I wanted to add to this in case someone has the same problem. Just bought a High Speed and the first issue was the "Adjustment Failure". It would go away for some reason and then come back again.
I read this post and fixed it. However, in my case there was door button. The issue was any time you unplugged the table or changed the batteries, the next time you turn it on it would give the adjustment failure. I just started the machine holding the door button in with my finger. First it displayed "Factory Reset" and the next start it was fine.
