What Error 5
actually means.

An Elevation CIM harvest ends when the falling ice opens the curtain switches. If that has not happened after 7.5 minutes, the board shows Error 5. Scale on the evaporator, a curtain that does not swing, a harvest assist that does not push, or a hot gas valve that does not open are the common reasons.

What to do when Error 5 shows on the ice machine

Before you book,
in this order.

Each step comes from Ice-O-Matic's own guidance for Error 5 on its ice machines. Follow it to the end: the last card says whether this is a visit.

01

Open the head and check that the curtains swing freely and nothing is jammed against them.

02

Plan a cleaning with a nickel-safe cleaner if the last one was more than six months ago.

03

Clear the code with POWER and CLEAN held for three seconds; if it returns, book a visit.

What not to do

Error 5 is not the one-hour freeze of Error 1. If both limits were hit, the board shows Error 6 instead.

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Elevation Series CIM modular cubers. Codes show as red and yellow flash patterns on the POWER and CLEAN buttons of the push pad and the board. Boards before serial 2106 grouped some limits differently. Boards before serial 2106 used a 5-minute harvest limit.

Questions
about Error 5.

Can I clear Error 5 myself?
Open the head and check that the curtains swing freely and nothing is jammed against them. If it comes back, it needs a visit.
Why must I use a nickel-safe cleaner on my Ice-O-Matic?
The CIM evaporator is nickel-plated. Ice-O-Matic warns that the wrong cleaner can strip the plating, which then makes the ice cling and harvest slowly.
Can a stuck curtain cause Error 5 on an Ice-O-Matic?
Yes. The harvest ends when the curtain opens, so a curtain that cannot swing looks like ice that never fell.
Does Error 5 mean the same on older Ice-O-Matic boards?
The meaning is the same, but boards before serial 2106 used a 5-minute limit rather than 7.5.

Back to your everyday

Still showing Error 5?

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.
