Vape not producing vapour? Ten fixes that work
Only got a minute?
- Charge it first, then look at the coil. A flat or nearly flat battery and a worn coil are the two most likely causes, in that order.
- Clean the contacts and the airholes. Liquid on the 510 thread or pocket fluff over the intake stops a device dead even though nothing is broken.
- Prime a new coil and wait. Wet the wicking ports, fill the tank and leave it five to ten minutes before you press the button, or you will burn it on the first puff.
- Draw slowly for two to three seconds. Short sharp puffs on an auto-draw pod often fail to trip the sensor at all.
- If none of it works, the coil, the pod or the battery has reached the end of its life. A fresh coil is the cheapest thing to rule out before you replace a whole kit.
Why a vape stops producing vapour
A vape has a very short chain of events. The battery sends current to a coil, the coil heats the wick, the wick holds liquid, and air pulled through the device carries the vapour to your mouth. Break any one of those four links and you get nothing, or so little you barely notice it.
Most of the time the fault is not a fault at all. It is a battery that has quietly dropped below its cut-off, a coil that has reached the end of its life, a bit of fluff sitting over an air intake, or a liquid that is too thick for the coil you have fitted. Genuine hardware failure is rarer than people assume.

Work through these ten fixes in order
They are ordered from the quickest and most likely to the slowest and least likely, so do not skip ahead.
- 1
Charge it fully and leave it on charge for a few extra minutes. A lithium cell near its cut-off can still light up and still fire the sensor while delivering nowhere near enough current to heat a mesh coil. If the light blinks three or four times and stops, that is the low-voltage warning, not a fault. Use the USB-C cable supplied with the kit, plugged into a standard low-output USB plug or a computer port, and check the port for lint before you blame the battery.
- 2
Take a slow, long draw. Auto-draw pods need a steady pull of two to three seconds to register. A quick sharp tug moves very little air and often does not trip the sensor at all. On a button-fire device, hold the button for a half second before you start inhaling so the coil is already warm.
- 3
Find the air intakes and make sure nothing is over them. Air has to get in somewhere, usually a slot or two small holes near the base or around the pod seam. Pocket fluff, a case, a thumb or a tight grip will block them. Hold the device loosely, look for the holes and clear them with a dry cotton bud. Check the mouthpiece too, since condensed liquid can set in the drip tip and choke the draw.
- 4
Open the airflow control. If your tank or pod has an adjustable ring, it may have rotated shut in a bag or pocket. Wind it fully open, take a puff, then close it back to where you like it. On a tight mouth-to-lung setting a coil designed for more air will feel completely dead.
- 5
Reseat the pod or retighten the tank. Pull the pod out, wipe the contact pins and the well underneath with kitchen roll, and click it back in firmly. On a threaded tank, unscrew it and screw it back down snugly without forcing it. Liquid sitting on the contacts is a frequent reason a device shows power but will not fire, and thirty seconds with a dry cloth fixes it.
- 6
Check the liquid level and refill properly. If the wick is dry you get no vapour and a harsh taste. Fill to the line, never past it, keep liquid out of the central chimney and give it a few minutes to soak in. Our guide on how to fill a pod kit correctly walks through it. Remember a nicotine-containing pod or tank is capped at 2ml in the UK, so it empties faster than you think.
- 7
Fit a fresh coil and prime it. Coils are consumable. Most last one to three weeks depending on how much you vape and how sweet your liquid is. Drip two or three drops onto each wicking port, fill the tank, screw it together and leave it standing for five to ten minutes. Then start on a lower wattage and work up. Browse replacement coils by kit, or fit a fresh prefilled pod if your device uses those.
- 8
Clear a flooded coil. Gurgling, spitting, a wet mouthpiece and thin weak vapour all point to too much liquid around the heating element. Take the pod out, tip it upside down over kitchen roll and flick it gently, or blow through it from the base into a cloth. Then take slower draws with a short pause between them. If it keeps flooding, see how to stop e-liquid leaks.
- 9
Match the wattage to the coil. Every coil is printed with a resistance and a recommended range. A 0.8Ω mouth-to-lung coil is happy at 12W to 16W; run it at 6W and you get a wisp of vapour, run it at 35W and you cook it. Set it to the middle of the stated range. If your kit has a preheat or a power mode, take it off the lowest setting.
- 10
Swap the liquid, then accept the device is finished. A thick 70/30 VG shortfill in a tight pod coil will not wick and will read as no vapour. Move to a 50/50 10ml or a nic salt and try again. If a new coil, a clean pod, a full charge and a suitable liquid still give you nothing, the battery or the board has failed and it is time for a new kit.
It lights up but nothing comes out
This is a common version of the problem, and the light is a red herring. The LED is driven by the board, not by the coil, so a device can flash away with an open circuit above it. There are three realistic explanations.
Wrong wattage
A coil run well below its printed range gives a wisp and nothing more. Check the range stamped on the coil and set the middle of it.
Burnt coil
The wick has carbonised and the coil no longer holds liquid. You will usually taste it first. Fit a new coil.
Empty pod
Tinted plastic hides how little is left. Hold it to a light. A 2ml pod at the bottom of the window is basically dry.
The Smok Nord coils pictured above are a typical example: kit-specific, sold in multipacks and the first part to swap once the free checks are done. If you are working through more than one symptom at once, our wider guide to eight common vape problems covers leaking, burnt taste and auto-firing alongside this one.
Refillable kit or rechargeable prefilled pod kit?
Single-use disposable vapes have been banned from sale in the UK since 1 June 2025, so the grab-and-go option now is a rechargeable prefilled pod kit: a reusable battery with a replaceable pod on top. They suffer the same faults as a refillable kit, but you fix them differently, because you cannot get inside the pod.
| Symptom | Refillable pod or tank | Rechargeable prefilled pod kit |
|---|---|---|
| No vapour at all | Charge, then change the coil | Charge, then change the pod |
| Weak or thin vapour | Open airflow, raise wattage, check ratio | Open airflow, warm it up, draw slower |
| Burnt taste | New coil, lower the power | New pod, the wick cannot be reprimed |
| Gurgling | Empty the chimney, do not overfill | Tip out, blow through, pause between puffs |
| Lights, no output | Clean the 510 thread or pod pins | Clean the pins, then swap the pod |
| Cheapest thing to replace | A coil | A pod |
Kits such as the Lost Mary BM6000 and the Elf Bar Elfa both work this way, and a spare pod in the drawer is the fastest possible fix. Pod choice is covered in the BM6000 refill pods guide.
The conditions that cause it, not the hardware
Cold. E-liquid thickens as the temperature drops, and thick liquid wicks slowly. A device left in a car overnight or carried in an outside coat pocket in January will give you a fraction of its usual output for the first few puffs. Warm it in a closed hand for a couple of minutes before you use it. VG-heavy liquid is worse affected than 50/50.
Chain vaping. Puff after puff without a break heats the coil faster than the wick can resupply it. Output falls away and you eventually get a dry hit. Ten to fifteen seconds between puffs lets the wick catch up on most kits.
Storage. Lying a kit on its side or upside down lets liquid creep into the airway and flood the coil. Stand it upright. Keep it out of direct sunlight and out of hot cars, both of which degrade the liquid and the cell. The same applies to spare bottles, which is covered in our e-liquid shelf life and storage guide.
Strength expectations. Sometimes the vapour is fine and the hit is not. Dropping from 20mg to 10mg makes the throat sensation much lighter, and people read that as a weak device. If the cloud looks normal but it feels like nothing, read how much nicotine you should vape before you replace any hardware. UK law caps nicotine liquid at 20mg/ml, so that is as strong as it gets.
The wrong inhale for the kit. A direct-to-lung device drawn on like a cigarette feels flat, and a tight mouth-to-lung pod drawn on hard feels blocked. Our guide to MTL versus DTL inhalation styles explains which you are and what kit suits it.
Stopping it happening again
Nearly all of this is preventable with a five-minute habit once a week. Empty the tank, rinse the pod body in warm water and let it dry completely before refilling. Keep the airholes clear and change the coil on a schedule rather than waiting for a burnt taste.
Buy consumables to match the kit you own, since an almost-correct coil will seat badly and wick badly. Popular fits such as the Voopoo PnP five pack come in multipacks, so keeping a spare set on hand costs very little. Charge with the supplied USB-C cable on a low-output plug rather than a fast-charge brick, do not charge unattended overnight, and let a hot device cool before plugging it in. A few more habits worth dropping are in common vaping mistakes beginners make.
If your device is several years old, has been dropped, or has had liquid inside the battery section, replacement is the sensible call. A modern refillable pod kit will be more reliable than anything you can nurse back to life, and our best pod kits for beginners roundup is a good place to start.

Quick answers
My vape lights up but produces no vapour. What now?
Wipe the pod pins and the battery well dry and reseat the pod. If that does nothing, the coil has burnt out or the pod is empty. Both are cheap to replace and take a minute.
Why is a brand new kit weak straight out of the box?
Almost always an unprimed coil or a partly charged battery. Kits ship with a partial charge, so plug it in on the supplied cable first, and follow step five for the coil before the first session.
Does cold weather really reduce vapour?
Yes. Cold thickens the liquid so it wicks more slowly, and a cold cell delivers less current. Warm the device in your hand for a minute or two and output returns to normal.
How often should I change a coil?
One to three weeks for most people. Sweet and dark dessert flavours gunk a coil faster than light fruits or menthols, so heavy users of those should expect the shorter end.
Can I use any e-liquid in any kit?
No. Thin 50/50 liquid suits mouth-to-lung coils in the 0.6Ω to 1.2Ω range, and thicker high-VG liquid suits sub-ohm coils below about 0.6Ω. Using the wrong one is a common cause of weak vapour and burnt wicks.
When is it time to give up and replace the device?
When the steps above, a full charge, a new coil or pod and a suitable liquid, still give you nothing, or when the battery no longer holds charge through a day. At that point the board or cell has failed.
