REMOVE PLUG BEFORE YOU START. After being told to remove lower cover and unscrew cap, drained water out carefully, but found the cap did not come out as told, found this answer, tilted machine back, unscrewed completed fitting from machine, used pliers to open grippers to remove the 3 pipes, also took off motor at rear (special screws), found 2 - 1p's and part of my wife's best top! flushed with water & refitted, I hope that fixed it!!
