Crane humidifier base fills with water and overflows internally, sometimes causing gurgling sounds.

Safety first: Unplug the unit and carefully remove the tank to avoid spilling more water. Dry the base with towels.

• 1. Inspect tank valve:
  • Look at the spring-loaded valve on the bottom of the tank.
  • Check the rubber seal for cracks or deformation.
• 2. Clean valve area:
  • Rinse away any debris or mineral buildup around the valve.
• 3. Check tank neck fit:
  • Ensure the tank sits correctly on the base and the valve aligns with the base inlet.
• 4. Test over a sink:
  • Fill the tank, install the cap, and press the valve pin over a sink to confirm it opens and closes smoothly.
• 5. Replace tank or valve assembly:
  • If the valve does not seal properly, replace the tank or valve assembly as supplied by Crane.
