What E3
actually means.
During freezing the evaporator should be cold. If the BLMI board reads more than 140 F there, it stops to protect the system and shows E3. Blue Air's list is short: water that is too hot, a sensor or connector problem, or the control board.

What to do when E3 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.

Blue Air ice machine calls start by reading the controls and looking at the evaporator for scale that slows the freeze.

Before you book,
in this order.
Each step comes from Blue Air's own guidance for E3 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Check that the water line is not picking up heat from a hot water pipe or appliance nearby.
Switch the machine off and on once and note whether E3 returns at the next freeze.
If it does, book a visit to test the evaporator sensor and its connector.

What not to do
E3 is not a sensor that is completely disconnected; that is E6. It is also not the same as E1, which is a freeze that took too long.

Blue Air ice machine repair
Modular ice machine
An ice-making head set on top of a separate storage bin or drink dispenser, cooled by air, water or a condenser on the roof, turning out hundreds of pounds of cubes a day.
Undercounter ice machine
A self-contained ice machine that makes and stores its own ice under a bar, a service counter or a kitchen island, from commercial units to clear-ice models in large homes.
Nugget ice machine
An ice machine that freezes a thin layer inside a chilled cylinder and pushes it out with an auger as soft, chewable nuggets, for clinics, offices, hotels and large homes.
In Blue Air's own words
If temperature outside the evaporator during freezing cycles goes over 140°F (60°C), machine stops to protect the cycle and error code (E3) is shown

Can I clear E3 myself?

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.
