Possible Causes

Fully discharged or failed battery pack, Faulty TCL charger or dock, Broken battery latch preventing contact, Blown fuse or failed power stage on main PCB

How to Fix / Troubleshooting

Safety first: Inspect only external parts; do not open the battery or main body casing.

  • 1. Charge fully: Place the vacuum on the TCL charger for at least 3–4 hours. Confirm charger LED is on.
  • 2. Try another outlet: Use a different wall outlet to rule out power issues.
  • 3. Check battery seating: Remove and reinstall the battery pack, ensuring it clicks firmly into place.
  • 4. Look for life signs: Press the power button while on the charger. If no LEDs or sounds occur, suspect charger, battery, or main PCB.
  • 5. Substitute components (if possible): If you have access to another TCL charger or battery of the same series, test with those to isolate the faulty component.

If still dead: The main control PCB or internal fuse may have failed. Professional diagnosis and replacement of the PCB or internal wiring is required.
