You've cleared the airway, checked the fill level, and taken slower puffs—but the sound hasn't gone away. At this point, look for leaks.

Remove the pod and wipe the bottom with a dry tissue. If you see liquid on the contacts or in the battery compartment, that's a red flag. A leaky pod can damage the device, and you should stop using it.

What to Check Next

• Pod seating: Make sure the pod is snapped in firmly. A loose pod can cause air to mix with liquid, creating gurgles.
• Airflow ring: If your device has a adjustable airflow, open it fully. A closed airflow can cause a vacuum that pulls liquid into the mouthpiece.
• E-liquid viscosity: Thicker liquids (higher VG) are less likely to leak, but they also might wick slower. Thinner liquids can flood the coil more easily. If you're using a thin liquid, let the pod rest longer.
