Possible Causes

Cracked water tank, Worn or mis-seated tank cap gasket, Overfilling tank beyond max line, Hairline cracks in base reservoir

How to Fix / Troubleshooting

Safety: Unplug the humidifier before handling water spills.

Steps:

  • Inspect tank: Remove the tank, dry it, and inspect for cracks, especially around the bottom and handle.
  • Check cap and gasket: Remove the tank cap and examine the rubber gasket or O-ring. Clean it and ensure it sits flat. Replace if cracked or hardened.
  • Fill correctly: Refill only to the indicated max line. Overfilling can cause leaks.
  • Inspect base: Check the base reservoir for cracks or warped plastic. Replace the base assembly if damaged.

Tip: Do not carry the humidifier by the tank alone when full; support the base to avoid stress cracks.
