Humidifier fan runs but water level in base does not drop; wick remains mostly dry.

Safety first: Unplug the unit and remove the tank and wick.

• Verify correct wick: Confirm you are using the correct Essick Air wick model number for your humidifier.
• Install properly: Ensure the wick is fully seated in its frame and the bottom edge is submerged in the water channel when installed.
• Replace old wick: If the wick is older or has visible scale, replace it. Old wicks can lose their ability to absorb water.
• Check water level: Make sure the base fills to the proper level when the tank is installed.
