SECTION 5
TROUBLESHOOTING
5.1 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 Auxiliary Sensor
11 Prime (cab units only)
12 Left Hopper Sensor
13 Right Hopper Sensor
To return the machine to normal operation, any error
causing condition must be corrected and the power to the
affected freezing cylinder must be cycled. Turn the power
to the freezing cylinder off then back on using the On/Off
button of the affected freezing cylinder.
5.2 TROUBLESHOOTING
Error Code 2 - High Torque
If the control panel displays a High Torque Error
(E2), the controller has sensed that the drive motor
is running at a high load for 10 or more seconds.
This may be due to the product consistency
adjustment being set too high. Press the On/Off
button for the cylinder to turn it off, wait until the
product in the freezing cylinder thaws and then turn
the cylinder back on. Follow the instructions in
Section 3 to reduce the product consistency by a
few levels. If the error persists, contact your
Authorized Stoelting Distributor for further
assistance.
Error Code 3 - Run Time
The Run Time Error (E3) occurs when the
compressor runs continuously for an extended
period. 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 in the hopper. If the level mix is low,
add mix. If there is a possibility that the mix has
broken down, clean and sanitize the machine and
replace the mix with fresh product.
Ice crystals in the hopper can clog the mix inlet
system 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 mix container
through a clean and sanitized sieve or strainer. If
ice crystals are in the mix, check temperature of
the walk-in cooler where the mix is stored.
In air cooled machines, the Run Time Error may
indicate that airflow within the machine has reduced
or stopped. Check the sides and top of the machine
for anything that would restrict airflow.
If the error persists after attempting to clear it,
contact your Authorized Stoelting Distributor for
further assistance.
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 (E4). 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 if off
then back on.
