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
21 Spigot Open Time
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 CODES
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 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 mix
container. 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 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 from
the mix container through a clean and sanitized
sieve or strainer.
In air cooled machines, the Run Time Error may
indicate that airfl ow within the machine has
reduced or stopped. Check the sides and top
of the machine for anything that would restrict
airfl ow.
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
Clean Timer Expired (E4). This condition does not
refl ect a problem with the machine itself. The Clean
Timer Expired message 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 message, press the On/Off
button for the cylinder to turn if off then back on.
