Hi folks, Jax here. Not much of a blogger but in need of your wealth of knowledge. Just switched 1.2 head in new subtank and now my dna30 wont fire. It says check atomizer, although it was working fine till the head swap. My mini nautilus works in dna and subtank fires in several other mech mods. I tried 3 different new and the old head and still no love in dna30 so it has to be the tank. I unscrewed head and it was a bit wet in the base, not a great seal I think, but I dried it to no avail. The pin is not stuck, the negative threads both tank and dna30 are clean and dry but it just aint working. Any thoughts? Also, new battery in mod which again is working with my mini. Much thanks!!!!
