E9 error; unit may stop and beep; sometimes associated with water leakage or full tank

Safety: Unplug the portable air conditioner before draining water to avoid electric shock.

• Empty the tank: Move the Olimpia Splendid portable unit to a location where water spillage is acceptable. Remove the lower drain plug or cap and drain water into a shallow tray or container.
• Check float switch: Locate the internal float or water level sensor near the condensate collection tray. Ensure it moves freely and is not stuck by dirt or algae.
• Clean the tray: Wipe the condensate tray with a cloth and mild detergent to remove slime or debris that can jam the float.
• Inspect drain hose: If using continuous drain, check that the hose is not kinked, elevated above the outlet, or blocked. Flush it with water if necessary.
• Reset and test: After draining and cleaning, reinstall plugs securely, reconnect power, and run the unit. E9 should clear.
• Replace sensor if needed: If the tank is empty but E9 persists, the float switch or water level sensor may be faulty. Replace it with the correct part for your Olimpia Splendid model.
