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
1 Soft
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 Low Temperature
12 Left Hopper Sensor
13 Right Hopper Sensor
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 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 controller has sensed that the drive motor
is running at 125% of the preset CutOut amp
setting 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 and return the switch to the
ON position. 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 20 minutes
without the product reaching consistency in “Serve
Mode” or if the product does not reach proper
temperature in “Sleep 2 Mode”. 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 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". The control will attempt to
restart itself after 5 minutes. The display will then
flash and read Restart. To clear the Clean Error,
turn the Freezing Cylinder Off-On switch Off and
back On. After restarting the machine, a refrigeration
cycle will begin. This protects the product in case
the clean button was pressed by mistake.
