What E11
actually means.
After the compressor starts, an Indigo board expects the discharge line to warm and the evaporator to cool by at least ten degrees before the freeze is two minutes old. If neither moves enough, it logs E11. A compressor that is not really pumping, a contactor that did not pull in, a sealed system short of charge, or a valve stuck open are the kinds of problems behind it.

What to do when E11 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.

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.

With a Manitowoc ice machine, the technician notes what the controls report and checks the bin control before opening the cycle for testing.

Before you book,
in this order.
Each step comes from Manitowoc's own guidance for E11 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Check that the head is on its correct circuit and that the breaker has not tripped.
Restart the head once with the On/Off button and listen for the compressor starting.
If E11 repeats, leave the head off and book a visit; the next checks are on the sealed system and its electrical parts.

What not to do
E11 is not a sensor reading out of limits; those are E21 to E24. A water problem that keeps the plate from freezing is logged as E20 instead.

Questions
about E11.
Can I clear E11 myself?
My Manitowoc logged E11 and the water runs but nothing freezes. What now?
Could E11 on a Manitowoc be a refrigerant leak?
Does E11 happen on every Manitowoc model?

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.
