The Most Common IQOS and Vape Malfunctions and How to Fix Them

Smoke-free alternatives such as IQOS and electronic cigarettes have become increasingly common among adult smokers exploring an alternative to cigarettes. While these devices offer a smoke-free experience, they may sometimes face performance issues such as flavour disruption, vapour production failure, or battery-related faults. These are often a common issue, especially as devices age or if proper care is not followed.

In this guide, we explore some of the most IQOS and vape malfunctions, and offer practical tips for quick troubleshooting.

Understanding Malfunctions in Smoke-Free Alternatives

IQOS and vape devices are made up of several small, sensitive parts. These electronic devices work in sync to deliver nicotine without burning conventional cigarettes. Over time, or if not stored and cleaned properly, performance may decline.

Malfunctions can include a burnt taste, leaking tanks, blocked airflow holes, battery issues, or an IQOS pen not charging. Understanding the device's unique structure and using it within the recommended temperature range can help prevent disruptions.

IQOS Pen Not Charging: What to Do

If your IQOS pen doesn’t appear to be charging, you may be dealing with a dead battery, battery damage, or dirt obstructing the battery terminals. Make sure to use a manufacturer-approved power adaptor to avoid issues like battery drain. If the status lights don’t illuminate or a white light blinks unexpectedly, your device may require attention.

Also, check your Pocket Charger and make sure it has plenty of power left or is connected properly to a wall power outlet. If none of these methods help, it may be time for a battery replacement or a replacement device. In some cases, professional IQOS pen repair may be necessary to fix internal hardware issues.

Try the IQOS online diagnostic tool for self-service troubleshooting to quickly assess and resolve any issues with your device.

If you notice your battery performance declining over time, here’s why your e-cigarette battery may die faster than expected and what you can do to preserve its longevity.

IQOS Blade Breakage: Causes and Solutions

If you’re dealing with an IQOS broken blade, it's important to stop using the device immediately, as continued use may lead to further internal damage. Unfortunately, the blade cannot be repaired or replaced by the user, so the best solution is to contact IQOS customer support or visit an authorised service centre for a device replacement or upgrade.

Today, devices like IQOS ILUMA, IQOS ILUMA ONE, and IQOS ILUMA PRIME, eliminate the blade entirely by using a SMARTCORE™ Induction System. This not only removes the risk of breakage but also eliminates the need to clean the blade for tobacco debris, resulting in an overall easier and smoother experience.

Most Common Vape Issues and How to Fix Them

Common Charging Issues in Vapes and E-Cigs

Vape devices may encounter power issues due to faulty battery connections, aged components, or improper care. If the power button does not respond, inspect for connection issues, and use a cotton bud to remove any tobacco residue.

Improper handling, such as leaving your device exposed to direct sunlight or excessive heat, may further damage internal parts or shorten battery life.

In some cases, the issue may stem from a failing vape battery—one that no longer holds enough charge or distributes power inconsistently. Keeping the battery terminals clean and the device protected from heat sources can help prevent long-term degradation. In others, the problem may lie with a faulty charging port or a damaged USB cable.

Why Isn’t My Vape Producing Vapour?

A device that powers on but doesn’t produce vapour may be suffering from blocked airflow holes, an improperly primed coil, or a depleted e-liquid tank.

If you’re experience a vape without vapour issue, then these could be the main causes:

●       Battery Issues: A low charge, faulty connection, or broken charger can prevent the device from powering up or producing vapour.

●       Coil Problems: Burnt, clogged, or mismatched coils disrupt proper e-liquid heating and may require cleaning or replacement.

●       E-liquid Issues: Using too little, too much, or incompatible e-liquid can affect vapour production and device performance.

Troubleshooting guides like why your vape isn’t producing smoke explain how airflow, coil condition, and power levels can affect your vape’s output. Additionally, models like IQOS ILUMA eliminate many common mechanical issues through innovative heated tobacco devices that offer a smoother experience.

Vape Tank Problems

When a vape tank malfunctions, it can impact airflow, flavour quality, and liquid retention. Here is a list of common vape tank issues:

●       Vape Not Firing: The device doesn't activate when you press the power button, often due to a connection issue or faulty coil.

●       Vape Coil Issues: Burnt or faulty coils can lead to poor flavour, weak vapour, or harsh hits.

●       Leaking Vape: E-liquid may leak from the tank due to improper assembly, damaged seals, or overuse.

●       Overfilling Vape Tank: Filling the tank past its limit can cause flooding, gurgling sounds, or leaks.

●       Battery Issues: A weak or unresponsive battery can prevent the vape from working properly.

●       E-liquid Issues: Using the wrong type or low-quality e-liquid can damage the coil or affect performance.

●       Vape Spitting: The issue of vape spitting happens when hot e-liquid pops or splashes into the mouth, often caused by a flooded coil or excessive condensation.

Burnt Vape Taste: What It Means and How to Fix a Burnt Vape Coil

Experiencing a burnt flavour is often linked to a burnt vape coil. This happens when the wick inside the coil is dry or the device is used beyond recommended power levels. A vape battery that doesn’t deliver enough power can also result in uneven heating and dry hits.

If you've asked yourself, “why does my vape taste burnt with a new coil?”, the issue could be due to not priming the coil properly, using the wrong nicotine strength, or vaping at an incorrect wattage.

You can fix a burnt vape coil by following these steps:

●       Stop Vaping: As soon as you taste a burnt hit, stop using the device.

●       Check E-liquid Level: Refill the tank if the e-liquid is low.

●       Prime the Coil: For new or slightly burnt coils, soak the wick with e-liquid before use.

●       Lower the Wattage: Reduce the power setting to avoid overheating the coil.

●       Clean the Coil (if reusable):

○       Remove the coil and rinse under warm water.

○       Soak in white vinegar or alcohol for several hours.

○       Rinse again and let it dry completely.

●       Reassemble and Test: Reinstall the coil, prime it again, and test. If the burnt taste remains, replace the coil.

Burnt Vape Coils: Cleaning vs Replacing

If your coil is visibly dark or producing a bitter taste, you might attempt to clean it by soaking it in vinegar and letting it dry fully. However, this is often a temporary solution.

That’s because over time, residue from e-liquids—especially those with sweeteners or high vegetable glycerine content—can cause irreversible buildup on the coil and wick, affecting both vapour quality and flavour.

A saturated or burned wick may no longer absorb e-liquid properly, leading to dry hits or inconsistent performance. Additionally, cleaning may not fully restore the coil’s heating efficiency, meaning even after soaking, the device might continue to deliver a subpar experience.

For optimal results and safety, it's best to replace the coil according to your device manufacturer’s recommended schedule.

Why Does My Vape Taste Burnt With New Coil?

A burnt flavour from a new vape coil usually happens when the coil hasn’t been properly primed or if you’re vaping too frequently. Before using a new coil, it’s important to soak the wick thoroughly with e-liquid to avoid burning the dry cotton. Taking repeated puffs without giving the coil time to reabsorb e-liquid—known as chain vaping—can also cause the wick to dry out and result in that unpleasant burnt taste.

Preventing Device Issues Through Regular Maintenance

Preventing malfunctions is often a matter of basic care. Here is a list of regular vape and electronic cigarette maintenance tips:

●       Clean mouthpiece and tank weekly to prevent buildup.

●       Wipe battery contacts to ensure a stable connection.

●       Replace coils regularly if burnt or weak.

●       Store device upright to avoid leaks.

●       Don’t overcharge the battery.

●       Use compatible e-liquids only.

●       Keep device dry and dust-free.

When to Replace or Seek Support for Your Device

If your device continues to malfunction after basic maintenance, it's worth reaching out to a dedicated customer care team for assistance. Whether you're using a vape pen, heated tobacco device, or rechargeable vape, a persistent issue may require a replacement device.
