What Er01
actually means.
Once ice making starts, the evaporator should drop well below freezing. If it is still at 32°F or above after 30 minutes, the control blinks ICE, NO WATER and DRAIN together and records Er01. U-Line's service steps include a refrigerant leak check and a sensor check, so this is a sealed-system question.

What to do when Er01 shows on the ice machineKind of codeCooling 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.

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 asIce 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.

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.

Before you book,
in this order.
Each step comes from U-Line's own guidance for Er01 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Turn the machine off and check that the condenser grille at the front is not blocked.
Make sure the room is within the range the guide allows for the model.
Book a visit; U-Line asks for power to be restored only after the cooling problem is solved, and a leak check on R-290 is a technician's job.

What not to do
Er01 is the 30-minute check; Er03, with only the ICE lamp blinking, is a similar warm-evaporator check made at 10 minutes. All three lamps lit steady, not blinking, is Er25, the opposite problem of an evaporator that got too cold.

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
