Dehumidifier shows P2 and stops; often associated with continuous drain or pump mode.

Safety: Unplug the unit. Be prepared for water spillage when disconnecting hoses.

Steps:

• Check continuous drain: If using a hose, disconnect it and ensure it is not kinked or clogged. Flush it with water.
• Drain adapter: Verify the drain adapter on the back of the unit is fully inserted and sealed.
• Internal drain channel: Remove the bucket and inspect the drain outlet from the evaporator tray. Use a small brush or pipe cleaner to clear slime or debris.
• Pump overflow: On pump models, open the pump tray and ensure the overflow float is not stuck in the up position. Clean as needed.
• Test operation: Reassemble and run the unit with a short, downward-sloping drain hose or just into the bucket to confirm P2 clears.
