What Er01
actually means.
The evaporator is where the nugget ice forms, and after half an hour of running it should be well below freezing. If it still reads 32°F or warmer, the control stops and blinks every lamp; Viking's own list starts with a possible refrigerant leak and then the sensor and its mounting.

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.

Before you book,
in this order.
Each step comes from Viking's own guidance for Er01 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Check that the front grille is clear and that the room is not unusually hot, since both slow the cooling.
Turn the machine off and leave it off; restarting it repeatedly will not fix a cooling problem.
Book a visit: the sealed system on this model holds R600a, a flammable refrigerant, and is checked only by a technician.

What not to do
Er01 is not the same as all three lamps lit steady, which is Er25, an evaporator that got too cold. It is also different from Er03, which blinks the Ice lamp alone after 10 minutes.

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.
