The Hayati Pro Ultra 25000 has quickly become a popular choice for vapers. It offers an incredible puff count, a rechargeable battery, and an innovative dual-flavour system. This makes it a significant upgrade from standard disposable vapes.
However, like any electronic device, it can sometimes run into issues. You might find your Hayati Pro Ultra 25k not working, tasting burnt, or failing to charge. The good news is that most of these problems are easy to fix.
This guide will walk you through the most common problems and provide simple, step-by-step solutions to get your device working perfectly again.
Top 5 Common Problems and Solutions
Even the best devices can have off days. Here are the most frequent issues users report with the Hayati 25k and how to troubleshoot them.

1. Device Not Firing (No Vapour on Inhale)
This is the most common issue: you take a puff, but nothing happens. No vapour, no sound, no light. Don't worry, the fix is usually simple.
Common Causes:
- Dead Battery: The 850mAh battery is simply out of charge.
- Poor Pod Connection: The pod isn't seated correctly, or the connectors are dirty.
- Empty Pod: The e-liquid in one or both tanks has run out.
- Blocked Airflow Sensor: Debris might be blocking the sensor that detects your inhale.
Step-by-Step Fixes:
- Recharge the Battery: Connect your device to a USB-C charger. A full charge takes about 45-60 minutes. The smart screen will show the battery level.
- Reseat the Pod: Remove the pod from the device. Wipe the gold magnetic connectors on both the pod and the device with a dry tissue. Reinsert the pod firmly until you feel it click into place.
- Check E-Liquid Levels: Look at the transparent pod. If it's empty, it's time to replace it with a new Hayati Pro Ultra Plus pod.
- Clear the Airflow: Check the small airflow holes on the device. Make sure they aren't blocked by your fingers or lint. A gentle blow can help clear them.
2. Burnt or Harsh Taste
A burnt taste can ruin your vaping experience. It's crucial to distinguish between a "dry hit" and a "burnt hit." A dry hit is temporary, but a burnt hit means the pod's coil is permanently damaged.
Common Causes:
- Empty Pod: The most common reason. Vaping on an empty pod scorches the cotton wick.
- Chain Vaping: Taking too many puffs in a row doesn't give the wick time to re-saturate with e-liquid.
- Low Battery: An underpowered battery can heat the coil unevenly, leading to a harsh taste.
Once a pod tastes burnt, the flavour will not recover. The only solution is to replace the pod. Continuing to use a burnt pod is unpleasant and may irritate your throat.
How to Fix and Prevent It:
- Replace the Pod: If you get a persistent burnt taste, swap the pod for a new one immediately.
- Pace Yourself: Wait 15-20 seconds between puffs. This allows the wick to absorb more e-liquid, preventing dry hits.
- Keep it Charged: Ensure your device has enough battery power for consistent heating.
3. Device Not Charging
If you plug in your Hayati Pro Ultra and the screen doesn't light up, there's a charging issue. This prevents you from using the device at all.
Common Causes:
- Faulty Cable or Adapter: The USB-C cable or the power source might be the problem.
- Dirty Charging Port: Dust or debris can block the connection in the USB-C port.
- Device Needs a Rest: If the device is hot, its safety features may prevent it from charging.
Step-by-Step Fixes:
- Check Your Gear: Try a different USB-C cable and a different wall adapter. A stable 5V adapter is recommended.
- Clean the Port: Carefully inspect the charging port. Use a dry cotton swab or a toothpick to gently remove any lint or residue.
- Let it Cool Down: If the device feels warm, unplug it and let it rest for 10-15 minutes before trying to charge again.
4. Weak Vapour or Muted Flavour
Sometimes the device works, but the vapour is thin and the flavour is weak. This usually indicates the pod is nearing the end of its life or the battery is low.
Common Causes:
- Low Battery: A nearly drained battery can't produce enough power for dense vapour.
- Pod is Almost Empty: As e-liquid runs low, the wick doesn't get fully saturated.
- Blocked Airflow: Obstructed airflow holes can lead to thin vapour.
How to Fix It:
- Recharge Fully: A full battery ensures optimal power output.
- Check the Pod: If the e-liquid is low, it's time for a replacement pod to restore rich flavour.
- Ensure Clear Airflow: Double-check that the air inlets are not covered while you vape.
5. Blinking LED Lights or Error Messages
Blinking lights or on-screen errors are the device's way of telling you something is wrong. For Hayati devices, this often points to a pod detection issue.
Common Issues and Meanings:
| Blink Pattern / Error | Potential Cause | Solution |
|---|---|---|
| 3-4 Blinks or "Pod Not Detected" | Pod is not making proper contact. | Remove, clean contacts, and firmly reinsert the pod. |
| 5+ Blinks or "E2 Error" | Short circuit or atomizer issue. | Clean contacts, try a new pod. If it persists, the device may be faulty. |
| Light blinks during puff | Low battery. |
Recharge the device. |
Most blinking errors are resolved by ensuring a clean and secure connection between the pod and the device.
