TROUBLESHOOTING

4.1 ERROR CODES

When the freezer 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.

To return the freezer to normal operation, any error caus-
ing 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 freezer
will return to normal operation.

4.2 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 freezer 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 barrel thaws to a reasonably soft consistency
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 30 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
freezer’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 is
broken down, clean and sanitize the freezer 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 in the hopper 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 freezer’s cabinet.

The Run Time Error may also occur if airflow
within the freezer has reduced or stopped. Check
the sides and top of the freezer 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 freezer 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 freezer itself. The Clean
Error has been programmed into the controller as
a safeguard to protect the freezer from potential
damage caused by the freezer 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 the Clean Error has been cleared, the freezer
will start a refrigeration cycle to protect the product
in case the clean button was pressed by mistake.
