Beurer humidifier displays 'Lo' and does not start misting.

Safety: Unplug the unit before lifting the tank.

Steps:

• Refill and reseat tank: Fill the tank to the maximum line with clean, preferably demineralized water. Ensure the cap is tightened and the tank is correctly positioned on the base.
• Check float movement: Look for the float in the base or tank. Gently move it up and down with a non-metallic tool to ensure it is not stuck.
• Descale float area: If there is visible limescale, soak the float and its chamber in a vinegar-water solution, rinse, and reassemble.
• Test operation: Plug the unit back in and check if 'Lo' clears. If not, the level sensor or reed switch may be defective and require replacement.
