After doing a little research, as I do not have one of these, I think I can explain. If you go to info page on Smok site you will see that the tank does not come off like a traditional tank. The bottom of the tank is the top of the battery. You have to empty all the juice out, take the glass off, then unscrew the coil. At that time you can then access the center pin to gently lift it as described above, or clean out any juice that has seeped past the o-rings, or clean out what ever is shorting the coil to the battery. A search of the web for "Smok 22 troubleshooting" revealed a bunch of issues with these either shorted or open, with suggestions on how to fix each issue. Way too much for me to try and list here. Hope this helps.
Yes. Take the coil off and clean everything. Then pull the small metal contact under the coil down about less than the head of a tooth pick. This will allow the coil to make better contact when you screw the coil back in.
