SECTION 7
TROUBLESHOOTING
7.1 ERROR CODES
When the machine experiences a problem, one of the
following error codes will be displayed on the control panel.
Each error code directs you to the system location of the
malfunction.
ERROR CODE MALFUNCTION
2 High Torque
3 Run Time
4 Clean
5 Freezing Cylinder Sensor
6 Hopper Sensor (single hopper machines)
7 Drive Motor
8 Cab Sensor
9 High Pressure Cutout
10 Ambient Sensor
11 Prime
12 Left Storage Sensor
13 Right Storage Sensor
To return the machine to normal operation, any error
causing condition must be corrected and the freezing
cylinder must be turned off and on again using the On/Off
Left or On/Off Right button.
7.2 TROUBLESHOOTING
ERROR CODE 2 - HIGH TORQUE
If the control panel displays a High Torque Error
(E2), the drive motor is running at a high load for 10
or more seconds. Very low and/or fluctuating
supply voltages typically cause this error. The
error can also be caused by faulty motor or starting
components which could produce a high amp
draw.
ERROR CODE 3 - RUN TIME
The Run Time Error (E3) occurs when the
compressor runs continuously for an extended
period. This error could happen if the cutout
parameter is not attained. This error is generally
caused by very low mix levels in the hopper or from
product breakdown. Another common cause
results from a restriction preventing mix from
entering the freezing cylinder. Check the mix on
the affected freezing cylinder. If the level mix is low,
add mix. If there is a possibility that the mix is
broken down, clean and sanitize the machine and
replace the mix with fresh product.
Ice crystals in the hopper can clog the mix inlet
regulator and prevent mix from entering the freezing
cylinder. Thoroughly thaw mix per manufacturer's
recommendations. To check for ice crystals, pour
a small amount of product from the hopper through
a clean and sanitized sieve or strainer. If ice
crystals are in the mix, check the temperature of
the walk-in cooler where the mix is stored or the
temperature of the machine’s hopper. If the hopper
is below 34°F (1°C), adjust the temperature by
raising the Storage Cutout value in the Storage
Settings menu.
The Run Time Error may also occur if airflow within
the machine has reduced or stopped. Check the
sides and top of the machine for anything that
would restrict airflow. Check the condenser filter
and clean if necessary. Check the evaporator for
frost that could restrict airflow.
The compressor will run continuously if a solenoid
valve fails to open. This could be due to loose
wiring, magnetic coil failure, a stuck valve or a
faulty control board.
After the cause of the problem is found and
remedied press the On/Off button for the cylinder
to turn it off then back on.
ERROR CODE 4 - CLEAN
If the machine is left in the Clean Mode for more
than 20 minutes, the control panel will display a
Clean Error (04). This condition does not reflect a
problem with the machine itself. The Clean Error
has been programmed into the controller as a
safeguard to protect the machine from potential
damage caused by the machine being accidentally
left in "Clean Mode". To clear the Clean Error,
press the On/Off button for the cylinder to turn it off
then back on.
