Hayati Not Working? Charging Faults, E2 Errors and Burnt Taste
Most Hayati faults come down to four things, and three of them you can fix in a couple of minutes. Here they are in the order they are worth checking.
The device will not charge
Work through these in order — the first two account for most cases:
- Try a different cable and a different plug. A cable that still charges a phone can fail to charge a vape, so rule out the cable and plug before the device.
- Clean the port. Pocket lint compacts into the USB-C socket and stops the connector seating. Use a dry wooden toothpick or a blast of air. Never anything metal.
- Leave it on charge for a full hour even if nothing lights up. A deeply discharged lithium cell can take a while before it shows any sign of life.
If it still will not charge
Being straight with you: a lithium battery that has been fully flat for weeks, or one in a device that has had liquid leak into it, is usually not recoverable. There is no safe home fix, and advice you will find about jump-starting cells or bypassing the board is genuinely dangerous with a battery this size.
If the device is within its warranty period and was bought from us, contact support@hayativapes.uk before doing anything else.
Never post a device with a swollen, hot or leaking battery. Contact us and we will arrange safe disposal. Damaged lithium cells must not go through the postal system or into household waste.
The battery dies far too quickly
A battery that charges fine but runs flat in a few hours is a different fault from one that will not charge at all, and it usually is not the battery. Rule out these two first.
The device is firing in your pocket. Draw-activated devices can be triggered by pressure. If the body is warm when you take it out, or the pod is emptying faster than usual with no extra use, that is what is happening. Carry it upright, in its own pocket, away from keys.
You are chain-vaping without noticing. Long back-to-back draws pull far more power than short ones. The same device can last two days or half a day on identical liquid depending only on draw length.
If neither fits and the device is under a few weeks old, it is a genuine fault — see below.
E2 error on the screen
E2 means the device cannot read the pod. Work through these before assuming a fault:
- On ranges where the pod pulls straight off, pull it off and refit it firmly until it seats. On the Pro Ultra Plus 25000 nothing pulls off: see its own section below.
- Wipe the gold contacts on both the pod and the device with a dry tissue. Condensation or leaked liquid on the contacts can stop them connecting.
- Check the pod is the right one for your range — a pod from a different Hayati range can sit in place well enough to look right while failing to make contact.
- Try a second pod. If a known-good pod works, the first pod was faulty and we will replace it.
Hayati Pro Ultra Plus 25000: E2, one side not working, and charging
If you are asking why your Hayati Pro Ultra is not working, start here, because the Hayati Pro Ultra Plus 25000 is built differently from the rest of the range. A pack is the whole 22ml unit — a 2ml coil pod fed by two 10ml tanks that sit in a carrier at the top of the device — and nothing on it pulls straight up.
Hayati Pro Ultra E2 error
E2 means the device cannot detect the pod. Reseat the pack rather than pulling at it:
- Lift the mouthpiece and twist it to release the carrier.
- Lift the carrier clear of the body, with both tanks still in it.
- Check the contacts are clean and dry. A leaking tank can put liquid on them, and that stops the device detecting the pod.
- Drop the carrier back until it seats.
If E2 stays after that, try a new pack. If a fresh pack clears it, the old pack was the problem; if it does not, email support@hayativapes.uk with your order number.
Only one side of my Hayati Pro Ultra is working
Usually both sides work, and the screen has not caught up. Lifting and twisting the mouthpiece changes which tank feeds the pod, and the L or R on the screen changes after your next draw rather than as you turn it, so take one puff before deciding a side has failed. L is the tank on your left with the screen facing you.
If a side still will not feed after that, check the pack is seated: release the carrier, lift it clear and drop it back until it seats, with each tank in its colour-matched side.
E1 and other codes
We have not found an error-code list published by Hayati, so we will not guess what E1 or any other code means. If your Pro Ultra Plus 25000 shows one, reseat the carrier as above, then charge it. If the device is hot, swollen or leaking, do neither: stop using it and email support@hayativapes.uk. If a code stays after a reseat and a charge, email us with your order number and exactly what the screen shows.
Hayati Pro Ultra not charging
The Pro Ultra Plus 25000 has an 850mAh battery that charges over USB-C, so the checks at the top of this page apply to it unchanged: a different cable and plug first, then a clean, dry port. We do not give a charge time: we have not found one published by Hayati, and the figures other sellers quote disagree. If it takes no charge at all, email us before buying anything.
Burnt taste
Burnt taste has three distinct causes and the fix differs:
- New pod, burnt from the first puff. The wick was dry. Fit the pod, leave it upright for five minutes, then start with short gentle draws. Once a coil has been dry-fired it does not recover.
- Gradually got worse. The pod is near empty. Replace it.
- Fine, then suddenly burnt. Usually chain vaping — the wick has not kept up. Put it down for ten minutes and it will often recover.
No vapour, or a weak draw
Check the airflow holes are not blocked by pocket debris, make sure the pod is fully seated, and confirm the battery has charge. If the device fires — the light comes on — but produces nothing, the pod is the problem rather than the device.
Gurgling or liquid in the mouth
Usually caused by drawing too hard. These are mouth-to-lung devices designed for a gentle, cigarette-like pull, not a sharp lung hit. Draw softer and it generally settles. If it persists, tap the pod mouthpiece-down on a tissue to clear condensation.
When to contact us
Separately from us, a device that overheats, leaks onto skin, or makes you unwell can be reported to the MHRA through the Yellow Card scheme. That is the route regulators use to spot a bad batch across the whole market, and it is worth doing even after we have replaced the item.
If a device or pod fails within 30 days of delivery you can reject it for a full refund under the Consumer Rights Act — see our returns page. Email support@hayativapes.uk with your order number and a short description of what it is doing. Often we can sort it without you posting anything back.
These products contain nicotine, which is addictive. Over-18s only.
Replacing what has failed
Most of the faults above are the pod rather than the device, and a fresh pod is the cheapest test there is. We stock replacement pods for every range, and complete pod kits if the device itself has gone. On the Pro Ultra Plus 25000 a fresh pod means a whole pack, sold as 25K replacement pods; if a 25000 device has gone, you need the Pro Ultra Plus 25000 prefilled pod kit. Every flavour is listed in the Pro Ultra Plus flavour directory. If the item is still within its return window, do not buy a replacement — email us first and we will sort it.
Common questions
Why is my Hayati Pro Ultra not charging?
The Pro Ultra Plus 25000 charges its 850mAh battery over USB-C. Try a different cable and plug first, then make sure the port is clean and dry, because pocket lint can stop the connector seating. If it takes no charge at all, email us with your order number before buying a replacement.
Can I fix a dead battery on a Hayati Pro Ultra?
Usually not. A lithium cell that has been fully flat for weeks, or one in a device that has had liquid leak into it, is generally not recoverable. There is no safe home fix, and advice about jump-starting cells is genuinely dangerous at this size. If the device is under warranty, contact the retailer.
What does E2 mean on a Hayati vape?
E2 means the device cannot read the pod. On ranges where the pod pulls straight off, refit it firmly and wipe the contacts on the pod and the device with a dry tissue. On the Pro Ultra Plus 25000 nothing pulls off: lift the mouthpiece and twist it to release the carrier, lift it clear, check the contacts are clean and dry, then drop it back until it seats.
Why does my Hayati vape taste burnt?
If it is burnt from the first puff on a new pod, the wick was dry — let a new pod stand upright for five minutes before use. If it got gradually worse, the pod is near empty. If it was fine then suddenly burnt, that is usually chain vaping and it often recovers after ten minutes.
Why is my Hayati Pro Max not working?
Check the airflow holes are not blocked, that the pod is fully seated, and that the battery has charge. If the light comes on but no vapour is produced, the pod is at fault rather than the device.
