Humidifier water level in base does not drop even though mist is produced

Safety: Unplug before handling the tank.

Steps:

• Check tank vent: Inspect the small air vent hole in the tank cap. Clean any blockage with a toothpick or pin.
• Test valve movement: Press the spring-loaded valve in the cap to ensure it moves freely and opens fully.
• Refill and reinstall: Fill the tank, tighten the cap, and reinstall. Watch for air bubbles rising into the base, indicating water flow.
• Re-seat tank: If no bubbles appear, remove and reseat the tank to ensure proper alignment.
• Replace cap assembly: If the valve or vent is damaged, replace the tank cap assembly.
