Possible Causes

Cracked water tank, Damaged or missing tank cap gasket, Misaligned tank valve, Overfilling or tilting the unit, Cracked base reservoir or seal around transducer module

How to Fix / Troubleshooting

Safety: Unplug the unit immediately if water is leaking near electrical parts. Dry the area before further inspection.

Steps:

  • Remove and inspect the tank: Look for visible cracks, especially around the handle and bottom. Fill the tank over a sink and check for drips.
  • Check tank cap and gasket: Inspect the rubber gasket on the cap for deformation, cracks, or missing sections. Replace the tank cap gasket if damaged.
  • Inspect tank valve: Ensure the spring-loaded valve closes properly when the tank is removed and opens when installed. Clean any debris.
  • Check base reservoir: With the tank removed and base dried, pour a small amount of water into the base and watch for leaks around the transducer module or seams. If water seeps out, the base or seal is compromised.
  • Replace damaged parts: Replace the water tank if cracked, or the transducer module seal / base reservoir if the leak originates there.
  • Level placement: Ensure the humidifier is placed on a flat, level surface and not overfilled beyond the indicated maximum.
