This one is giving a constant f06e02 code (UI to CCU communication). I've checked the harness between the two for continuity, all good. 12vdc and 5vdc check ok. UI tests ok for all buttons and leds. Clear the code, try to start, door locks, dispenser cycles, then everything stops and the code is set again.
I saw several others in previous posts with same or very similar problem, but no solutions. Does anyone have a fix for this?
