Got a gurgling noise when you inhale on your e-cigarette? Or simply not getting much vapour (but without the burned taste that goes with a burnt out coil?)
You probably have a flooded coil.
The good news is that flooded coils are easy to clear, and you should be back to vaping in no time.
What causes a flooded coil?
1. Drawing too hard on some devices can lead to flooding, as the coil becomes over saturated.
2. Not replacing coils. As coils age, they can lose their ability to absorb e-liquid.
3. Using too low a power level for your coil. When you do this, the coil is not receiving enough power to properly vapourise the e-liquid. If provided, follow the recommended wattage guidelines on the instructions that come with your vape device.
4. Filling your tank incorrectly. When filling a tank with an open center tube, ensure that the e-liquid goes down the side of the tank, and not down the center tank.
5. Damaged o-rings. If these are damaged or slip out of position it can cause flooding.
How to Clear a Flooded Coil
There are numerous ways to clear a coil, but we are sticking to the simplest ways here.
1. Turn it upside down and leave to drain.
2. Remove the tank from your device and the coil from your tank, and blow through the coil to clear some of the e-liquid out. (One of our customers sucks the e-liquid out with a baby aspirator. (Presumably her children now no longer require the aspirator!)
3. Remove your tank, fire up the device and burn off the excess e-liquid. (But be careful not to burn out the coil.)
4. Replace the o-rings. Many tanks now come with replacement o-rings. If other methods fail, it’s worth checking these and replacing them if they are damaged.
5. Remove the tank and clean with hot (but not boiling water). Once you have done this, it’s important to ensure your coil is completely dry before using again.
Bonus method: This comes from Stewart Olliphant on our Facebook page:
Handy hint, if your atomiser for the tank stops working, try using a steredent tablet in a cup of water, leave over night, flush with clean water, bingo, like new, it takes a few drags to return to normal as you need to flush the water through, but it’s worked for me and revitalised my atomisers!

Change your tank
If you have a persistent problem with flooding, it may well be worth changing the tank you use. Many modern tanks are designed to minimise the chances of flooding.
For example, the Innokin Zenith D22 is an easy-to-use tank which automatically cuts off internal airflow when you fill your tank to reduce the risk of flooding, while the TECC Arc 5S kit has a dedicated filling port which eliminates chances of mis-filling the device.
Coils – they don’t last forever!
Simply put, vape coils don’t last forever, and sooner or later your coil will simply give up the ghost and die. Signs of a deteriorating coils can be:
- decreasing amount of vapour
- strange or burnt taste
- just not working!
Fortunately, most devices come with replaceable coils now. To extend the life of these as long possible, always prime the coil first (ensuring that the cotton in the coil is saturated before you vape it). When vaping, always ensure that the coil is covered in e-liquid to ensure it doesn’t dry out and burn.
