Why You Shouldn't Try to Fix Event Log Error Codes
Do not try and reset the ice machine or fix the issue yourself. A Manitowoc commercial ice maker is a complicated piece of machinery and you could risk damaging the unit. Instead, just make a note of the error codes presenting in the event log.

How to Handle a Temperature Sensor Issue, Liquid Line Temperature Drops, and Other Defects
These errors show up in the event log in connection with issues like low production, a defective USB drive, a faulty freeze cycle, or a temperature outside the appropriate range. Some seem obvious to anyone, such as the USB download error-related messages. While obscure issues like compressor discharge temperature malfunctions or a bin level probe seem more obviously intimidating, it's ultimately best to leave either issue alone.
It's stressful when ice machines aren't working how they should, but messing with the control board usually brings more harm than good. Leave the device plugged in and reach out to an expert to resolve your issue.
What to Do If You See a Manitowoc Error Code
If you see one of these Manitowoc ice machine light codes in the event log, it's best to call a qualified ice machine technician—especially if you notice performance issues with your ice machine. A single error code can have many root causes, and an ice machine technician will have to run a series of tests to see what’s causing the issue.
That being said, there are some common freeze cycle issues or ice thickness probe problems you could fix on your own. If you'd like to see what you can do, we've put together this Manitowoc ice machine troubleshooting guide as a helpful resource.
