Dehumidifier displays P2 and stops collecting water; bucket may be empty.

Safety: Unplug before inspecting the bucket area.

Steps:

• Empty and reseat bucket: Remove the water bucket, empty it completely, and reinstall it firmly until it is fully engaged.
• Check float position: Inspect the float inside the bucket. It should rest at the bottom when empty. Free any obstructions and clean mineral deposits.
• Inspect continuous drain setup: If using a hose, ensure it slopes downward continuously to a drain and is not kinked. Backed-up water can lift the float prematurely.
• Test bucket switch: With the unit unplugged, press the bucket switch lever by hand. If the unit runs normally when the switch is held (after re-powering), the float may not be actuating it correctly.
• Replace faulty components: Install a new Challenge bucket full micro-switch or bucket float assembly if either is damaged or unreliable.
