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 

  

Soft

  

High

 3

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 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 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 to a reasonably soft 
consistency and return the Main Power switch to 
the ON position. Follow the steps in section 3 to 
reduce product consistency by a few levels. If the 
error persists, contact your authorized Stoelting 
Distributor for further assistance.

SECTION 5

TROUBLESHOOTING

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 cabinet. If 
the level mix is low, add mix. If there is a possibility 
that the mix is broken down, clean and sanitize the 
machine and replace the mix with fresh product. 

 

Ice crystals in the liquid 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 in the 
mix container 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 machine’s 
cabinet.

 

Check the condition of the neoprene hose running 
through the mix pump head. If it shows signs of 
wear, rotate or replace it as outlined in Section 
3.

 

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 a 
Clean Error (Error 04). 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 Main Power Off-On switch 
in the Off position and back in the On position. 
After restarting the machine, a refrigeration cycle  
will begin. This protects the product in case the 
clean button was pressed by mistake.
