You unboxed a fresh vape, filled the pod, waited a bit, and took a puff—only to hear that wet, bubbly sound. It's annoying, but it's rarely a sign of a broken device. More often, it's because the coil got more liquid than it can handle right away. That happens when you overfill the pod, prime the coil too aggressively, or don't give the liquid time to settle.

Start with the simplest fix: remove the pod and blow gently through the mouthpiece into a tissue. You'll see some liquid come out. That's the excess that was sitting in the airway. Reinsert the pod and take a couple of dry puffs (don't press the button) to help pull the liquid into the coil properly.
