I also agree, from what I can remember from the manual, is for an e2 code or e1 code u can pretty much fix it on ur own, w/ changing out the Atty/carto or ur trying to push too many amps with a LR Atty/carto.
But an e7 or e8 code, that is something a bit more serious and its a failure of 1 of the components or something along those lines. But I also could be totally off base, that's just what is in my mind for some reason.
U can go to the Provape site and look at the manual and it will tell u what each code means. No matter what, I would contact Provape and they have some of the best customer service around. They will be more than happy to get u back up and running, if its telling u some tips to get it firing or if u just need to send it back to them. I think all they charge is shipping to them and they will get it back to u in under a week I am pretty sure I've heard (at the most).
