U-Line Nugget Ice Machine Code 10: Door 2 Open

What E10 means

On U-Line ice machines with two doors, such as the UONB115 and UHNP315, the display shows 10 when Door 2 is open. The panel prints 10 rather than E10. The control has not detected the second door in its closed position, so ice production pauses until that door is closed and sensed. The first door reports as E9, so the two codes tell you which door is open.

Common causes of E10

Door 2 was left ajar
Something holds the door off the cabinet
A gasket is out of place
The Door 2 switch is not reading closed

✓ One safe check you can try

1. Close the second door firmly and check that it latches. 2. Clear anything blocking the door edge. 3. Check that the gasket lies flat along the opening. 4. Make sure the machine is level. 5. Call us if 10 stays on with the door shut.

! Why to stop there

A closed door that reads open is a sensing matter
Waiting lets stored ice melt
Our price comes first and the work carries a 30-day workmanship warranty

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E10E10 questions

Why does my display show 10 and not E10?

The panel shows the number without the letter. The code means Door 2 is open, and the control treats it the same way as the E-numbered door code.

Where is Door 1's code?

Door 1 is reported as E9. Together, E9 and 10 tell you which door the control sees open, so you know which one to close.

Does 10 clear on its own?

It clears when the control detects Door 2 closed. If the door is shut and 10 stays on, the Door 2 switch or gasket fit needs a check from us.
