That's what I've heard too. (haven't experienced this as of yet, but sure enough will no doubt eventually).
Pulling the top wire too taunt while tightening it to the post also will do this. It can cut into your wick just enough to cause a short, or it can bend the wick towards the post and cause a short.
Try twisting your wick a bit. If you can still move your wick with the twist pull, then it's not too tight. Twist moving the wick will also set the wire onto a hopefully non shorted oxidized area. (if oxidize is the problem due to too tight of coil and the coil cut
through the wick's oxidiization).
Hope you get those errors fixed!
I so want to pick up a provari! They've scared me from the get go, ever since they first came out. Me and numbers do not get along... and me an menu's are even worse! You should see me with the stupid car radio/cd player. OMG! Just find a song!!
But I aim to get the Mini Pro soon, before we're stuck with hospital payments for the rest of our lives. First is the Precise + though. I've done made up mind AGAIN lol. (I like to confuse myself with various perpetually changing goals).
