This is the single most common reason a vape stops working. Your battery may have enough charge to illuminate the LED indicator but not enough to heat the coil and produce vapour—especially in colder weather, which reduces battery performance in all lithium-ion devices.
Signs your battery is the problem: the light blinks rapidly when you inhale, the device fires weakly for one or two puffs then stops, or the device refuses to fire at all despite showing a charge indicator.
- Plug your device into a charger using the correct cable (USB-C for most modern devices).
- Charge for a minimum of 30–45 minutes before testing.
- If possible, try a different cable and/or charging port—the cable is often the culprit.
- Once charged, turn the device on (usually 5 rapid button clicks) and attempt to fire.
- If using a mod with removable 18650 or 21700 batteries, remove and recharge them in an external charger.
All modern UK-compliant vape devices include safety features to prevent accidental firing—particularly important when a device is loose in a bag or pocket. If your device is locked, it simply won’t fire even when fully charged.
Safety cutoffs also trigger automatically if your device has been fired continuously for more than 10 seconds, if the atomiser resistance is out of the acceptable range, or if the battery voltage drops too low.
- Unlock the device: on most button-activated vapes, press the fire button 5 times rapidly in under 2 seconds. Some devices use 3 clicks or a dedicated lock switch.
- Look for a lock icon on the screen (if your device has one) to confirm it is unlocked.
- If a cutoff has triggered, wait 10–15 seconds then try again.
- If your screen shows “Check Atomiser” or “No Atomiser”, proceed to Fix 3.
- Consult your device’s manual for the exact unlock sequence if in doubt—or visit any 888 Vapour store for a quick demonstration.
Common Vape Problems at a Glance
Use this table for a rapid diagnosis before working through the detailed fixes below.
| Symptom | Most Likely Cause | Urgency | Likely Fix |
|---|---|---|---|
| No response at all (no light, no sound) | Dead battery or device locked | Medium | Charge fully; try 5-click unlock |
| Light flashes, no vapour | Low battery, safety cutoff, or connection issue | Medium | Charge; reseat pod/tank |
| Light on, poor/weak vapour | Blocked airflow, dying coil, or low battery | Low | Clean airflow; check coil |
| Burnt or harsh taste | Burnt coil or wicking cotton | Medium | Replace coil immediately |
| Gurgling, spitting hot liquid | Flooded coil or airway | Medium | Clear airway; fire without inhaling |
| “Check Atomiser” / “No Atomiser” | Poor connection between coil/pod and battery | Medium | Remove and refit pod; clean contacts |
| Device won’t charge | Faulty cable, dirty port, or dead battery | Medium | Try new cable; clean port gently |
| Auto-firing (fires by itself) | Stuck fire button or internal short | High — stop using immediately | Remove battery if possible; discontinue use |
Your device needs a solid electrical connection between the battery and the coil inside your pod or tank. Even a thin film of e-liquid on the metal contacts, or a pod that isn’t seated quite straight, can interrupt this connection entirely. This is the second most common cause of a vape that “lights up but won’t hit.”
- Remove the pod or tank completely from the battery section.
- Look at the metal contact points on both the pod base and the top of the battery—wipe them gently with a dry cotton bud or piece of kitchen roll.
- If there is stubborn e-liquid residue, a tiny amount of isopropyl alcohol on the cotton bud works well; allow it to evaporate for 60 seconds before reassembling.
- Reinsert the pod or tank firmly and squarely. Most magnetic pod systems give a satisfying click or pull when correctly seated.
- Fire the device. If you have a screen displaying “No Atomiser”, try a fresh pod or coil to determine if the existing one is faulty.
Your vape uses either a button or draw-activation to fire. Draw-activated devices (which fire automatically when you inhale) rely on a tiny airflow sensor to detect suction. If the airflow is blocked—by pocket lint, dust, condensation, or e-liquid—the sensor can’t detect your inhale and the device simply won’t fire.
Similarly, even on button-activated devices, a fully closed airflow ring or a blocked mouthpiece means you’ll get a tight, uncomfortable draw with little or no vapour production.
- Check your airflow ring or slider and make sure it is open (fully or to your preferred setting).
- Inspect the mouthpiece and any visible airflow holes for blockages. A piece of rolled kitchen roll can clear most blockages.
- Remove the pod or tank and blow gently but firmly through the bottom airflow inlet—you should feel free airflow through the mouthpiece.
- For draw-activated devices: remove the pod and blow a short, sharp breath directly into the airflow sensor area, then refit and test.
- If condensation is visible inside the mouthpiece, clear it with a dry cotton bud.
Every vaper will experience a burnt hit at some point. That harsh, acrid taste that hits the back of your throat is your coil’s cotton wicking material burning, rather than e-liquid vapourising. It’s unpleasant, but it’s also a very clear signal from your device.
Common causes of a burnt coil: chain vaping (taking too many puffs in quick succession, not giving the wick time to re-saturate), running the tank too low on e-liquid so the wicking holes are exposed to air, using a wattage setting that is too high for the coil, or simply using the coil beyond its lifespan (usually 1–3 weeks depending on usage).
- Stop vaping immediately—continuing to hit a burnt coil damages it permanently and produces unpleasant compounds.
- If the coil is replaceable, swap it for a fresh one.
- When fitting a new coil, always prime it first: add 3–5 drops of e-liquid directly onto the visible cotton wicking holes and into the top of the coil. Fill the tank and then wait 5–10 minutes before vaping.
- For pre-filled pods, the entire pod must be replaced.
- Start at the lower end of the coil’s recommended wattage range and gradually increase if needed.
If your vape gurgles, spits hot liquid into your mouth, or produces a wet, crackling sound when you fire it, the coil has flooded—too much e-liquid has saturated the cotton and pooled in the coil chamber. This often happens after overfilling, leaving the device on its side, or inhaling too gently on a pod kit.
- Remove the pod or tank from the battery.
- Hold a piece of kitchen roll over the base of the pod/coil and gently blow from the mouthpiece end—excess liquid will drain onto the paper.
- Refit the pod/tank and fire the device 2–3 times without inhaling. This burns off the excess liquid. You will see vapour or hear a clearing sound.
- Take a gentle, slow draw. The gurgling should have cleared.
- If flooding persists, the coil may have reached the end of its lifespan and needs replacing.
This applies to devices with adjustable wattage: box mods, advanced pod mods, and sub-ohm kits. Every coil has an optimal wattage range, usually printed directly on the coil itself or on its packaging. Firing at too low a wattage means the coil never reaches the temperature needed to vaporise e-liquid properly. Too high and you’ll burn the cotton instantly.
- Locate the wattage range printed on your coil (e.g., 0.4Ω = 25–35W; 0.8Ω = 12–18W).
- Set your device to the lower end of this range to start.
- Increase in increments of 2–3W, testing as you go, until flavour and vapour production are satisfactory.
- If your device’s wattage has been accidentally changed (easy to do in a pocket), reset to the correct range.
Sometimes the device is working perfectly—but the e-liquid is causing the problem. This is particularly relevant for vapers who have recently switched from cigarettes and aren’t getting the nicotine satisfaction they expected.
Nicotine Strength
In the UK, all nicotine e-liquids are capped at 20mg/ml (2%) under TRPR regulations enforced by the MHRA. Available strengths from UK retailers are typically 3mg, 6mg, 10mg, and 20mg. If you’re a recent ex-smoker not getting a satisfying hit, try stepping up to a higher strength or switching from freebase nicotine to nicotine salts (nic salts), which deliver nicotine to the bloodstream more rapidly and smoothly—mimicking the feel of a cigarette more closely.
PG/VG Ratio
E-liquid is a blend of Propylene Glycol (PG) and Vegetable Glycerine (VG). Higher PG (e.g., 50:50) gives a stronger throat hit and more flavour intensity. Higher VG (e.g., 70:30 or above) produces bigger clouds but a smoother hit. Very high-VG liquids can be too thick to wick properly in small pod systems, causing dry hits. For pod kits, a 50:50 ratio is generally optimal.
Check Your Tank Isn’t Empty
It sounds obvious, but an empty tank is one of the most common causes of a dry hit or no vapour. Most pod kits have a translucent window to check liquid level—keep it above the coil’s wicking holes at all times.
If your device won’t charge at all—no indicator light when plugged in, no response whatsoever—the charging port may be dirty, damaged, or the cable may be faulty. Pocket fluff accumulating in USB-C ports is surprisingly common and easily fixed.
- Inspect the charging port with a torch for visible debris. Use a dry wooden toothpick or soft brush to gently remove any lint—never use metal objects.
- Try a different USB-C cable. Cheap or damaged cables are a very frequent cause of charging failure.
- Try a different power source (different USB port, plug adapter, or power bank).
- Avoid fast-charging adapters—vape batteries are small and benefit from standard 5V/1A or 5V/2A charging.
- If none of the above works and the device is relatively new, the port may be damaged and the device should be replaced.
When to Replace Your Device: 8 Warning Signs
Most vape problems are fixable, but some devices have reached the end of their lifespan and no amount of troubleshooting will resurrect them. Here are the clear signals it’s time for a new device:
| Warning Sign | What It Means | Action |
|---|---|---|
| Auto-fires continuously | Stuck fire button or internal short circuit | Stop using immediately |
| Battery swollen or bulging | Battery failure—potential fire risk | Dispose safely at council recycling |
| Won’t charge after multiple cables tried | Dead battery or irreparably damaged port | Replace device |
| Screen dead after overnight charging | Internal battery failure | Replace device |
| Burnt taste with new coil + correct wattage | Damaged connection point or mod fault | Replace device |
| Visible cracks in battery casing | Compromised structural integrity | Stop using immediately |
| Gets dangerously hot (not just warm) | Battery or electrical fault | Stop using immediately |
| Charging port physically broken | Cannot be charged or repaired at home | Replace device |
