Humidifier shows F2 and shuts off mist output

Safety: Unplug the humidifier before handling the water tank.

Steps:

• Remove and inspect tank: Take out the water tank and inspect the float assembly (if visible). Ensure it moves freely up and down.
• Clean float and chamber: Rinse the float chamber with warm water and mild vinegar to remove mineral deposits. Do not use harsh chemicals.
• Check tank seating: Reinstall the tank, ensuring it is fully seated and properly aligned so that the float magnet can actuate the reed switch in the base.
• Test switch (advanced): With the unit unplugged, access the base and locate the reed switch or water level sensor. Test continuity while moving a magnet near it. Replace if it does not change state.
• Replace faulty parts: If cleaning and reseating do not clear F2, replace the float assembly or water level switch as a unit.
