Dehumidifier shows P2; unit may run but not drain properly.

Safety: Turn off and unplug the unit before handling hoses.

• Verify hose connection: Ensure the drain hose is firmly attached to the Klarstein drain outlet and that any rubber plug has been removed.
• Clear outlet: Inspect the rear drain spout for mold, scale, or debris. Clean with a small brush and warm water.
• Check hose routing: Make sure the hose runs downhill with no sharp bends. Shorten the hose if it is excessively long or coiled.
• Inspect for freezing: In cold environments, ensure the hose is not frozen. Thaw and insulate if necessary.
