Why Your Vape Tastes Burnt, Weak or Leaks: Common Vape Problems Explained

If your vape suddenly tastes burnt, produces weak vapour, or starts leaking e-liquid everywhere, you are not alone. These are some of the most common vape problems UK vapers deal with daily, whether using pod kits, refillable vape kits, or advanced sub-ohm devices. The good news is that most vaping issues are easy to fix once you understand what causes them. In this guide, we explain the most common vape problems, why they happen, and how to fix them properly. Whether you are dealing with a burnt vape, weak vaping performance, leaking pods, or poor flavour, this guide will help you get your device working properly again. Why Does My Vape Taste Burnt? A burnt vape taste usually happens when the coil inside your device overheats and burns the cotton wick instead of vaporising e-liquid. Once the cotton becomes scorched, the flavour becomes harsh, dry, and unpleasant. Common Causes of a Burnt Vape 1. Your Coil Was Not Primed Properly One of the biggest causes of a burnt vape is using a brand-new coil too quickly. New coils contain dry cotton that needs time to absorb e-liquid fully before vaping. If you fire the device immediately after filling the tank, the cotton can burn instantly. How to Prime a Coil Properly: Add a few drops of e-liquid directly onto the exposed cotton Install the coil into your tank or pod Fill the tank completely Leave the device for 5 to 10 minutes before vaping Start vaping at a lower wattage first 2. Chain Vaping Taking too many puffs in quick succession prevents the wick from soaking up enough e-liquid between draws. This causes dry hits and eventually leads to a burnt vape coil. Signs You Are Chain Vaping: Vape becomes hotter after repeated puffs Flavour suddenly tastes dry Vapour production drops The coil burns out quickly 3. Wattage Is Too High Every coil has a recommended wattage range. Running your device above that range can burn the wick much faster. Coil Type Recommended Usage Higher resistance coils Lower wattage mouth-to-lung vaping Sub-ohm coils Higher wattage direct-to-lung vaping Mesh coils Faster heating and stronger flavour Always check the wattage recommendation printed on the coil itself. 4. Low E-Liquid Levels If the e-liquid level drops below the coil openings, the wick dries out and burns. This is especially common with smaller pod systems. Quick Tip Never let your pod or tank run completely empty before refilling. 5. Sweet or Thick E-Liquids Very sweet e-liquids or high VG vape juices can clog coils faster and reduce coil lifespan. This can create: Burnt flavour Weak vaping Reduced vapour production Faster coil degradation Why Does My Vape Feel Weak? Weak vaping is another common issue that affects flavour, vapour production, and nicotine delivery. If your vape suddenly feels less satisfying, several things could be causing it. Common Causes of Weak Vaping 1. Your Coil Is Old Coils naturally wear out over time. Residue builds up on the heating element, reducing flavour and vapour. Signs Your Coil Needs Replacing: Weak flavour Muted taste Darkened e-liquid Crackling sounds Reduced vapour production Most vape coils last: 5 to 14 days for regular users Longer with lighter usage 2. Low Battery Power As battery levels drop, some vape kits produce less power. This can make vapour feel weak or inconsistent. Fix Fully recharge the battery Check battery health Replace older batteries if needed 3. Incorrect Airflow Settings Airflow has a huge effect on vapour production and flavour. Airflow Setting Result Tight airflow Stronger throat hit and flavour Open airflow Bigger clouds and cooler vapour Incorrect airflow settings can make your vape feel weak even if the coil is working properly. 4. E-Liquid Strength Is Too Low Sometimes the issue is not the device at all. If you recently switched to a lower nicotine strength, your vape may feel weaker than usual. This is especially noticeable for ex-smokers transitioning from stronger nicotine products. 5. Poor Coil and E-Liquid Match Some e-liquids work better with specific coil types. E-Liquid Type Best Device Type 50/50 e-liquids Pod kits High VG shortfills Sub-ohm kits Nicotine salts Low-wattage devices Using the wrong combination can reduce flavour and vapour significantly. Why Is My Vape Leaking? A leaking vape can waste e-liquid and create a messy experience, but it is usually fixable. Most vape leaks happen because of airflow pressure issues, damaged seals, or incorrect filling. Common Reasons Your Vape Leaks 1. Overfilling the Tank Filling your pod or tank beyond the maximum line can force e-liquid into the airflow chamber. This often causes: Gurgling Spitting Leaking from airflow holes Fix Leave a small air gap when filling your device. 2. Damaged O-Rings or Seals Rubber seals inside your tank prevent leaks. If they become damaged or loose, e-liquid can escape easily. Check For Torn rubber rings Loose pod connections Cracked tanks Damaged pods 3. Incorrect Coil Installation If the coil is not screwed in properly, e-liquid can seep into unwanted areas. Always ensure: The coil is firmly installed The pod clicks securely into place Threads are aligned correctly 4. Thin E-Liquid in High-Powered Devices Low VG liquids can leak more easily in powerful sub-ohm tanks because the liquid is thinner. E-Liquid Ratio Best For 50/50 Pod kits 70VG/30PG Sub-ohm vaping Using the correct VG/PG ratio helps prevent leaking. 5. Leaving Your Vape in Heat Heat thins the e-liquid and increases pressure inside the tank. This can force liquid out through the airflow system. Avoid Leaving Your Vape: In direct sunlight Inside hot cars Near radiators or heaters Quick Vape Troubleshooting Guide Problem Most Likely Cause Quick Fix Burnt vape taste   Dry or burnt coil Replace and prime the coil Weak flavour   Old coil Install a new coil Leaking tank   Overfilling Leave an air gap Gurgling sounds   Flooded coil Clean airflow chamber Weak vapour   Low battery Recharge device Harsh throat hit   High nicotine    strength Lower nicotine level Best Vape Maintenance Tips Replace Coils Regularly Do not wait until the coil tastes burnt before changing it. Keep Your Tank Clean Clean pods and tanks regularly to prevent residue build-up. Use the Correct Wattage Stay within the recommended wattage range for your coil. Avoid Chain Vaping Allow a few seconds between puffs to let the wick re-saturate. Store Your Vape Upright Keeping your device upright helps reduce leaking. Use Quality E-Liquids Poor-quality vape juice can shorten coil lifespan and reduce performance. Final Thoughts Experiencing vape problems like a burnt vape, weak vaping, or leaking tanks can be frustrating, but most issues are simple to diagnose and fix. In many cases, the solution comes down to: Replacing the coil Priming correctly Using the right wattage Matching the correct e-liquid to your device Maintaining your vape properly By understanding how your device works and following a few simple maintenance habits, you can improve flavour, extend coil life, and enjoy a more reliable vaping experience overall.
