Dehumidifier shows bucket full indicator even when the bucket is empty and properly installed.

Safety first: Unplug the unit.

• Re-seat bucket: Remove and firmly reinstall the bucket, ensuring it is fully inserted and level.
• Inspect float: Look inside the bucket cavity for the float mechanism. Ensure it moves freely and is not jammed by dirt or scale.
• Clean float and cavity: Wipe away any buildup that could cause sticking. Rinse the bucket thoroughly.
• Switch test: If accessible, manually actuate the bucket switch with a non-metallic tool while the unit is powered (exercise caution and avoid live contacts). If the indicator changes, the switch is working and the float alignment needs adjustment.
• Replace switch or float: If the switch does not respond or the float is broken, replace the faulty component.
