Dehumidifier bucket full light stays on even when the bucket is empty and properly installed.

Safety: Unplug before working inside the bucket compartment.

Steps:

• Re-seat bucket: Remove and reinstall the bucket firmly, ensuring it is fully inserted and level.
• Check float movement: Locate the internal bucket float and ensure it moves freely. Clean any debris or scale that may cause sticking.
• Inspect switch: The bucket full switch is usually a small microswitch actuated by the float or bucket edge. Verify the actuator moves when the bucket is inserted.
• Switch replacement: If the switch does not click or change state when actuated, replace the bucket full switch.
• Bucket replacement: If the bucket is warped and does not properly contact the switch, replace the water collection bucket.
