Er25 is a too-cold warning. U-Line ties it to a low room temperature and asks for the machine to be run where the air is above 50°F. It is most often seen on outdoor and garage installations in cold weather. U-Line ice machine display · also shown as ICE, NO WATER and DRAIN lamps lit What to do when Er25 shows on the ice machine ### Kind of code Cooling system The board saw temperatures or pressures that the sealed system should never reach: a discharge line too hot, a suction side that never cools, or a compressor that starts and stops on its overload. A dirty condenser can push a healthy system into this family, so it is the first thing to rule out; a low charge, a leak or a tired compressor is not. On many current machines that system holds R-290, which is flammable, and only a technician opens it. ### Usually leads to Ice machine compressor and sealed system repair The compressor, its start parts and the sealed system, including machines on flammable R-290, tested for pressure and leaks and repaired by the maker's procedure. ### Shows up as Ice Machine Error Code or Flashing Light: What It Is Telling You An ice machine error code may show as a number on a small display, a pattern of blinking lights on the control board, a colored light on the front, or a machine that stops with one indicator flashing. ### Make U-Line U-Line ice machine visits in a home bar start at the drain, since a slow line affects both the ice and the floor around it. ### Source U-Line URNP115 15-inch nugget ice machine user guide U-Line 1 Class RNP115 and Outdoor ONP115 nugget ice machines, which report through the ICE, NO WATER and DRAIN lamps beside the light button. ## Before you book, in this order. Each step comes from U-Line's own guidance for Er25 on its ice machines. Follow it to the end: the last card says whether this is a visit. 01 Check the temperature where the machine stands; if it is below 50°F, the machine should not run there until it warms. 02 Once the space is warm enough, turn the machine off and on again. 03 If the lamps come on steady in a warm room, book a visit to check the evaporator sensor. ### Still there? It usually turns into [ice machine compressor and sealed system repair](https://icemachinerepair.center/services/ice-machine-compressor-and-sealed-system-repair/). Book with the code and the model number. ### What not to do Steady lamps are different from blinking ones: all three blinking is Er01, a warm evaporator. A steady DRAIN lamp alone is normal draining. ## What you may notice with it. The ice machine problems Er25 tends to arrive with. Answer these at the ice machine before anyone is booked.

Check the temperature where the machine stands; if it is below 50°F, the machine should not run there until it warms. If it comes back, it needs a visit. ### Why does my outdoor U-Line nugget machine show all lamps lit in winter? Cold air lets the evaporator run too cold, which is Er25. U-Line asks for operation above 50°F. ### Should I winterize my outdoor U-Line nugget machine? If the space will be cold for a season, yes: shut it down and drain it rather than leaving it to run into Er25. ### Is Er25 bad for the machine? The control stops it to protect the evaporator. It needs warmer air, not a part, unless it happens in a warm room. --- **[Read on the site: U-Line nugget ice machine with all three lamps lit steady (Er25)](https://icemachinerepair.center/error-codes/u-line-er25/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
