U-Line Outdoor Nugget Ice Maker Code 11: Water Level High

What 11 means

On U-Line Outdoor Collection nugget ice makers such as the UONB115 and UONP115, the display shows 11 when the water level is high. The reservoir holds more water than the control expects, and ice is not being made fast enough to use it. The panel prints the number alone. You see 11 on the display while ice output lags behind.

Common causes of 11

Water level in the reservoir reads high
Ice making is slower than the water supply
The level reading does not match the reservoir

✓ One safe check you can try

1. Check that the unit sits level on its pad. 2. Clear the bin opening of debris or packed ice. 3. Switch the machine off for a few minutes and back on. 4. Look at the supply line for a pinch or a loose fitting. 5. If 11 returns, call us.

! Why to stop there

High water on an outdoor unit can come from the supply or from the ice side, and we test both
Freezing weather turns standing water into damage
You get the price in writing first, and a 30-day warranty follows the work

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.

1111 questions

What does 11 mean outdoors?

It means the control reads the reservoir water level as high. The unit is not making ice quickly enough, so water builds up and the display shows 11.

Is 11 the opposite of 12?

Yes. 12 reports low water on the same models, while 11 reports high water. Seeing 11 tells us to look at why the reservoir is staying full.

Does cold weather affect 11?

Outdoor units are exposed to temperature swings, and slow ice making is one reason water lingers. We check the water level reading and the ice cycle together when you book.
