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
1 Soft
2 High Torque
3 Extended Run Time
4 Clean
5 Barrel Sensor
6 Hopper Sensor
7 Drive Motor
8 Cab Sensor
9 High Pressure Cutout
10 Auxiliary Sensor
11 Low Temperature
To return the machine to normal operation, any error
causing condition must be corrected and the Freezing
Cylinder Off-On switch must be placed in the Off position
and back in the On position before the affected side of the
machine will return to normal operation.
5.2 TROUBLESHOOTING - ERROR CODES
Error Code 1 - Soft Error
The Soft Error (E1) is an internal control board
error that is logged for future analysis. The
refrigeration is never stopped and the machine
will continue to operate normally.
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. This may be due to the
product consistency adjustment being set too
high. Place the Main Power OFF/ON switch in the
OFF position, wait until the product in the freezing
cylinder thaws to a reasonably soft consistency
and return the Main Power switch to the ON
position. Follow the steps in section 3 to reduce
product consistency by a few levels. If the error
persists, contact your authorized Stoelting
Distributor for further assistance.
SECTION 5
TROUBLESHOOTING
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 machine’s mix container or from
product breakdown. Another common cause
results from a restriction preventing mix from
entering the freezing cylinder. Check the mix in
the cabinet. 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 liquid mix container 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 in the
mix container 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 cabinet.
Check the condition of the neoprene hose running
through the mix pump head. If it shows signs of
wear, rotate or replace it as outlined in Section 3.
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 (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”. The control
will attempt to restart itself after 5 minutes. The
display will then flash and read Restart. To
immediately clear the Clean Error, place the Main
Power Off-On switch in the Off position and back
in the On position. After restarting the machine, a
refrigeration cycle will begin. This protects the
product in case the clean button was pressed by
mistake.
