Why Is My Vape Spitting? Fixes for Spitting and Gurgling
Hot drops on your tongue, crackling and gurgling: how to clear a spitting vape in a minute, then fix the cause so it stays fixed.
A crackle, a gurgle, and then a hot drop of liquid on your tongue. Spitting, sometimes called spitback, is one of the most common vape complaints, and it’s almost always fixable in a minute or two. It’s nearly always caused by liquid sitting where it shouldn’t: in the coil, in the airway, or in the chimney. This guide shows you how to clear it right now, then works through the causes in the order most likely to fix it for good.
The short version
- Quick fix: remove the pod or tank, wrap a tissue around the base, and blow firmly through the mouthpiece two or three times to push out pooled liquid.
- Most common causes: a flooded coil, overfilling, power too low for the coil, hard or fast draws, and thin liquid in a large coil.
- If a fresh coil still spits after these fixes, the coil may be faulty or worn out.
Fix it right now
- Take the pod out (or unscrew the tank from the mod).
- Hold a tissue or paper towel over the base and airflow holes.
- Blow firmly through the mouthpiece two or three times. Liquid in the airway gets pushed into the tissue.
- Wipe the contacts on the pod and inside the device so they’re dry.
- Put it back and take a slow, gentle puff.
On a tank, you can also flick it downwards a couple of times, mouthpiece up and airflow covered with a tissue, to sling out excess liquid. That clears today’s spitting. The steps below stop it coming back.
Why vapes spit: causes and fixes, in order
1. The coil is flooded
When the cotton holds more liquid than the coil can vaporise, the excess boils and pops instead of turning into vapour. That causes the crackle and the spit. Flooding usually follows too many primer puffs, a hard draw that pulls extra liquid in, or a device left on its side.
Fix: clear it as above, then take a few short puffs at slightly higher power (within the coil’s range) to burn off the surplus. Prime new coils with two or three gentle primer puffs, not ten. See how to prime a coil.
2. The pod or tank is overfilled
Filling to the very top leaves no air space and pushes liquid into the coil and down the airway, especially as the device warms up in your pocket.
Fix: fill to just below the maximum line and leave a small air gap at the top. Close fill ports firmly and wipe away any spills.
3. The power is too low
Below the coil’s range, the coil can’t vaporise liquid as fast as the cotton supplies it, so you get a wet, gurgly draw and the occasional spit.
Fix: raise the wattage a couple of watts at a time, staying inside the printed range. Our wattage guide shows typical ranges by resistance.
4. You’re drawing too hard or too fast
A strong, short pull creates a lot of suction and drags liquid through the coil faster than it can vaporise. It’s common when people move from disposables or cigarettes to a refillable device.
Fix: take slower, steadier draws. On adjustable devices, opening the airflow a little reduces suction too.
5. The liquid is too thin for the coil
High-PG liquid is thin and soaks into cotton very quickly. In a big, low-resistance coil that can mean more liquid than the coil can handle.
Fix: use a liquid with more VG in larger coils, or a higher-resistance coil for thinner liquids. See PG vs VG and MTL vs DTL for how liquid, coil and draw style fit together.
6. Condensation has built up
Every puff leaves a little condensed vapour in the chimney and mouthpiece. Over days, it pools and starts to spit or gurgle.
Fix: wipe the mouthpiece and blow the pod through into a tissue every day or two. Clean the pod and contacts properly once a week. See how to clean a vape.
7. The coil is worn out or faulty
Old coils with gunked-up cotton don’t absorb and release liquid evenly, and occasionally a new coil simply has loose or uneven cotton.
Fix: if spitting continues after everything above, try a fresh coil or pod. Signs a coil is done include a burnt or muted taste and less vapour. See how long do vape coils last?
Spitting vs leaking vs gurgling
| Symptom | What’s happening | Start with |
|---|---|---|
| Hot drops on your tongue, crackling | Spitting: liquid boiling at the coil | Clear it, check power and draw |
| Bubbling or gurgling sound | Liquid sitting in the airway | Blow it out, check fill level |
| Liquid on the device or in your pocket | Leaking: liquid escaping the pod or tank | Why is my vape leaking? |
The three often travel together, because too much liquid in the wrong place causes all of them.
Device-specific tips
- Small MTL pods (e.g. XROS): spitting usually means overfilling or a hard draw. Fill down the side, leave an air gap, and take gentle puffs.
- Draw-activated devices: a very hard pull can both flood the coil and trigger the sensor. A slow, steady draw fixes both.
- Sub-ohm tanks: raise the power within range and use higher-VG liquid. Many sub-ohm coils spit when underpowered.
- Rebuildables and boro bridges: spitting often means the wick is too loose or the tails are too thick. Rewick slightly tighter and trim the tails.
FAQ
Is vape spitback dangerous?
It’s mostly unpleasant: a hot drop of liquid on the lips or tongue. If it happens, stop, clear the device and fix the cause. Rinse your mouth if you get liquid in it.
Why does my new vape spit?
New coils are often over-primed, or the pod was overfilled on the first fill. Clear it and take a few gentle puffs.
Why does my vape spit only on the first puff?
Condensation and liquid settle in the airway while the device sits. A quick blow-through before your first puff, or one short “throwaway” puff, usually solves it.
Does a drip tip stop spitting?
Some tanks offer drip tips with anti-spit designs that help stop drops reaching your mouth, but they don’t fix the cause. Start with the fill level, power and draw.
