Diagnosis
Water under the front usually comes from the door boot seal, the drain pump filter housing, or the inlet valve connections.
How to Fix It
Check the drain pump filter first. It's behind the small kickplate panel. Ensure the filter cap is screwed on tightly and the rubber gasket is seated properly. Overtightening can also damage the gasket.
If That Didn't Work
Inspect the rubber door bellows (gasket). Look for tears, especially in the lower fold. Also, check where the bellows clips to the front tub ring. Debris can get caught there and break the seal.
Heads Up
Do not ignore a leak from the inlet valve area at the back. A slow leak there runs down internal hoses and pools at the front, mimicking a front leak. Pull the machine out and check the wall-side connections and the valve itself.
