Why Is My Vape Leaking? 7 Common Causes and Simple Fixes
Share
If you’ve ever taken a drag from your vape and been met with a burnt, metallic or harsh taste, you know how instantly off-putting it can be. It’s one of the most common complaints among UK vapers — and luckily, most of the time, it’s an easy fix. In this guide, we’ll walk through the leading causes of a burnt or unpleasant vape taste, what to do about each, plus a few habits that will help you avoid the problem in future.
1. Your Coil Needs Replacing
The number-one culprit is a worn-out coil. Over time, e-liquid residue builds up on the coil’s cotton wick, turning it dark and gummy. When that happens, the cotton can no longer saturate properly and starts to burn.
How to tell: You get a dry, scorched taste on every puff, often accompanied by reduced vapour.
Fix: Swap in a new coil. Most pod kit coils last anywhere from 5 to 14 days depending on your e-liquid, vaping frequency and power settings. If you’re unsure, order a compatible replacement for your device from our coils and pods range.
2. You Didn’t Prime Your Coil
Brand-new coils can burn out on the first draw if they haven’t been pre-soaked. Priming means a few drops of e-liquid directly onto the exposed cotton before assembly, then a 5–10-minute wait with the tank topped up.
How to tell: A harsh, burnt flavour appears almost immediately after a coil change.
Fix: Prime every new coil — it takes three minutes and can add days to the coil’s lifespan.
3. Dry Hits from Chain Vaping
Puffing too frequently without giving the wick time to re-saturate leads to dry hits — and that characteristic burnt taste.
How to tell: You catch a sharp, scorched hit mid-session, often after back-to-back puffs.
Fix: Slow down between draws. If you chain-vape, consider using a higher-VG liquid or a rebuildable setup that can keep up.
4. Low E-Liquid Level
Most tanks show a minimum fill line for a reason. Running too low means the coil’s wick is only partially submerged, leading to partial dry hits.
How to tell: The burnt taste comes and goes, often at an angle when your tank is almost empty.
Fix: Top up before you hit the minimum line. It’s an easy habit that saves coils and money.
5. Wrong E-Liquid VG/PG Ratio for Your Device
High-VG liquids (70VG/30PG and above) are thicker and harder for small wicks to absorb. In a low-powered pod kit, that can cause dry hits even with a new coil.
How to tell: You’re running a sub-50 W device with 70VG+ liquid and getting frequent burnt tastes.
Fix: Switch to a 50VG/50PG blend or a nic salt designed for MTL devices. Browse our nic salt range for options that perform reliably in pod kits.
6. Over-Sweetened E-Liquid
Super-sweet custards, desserts and candy flavours leave more residue on coils than menthol, tobacco or icy blends. That residue carbonises faster, shortening coil life.
How to tell: Your coil turns dark (almost black) within 2–3 days, and the flavour fades quickly.
Fix: Alternate with a lighter, less sweet liquid, or accept shorter coil changes as the trade-off for dessert flavours.
7. Airflow Blocked or Restricted
Blocked or overly restricted airflow causes heat to build up around the coil, burning the wick even when the liquid level is adequate.
How to tell: Hot, harsh vapour with a burnt aftertaste, especially if you’re taking long, slow draws.
Fix: Adjust your airflow to a slightly looser setting, and make sure the air holes or vents are clear of lint or debris.
Quick Troubleshooting Checklist
| Issue | Likely Fix |
|---|---|
| Consistent burnt taste | Replace coil |
| Burnt taste after coil change | Prime the coil |
| Occasional burnt hit | Slow your puff rate |
| Taste worsens at an angle | Top up e-liquid |
| Coil turns very dark | Try a less sweet liquid |
| Hot, harsh vapour | Check airflow |
When a Burnt Taste Means Something More Serious
If you’ve tried the fixes above and still get a persistent metallic or burnt taste, it might be worth popping into your local Norwich Vape store. A quick device inspection often reveals hardware faults — a failing pod connection or an old tank — that are cheap and easy to sort.
Bottom Line
A burnt or metallic vape taste is rarely a big mystery. By checking your coil age, priming habits, liquid levels and wattage settings, most UK vapers can fix the issue in under five minutes. Keep spare coils on hand, match your e-liquid to your device, and you’ll enjoy clean, consistent flavour all week long.
