This guide is applicable for F231 gravity-fed floor units.
Error Code: E2 - High Torque
Cause
This error code displays when the controller has sensed the drive motor running for 10 seconds or more at high load. This can be caused by the product consistency adjustment being too high.
Solution
Turn off the cylinder by pressing the On/Off button. Let the product thaw before turning it back on. If the issue is still present after doing this, contact an authorized service agent.
Error Code: E3 - Run Time
Causes
This error code appears when the compressor is running continuously for an extended period of time. This is caused by a few issues like:
- The mix levels are too low in the hopper
- Product breakdown
- Blockage preventing the product from entering the freezing cylinder
- Ice crystals present in the hopper
- Airflow in the unit has reduced or stopped (air-cooled units)
Solutions
In the event an E3 code is present, try these solutions to fix it:
- Check the mix levels in the hopper. If the mix level is low, add more mix.
- If the mix has broken down, or there’s a blockage, clean and sanitize the unit, then replace the mix with new product.
- Check for ice crystals by pouring a small amount of product into a clean sieve or strainer. If ice crystals are present, check and adjust the temperature of your cold storage where the mix is held.
- Check the sides of your unit of any obstructions near air intake ports.
If you’ve completed all of these checks and the error code is still present, contact an authorized service agent.
Error Code: E4 - Clean
Cause
This error code appears when the unit has been left in Clean Mode for longer than 20 minutes.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
Error Code: E5 - Freezing Cylinder Sensor
Cause
The E5 code will appear if there’s a sensor failure or the sensor is out of range.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
If the error code is still present, contact an authorized service agent.
Error Code: E6 - Hopper Sensor
This error code is for single hopper machines, and doesn’t typically occur on units. If it does, contact an authorized service agent.
Error Code: E7 - Drive Motor
Cause
An E7 error code will display if the control doesn’t sense any current coming from the drive motor.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
If the error code is still present, contact an authorized service agent.
Error Code: E8 - Cab Sensor
This error code doesn’t typically occur on units. If it does, contact an authorized service agent.
Error Code: E9 - High Pressure Cutout
Causes
This error code occurs for a few reasons depending on the type of unit you have. In general though, this code will appear if the condenser is dirty or isn’t running as it typically should. Other causes include:
- Air-cooled units: Clogs or blockages around air intakes.
- Water-cooled units: Issues or kinks in the water supply hoses.
Solutions
Various solutions include:
- General: Check the condenser on your unit. Clean as needed, and inspect for any signs of wear or damage.
- Air-cooled units: Ensure there’s proper airflow around the unit and that no blockages are present.
- Water-cooled units: Make sure there are no blockages or kinks in the water supply hoses.
If the error code is still present, contact an authorized service agent.
Error Code: E10 - Auxiliary Sensor
Cause
If an E10 code is present, it’s caused by a failure of the temperature sensor on the control board.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
If the error code is still present, contact an authorized service agent.
Error Code: E11 - Prime Error
This error code doesn’t typically occur on units. If it does, contact an authorized service agent.
Error Code: E12 - Left Hopper Sensor
Cause
This error code displays in the event that there’s a failure of the left hopper sensor, or the sensor is out of range.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
If the error code is still present, contact an authorized service agent.
Error Code: E13 - Right Hopper Sensor
Cause
This error code displays in the event that there’s a failure of the right hopper sensor, or the sensor is out of range.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
If the error code is still present, contact an authorized service agent.
Error Code: E21 - Spigot Open Time
Cause
If this error code appears, it indicates that there’s either a failure of the spigot switch, or the control has sensed that the spigot has been open for 10 minutes or more. This causes the unit to go into Sleep 3 mode.
Solution
Clear the error code by pressing the On/Off button to turn off the cylinder, then turn it back on.
If the error code is still present, contact an authorized service agent.
