Vape Popping Problems Explained: How to Fix Bubbling, Crackling, and Spitting

VAPORESSOVAPORESSO

Vapers often notice small popping or bubbling sounds when they inhale, and this is usually part of normal coil activity. However, when the noise becomes louder than usual, or the device starts pushing droplets of e-liquid into the mouthpiece, it may point to an underlying issue.


This guide explains what causes vape popping, bubbling, crackling, and spitting, and outlines practical ways to solve these issues so you can maintain a clean, smooth, and consistent vape experience.



Why Is My Vape Bubbling?


Bubbling happens when you hear a gurgling sound coming from the pod or tank. It often occurs due to excess liquid in the tank, usually caused by overfilling, built-up condensation, or airflow that has been partially blocked by trapped liquid.


Effects


When bubbling starts, you may notice reduced vapour, a tighter or less satisfying draw, and early signs of spitting as the coil heats unevenly. Even though bubbling is common, it’s best to address it early to keep your device working smoothly.


Quick Fix Tips:


Here is how to fix the vape bubbling:

  • Avoid filling the tank or pod beyond the marked line
  • Check that the airflow holes are open and free of moisture.
  • Blow gently through the mouthpiece or remove the pod to clear any trapped liquid.

Why Is My Vape Crackling?


Crackling refers to the small vape popping or hissing sounds you hear when e-liquid comes into contact with a heated coil.


A gentle crackle is completely normal and simply indicates that the liquid is being vaporised. However, when the sound becomes unusually loud, uneven, or persistent, it often points to an issue with how the coil is heating the e-liquid.


Common causes include:

  • A coil that has taken in too much liquid and is starting to flood
  • Wattage settings that do not match the recommended range for the coil
  • High-VG e-liquids that move slowly through the wick and vaporise unevenly

However, you can solve these vape popping problems with some simple measures, such as:


Solutions

  • Adjust your wattage so it aligns with the coil’s recommended range.
  • Use an appropriate VG/PG ratio for your device.
  • Use a higher wattage setting to speed up the vaporisation process.
  • Replace an ageing or saturated coil if noise continues.

Why Is My Vape Spitting?


Spitting happens when droplets of hot e-liquid shoot up through the mouthpiece instead of turning fully into vapour. This usually means the coil is receiving more liquid than it can evaporate at that specific moment.


Causes

  • Severe coil flooding that oversaturates the wick
  • Condensation buildup inside the chimney or mouthpiece
  • Low-temperature vaporisation that occurs when the device wattage is set too low

Risks


Spitting creates an unpleasant mouthfeel and interrupts the smooth draw most users expect. It also weakens the overall vapour quality because the coil cannot maintain steady evaporation when excess liquid is present.


Over time, repeated flooding and exposure to unvaporized e-liquid can place extra stress on the coil, causing it to degrade sooner than expected.


Fixes

Vape spitting can be avoided in the following ways:

  • Fire the device briefly before inhaling to evaporate excess liquid
  • Increase the wattage slightly to help the coil reach an efficient vaporisation temperature.
  • Replace the coil or cotton if it has become oversaturated or worn
  • Keep the device upright so liquid does not collect where at unwanted placed


Recommended Device: Vaporesso XROS Pro 2


If you want a device that naturally reduces vape popping, bubbling, and spitting, the Vaporesso XROS Pro 2 offers several advantages, thanks to its upgraded design and heating technology.

  • COREX 3.0 Heating Technology: Provides more even heat distribution, reducing the chances of flooding, vape popping, or hot droplets reaching the mouthpiece.
  • Consistent Output with Super Pulse Mode: Keeps power delivery steady during each puff, preventing the unstable heating that leads to loud crackling or spitting.
  • Optimised Airflow System: Helps maintain proper air movement around the coil, lowering the likelihood of bubbling or gurgling inside the pod.
  • 2000mAh Long-Lasting Battery: Supports stable performance across long sessions, ensuring the coil stays within an efficient temperature range.
  • 0.96” TFT Screen with Clear Controls: Lets users adjust power precisely, which helps avoid low wattage conditions that typically cause spitback.
  • Smart Puff Tracking and Usage Insights: Helps identify patterns like taking very short puffs, which often lead to condensation buildup.

My first device was a disposable vape, not a good fit but it inspired me to look out for new alternatives. 5 years experiences testing new vape devices, recording and sharing online. I believe that there should be no vaping among young people and non smokers, but, smokers should try vaping as an alternative.
