Hopper & barrel temperature

I am assuming that it is the left side that is freezing up? Is there a large disparity in temperature from the left side to the right? Your machine monitors the temperature on the right side hopper and that will determine the temp of both sides. If there is a large temperature difference between the two sides then it may be that you are low on refrigerant. You may have enough refrigerant to cool the left side but not the right side and since the machine only monitors the right side, it wont shut off the mix refrigeration system which could cause the left side to freeze up.

Certain conditions must be met. The machine needs to be empty. The freezer door must be off the machine. The power switch must be off. Once the machine is off, a 5 minute countdown will show. It will also show 4 temperature readings. All 4 of them must be above 60 degrees F. before the countdown will start. Once the counter reaches zero, the Brush Clean Cycle will be reset along with any temperature vs. time error codes. If at any time, one of the temp readings drop below 60 degrees F. before the end of the 5 minute countdown, the countdown will reset to 5 minutes and the machine will not reset. Generally, the freezing cylinders take longer to come to temperature. Even when you run warm water through it first, there is sometimes enough residual cold to bring the temperature back below 60. A successful Brush clean Cycle will display "Power Switch Off---Unit Cleaned" and the 2 digit green display under the main display will reset to 00. if this happens and you turn the machine back on and you are hit with the same message then you may have an issue with one of your boards.

That code means the right side hopper thermistor probe has failed. That is the sensor that reads the temperature of product in the mix hopper.

This is the part you need:

If you order it from us, I would be happy to put a technician on the phone to help you install it yourself.

Empty the machine, clean it out. Remove the freezer door assembly, shut the machine off. it should display a 5 minute timer and 4 temp readings. All 4 of the temp readings need to be above 60 degrees F. for the counter to start. Once it reaches zero, the machine will reset and you should be good to go. If successful the machine will display "Power Switch Off---Unit Cleaned". if at any point during the 5 minute countdown, one of the temp readings drops below 60, the countdown will reset to 5 minutes and the machine will stay freezer locked.

The temperature of the product is too high. If the product either in the cylinders or the hopper goes above safe temperature for too long the freezer will lock until the product is removed and the unit is properly cleaned. I would guess it's the hopper temperature because I think you would notice if the product that's dispensed is above 40 degrees. Soft Serve Parts C713

If it is the lower display with the 2 green digits, then that is referring to hours of service since last brush clean cycle. It is just a timer. Once it reaches 99, it start to use letters and numbers, so A1 would be 101 hours since last brush clean. b1 would be 111 hours and so on. To clear this the machine must recognize a brush clean cycle. the next time you clean your freezer door, make sure the power switch is off. it will display a 5 minute timer and 4 temperature readings. All 4 of those temperature readings must be above 60 degrees Fahrenheit and remain above 60 for 5 minutes. If at any point the temps drop below 60, the timer will reset. The freezer door must remain off the machine during this time. Once the timer reaches 0, the machine will enter a Unit Cleaned state and you can reassemble the machine.

Under normal operating conditions, the C712 will enter freezer lock when the temperature of the barrels or hoppers have been above 41 degrees for too long. It requires you to do a cleaning cycle. You will have to empty the machine of product, rinse it out, remove the freezer door, and shut the machine off. once the machine is off you will see a 5 minute timer and 4 temperature readings. That timer wont start unless all 4 temperature reading are above 60 degrees F. once the timer reaches zero, the machine will unlock and your brush cycle timer will reset to 00. The brush cycle timer is underneath your main display. Your main display should now show "Power Switch Off--- Unit Cleaned" and you can now reassemble your machine and can use it.
Some causes:

Low product with a lid off.

During a cleaning cycle, the barrels take longer to come up to temperature than the hoppers. Its entirely possible to thoroughly and properly clean the machine without satisfying the temperature requirements. The machine doesn't register the cleaning cycle and you reassemble the machine. The machine doesn't know you cleaned the machine so it was still keeping track of how long the temperatures were above 41 degrees and as soon you try to put it in auto or standby, it goes into a freezer locked condition.

One of the probes may be failing. You can check this by going into "Current Conditions" in your managers menu. You'll see the 4 temperature readings and if one of them is a lot higher or lower than the actual temperature of the product that could be an indicator of a failing temperature probe.

Sounds like your mix compressor is bad or freon leak on the mix

Barrels and hoppers above 50 degrees, both empty, machine switched off and door off for the 5 minute timer, during which you should be cleaning the unit properly after the timer has reached 0 it will reset for 14 if your freezer locking everyday there is something wrong with your unit and needs to be looked at.
