Well, to close this thread out, the technician came out monday. The answer was to go to the "Maintenance" menu and clear the maintenance log. The guy was nice enough. Too bad he had to spend about 2/3rds of the time on the phone with somebody else to figure it out. He said this is a new "panel" and they don't have the manual on it, yet. This is the relatively new "Nexus" line of generators, and my perception is that Generac has not done a great job of educating their dealer network on the nuances of it.
Any factory trained tech would have known this, Obviously the tech that came to you was not a factory trained tech and should not have be sent out to troubleshoot any problem, Generac does not train Sales dealers. It trains authorized service dealers.
