Our LG WM2010CW front load washer has been leaking in the front for approximately 1 year on about every 4th-6th wash. My husband can fix just about anything but, this we could not diagnose. WE FINALLY found the issue. Hope this helps someone else having the same issue.
Problem: Pictures attached. At sometime when adding liquid bleach to the detergent dispenser, the small circular plastic gasket from the bleach bottle cap dropped into the dispenser. Eventually the plastic gasket ended up in the connector hose between the dispenser and the tub. Depending how the plastic piece moved during the wash cycle occasionally it would block the flow of water, causing it to leak out the front.
