The front door seal is referred to as the "bellow". They will wear out with age and may become mishapened from repeated pressure from the door being closed. Over time the bellow can stretch or develop rips and tears and begin to leak. If the bellow is leaking, or no longer providing a good seal, it must be replaced. This will cause water to puddle under the front of the washer and inside the cabinet.

NOTE: If you leave the door OPEN between washes this will help prevent constant pressure on the door seal which can stretch it out of shape over time. It is also beneficial to allow the wash tub to air out to prevent mold and mildew from forming.
In addition, overloading the washer can contribute to premature wear and tear on the bellow which can lead to rips, tears and possible dislodging from the bellow clamp seals. Always follow the manufacturer's recommendations for loading in your owner's manual.
