Humidifier displays F6 and stops, often accompanied by unusual noise from the fan or pump (if equipped).

Safety: Immediately unplug the unit. Do not continue to reset and run it, as this may cause further damage or fire risk.

• Check for liquid ingress: Inspect around the base and control panel for signs of water spills or condensation entering the electronics. If present, allow the unit to dry for at least 24–48 hours in a warm, dry place before retrying.
• Smell for burning: If you detect a burnt smell or see scorch marks through vents, do not reuse the unit until inspected by a professional.
• Try a different outlet: Plug into a properly grounded outlet with no extension cords to rule out supply issues.
• If F6 reappears: An internal component (fan, atomizer, or PCB) is likely shorted. This requires component-level diagnosis and replacement by a service technician.
