Humidifier leaks water from the base or around the tank.

Safety first: Unplug the humidifier and remove it from any electrical devices or surfaces that can be damaged by water.

Steps to stop leaks:

• Inspect tank: Remove the tank and check for visible cracks or damage. Replace the water tank if cracked.
• Check cap and gasket: Examine the tank cap and rubber gasket for wear, deformation, or debris. Clean and reseat, or replace the gasket if it no longer seals.
• Avoid overfilling: Fill only to the indicated maximum line.
• Seat tank properly: Ensure the tank is placed squarely on the base so the valve opens correctly and seals against the base gasket.

Warning: Do not use sealants or glues on drinking-water-contact surfaces; always replace defective parts.
