Fired up the CS570 today. Everything worked fine except Auger wasn't turning on, either automatically or with the Prime button. Will see if motor or control panel is the issues. Email into support so we will see

Is it still a 4 plug system?  Can you plug the auger motor connection to one of the other and see if it operates?

This is a good point. I might try that. Without seeing it in front of me, I think I remember it being 2 wire system, but will check.
