Remove top and back panel. Black hose goes from bottom of barrel to pressure switch at top left of washer (looking at back of washer). Remove and replace hose and clip. Make sure hose is clipped into clip coming off of discharge hose at the top left side of machine and then press clip on hose into back of washer barrel. Replace back and top panel. This hose gets loose from its clips and ends up rubbing against the spinning part of the barrel rubbing a hole in the hose. This causes the washer to not know what the water level is and either shows an error or keeps filling the barrel causing leaking.
