Water tank fills very quickly or overflows; humidity seems normal.

Safety first: Unplug before inspecting for water damage.

• Check mode: Ensure the unit is not set to continuous mode if you want it to cycle off.
• Verify humidity: Use a separate hygrometer to confirm actual humidity. If normal but the unit runs nonstop, suspect a sensor issue.
• Inspect room: Look for water leaks, unvented dryers, or open windows that introduce moisture. Correct these issues.
• Install continuous drain: If high humidity is expected (basements, laundry rooms), connect a drain hose to avoid tank overflow.
• Replace humidity sensor: If readings are inaccurate and cause over‑dehumidification, replace the sensor module.
