What E3
actually means.
The newer Atosa control reads the temperature of the water it freezes. If that sensor is unplugged or open, the board shows E3 and stops. Atosa's steps are to check the sensor connection and then have it serviced.

What to do when E3 shows on the ice machineKind of codeSensors and bin control
A sensor is telling the board something that is not true: a bin control that reads full on an empty bin, or empty while ice spills over the top, a curtain switch stuck open, a temperature sensor out of range, or an eye on a dispenser that no longer sees the cup. Scale and slime on a probe or an ultrasonic sensor cause much of it. Clearing ice piled against the bin control is a safe first step; testing and replacing a sensor is a technician's.

The thermostat bulb, paddle, curtain switch or electronic eye that senses a full bin, adjusted or replaced so the machine stops and restarts on time.
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.

An Atosa ice machine visit opens with the water supply and the air around the condenser, and only then turns to the harvest.

Before you book,
in this order.
Each step comes from Atosa's own guidance for E3 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Switch the machine off and on once to see if E3 returns.
If the machine was just cleaned, mention it at booking, since parts removed for cleaning sit near the sensor wiring.
Book a visit to reconnect or replace the sensor.
Still there?
It usually turns into ice machine bin control repair. Book with the code and the model number.
What not to do
On the display models E3 is not a water shortage, which is E5. The older Y-series manual used the label E3 for other protections, so it does not apply here.

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.
