If your S17 or S22 tank is refusing to fire, the issue could be down to several things.
Is your device locked?
First off, you should make sure that your battery or device isn't locked (if in doubt, rapidly click the fire button 5 times). As long as the battery lights up, or the device doesn't display a 'locked' message on the screen, you should move onto the following.
Check the coil
The coil you have fitted inside your S17 or S22 tank should be screwed in all the way, until it's finger tight. If the coil is loose, even slightly, it may cause a connection issue and refuse to fire. If the coil is firmly screwed into place and still refuses to fire, you should next try swapping this out for a replacement to help establish if the fault is down to the coil or the tank.
You should at this point also make sure that all of the connections inside and outside of the tank, and in threads on top of your battery or device are clean and free of any debris or e-liquid residue.
If possible, check the tank with another battery to confirm that the problem is with the tank or coil, and not with the battery you're using.
Problems with the airflow
If the airflow section of your tank is out of alignment, it can throw up some connection issues causing the coil to fail to read on your battery or device. Often this related to the device being dropped or knocked, but it's normally a straightforward process to put right.
The tank should appear straight and in alignment when you look at it head on. If you notice a slant, or sizeable gaps between sections of the airflow as pictured below, it's very likely that this is what's causing the issue.
It’s an easy fix though:
- Take the airflow off of your tank
- Take the coil out of the airflow
- Place the airflow on a solid surface
- Push down on the airflow with plenty of force (easier to do by placing a heavy book on top). It might ‘pop’ as it slots back into position
That should be enough to realign the airflow, allowing for a solid connection between the tank/coil and battery, and resolve the issue.
