How to Troubleshoot a Lost Mary TP800 That Won’t Fire

A Lost Mary TP800 that won’t fire usually points to a small number of areas: battery power, charging, pod detection, airflow or a safety lockout. Begin with the least invasive checks, keep the unit away from heat and flammables, and stop immediately if the battery is swollen, wet, scratched, unusually hot or giving off a chemical smell. Do not prise the body open, bend the contacts or bridge them with metal.

Australian buyers should check the device and refill situation before troubleshooting. Vapes are generally sold only through licensed retailers, and the product should appear on the TGA’s Australian Register of Therapeutic Goods. Disposable vapes cannot legally be sold in Australia, while personal imports are restricted. Pharmacists can supply nicotine vapes to eligible adults with a valid prescription. In local vape-shop language, pods are often called “top-ups”, while a device with no remaining charge may be called flat.

Nicotine warning: Nicotine is addictive and is not safe for children or adolescents. Keep pods, devices and e-liquid away from people who cannot access them. If someone swallows liquid or develops symptoms such as vomiting, dizziness, sweating or confusion, call Poisons Information Centre on 13 11 26; call 000 for severe breathing problems or unconsciousness.

Check the basics first

Start by identifying the exact symptom. Does the TP800 show no light, refuse to produce vapour, flash an error or work only with one particular pod? Recording the behaviour will narrow the fault and give a retailer or support team useful information.

Check that any power control is unlocked and that the indicator is not covered. If the device is draw-activated, a blocked airflow path or absent pod may prevent activation. On button-operated versions, accidental lockout is also possible.

Power-cycle the setup by switching the device off, disconnecting any cable and waiting several minutes. Reconnect the charger, then use the start-up procedure in the TP800 instructions. Avoid random multi-press button combinations that could trigger lockout.

Give the battery a proper charge

Use the charging method specified for the exact TP800 variant. If it takes USB-C, use a clean, undamaged cable and a reputable wall adaptor. Do not substitute a loose, exposed cable or attempt to charge the battery with improvised contacts.

A wall adaptor usually supplies more reliable power than a laptop port, while a fast charger can be unsuitable if the device does not support rapid charging. Check the voltage and current requirements in the product documentation before connecting it to any adaptor.

A completely flat battery may need the full manufacturer-recommended charging period before it shows an indicator. If there is still no response, disconnect the cable after charging and test the device again. Do not leave a suspect battery charging unattended.

Inspect the pod and connection

On removable-pod versions, take the pod out gently and check that it sits squarely when reinserted. Look for dust, oily residue, a displaced sealing ring or a damaged contact. Never use metal to scrape the contacts or force the pod past its locking point.

Check that the pod contains liquid and that its seal is intact. If e-liquid has leaked around the connection, wipe the exterior with a dry cloth and allow the area to dry completely. A loose or damaged pod may trigger protection rather than fire the coil.

If possible, test with a known-good compatible pod. A pod that was previously used, stored in heat or left empty may not activate the heater correctly. Do not keep firing an empty device or continue testing if the pod, connector or unit becomes warm to the touch.

Clean the controls and charging port

With the TP800 switched off and unplugged, remove the pod if the design allows it. Hold the device upside down and gently clear loose lint from the charging port using a dry, soft brush. A cotton swab can also remove visible debris without pushing it deeper inside the housing.

Clean around exposed contacts with a completely dry cotton swab. Do not flood the battery compartment with alcohol, cleaner or e-liquid, as liquid can cause a short circuit or permanent damage. If liquid has entered the device, do not charge or use it.

Check that the firing button moves freely and is not being held down by the case. Keep the mouthpiece and airflow channel clear. A sealed TP800 should not be opened for cleaning; contact the seller if contamination cannot be removed from the exterior safely.

Reset the TP800 safely

A reset must follow the manufacturer’s documented procedure. Start-up, lockout and reset sequences can differ between Lost Mary models, so check the instructions supplied with your exact version rather than assuming a method used on another device.

Some versions reset through a specified button sequence, while others respond to removing the pod and reconnecting the charger. Never push a pin, paperclip or other object into an unidentified hole in the body, as this could damage the battery or activate an unintended function.

Before resetting, rule out a loose pod, low battery and button lockout. Let the device cool if it has been stored or used in a warm environment. If the correct reset does not restore power, repeated attempts are unlikely to revive a damaged battery and should be stopped.

Read battery and safety indicators

Light patterns are model-specific. A solid light may confirm that the device is powered, while repeated flashing can indicate a low battery, absent pod, overheating or another protection mode. Note the colour, number of flashes and timing instead of guessing from the colour alone.

Document what you have tested, including the cable, adaptor and pod used. If the unit remains unresponsive, contact Lost Mary support before opening it. Include purchase details, batch information and clear photographs, but never send an unsafe, hot or swollen device by post.

Stop using the TP800 if its casing is deformed, the battery smells unusual or heat continues after it is switched off. Keep it away from combustible material and contact the seller for safe handling instructions. A counterfeit battery may lack the protections found in a genuine product.

Decide whether it needs replacement

Complete one final test using a known-good compatible pod, a sound charging cable and the documented start-up method. If the TP800 produces no light at all, it is unlikely that a replacement pod alone will solve the problem. If it powers up but never heats, the pod, connection or control system may be faulty.

Check the warranty and keep the receipt or order history. Lost Mary Pro lists flavour, nicotine strength, capacity and price for ranges such as BM600, BM600S, BM6000, Tappo and TP800. Match the exact model because pods and accessories from one range may not fit another.

Do not keep using a TP800 that fires intermittently, works only when held at an angle or behaves differently after charging. Ask a licensed vape shop or local council about accepted battery and vape-waste disposal, and never place a damaged lithium battery in household rubbish.

Additional Troubleshooting and Replacement Options

If the TP800 remains unresponsive after the correct charging, pod and reset checks, arrange warranty support rather than attempting to open the battery compartment. Keep the device away from heat, keep the purchase record, and describe each fault precisely so the replacement process can be handled without further risk.

When replacement is justified, compare the replacement TP800 options available from Lost Mary Pro, then confirm the device type, compatible pods, nicotine strength and Australian compliance information before ordering. Choose a genuine product from a licensed seller, test it with the correct pod and stop using it immediately if the battery or connection behaves abnormally.
