or of the contact 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 installed the lost contact, 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 bypass has been eliminated.

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 start 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.

Then unscrew the ring nut (pos. 11), turning it to the left with the help of the lever, and extract the entire dispenser 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 reassemble all the parts.

Symptons

FC - First Class GB

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 temperature 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 indicated by the tester;

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 perfectly

(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 connects 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 shown in Picture 02) or it raises together with the transmission shaft (see Picture 03).

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 inside 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 shaft; 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.

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.
