what does 2 blinks mean for refrigerant on a scotsman cme256ae-1a

[ectofix]

Two blinks means that there’s an issue with the unit’s ability to sense of the presence of water.

 

Have you properly cleaned the machine?  I advise that you follow the instructions for doing for a proper cleaning of the machine, which should be done a minimum of twice a year.  The instructions for that are on page 12 of your owner’s manual.  Here’s a copy:

Installation and User’s Manual for Modular Cuber Models: CME256, CME506, CME656 and CME806

 

If that doesn’t solve the problem, then you should call a service company to fix it.

Clean the eyes for the bin.  It hasn’t sensed ice harvest..

This may help
