SECTION 4
TROUBLESHOOTING
4.1 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
12 Hopper Sensor
13 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 posi-
tion and back in the ON position before the machine will
return to normal operation.
4.2 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. Place the Freezing Cylinder Off/
On switch in the OFF position, wait until the product
in the barrel thaws to a reasonably soft consistency
and return the switch to the ON position. 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 could happen if the cutout
value is not attained during “Standby Mode” or if
the “Ready” signal does not come on in “Custard
Mode” or “Italian Ice Mode”.
This error is generally caused by very low mix
levels in the hopper or from product breakdown.
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.
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 10 minutes, the control panel will display a
Clean Error (E4). This condition does not refl ect 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
fl ash and read Restart. To immediately clear the
Clean Error, place the Freezing Cylinder Off/On
switch in the OFF position and back in the ON
position. After the Clean Error has been cleared,
the machine will start a refrigeration cycle to
protect the product in case the clean button was
pressed by mistake.
