Crystal Pro Switch 30K Not Working? 10 Problems & Easy Fixes
The Crystal Pro Switch 30K is a high-performance prefilled pod kit with dual-flavour switching, a rechargeable battery, HD screen, and up to 30,000 puffs for long-lasting use. It’s built for convenience – no refilling, no coil changes, just replace the pod and keep vaping.
But like any vape device, you might eventually run into problems: the Crystal Pro Switch 30K not working, not firing, not charging, showing LED error flashes, tasting burnt, or giving weak vapour.
This guide walks you through 10 common Crystal Pro Switch 30K problems, why they happen, and step-by-step fixes you can try at home. If the device turns out to be at the end of its life, we’ll also explain when it’s better to replace the pod or the whole device.
What Is the Crystal Pro Switch 30K?
Before we jump into troubleshooting, it helps to understand what the device actually is.
The Crystal Pro Switch 30K (also described as Suonon Crystal Pro Switch 30K) is a dual-flavour prefilled pod kit with:
-
Up to 30,000 puffs
-
Dual-flavour pods so you can switch between two flavours in one device
-
Around 22ml of e-liquid in its dual-chamber pod system
-
0.8Ω dual mesh coil for smooth MTL vapour and rich flavour
-
HD LED / LCD screen showing battery, puff count and often e-liquid level
-
USB Type-C charging
-
Adjustable airflow, depending on the version/retailer
-
Typically 20mg (2%) nic salt in UK-compliant pods
Because it’s a prefilled pod kit, you don’t change coils or fill tanks. You simply use the prefilled pod, recharge the battery and replace the pod when it’s finished.
Now let’s fix it.
1. Device Not Firing (No Vapour on Inhale)
You inhale, but nothing happens – no vapour, no draw, maybe no LED. This is one of the most common Crystal Pro Switch 30K not hitting issues.
Common Causes
-
Low or flat battery
-
Pod not fully inserted or misaligned
-
Blocked airflow / auto-draw sensor (dust, condensation, liquid)
-
Dead or burnt coil inside the pod
-
Device has reached the end of its life (internal fault or heavily used)
Step-by-Step Fixes
-
Check the pod carefully
Remove the pod and inspect it for:-
Cracks or damage
-
Heavy leaking
-
Very low e-liquid
If the pod looks old or almost empty, it may simply be finished.
-
-
Reinsert the pod firmly
Push the pod fully down until it feels secure and “clicked” into place.
Poor contact between the pod and device is a frequent cause of no vapour. -
Recharge the battery fully
Connect the device to a USB Type-C charger via a reliable cable and wall plug (avoid very cheap cables or weak USB ports). Look for a battery or charging icon on the screen to confirm it’s actually charging. -
Clear the airflow
Check the mouthpiece and airflow slots for lint, dust or small droplets. Wipe them gently with a dry tissue or cotton bud. A blocked airflow sensor can stop the auto-draw system from activating. -
Try a new pod
If the screen lights up but still no vapour comes out, fit a fresh Crystal Pro Switch 30K pod. A dead coil or faulty pod will never fire properly, no matter how many times you try.
When to Replace the Device
You should consider replacing the full device if:
-
There is no LED / no screen activity even after a proper charge.
-
Multiple fresh pods still won’t fire.
-
The device has previously been dropped, crushed, or exposed to water.
At this point, it usually means an internal failure (board or battery) and repair isn’t realistic for a sealed prefilled kit.
2. Device Not Charging
Another common complaint: “Crystal Pro Switch 30K not charging”.
Common Causes
-
Faulty or low-quality USB-C cable
-
Weak or incompatible power adapter
-
Dust or fluff blocking the charging port
-
Over-discharged or damaged battery
-
Device overheating and refusing to charge for safety reasons
Step-by-Step Fixes
-
Check the charging cable & adapter
-
Try a different USB-C cable.
-
Use a proper wall charger instead of a laptop or TV USB port.
Many charging issues are caused by cables and plugs, not the vape itself.
-
-
Clean the charging port gently
Use a dry cotton bud or soft brush to carefully clear lint and dust from the Type-C port.
Don’t use water or alcohol – the port must stay dry. -
Confirm the LED / HD screen shows charging
When you plug it in, you should see:-
A battery icon moving or
-
A charging symbol on the HD screen.
If there’s zero response, test a different cable and plug before assuming the device is dead.
-
-
Try a different power source
Switch plug sockets or try another wall adapter with adequate output. Old phone chargers can sometimes be too weak. -
Let the device cool down
If the device feels warm or hot, unplug it and let it cool completely before trying again. Internal protections may block charging while the battery is too hot.
When to Replace the Device
If you’ve:
-
Tried more than one cable and adapter
-
Cleaned the port
-
Let it charge for at least 30 minutes
…and still get no charging icon, no LED, no response, then the internal battery or charging circuit is probably faulty. In that case, it’s best to replace the device.
3. Weak Vapour or Muted Flavour
The device still hits, but the vapour is thin and the flavour is weak or flat.
Common Causes
-
Low battery output
-
Old pod (coil + wick saturated with residue)
-
Chain vaping overheating the coil
-
Partially blocked airflow
-
Puffing either too softly (sensor doesn’t fully trigger) or too hard (flooding)
Step-by-Step Fixes
-
Check pod liquid levels
If the pod is nearly empty or the liquid looks very dark, performance will naturally drop. -
Replace a worn-out pod
Even in a high-capacity device, pods are still consumables. As the coil and wick age, flavour fades and vapour drops off. -
Slow down puffing
Leave 5–10 seconds between puffs.
This allows the wick to re-saturate with e-liquid and prevents overheating. -
Recharge the battery
A full battery provides much stronger and more stable power to the dual mesh coils, which improves vapour density and flavour. -
Clear the airflow
Wipe the mouthpiece and airflow slots. Condensation, tiny droplets and dust can restrict airflow and make the vapour feel weak.
When to Replace the Pod
Replace the pod if:
-
Flavour remains dull even with a full battery and clean airflow.
-
The pod has been used for a long time or is nearly empty.
A fresh Crystal Pro Switch 30K replacement pod will almost always restore performance.
4. Burnt or Harsh Taste
A burnt or harsh hit is one of the worst experiences you can get from a vape.
Common Causes
-
Burnt-out coil
-
Very low or empty e-liquid in the pod
-
Chain vaping (not letting the wick re-saturate)
-
Very hard inhales pulling liquid away from the coil
-
Flavour switched on a pod that was already nearly dry on one side
Step-by-Step Fixes
-
Check e-liquid levels
If one side of a dual-flavour pod is much lower than the other, the wick on that side may have dried out and burnt. -
Replace burnt pods immediately
Once cotton burns, the burnt taste will not go away, no matter how long you wait or charge the device.
Replace the pod – it’s the only solution. -
Slow down your puffing
Take moderate puffs and give the device a few seconds between hits. This prevents dry hits and keeps the coil from overheating. -
Switch flavours correctly
When you switch flavour using the dual-flavour system, take several gentle puffs to let the wick adjust to the new liquid. -
Recharge the device
Low power can sometimes cause uneven heating, which can make harshness more noticeable.
When to Replace the Pod
-
Any strong, persistent burnt taste
-
Pod is very low on liquid or the coil area looks dark/brown
At that point, continuing to use it just risks more harsh hits.
5. Leaking or Gurgling
Leaking and gurgling are very common complaints with any prefilled pod system, including the Crystal Pro.
Common Causes
-
Condensation build-up inside the chimney/mouthpiece
-
Over-inhaling and flooding the coil
-
Storing the device horizontally or in a hot environment (car, radiator, sunny window)
-
Damaged or faulty pod (poor seals, cracked plastic)
Step-by-Step Fixes
-
Clean the device thoroughly
Remove the pod and wipe:-
Pod base
-
Gold contacts
-
Inside of the pod chamber
Use a dry tissue or cotton bud to soak up any visible e-liquid.
-
-
Insert the pod securely
Make sure the pod is firmly seated and fully clicked in. Loose pods can leak more easily. -
Adjust your puffing technique
Avoid very hard pulls.
Gentle, steady inhales reduce flooding and gurgling. -
Store the device upright and away from heat
Standing the device vertically helps prevent liquid pooling in the airflow.
Avoid leaving it in hot cars or direct sunlight, which can thin the e-liquid and increase leaks. -
Replace the pod
If the pod keeps leaking even after cleaning, it may have a faulty seal or internal damage. Replace it.
When to Worry
Take extra care if:
-
You see liquid inside the main body near the screen or electrical components.
-
Leaking is combined with auto-firing, error messages or hot device temperature.
In those cases, it may be safer to stop using the device altogether.
6. Pod Not Detected / LED Error Flashes
Sometimes the Crystal Pro Switch 30K screen or LED starts blinking, and the device refuses to fire. This usually indicates a pod / connection issue or a safety cut-off.
What LED/Error Flashes Usually Mean
Different sellers and batches can vary slightly, but in general:
-
Blinking when inhaling → pod/connection/airflow issue
-
Blinking when plugging in → charging/battery issue
-
Rapid or continuous blinking → internal error or protection mode
Common Causes
-
Wet or dirty contacts from condensation or leaks
-
Pod not fully clipped into place
-
Non-compatible or damaged pod
-
Internal chipset or sensor fault
Step-by-Step Fixes
-
Remove & inspect the pod
Look for cracks, heavy leaks, or any obvious damage. -
Dry & clean the contacts
Gently wipe the gold pins on both the pod and inside the device with a dry tissue or cotton bud. -
Reseat the pod until it clicks
Make sure the pod is fully clicked in. A partial connection can trigger blinking and “pod not detected” behaviour. -
Clear the airflow
Clean the mouthpiece and airflow holes to ensure the auto-draw sensor can work correctly. -
Recharge the battery
Some faults clear once the device has enough power. -
Deflood the pod if you hear gurgling
Remove the pod, hold a tissue over the base and blow gently through the mouthpiece to push out excess liquid. -
Try a fresh pod
If only one pod causes blinking, that pod is probably faulty. Swap it for a new one.
When to Replace the Device
If:
-
You’ve tried multiple fresh pods
-
Cleaned and dried all contacts
-
Fully charged the device
…and it still blinks with no vapour, the internal chip or sensor may be damaged. At that stage, replacing the device is the safest option.
7. Auto-Firing or Device Heating Up (Safety First)
If your Crystal Pro Switch 30K starts auto-firing or heating up by itself, this is a serious safety issue.
Common Causes
-
Stuck or over-sensitive auto-draw/airflow sensor
-
Internal short circuit from leaked e-liquid
-
Damaged or faulty chip after drops, pressure or manufacturing defect
Step-by-Step Fixes
-
Remove the pod immediately
This stops power from going to the coil and stops further heating. -
Wipe and inspect the device
Check for liquid inside the pod chamber, around the screen or near the charging port. Clean gently with a dry tissue. -
Place the device somewhere safe to cool
Put it on a non-flammable surface (tile, metal tray, countertop) and let it cool completely. Don’t hold a hot device. -
Insert a fresh pod and test briefly
Only after it has fully cooled, test with a new pod. If the auto-firing started because of a leaking pod, a fresh one may solve it. -
If the problem persists without a pod → replace the device
If the device heats up or behaves strangely even with no pod inserted, it indicates an internal fault. Do not keep using or charging it.
Safety Tip
Never continue to vape or charge a device that:
-
Auto-fires
-
Feels unusually hot
-
Smokes or smells burnt from inside the body
Dispose of it safely and switch to a new, reliable device.
8. Airflow Too Tight or Too Loose
The draw on your Crystal Pro Switch 30K suddenly feels too restricted or far too airy.
Common Causes
-
Condensation or debris in the airflow path
-
Slight differences in pod design between batches
-
Switching from another device with very different MTL/RDL feel
The Crystal Pro Switch line is known for its smooth MTL draw and sometimes includes adjustable airflow, but small changes in pod or user expectations can make it feel “off”.
Step-by-Step Fixes
-
Check for blockages
Inspect the mouthpiece and airflow holes for lint, dust, dried liquid or condensation. Clean them gently with a tissue. -
Reinsert the pod
A slightly misaligned pod can affect airflow. Remove it and reseat it firmly. -
Clear condensation
If you see tiny droplets in the mouthpiece, wipe them away and gently blow through the pod into a tissue. -
Adjust your puffing technique
-
For tight airflow: take slower, more relaxed inhales.
-
For loose airflow: take shorter puffs and control the draw.
-
-
Try a fresh pod
Different pods can feel slightly different due to manufacturing tolerances. A new pod often restores your preferred draw.
When to Replace the Device
If the body is cracked, warped, or physically damaged around the airflow area – or airflow issues come along with leaks, errors or auto-firing – it might be more than a pod problem and time to upgrade.
9. Battery Draining Faster Than Expected
You may feel your Crystal Pro Switch 30K battery life isn’t as good as it used to be.
Common Causes
-
Very heavy or frequent use (long and repeated puffs)
-
Using higher power modes where applicable
-
Natural battery degradation over time
-
Extreme heat or cold
-
Pod faults causing extra power draw (internal short, leak)
Step-by-Step Fixes
-
Moderate your vaping style
Take shorter puffs and avoid constant chain vaping. This reduces power consumption. -
Fully charge before extended use
Let the device reach a complete charge instead of just quick partial top-ups. -
Use normal / standard mode
If there are power or flavour modes, use standard rather than max power to extend battery life. -
Keep the device at room temperature
Avoid leaving it somewhere extremely hot or cold. Batteries perform best in moderate conditions. -
Check for pod issues
If a pod is leaking or internally damaged, it can cause inconsistent performance and may drain the battery faster. -
Replace the device if the battery is clearly worn out
If your device only lasts a couple of hours with light use, and it used to last much longer, the battery is likely at end-of-life. Because it’s a sealed kit, the only fix is to replace it.
Battery Life Expectation
Depending on how you vape, a 30,000-puff, 850mAh rechargeable device is expected to last days to weeks of typical use, not months or years. Heavier vapers will go through the life cycle faster than light users.
10. Flavour Tastes Mixed After Switching (Dual-Flavour Pods Issue)
A headline feature of the Crystal Pro Switch 30K is its dual-flavour system – two flavours in one pod, switchable via a button or toggle.
Some users report that after switching, the flavour tastes mixed, muddy or not clear.
Common Causes
-
Both flavours share the same coil / chamber system (even if the chambers are separate)
-
The wick retains some of the previous flavour
-
Switching flavours too quickly back and forth
-
Expecting a “hard cut” between two very different flavours
Step-by-Step Fixes
-
Fully engage the flavour switch
Make sure the flavour selector is fully moved to the new position and not left in between. -
Take several puffs after switching
Give the wick 3–6 puffs to clear out the previous flavour and let the new one dominate. -
Clear the airflow
Clean the mouthpiece and chimney to remove any residual condensation that may carry old flavour. -
Use fresh pods for the cleanest flavour
Older pods often have more flavour mixing because the wick has been exposed to both flavours for a long time. -
Manage expectations – some overlap is natural
With any dual-flavour pod sharing a coil or chamber, a small amount of flavour overlap is normal. The system is designed for convenience and variety, not lab-grade separation.
When to Replace the Pod
-
Flavour remains permanently muddy or unpleasant, even after several puffs.
-
Pod is old, heavily used, or nearly empty.
A fresh pod will give the clearest taste experience.
When to Replace the Crystal Pro Switch 30K Completely
Sometimes it’s more efficient – and safer – to stop troubleshooting and replace the kit.
You should seriously consider replacing the whole device if:
-
There’s no LED or screen response after proper charging and cable checks.
-
It has severe leaks into the body or overheating / auto-firing.
-
It consistently fails to detect multiple fresh pods.
-
It has been dropped in water or suffered serious physical damage.
At that point, the cost and risk of continuing to use it outweigh the price of a replacement.
When you do replace it, you can:
-
Get a new Crystal Pro Switch 30K kit
-
Pick up Crystal Pro Switch 30K prefilled pods for your existing device (if only pods were the issue)
-
Or explore similar prefilled pod kits if you prefer single-flavour simplicity.
Conclusion
Most “Crystal Pro Switch 30K not working” problems are caused by:
-
Simple contact, airflow or pod issues
-
Low battery
-
Normal coil wear and pod ageing
-
Condensation or minor leaks
By following the step-by-step fixes in this guide, you can usually solve issues like not hitting, not charging, weak vapour, burnt taste, leaks, blinking lights, and mixed flavours without much hassle.
When you start to see serious symptoms – like auto-firing, overheating, no power at all, or constant errors with multiple pods – that’s your signal that the device is nearing the end of its safe lifetime. At that point, replacing the kit with a fresh Crystal Pro Switch 30K or another trusted prefilled pod system is the best move for both performance and safety.
