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

Safety: Turn off and unplug the unit.

Steps to clear false bucket full:

• Inspect bucket float: Ensure the float moves freely and is not jammed by mineral deposits. Clean and free it.
• Reinstall bucket: Slide the bucket in firmly until it clicks or seats fully. Make sure it is not tilted.
• Check bucket switch: Locate the bucket full switch near the bucket cavity. Manually press the switch lever and see if the indicator changes (with power restored briefly).
• Replace switch or bucket: If the switch does not respond, replace the switch. If the bucket is warped and not engaging the switch, replace the water bucket.
