Scotsman code 1: freeze too long on a cuber, no ice sensed on a nugget machine

On a Prodigy cuber, 1 means the freeze passed its maximum time; a blinking 1 means the controller is retrying and a steady 1 means it gave up after three long freezes in a row.

What 1
actually means.

On a Prodigy cuber, 1 means the freeze passed its maximum time; a blinking 1 means the controller is retrying and a steady 1 means it gave up after three long freezes in a row. On a CM3 nugget or flake machine, the photo eyes in the ice chute saw no ice within the allowed time; a blinking 1 is a ten-minute pause and retry, a steady 1 is a shutdown after three misses. Both come down to water, airflow, or a weak cooling system.

What to do when 1 shows on the ice machine

Before you book,
in this order.

Each step comes from Scotsman's own guidance for 1 on its ice machines. Follow it to the end: the last card says whether this is a visit.

01

Check that the water supply is on and the filter cartridge is not overdue.

02

Clean the air filter in front of the condenser and clear anything blocking the intake or exhaust.

03

Restart by pressing Off and then On; if a steady 1 comes back, book a visit.

Still there?

It usually turns into ice machine harvest repair. Book with the code and the model number.

What not to do

A blinking 1 is a retry, not yet a shutdown, so a machine showing it may recover by itself. On a cuber the code does not concern the curtain or harvest; that is 2.

Where 1 usually leads

Ice machine harvest repair.

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Prodigy and Prodigy ELITE cubers (MC and C models) show one character in the code display next to the lights. Prodigy flaked and nugget machines with the CM3 control (N and F models) use the same display with a different code list. Cuber maximum freeze on the ELITE is 45 minutes.

Questions
about 1.

Can I clear 1 myself?
Check that the water supply is on and the filter cartridge is not overdue. If it comes back, it needs a visit.
What does a blinking 1 mean on my Scotsman Prodigy?
The controller has hit the time limit once and is trying again. If later cycles finish in time, it goes back to normal; three misses in a row turn the 1 steady and stop the machine.
Why does my Scotsman nugget machine show 1 when the bin is empty?
On nugget machines the 1 comes from photo eyes in the ice chute that saw no ice. Dirty eyes, low water or a cooling problem can all cause it.
How do I restart a Scotsman after a steady 1?
Scotsman's reset is to press Off and then On. If the 1 returns, the cause is still there and a visit is needed.

Back to your everyday

Still showing 1?

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.
