Dehumidifier shows P2 and stops running, often after some time of operation

Safety first: Turn the unit OFF and unplug it before draining water.

Steps to resolve P2:

• Drain the reservoir: If your Whynter model has an internal tank or tray, remove the drain plug or pull out the tank and drain all water into a suitable container.
• Check continuous drain setup: If you use a gravity drain hose, disconnect it and blow through it or flush it with water to clear any blockage. Ensure the hose runs downhill with no kinks or loops.
• Clean the drain port: Inspect the rear or side drain outlet on the unit. Use a cotton swab or small brush to remove lint, slime, or mineral buildup.
• Reinstall and test: Reconnect the hose securely, making sure the connection is tight and leak-free. Plug the unit back in and run it. Confirm that water flows freely out of the hose.
• Sensor check: If P2 appears immediately after draining and cleaning, the internal water level sensor or float may be stuck or defective and may need replacement.

Note: Always route the drain hose to a floor drain or suitable container lower than the unit to maintain proper gravity drainage.
