A front-load washer seals the door with a rubber boot. Water that runs out the door almost always comes from a torn or deformed boot, trapped lint or hair that keeps the seal from closing, or an overloaded drum that pushes water past the edge. Wipe the boot fold clean after every use and leave the door slightly open between loads so it dries.
In Minnesota, hard water can leave mineral deposits in the boot fold, and those can keep it from sealing. A cleaning cycle with washer cleaner once in a while and a wipe of the fold usually fixes a weeping door. If the boot has a hole or is cracked where it clamps to the tub, it needs replacing.
