Ok, great, that's what I suggested before. This is not a splutch problem. The splutch (splined clutch) is the part above the pulley attached to the gearcase. The pulley is known as a splutch pulley, but it is not the splutch. This loose nut is a known problem by Whirlpool. They put out a service notice advising that the nut and pulley be replaced and threadlock added before replacing the nut. It is generally not neccessary to replace the pulley or the nut. Just put some blue 242 loctite on the input shaft threads and retighten the nut. I assume after unplugging the washer for 3 minutes that he plugs it back in to unlock the lid lock. The lid lock will not unlock on it's own. It requires power to unlock it as well as to lock it. It has a latching mechanism that maintains position (locked/unlocked). Only a brief pulse of power is used to lock/unlock it. Once locked or unlocked, it stays that way until another pulse of power is applied.
