Portable or window-type Sharp AC: unit stops and P2 is displayed; water tank icon may flash.

Safety first: Unplug the unit before draining water or moving it.

• Empty the tank: Remove the condensate tank or open the drain plug as per the user manual. Drain water into a suitable container.
• Check float switch: Ensure the float moves freely and is not stuck by dirt or scale. Clean gently if needed.
• Inspect drain hose: If a continuous drain hose is used, ensure it is not kinked or blocked and that it slopes downward.
• Level the unit: Use a spirit level to ensure the unit is roughly level so water flows correctly to the tank or drain.
• Sensor replacement: If P2 persists with an empty tank and free float, the water level sensor or float switch may be faulty and should be replaced.
