Safety: Unplug the humidifier before cleaning.

Check water level and seating: Ensure the tank is full enough and properly seated so water flows to the base.
Descale transducer: Clean the ultrasonic disc with a vinegar-water solution and a soft cloth, removing mineral deposits.
Clean mist outlet: Inspect and clean the mist outlet and any directional nozzles with a cotton swab.
Driver circuit: If mist remains weak, the ultrasonic driver PCB may be failing and should be replaced.
