U-Line ice maker display · also shown as ICE, NO WATER and DRAIN lamps lit What to do when Er25 shows on the ice maker ### Kind of code Ice making and harvest The ice maker froze a batch and could not release it, or the harvest never started: the ejector arm or the twisting tray stalled, the mold heater did not loosen the cubes, or the arm that senses a full bin reported the wrong thing. Ice jammed against the arm and a bin pushed in crooked are cleared first; a motor module or a whole ice maker assembly comes after. ### Usually leads to Ice maker assembly replacement A new ice maker module fitted in the freezer compartment or the door compartment, after the water, the temperature and the bin sensor have been proved good, so the new part is not blamed for an old problem. ### Shows up as Nugget Ice Maker Not Making Nugget Ice A nugget ice maker not making ice runs and hums but drops nothing, makes wet slush instead of crisp pellets, or stops after a few batches with a light on. ### Make U-Line U-Line undercounter ice maker service, including cleaning, descaling and drain repair. ### Source U-Line User Guide & Service Manual, URNP115 nugget ice model (u-line.com PDF) U-Line URNP115 15-inch nugget ice model. ## Before you book, in this order.

Check the temperature where the unit is installed; it needs to be above 50°F. If it comes back, it needs a visit. ### Why are all three lamps lit steady on my U-Line nugget ice maker? That pattern is Er25: the evaporator got colder than -7.6°F. It usually happens when the unit sits in a cold room, garage or basement. ### What room temperature does a U-Line nugget ice maker need? The troubleshooting table says to run it when the ambient temperature is over 50°F. ### Can Er25 on a U-Line damage the ice maker? Running an evaporator that cold can freeze water where it should flow. Let the room warm up before restarting, and book a visit if the code repeats in normal conditions. --- **[Read on the site: U-Line nugget model all lamps lit steady (Er25): evaporator too cold](https://icemakerrepair.center/error-codes/u-line-er25/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
