SOURCE: The scotsmand machine make ice, but quantity of

Scotsman unit is the CME1856 water cooled
Average batch weight= 20lbs
cycle time 15-17 min
Production 1825-1695/24hrs.
Need more informaton
sensors not the issue unless there on all the time or not blinking as ice passes the infra red signal.
Remember this was a very hot summer and ice demand was high is it possible you have experianced increase volume?

SOURCE: it says harvest time maxed

Hi and welcome to FixYa, I am Kelly.

Download this manual and read page 19 carefully.

http://www.scotsman-ice.com/docs/uploaded/sct/manual/275m.pdf

I think you have a thermistor problem. But... there are several things that will cause the 8 minute max harvest time error. See the diagnostic lights chart on page 19.

Diagnostic Lights:

There are two RED diagnostic lights, one to indicate a water problem, and the other to indicate a refrigeration problem.

Both On all the time / Check for thermistor set unplugged or failed


Additionally see the troubleshooting chart on page 27 "Unit OFF for a harvest problem"


Also make sure to read page 15. The thermistor inputs are on connector #5 left side of the controller


Resets:

Note: The machine may be reset and restarted by

pushing and releasing the Off push button switch,

and then pushing and releasing the freeze push
button switch.

Lastly after a RESET read the initial start up procedures on page 12 right side with regards to the harvest cycle steps 1 - 8.

Thanks for choosing FixYa,
Kelly

Scotsman C0322SA error b after a cleaning which is bin full and there is nothing in it and can reset and tried unplugging for a half hour nothing


This machine has a set of bin eyes that get dirty and it brakes the beam causing the machine to think the bin is full. pull front cover off, pull ice deflector off, where the sump tray is which is where the water returns back there is a plastic grate in there pull it out now reach is where the ice falls into the bin there is two bin eyes one on right side one on left side they will have a gray wire running from them both to the control board you can reach in and pull them straight out to the side the mounts are either gray or black there will be a little red light on them clean these and re install them also there will be a tray that rest above them make sure you push it back up before putting them back in. this will clear the bin full code and start machine up.

The ice sensors are not sensing the ice fall.Wave your hand in front of them the bin full light should blink.If it doesnt clean eyes and conectors.If it still doesnt blink change them they are bad.

Cme256 scotsman ice machine


Clean the bin eyes found in the back of the ice machine where the shoot narrows. Look on the left and right sides of the unit, you will see plastic vanes that are pushed into rubber grommets. Just pull the eyes out and clean with ice machine cleaner.
