Diagnosis
Water pooling under the unit usually means internal condensation is dripping where it shouldn't. This is often due to a blocked drain path inside or a misaligned drain pan.
How to Fix It
Unplug the unit and get ready to look inside. 1) Remove the bucket. 2) Inspect the area where the bucket sits. You'll see a channel that leads to the drain port at the back. Clear any visible debris, dust bunnies, or even small insects from this channel. 3) Check the rubber drain plug at the back. If it's not seated perfectly, water can drip back along the casing. Remove it and reseat it firmly. 4) Tilt the unit gently side-to-side over a towel. If you hear water sloshing inside, there's a clog further in the internal drain pan.
If That Didn't Work
The leak might be from a cracked internal drain pan or a disconnected hose inside the cabinet. This requires disassembly. Remove the rear cover (see the "dead control panel" fix for steps) and look for the white plastic internal condensate pan. Check for cracks and make sure the short hose that connects it to the rear port is attached securely.
Heads Up
This leak is different from an overflowing bucket. If the bucket itself is full and the unit hasn't shut off, that's a faulty float switch. This leak is mechanical. Be thorough drying everything inside before plugging it back in after your inspection.
