What E1
actually means.
The board expects the condenser sensor to warm up while the machine makes ice. If the sensor is unplugged or its reading does not move, the board stops with E1. Atosa lists the sensor connection first and the cooling system second, because a system that is not running also leaves the reading flat.

What to do when E1 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 E1 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Switch the machine off and back on once and note whether E1 returns.
Make sure the condenser fan area is clear and the machine is getting air.
Book a visit; the probe connection sits behind panels and the cooling system check needs a technician.

What not to do
On the display models E1 is not a long freeze cycle, which is what the older Y-series LED board used the label E1 for. It is also not E4, which is a condenser that is too hot rather than a sensor that is silent.

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.
Ice and water dispenser
A countertop or floor-standing unit in a hotel hallway, an office or a clinic that makes and stores ice and hands it out with water at the touch of a lever, a button or a sensor.

Questions
about E1.
Can I clear E1 myself?
Is E1 on my new Atosa the same as E1 in an older Atosa manual?
Can a dirty condenser cause E1 on an Atosa?
Will my Atosa run with E1 on the display?

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.
