What E01
actually means.
Every freeze cycle has a ceiling on a Manitowoc Indigo head. When the ice thickness probe never calls for harvest before that ceiling, the board forces a harvest, counts the miss, and after enough misses in a row it stops the machine and stores E01. Scale on the evaporator, a starved water trough, a hot or dirty condenser and a weak sealed system all stretch the freeze.

What to do when E01 shows on the ice machineKind of codeHarvest and freeze cycle
A freeze ran longer than the board allows, or a harvest started and the ice never fell. Scale on the evaporator holds the sheet to the plate, a thickness probe crusted with minerals never signals, a hot gas valve that does not open leaves the plate cold, a harvest assist that does not push, or a water curtain that swings without tripping its switch all end in this family. A cleaning cycle run by the manual often clears it; a valve or a probe is a technician's job.

The hot gas valve, harvest assist, curtain switch and thickness probe that decide when a sheet of cubes is done and make it drop.
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.

Indigo and Indigo NXT modular heads keep E-numbers in the Event Log (Menu, Service, Event Log). Older Indigo boards stop after six 60-minute freeze cycles; Indigo NXT firmware stops after three 35-minute ones.
Before you book,
in this order.
Each step comes from Manitowoc's own guidance for E01 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Restart the way Manitowoc describes: press On/Off until the screen reads Off, then press it again so it reads Making Ice.
Check that the water supply valve to the head is open and that the room around the head is not unusually hot.
Look at the condenser grille or air filter; if it is matted with dust, clean the filter as the manual shows.
If the head stops again with E01, book a visit so the probe, the water level and the sealed system can be measured.

What not to do
E01 does not mean the ice falls slowly or sticks; that is E02. It also is not a power problem, because the board keeps running cycles until the count is reached.

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.
