Scotsman Ice Machine Light: Blinking Yellow De-Scale and Sanitize

What does Scotsman De-Scale and Sanitize light blinking yellow mean?

The De-Scale and Sanitize light is one of four indicator lights on the Scotsman Prodigy Plus D Series cuber. The manual's table of indicator lights lists it blinking yellow as In Cleaning mode, with a cleaning cycle in progress. While the cycle runs, the machine circulates cleaning solution and rinses, and it makes no ice. The table gives only the meaning of the light. It does not list causes, and it does not say how long the cycle takes. It suggests contacting a service agent for patterns that need more help. The yellow blinking is therefore a sign to leave the machine alone. If you did not start the cleaning, ask who did, since the cycle can be started by a person pressing the key. Only if the light blinks far longer than expected is there a case to call for help.
