Diagnosis
A leak from the bottom front, with the supply hoses and drain hose confirmed dry, typically comes from three places: the internal water inlet valve connections, the tub seal (where the outer tub meets the transmission), or a crack in the outer plastic tub itself.
How to Fix It
First, rule out the easy stuff. Run a cycle and watch closely. If it leaks only during fill, it's likely the inlet valve on the back of the control panel. If it leaks only during agitation/spin, it's likely the tub seal or a tub crack. Check the drain pump filter area (the small service door) first—that cap might not be tight or its O-ring might be damaged, causing a slow drip that runs forward.
If That Didn't Work
A cracked outer tub is a known, though less common, issue with some LG top-loaders. You'd need to partially disassemble the washer to confirm. The tub seal failure is more common with age and leads to water leaking past the agitator shaft.
Heads Up
Don't ignore a small leak. Water inside the cabinet can eventually reach the main control board (mounted at the bottom on some versions) and cause a very expensive short-circuit failure.
