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.

4.2TROUBLESHOOTING

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.
