If you still haven’t gotten around to buying a spare JUUL® battery, a JUUL® that isn’t hitting is a serious problem. Well, we’ve got some good news for you. The JUUL® device may be small, but it’s built like a tiny tank. Unless the battery no longer holds a charge, it’s likely that you can get your JUUL® device working again without too much trouble. If your JUUL® device isn’t producing vapour, follow these steps to get your device back in good working order.

We’re going to fix your JUUL® device that isn’t hitting by working through potential solutions to the problem in order from the simplest to the most complex solutions. If one solution doesn’t get your JUUL® producing vapour again, simply move on to the next one. We’re going to show you how to:

  • Diagnose a dead battery
  • Check for a faulty or empty pod and clear a vacuum lock that can prevent e-liquid from flowing
  • Remove e-liquid and residue that can prevent the JUUL® device’s airflow sensor from detecting your puffs
  • Disassemble your JUUL® device to remove deep residue if all else fails


Before spending too much time troubleshooting a JUUL® that isn’t hitting, connect the battery to the charger and ensure that the LED begins to pulse. If your JUUL® device isn’t charging, you may need to troubleshoot that issue instead. Tap the LED twice. If the light flashes green, the battery is fully charged already.


The JUUL® battery is an e-cigarette that has built-in temperature control functionality. If the wicks in the pod are dry, you won’t get a burned hit; you’ll simply get no vapour at all. Remove the pod and check it. Is it empty? Time for a new pod. If the pod isn’t empty, air bubbles around the wicks might be preventing the e-liquid from flowing through as it should. Tap the pod a few times to break the bubbles. Still having problems? Try a different pod.


Your JUUL® device probably spends a lot of time in your pocket. In addition, though JUUL® pods do have excellent quality control, you may occasionally encounter one that leaks. If your JUUL® battery is fully charged – and it isn’t hitting with any pod – it’s likely that e-liquid, pocket lint or some other contaminant is either preventing the pod from making a good connection with the battery or preventing the JUUL® device from detecting your puffs.

Start by attempting to clear the blockage with air pressure. Cover the hexagonal windows on the sides of the JUUL® with your finger and thumb. Puff firmly. Does the LED come on? If it does, puff a few more times before checking to see if you can use the JUUL® device normally. If it still doesn’t work, remove the pod. Place your mouth over the bottom (charging end) of the battery and blow firmly. Check the top of the battery. Do you see e-liquid around the metal pins? Soak it up with a cotton swab. Continue blowing through the battery and cleaning the pins until you no longer see e-liquid.

If your JUUL® device still isn’t hitting, a more thorough cleaning may be in order. Hold the JUUL® battery upside down and use a cotton swab to push the pins in. Hold the cotton swab there for several seconds before removing it from the battery. Can you see e-liquid on the cotton swab? Keep going until the cotton swabs come out dry.

If your JUUL® device doesn’t produce vapour after the quick cleaning, a more thorough cleaning may be in order. Dampen a cotton swab with a small amount of rubbing alcohol and use it to clean all around the pins at the top of the JUUL® battery. Allow the battery to dry and try using it again. If your JUUL® still isn’t hitting, a bit of surgery may be necessary.


Note: The JUUL® device isn’t meant to be serviced by the end user. Disassembling your JUUL® device could quite possibly render it permanently inoperable if you make an error. We provide these instructions for informational purposes only and take no responsibility for any mishaps that may occur.

If you’re certain that your JUUL® battery still holds a charge – the LED lights up, but the JUUL® device doesn’t hit regardless of what you do – and none of the above steps successfully resolve the issue, a deeper cleaning might get your JUUL® device working again. At the top of the JUUL® device, a rubber dam helps to prevent e-liquid from reaching the innards of the device. If e-liquid happens to get past the dam, removing it is exceptionally difficult. We’re going to show you how to take a peek at what’s going on under there.

To disassemble the JUUL® device, you need a pointy tool such as a pin and a blunt tool such as a thin flat-head screwdriver. Use the pin to push the JUUL® LED under the device’s metal casing while simultaneously inserting the screwdriver in the top of the JUUL® device and pushing gently to guide the device’s mainboard and battery out of the bottom of the casing.

At the top of the mainboard, you’ll see the rubber barrier around the pod contact pins. Remove the barrier. Check for e-liquid and residue around the pins and the small round puff sensor near the LED. Clear away any grime with a cotton swab. Replace the rubber barrier and push the mainboard back into the JUUL® casing.

Once you’ve reassembled your JUUL® device, it should work as normal. Cleaning leaks promptly can help to prevent e-liquid from getting past the barrier in the future.
