What ICE and DRAIN blinking
actually means.
U-Line places an air sensor in front of the condenser so the control can adjust to the room. When the sensor reads open or shorted, ICE and DRAIN blink together.

What to do when ICE and DRAIN blinking 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.
Usually leads toIce machine bin control repair
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.

What not to do
This pattern is about a sensor, not about draining, even though the DRAIN lamp blinks. DRAIN blinking alone is Er16, a slow drain.

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.
