What E9
actually means.
True reads the sump level through a small tube that carries air pressure to a sensing chip on the board. E9 points to that tube being damaged or kinked, or to the chip not seating properly, and the fill, purge and leak checks cannot work without it.

What to do when E9 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.

True ice machine visits begin with the installation: the supply, the drain fall and the clearance the machine needs to cool.

Before you book,
in this order.
Each step comes from True Residential's own guidance for E9 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Turn the head off at the touchscreen.
If you can see the sensing tube from the sump without removing any panel, check it for kinks or a loose end.
Book a visit; the tube and the board contact are checked with the covers off and power isolated.
Still there?
It usually turns into ice machine bin control repair. Book with the code and the model number.
What not to do
E9 is a lost signal, not a real fill or drain problem, although it can stop both. E23, a level calculation alarm, is a different event read by a technician in the log.

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.
