Most Common Vape Problems and Solutions
Almost every vaping problem you'll ever run into falls into one of a handful of categories: a worn or flooded coil, a battery issue, an airflow blockage, or a leak caused by temperature or pressure changes. None of it is usually a sign your device is faulty, and most of it takes two minutes to fix once you know what you're looking at. What tends to happen instead is that people assume the worst, replace a perfectly good kit, and run into exactly the same issue a week later because the underlying cause was never actually addressed.
This guide runs through the problems we hear about most often at Ecosmok, broken down into likely causes and the actual fix for each one, whether you're on a simple starter kit or a higher-wattage advance kit. We've deliberately kept the causes and fixes side by side for each problem, so you can scan straight to whichever issue you're dealing with, try the fix, and get back to vaping without wading through pages of unrelated troubleshooting first.
1Burnt or Bad-Tasting Hits
That harsh, scorched taste almost always means the cotton inside your coil has dried out and started to burn instead of vaporising e-liquid. It's the single most common complaint in vaping, and it's rarely a device fault. Because the cotton wick can only hold so much liquid at once, anything that outpaces its ability to re-saturate between puffs, whether that's a worn coil nearing the end of its life or simply chaining draws too quickly, exposes dry patches of cotton to the heating element and produces that unmistakable burnt flavour almost instantly.
Likely Causes
- Coil is old and needs replacing
- Chain vaping without letting the wick re-saturate
- Running a new coil dry before priming it
- Wattage set too high for the coil's rating
The Fix
- Replace the coil or pod from our pods & coils range
- Prime new coils by wetting the cotton before first use
- Leave a few seconds between longer puffs
- Check your wattage sits within the coil's printed range
2Leaking Device
A small amount of condensation around the airflow is normal, but visible leaking from the pod or tank usually points to a seal, fill level, or pressure problem rather than a damaged device. E-liquid is drawn through the wick by the coil rather than sitting under active pressure, so when it does escape, something has usually disrupted that balance, whether that's air being forced in through an overfilled pod, a seal that's lost its shape after months of use, or a rapid change in cabin pressure if you've recently flown with your device still full.
Likely Causes
- Pod overfilled past the max fill line
- Coil or pod not seated correctly
- Cracked seal or O-ring
- Sudden altitude or temperature change
The Fix
- Fill only to the marked line, never above it
- Remove and reseat the pod firmly until it clicks
- Check seals for visible cracks and replace if needed
- Store your device upright when not in use
3Weak Vapour or No Vapour at All
If your device fires but produces little to no visible vapour, the coil usually isn't getting enough e-liquid or power to work properly. Vapour production depends on the coil reaching a high enough temperature to vaporise the liquid it's absorbed, so anything that interrupts either side of that equation, not enough juice reaching the wick, not enough power reaching the coil, or airflow that's too restricted for the vapour to escape, will show up as a noticeably weaker cloud than you're used to.
Likely Causes
- Low e-liquid level or empty pod
- Blocked airflow vents
- Wattage set too low
- Battery running low
The Fix
- Top up e-liquid or swap in a fresh pod
- Clear any lint or dust from the airflow slots
- Nudge wattage up gradually within the coil's range
- Charge the device fully before troubleshooting further
The Fastest Fix Is Usually a Fresh Coil
Burnt taste, weak vapour, and a lot of leaking issues all trace back to a worn coil. Before assuming your device is broken, this is the first thing worth ruling out. Genuine replacement pods are cheap, take seconds to swap in, and solve the majority of the problems covered in this guide outright. It's easy to assume a fault this consistent must mean the whole device needs replacing, but in the overwhelming majority of cases the fix is sitting in a pack of spare pods you haven't opened yet. Here are three popular options across different pod kit ecosystems, so there's a good chance one fits what you're already running, and each one below has been chosen specifically because it addresses one of the problems covered earlier in this guide, whether that's flavour longevity, leak resistance, or flexibility across resistances.

Shop NowNot sure which pod fits your device? The name printed on your current pod or coil is the fastest way to check, since manufacturers stamp the resistance and model directly onto the plastic in most cases. If you can't find any markings, a quick photo of your device alongside the current pod is usually enough for our support team to identify the right match, or you can browse the full pods & coils range by brand and cross-check against your kit's original packaging.
4Gurgling or Spit-Back
A gurgling sound usually means excess e-liquid has pooled somewhere it shouldn't, most often the airflow channel or the base of the coil, and it can also cause hot e-liquid to spit into your mouth. This happens because liquid that hasn't been fully vaporised has nowhere else to go but back up through the airflow path, and drawing harder than the coil can vaporise pulls even more raw liquid into that same space, which is why gurgling so often gets worse the more you try to compensate for it.
Likely Causes
- Flooded coil from overfilling or tilting the device
- Inhaling too hard or too fast
- Coil nearing the end of its life
- Device stored on its side
The Fix
- Tap the device gently, mouthpiece down, over a tissue
- Take slower, gentler draws
- Replace the coil if the issue keeps recurring
- Store the device upright between uses
5Battery Won't Charge or Drains Too Fast
Charging issues are usually down to the cable, port, or charging habits rather than a failing battery, especially on a device that's only a few months old. Lithium batteries in vape kits are built to handle hundreds of charge cycles before any real capacity loss sets in, so a sudden change in charging behaviour is far more likely to trace back to something external, a worn cable, a dusty port, or wattage settings that are quietly draining the battery faster than you'd expect, than to the battery itself giving out.
Likely Causes
- Damaged or low-quality USB-C cable
- Debris in the charging port
- Wattage set too high, draining the battery faster
- Natural capacity loss in an older battery
The Fix
- Try a different USB-C cable and power source
- Gently clean the port with a dry, soft brush
- Lower your wattage if you're running near the coil's max
- Consider a fresh starter kit if the battery is genuinely old
6Device Not Firing
If nothing happens when you press the button or draw on the device, it's almost always a connection, sensor, or safety-lock issue rather than a dead device. Most modern kits build in multiple layers of protection to prevent accidental firing in a pocket or bag, and auto-draw devices in particular rely on a pressure sensor detecting your inhale accurately, so a device that seems completely unresponsive is more often being deliberately cautious than genuinely broken.
Likely Causes
- Device is locked (usually 5 rapid clicks to toggle)
- Pod or coil not making contact
- Auto-draw sensor not detecting your inhale
- Battery fully depleted
The Fix
- Click the fire button 5 times quickly to unlock
- Remove and reseat the pod, checking the gold contacts are clean
- Draw a little harder and more steadily on auto-draw devices
- Charge fully before testing again
7Weak Throat Hit
If the vapour is there but the satisfaction isn't, this is almost always about nicotine strength or VG/PG ratio rather than a device problem. Throat hit comes primarily from the nicotine and PG content of the e-liquid rather than from the hardware itself, so a device that's producing plenty of visible vapour but still leaving you unsatisfied is usually a sign the e-liquid side of the equation needs adjusting rather than anything mechanical.
Likely Causes
- Nicotine strength too low for your needs
- High-VG juice used in a low-wattage MTL coil
- Coil resistance mismatched to your device
8Flashing Light Error Codes
Most devices flash their LED a set number of times to signal a specific fault. The exact pattern varies by brand, but a few causes come up again and again. Manufacturers build these warning systems in deliberately, since a chipset that detects a short circuit or dangerously low resistance and simply refuses to fire is protecting both you and the battery, so a flashing light is almost always the device doing exactly what it's supposed to rather than a sign of a serious fault.
Likely Causes
- Short circuit, often from a damaged coil or moisture
- Coil resistance too low for the device
- Battery critically low
- Poor contact between pod and battery
The Fix
- Remove the pod, dry any moisture, and check for damage
- Confirm the coil resistance is within the device's supported range
- Charge fully before retrying
- Clean the contact pins gently with a dry cloth
Preventing Problems Before They Start
A little routine maintenance avoids most of the problems above entirely.
Replace Coils Regularly
Most coils last 1 to 3 weeks depending on use. Replacing them before they burn out prevents most flavour and vapour issues.
Fill Carefully, Store Upright
Stop at the max fill line and keep your device upright when not in use to avoid the majority of leaks.
Use a Proper Charging Cable
A quality USB-C cable and standard wall adapter protects battery health far better than a cheap or damaged one.
When a New Coil Isn't Enough: Time for a New Kit
If you've replaced the pod, tried a new cable, and the problem keeps coming back, the battery itself has probably reached the end of its useful life. Batteries lose capacity gradually over months of daily charging cycles, and no amount of troubleshooting fixes that. Here are three reliable kits worth considering if it's genuinely time to retire your current device.

Frequently Asked Questions
How often should I replace my vape coil?
Most coils last between 1 and 3 weeks with regular use, though sweeter e-liquids and heavier vaping can shorten that. A burnt taste or noticeably weaker vapour are the two clearest signs it's time for a fresh one from our pods & coils range.
Why does my new vape taste burnt straight away?
New coils need priming. If you fire the device before the cotton has fully soaked up e-liquid, it burns dry on the first few puffs. Fill the pod, wait a couple of minutes, and take a few slow draws without firing first if your device allows it.
Is it normal for a vape to leak a little?
A small amount of condensation near the airflow is normal. Visible liquid pooling or dripping from the pod is not, and usually means it's been overfilled, not seated properly, or has a damaged seal.
Why is my vape battery draining so fast?
High wattage settings, a damaged charging cable, or a battery that's simply reached the end of its usable life are the most common causes. Try a different cable first, since it's the cheapest thing to rule out.
My device won't stop flashing. What should I do?
Check the pod is seated correctly and the contacts are clean and dry first. If the flashing continues after that, and especially if the device feels hot, stop using it and get in touch with our customer support team.
Can I fix a burnt coil instead of replacing it?
No. Once the cotton inside a coil has burnt, the taste won't fully recover even after resaturating it. Coils are a consumable part, not something to repair, and a fresh one is the only real fix.
How do I know if it's the coil or the battery causing the problem?
Swap in a fresh pod or coil first, it's the cheaper fix to try. If the same issue continues with a brand new coil fitted, the battery, chipset or connection pins are the more likely cause, and it may be time to consider a replacement kit.
Why does my vape taste different after refilling with a new e-liquid?
This is usually residual flavour from the previous e-liquid still in the coil, sometimes called "ghosting." It's most noticeable when switching between very different flavour profiles, like menthol to dessert. A fresh coil clears it immediately.
Can I use any charging cable for my vape?
Most modern kits use standard USB-C, so many cables will physically fit, but cheap or damaged cables can charge slowly, inconsistently, or in rare cases damage the battery. It's worth using a proper USB-C cable rather than whatever is closest to hand.
Is it bad to leave my vape charging overnight?
Most modern devices have built-in overcharge protection, so occasional overnight charging is unlikely to cause immediate harm. That said, regularly leaving any lithium battery at 100% for extended periods can shorten its lifespan slightly over time, so unplugging once it's full is still good practice.
How long should a vape kit's battery actually last before needing replacement?
Most vape batteries hold up well for 6 to 12 months of regular daily use before capacity noticeably drops. If you're charging far more often than you used to despite normal use, that's a sign the battery is wearing out rather than a coil or e-liquid issue.
