U-Line UONB115 Showing E13: Nugget Ice Auger Error Explained
E13 on a U-Line nugget ice machine tells you the control found an error with the auger, so nugget production slows or stops. It applies to nugget machines like the UONB115 and UHNP315 only, never to clear ice machines.
What does U-Line ice machine code E13 mean?
Among U-Line nugget ice machines, the UONB115 and UHNP315 display E13 when the control notices a problem with the auger. The auger is the part that carries ice nuggets through the machine toward the bin. While the code is on the display, nugget production slows or stops until the error clears. Clear ice machines do not use this code, so it belongs to the nugget line only. The message points to the auger area, and the exact cause needs testing before anyone names a part.

How the ice machine detects E13
A nugget ice machine forms small nuggets of ice and relies on an auger to push them along toward the bin. The control keeps an eye on that auger drive while the machine runs, and it expects the drive to behave the way it should whenever ice is being made.
When the control sees something it does not expect, such as resistance from packed ice or a drive circuit that does not respond properly, it raises E13. Production slows or stops at that point so the machine does not keep pushing against a problem. The code names the auger area, but the control cannot say by itself whether ice, debris or the drive is behind it.
Likely causes of E13
- The auger drive is not turning the way the control expects
- Ice or debris is jamming or restricting the auger
- A condition in the auger drive circuit that the control picks up
Can you keep using the ice machine with E13?
Nugget production slows or stops with E13 on the display, so there is little to gain from running the machine. Switching it off for ten minutes is safe, but do not put a hand into the machine or down the ice chute to look for the cause. If the code returns after a restart, leave the machine switched off and let a technician look at the auger area.
What you can safely check
- Switch the machine off at its power control or unplug it, and wait ten minutes before touching anything.
- Look into the bin from the front and see whether ice has packed up or jammed.
- Plug it in or switch it on again and watch the display.
- Keep your hands out of the machine and the ice chute at all times.
- If E13 returns, leave the machine off and call us.
What our technician does for E13
- Check whether the auger turns freely and without resistance
- Test the auger drive and its circuit
- Clear any ice or debris restricting the auger, then replace the failed part once testing names it
How to keep E13 from coming back
- Clear packed or clumped ice out of the bin, working only from the front opening.
- Keep the area around the machine free of items that could fall into the ice chute.
- After any jam, switch the machine off and wait before restarting rather than restarting repeatedly.

E13 questions
Does E13 mean the ice machine is ruined?
No. E13 means the control found an error in the part that moves nugget ice through the machine. The cause has to be traced before anyone can say whether a part has failed.
Will a clear ice machine ever show E13?
No. Clear ice machines use a different set of codes, so check the model label to see which type you own. E13 is shown by nugget machines, for example the UONB115 and UHNP315.
Why does ice output drop when E13 appears?
The control holds back production because it cannot trust the auger to move ice. Output may be slower or stop entirely until the error is cleared.
Will E13 clear by itself after a rest?
Restarting after a rest can clear the display for a while. If the cause is still present, the control raises the code again. A code that keeps coming back means the auger area needs testing.
What should I tell the technician about E13?
Give us the model, for example a UONB115 or UHNP315, and say that E13 is showing. Mention whether the code appeared right after a restart and whether the bin was packed with ice.
