Cleaning Light Blinking 7 Times

Regarding my last message about the Control Board Reset, I forgot to mention the cleaning light is blinking seven times and eveidently this is intended to mean something, although I can’t determine what. Does this mean the control board needs to be reset, or could it mean sopmething else. I’m trying to avoid a repair bill if it’s something I could attempt. Also, I’d like to find how to initiate the diagnostic mode if the machine has one. Thanks.

Here is the tech sheet that explains the 7 blink symptom
