Suddenly Lost of Vapors

[toolate]

I have Sigelei ZMAX+Boge F16 Carto and tank. Everything worked perfectly for a day. But suddenly, little vapors. Battery is OK and Voltage is the same. The tank still have 1/3 of juice. What could possibly be the problem? Should I change the carto? Thanks!

You may have a vapor lock. Try taking a couple of unpowered pulls and see if bubble come out of the carto hole. This might solve the problem temporarily. I had this happen with the Killer 705. It worked fine for weeks and then it just stopped wicking and I had to do the unpowered pulls to get the bubbles or pry up the top cap a little to get bubbles. No bubbles... no wicking....no vapor.
