Yea, I saw it posted here on the forum one time:
E2 means the box tried to move the dish, and didn't get any pulses back from the reed switch.
So, broken reed switch wire, broken motor wire, or . . .
Congrats on a quick fix! - :up
I recall with great fondness when you got that dish and took it home.
Isn't this the one which was already disassembled on some fellows roof?
Your photos were so clear, we easily identified all the bolts 'n nuts from your pictures! -

And I think we called out all the other dishes on that roof, with recommendations on which to snag while you were there.
