DIAGNOSIS Yes, it's designed to evaporate most condensation out the exhaust. Constant dripping means it's producing more water than it can evaporate, which happens in two main scenarios: you're running it in a very humid room (like a basement), or you're running it on Dry (dehumidify) mode, which intentionally collects more water.
FIX First, check your mode. Switch from Dry mode to Cool mode if you want less water collection. If you're already on Cool, you need to route the water. 1) Ensure the unit is perfectly level so water flows to the internal pump. 2) Get the optional drain hose (often sold separately). Remove the rubber manual drain plug on the back/bottom and screw the drain hose in its place. Run the hose to a floor drain, sink, or bucket. The unit will now pump out water continuously instead of trying to evaporate it all.
IF THAT DIDN'T WORK If water is leaking from somewhere other than the drain port, the internal condensate drain pan or hose might be cracked or disconnected. That requires opening the cabinet, which is a more involved repair best done by a technician if the unit is under warranty.
HEADS UP Never let the unit pump water upward more than about 3 feet—the small pump can't handle major lift. Keep the drain hose path as flat and downhill as possible for reliable drainage.
