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

Safety first: Unplug the unit before working in the bucket compartment.

• Remove and reseat bucket: Take out the bucket and reinstall it firmly, ensuring it is fully inserted.
• Inspect float mechanism: Look for a plastic float or lever that moves when the bucket fills. Ensure it moves freely and is not jammed by dirt or scale.
• Clean float and switch area: Wipe away any buildup that could prevent proper movement.
• Test switch manually: With the unit unplugged and bucket removed, gently press the bucket switch lever. You should hear a click. If not, the switch may be defective.
• Replace switch: If the switch does not click or tests open/closed incorrectly with a multimeter, replace the bucket full switch assembly.
