I've suffered with this issue and a leaking pump, since delivery 3-28-11.
I did the zero reset on two different occasions and it helped for a short time then the unit slipped back into "flight" mode and I finally gave up.
Resorted to using manual mode and gave up on auto mode. As for the leaking pump, the dealer tightened it up twice at the instruction of the Lippert without success, then they replaced the pump but it still leaks.
I have sent a private message to RV Guy for assistance.
