Check the drain hose for kinks, sags or a clog, and make sure the drain it runs to is clear. If it comes back, it needs a visit. ### What causes the DRAIN lamp to blink on a U-Line nugget ice maker? Water in the reservoir did not fall to the low level within two minutes of the drain valve opening. A blocked or kinked drain line is the first thing to check. ### Can Er16 on a U-Line nugget unit cause a leak? Water that cannot drain has to go somewhere, so check the bin and the floor. If water is escaping, close the supply valve while you wait for service. ### Is the drain valve or the sensor to blame for Er16 on a U-Line? Either can be. U-Line lists replacing the water level sensor and checking the drain valve, which a technician tells apart by testing both. --- **[Read on the site: U-Line nugget model DRAIN lamp blinking (Er16)](https://icemakerrepair.center/error-codes/u-line-er16/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
