P01 – Machine does not freeze and red light located near
the main power switch (pos.72) is ON
Problem
High pressure switch cut off compressor (pos.87).
93
Reason_1
Condenser/Condenser air filter is dirty (pos.95).
Solution_1
Clean the condenser/condenser air filter with a brush (a) or compressed air and them reset the
compressor by pressing high pressure switch down (pos.93). ATTENTION: machine has to be
ON in order to reset the compressor.
Reason_2
Airflow around the machine is insufficient due to either other piece of equipment blowing hot
air into the machine or insufficient space (recommended approximately 12 cm – 5 inches on
each side).

Solution_2
Establish required space around the machine and reset the compressor by pressing down high
pressure switch (pos.93)
Reason_3
Condenser fan motor does not turn (pos.99).
Solution_3
Verify whether fan motor’s blades are not blocked by the condenser or a loose wire.
Verify whether fan motor is burned. If so, replace fan motor: 1. unplug the wires and remove
screws from the base of the machine (pos. 104); 2. Remove screw, which holds the fan motor
blades; 3. Install new fan motor and blade; 4. turn the machine back ON; 5. verify if fan motor
is turning and cooling the machine; 6. reset the high pressure switch (pos.93)

P02 – Machine does not freeze even though the solenoid
valve is ON (solenoid light located on the screen is ON;
high pressure red light remains OFF - pos.72)
Problem
Refrigerant does not pass through into the evaporator.
Reason_1
Electrical coil or coil’s fuse is burned.
Solution_1
Replace the 315mA fuse (pos.90), located in a fuse holder near the coil; if this does not help,
replace the coil.
Reason_2
Solenoid body valve (pos.91) is defective: remains closed even through it is commanded by
the control board to open (“click sound” coming out of the coil).
Solution_2
Replace the entire defective solenoid body valve (pos.91).
Reason_3
There is a false contact in fuse holder.
Solution_3
Restore the proper contact by between wires and a fuse in a fuse holder
Reason_4
Control board (pos.73) is defective and does send the signal to the electrical coil to open. It
has to be verified with electric tester (r).

degrees F; Turn the machine back ON; set to SLUSH mode; auto calibration process begins
(WAIT AUTO SETTING comes on the control board’s screen in place of SLUSH); After approx.
30 seconds calibration process ends and machine goes into SLUSH mode.

P04 – Control board’s screen is blinking; when MENU
button pressed and released, "ALARM MOTOR" comes on
the screen; mixing augers turn
Problem
Machine does not freeze.
Reason_1
Magnetic Reader (Hall Cell) attached to the gear box is broken (pos. 124).
Solution_1
Replace the Magnetic Reader: disconnect the magnetic reader wire (pos. 121); remove the
magnetic reader’s black plastic cover (pos.124) with small flat screw driver (f) – pay attention
to 3 little hooks that hold the reader attached to the gear box; Install the Magnetic Reader –
follow the above instructions in reverse.
Reason_2
Magnet located on a short shaft of the gear motor (underneath the Magnetic Reader (pos.
123)) has been dislocated.
Solution_2
After removing the Magnetic Reader and gaining access to the magnet and sleeve (pos. 122 &
123), reposition the magnet on the gear motor’s shaft: it should be positioned exactly half way
