A vape that worked fine yesterday and feels flat today is annoying, but it’s rarely a write-off.
Most of the time the cause is small and you can check it at home in a few minutes. A weak hit, a burnt taste, no vapour and a leak all point to different things, so this guide goes through them one at a time, cheapest fix first. New gear only comes into it once the free checks have failed.
How to fix a vape that’s not hitting right: check the basics first
When a vape suddenly stops hitting, there’s usually a trigger. The coil has run dry, the battery has dropped, or the airflow has gummed up. All three take minutes to check, and you don’t need to touch the coil to do it.
Charge the battery and check the connections
A half-flat battery is the most common culprit, because many devices still fire when they’re low but can’t push enough power to the coil. Charge it fully, ideally with the cable it came with, since a worn cable or a loose port can leave you thinking it’s charged when it isn’t.
Next, check the connections. Unscrew the tank or take the pod out, wipe the contact pin and the thread with a dry cloth or tissue, then reseat everything gently. Dirt or a slightly loose connection can make a device flicker, cut out or hit weakly, even when the battery and coil are both fine.
Clear the airflow and the mouthpiece
Take the tank or pod off the battery, open the airflow fully and draw on the mouthpiece. The draw should feel smooth and quiet. If it’s tight, whistly or gurgly, something is blocking the path.
Wipe the mouthpiece and the airflow slots with a tissue or a dry cotton bud. Pocket lint and dried e-liquid build up there more than you’d think, especially if the device lives in a bag or a car.
Weak vape hit: wattage, battery and coil checks
If the device fires but the hit feels thin, three things are worth ruling out, in this order: the power setting, the battery and the coil.
Start with wattage. Most coils have a recommended power range printed on the side, and running well below it gives a cool, thin hit. Mesh and Kanthal coils often suit different power and airflow setups, so swapping one for the other without re-checking the wattage can leave a fresh coil feeling weak or harsh.
The battery is next. A battery that sags under load will fire happily for a few puffs and then fade, so the hit gets weaker the longer you vape. If a full charge fixes it for a short while only, the battery is getting tired.
Then there’s the coil itself. Flavour that fades over a stretch of use, along with a dull, flat hit, usually means the cotton is clogged with residue. Your coil has simply had its time.
When your vape isn’t producing vapour at all
A device that fires but gives you nothing usually has one of three problems. The coil is burnt out, the tank is dry, or something is blocking the path.
Check the tank level first. Then look at whether liquid is actually reaching the coil, because thick e-liquid and a low tank can leave the cotton dry even when there’s still some liquid in there. Finally, repeat the airflow draw test from earlier. If the tank is full, the path is clear and there’s still nothing, a burnt-out coil is the likely answer.
None of this will fix a cracked tank or a failed board. These checks only cover the everyday faults.
Why your vape tastes burnt, and what to do about it
A burnt taste almost always means the coil is running dry or running too hot. That’s good news, because the cheap fixes come before any buying: let a new coil soak, top up the tank, and lower the power.
Dry coils and how to prime them
A coil that tastes burnt on its first few puffs is often a new coil that hasn’t had time to soak. A proper refill and soak frequently fixes it without a replacement.
Here’s how to prime it properly. Put a few drops of e-liquid straight onto the cotton through the openings in the coil, fill the tank, and then leave it to sit for a few minutes. Take your first puffs gently at a low power rather than going straight to full whack.
If you chain vape, the coil can dry out faster than the cotton refills, even in a full tank. Pause between puffs and the taste often comes back.
Overheating, old e-liquid and charred cotton
Too much power for the coil is the next suspect. Drop the wattage a notch or two and see if the harshness goes. Thicker, sweeter liquids are tougher on cotton too, so they tend to scorch it sooner at high power.
Old e-liquid can also taste off. If it has darkened, turned syrupy or just smells different from when you bought it, try a fresh bottle before you blame the hardware.
Charred cotton is the one thing you can’t fix. Once it’s scorched, the burnt flavour stays in the coil however much you soak it or turn the power down, so a fresh coil is the answer.
Why is my vape leaking, and how do you stop it?
Leaks nearly always come down to overfilling, a worn seal, a loose pod, or the way the device is stored. Each one is a quick check, and you can usually stop a leak without buying anything.
Seals, overfilling and how you store it
Start with how you fill. Top up gently and stop below the fill line, because a tank packed to the brim has no air gap and will push liquid out through the airflow. Take your time with it.
Then check the seal. If the rubber ring around the tank or pod looks cracked, flattened or has slipped out of its groove, it won’t hold. A seal that has sat at an angle will leak too, so reseat it flat.
With pods, make sure the pod is pushed fully home until it seats properly. A pod that’s only almost in is a classic cause of damp patches on the battery.
Storage matters more than most people expect. Keep the device upright, not on its side, and don’t leave it in a hot car, where liquid expands and gets pushed out.
A freshly soaked coil can also flood, which is the gurgling, spitting sound you sometimes get after a refill. Leave the device to settle for a minute or two before you vape, and take the first puff gently.
When to replace a coil, battery or tank
Replace a part once the basics and a fresh prime have failed. A like-for-like part is usually cheaper than a new device, so it’s worth working out which one has actually finished.
Coils: when a fresh one is the fix
It’s time for a new coil when the burnt taste won’t clear after a proper prime, a refill and a lower wattage. The same goes for flavour that has faded for good. If you’re not sure which type to pick, mesh or Kanthal coils, compared explains how each one behaves at different power levels.
If you go through coils quickly and you’re curious about building your own, rebuildable atomisers versus pre-built coils will help you weigh up the trade-off. Rebuildables take more patience and a bit of practice, so they’re not for everyone.
Batteries and tanks: when they’ve had their day
A battery has finished when it won’t hold a charge, or when a full charge only lasts a short while. Check whether yours is removable before you do anything. If it swells, gets hot while charging or looks damaged, stop using it and don’t try to fix it yourself.
Tanks wear out more slowly, but cracks and perished seals are clear signs. A cracked tank leaks and lets air in, and you can’t repair that. If you’re starting again, a beginner-friendly MTL tank is a straightforward place to begin.
When a disposable or sealed device is the problem
Sealed disposables can’t be opened or re-coiled, so when the draw and battery checks fail, the unit has usually reached the end of its life rather than needing a clever fix.
Try the quick ones first. Wipe the mouthpiece, check the airflow isn’t blocked, and let the device rest for a few minutes in case the liquid hasn’t reached the coil. If it still won’t hit, replace the unit.
If you find yourself replacing disposables regularly, it’s worth comparing refillable pods against disposables on cost before you buy another.
If it’s still not right, ask a Larnaca shop before you buy new
If you’ve worked through the checks and the vape still isn’t right, a quick chat can save you money. Tell us what it’s doing, whether that’s a burnt taste, a weak hit or a leak, and we can usually narrow the cause down in a minute or two. You can also compare buying in store or online in Larnaca if you’re deciding where to spend.
Bring the device along, tank and all, so we can see how it behaves. Then we’ll help you decide whether to fix it, replace a part, or move on to something new.
If you’ve decided it’s time to upgrade, you can trade in your old device and see what happens to it. Otherwise, pop into the Vape Culture shop in Larnaca, and we’ll take a look.
Frequently asked questions
Why is my vape suddenly not hitting?
A sudden change usually has a simple trigger: a battery that has dropped, a coil that has run dry, or airflow that has clogged. Charge the device fully, wipe the connections, top up the tank and do a draw test with the airflow open. If none of that helps, the coil is the next suspect.
Can you fix a vape that doesn’t hit?
Often, yes. A proper charge, cleaner connections, a clear airflow path and a fresh prime fix most cases without buying anything. If those fail, a replacement coil is usually cheaper than a whole new device.
How do I fix a vape that tastes burnt?
First, let a new coil soak properly, top up the tank and lower the wattage. Pause between puffs, too, so the cotton can refill. If the burnt taste stays after that, the cotton has probably charred and the coil needs replacing.
Can a disposable vape that stopped working be repaired?
Not in the usual way, because a sealed disposable can’t be opened or re-coiled. Wipe the mouthpiece, check the airflow and let it rest for a few minutes. If it still won’t hit, replace the unit.
