What E9 means

On U-Line Outdoor Collection nugget ice makers such as the UONB115 and UONP115, E9 reports that Door 1 is open. The control has not seen the first door in its closed position, so ice production pauses and the display holds E9. It clears once the door closes and is sensed.

Common causes of E9

  • Door 1 was left ajar
  • Something holds the door edge away from the cabinet
  • The gasket is out of position
  • The first door switch is not reporting closed
✓ One safe check you can try

1. Close Door 1 firmly and listen for the latch. 2. Clear anything resting against the door edge, such as a cover or a bag. 3. Wipe the gasket and check that it lies flat. 4. Confirm the unit sits level on its pad. 5. If E9 stays on with the door shut, call us.

! Why to stop there
  • Outdoor units collect grit and moisture where the switch sits, and cleaning it correctly takes the right tools
  • Ice in the bin melts quickly while the door fails to seal
  • We quote before we start and warrant the work for 30 days
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.

E9E9 questions
What does E9 mean on my outdoor ice maker?

E9 means the control reads Door 1 as open. Ice making pauses until the door is closed and sensed, and the code clears on its own at that point.

Where is the code for the second door?

Door 2 is reported as 10 on these Outdoor Collection nugget models. Together, E9 and 10 tell you which door the control sees open.

Why does E9 return after I close the door?

If the door is shut and E9 persists, the switch or the gasket fit is not letting the control confirm a closed door. We check the door switch first and then the seal.
