What Er03
actually means.
Er03 is the earlier check of the same evaporator temperature that Er01 watches at 30 minutes. Viking's table gives both the same actions: a refrigerant leak check, a look at the sensor and its attachment, and a restart once cooling is restored.

What to do when Er03 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.
Usually leads toIce 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 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 Er03 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Note how the Ice lamp blinks: a steady one-second blink with the mode switch on cleaning is the wash cycle, not Er03.
Clear the front grille and make sure the room is within the manual's range.
If the Ice lamp keeps blinking in normal icemaking, turn the machine off and book a visit.
Still there?

What not to do
A blinking Ice lamp alone has two harmless meanings on this model as well: the wash cycle and a full bin. Er03 is the one that appears during normal icemaking and does not clear as ice is removed.

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.
