What E19
actually means.

The Indigo ice thickness probe tells the board when the sheet of ice is thick enough to harvest. If its signal drops outside the expected band, because the probe is unplugged, scaled over or damaged, the board logs E19. With five good cycles of history it keeps the head running in safe mode for up to 72 hours.

What to do when E19 shows on the ice machine

Before you book,
in this order.

Each step comes from Manitowoc's own guidance for E19 on its ice machines. Follow it to the end: the last card says whether this is a visit.

01

Check the display for a safe mode alert; the head may still be making ice on timed cycles.

02

Plan a de-scale and sanitize, since scale on the probe is a common reason it misreads.

03

Book a visit before the 72 hours run out, so the probe can be cleaned, adjusted or replaced.

What not to do

E19 is not a water level problem, which the board logs as E20. It also does not mean the freeze is slow; a probe that reads but calls too late produces E01.

Questions
about E19.

Can I clear E19 myself?
Check the display for a safe mode alert; the head may still be making ice on timed cycles. If it comes back, it needs a visit.
My Manitowoc still makes ice after E19. Is it fixed?
Not yet. Safe mode runs the head on the times it learned from recent cycles, and after 72 hours it goes to standby. Use that window to get the probe looked at.
Can dirty water cause E19 on a Manitowoc?
Scale and slime on the probe change what it senses, and the manual names a dirty probe among the reasons a head will not harvest. Cleaning often helps.
Why are my Manitowoc cubes thin after an E19 entry?
Without the probe, cycle length is estimated, so the cubes can come out thinner or thicker than usual until the probe works again.

Back to your everyday

Still showing E19?

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.
