Safety first: Remove the battery pack before opening any covers. Do not probe internal electronics while connected to power.

Rule out simple causes: Ensure the dust cup is installed correctly and filters are seated; some models will not run the motor if components are misaligned.
Check for burning smell or discoloration: Smell near the motor vents. If you detect a burnt odor or see melted plastic, do not attempt to run the vacuum again.
Visual inspection (if comfortable): Remove the dust cup and any accessible covers to visually inspect the main PCB area (without disassembling sealed sections). Look for burnt components or loose connectors.
Do not bypass safety circuits: If E6 remains, the motor or control board is likely damaged. Continued use can cause further damage or fire risk.
Service recommendation: Contact a qualified technician or Levoit support for main body replacement or control PCB/motor assembly service.
