Make sure the water shutoff to the unit is fully open and the supply line is not kinked. If it comes back, it needs a visit. ### What makes a U-Line outdoor ice maker show 12? Anything that keeps water from reaching the reservoir: a closed or partly closed valve, a kinked or frozen line, or a fill valve that does not open. ### Will my U-Line keep making ice with 12 on the display? Not reliably. With a low water level, the evaporator does not get a full flow, so production drops or stops. ### Is 12 on a U-Line the same as 11? No. 11 is a high water level and can mean an overflow; 12 is a low level and means too little water. --- **[Read on the site: U-Line E12 (shown as 12): water level too low](https://icemakerrepair.center/error-codes/u-line-e12/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
