If that's the worst thing that ever happens to you throughout your
vaping career you are WAY ahead of the game.
First thing is to check it on another device, because the positive post may be slightly off and causing it not to fire. Then check to make sure that the head is seated all the way, you may have inadvertently unscrewed it filling it up. Both of these things have happened to me before.
Last of course is that the element popped. Which is tragic indeed.
