Re:16 yr old Whirlpool Top Loading Washer. After washing, there are clumps of dirt deposited near the top of the tub: Thin, dark brown, with hairs. New supply hoses didn\\\'t help. Raised drain hose out of tub, no help. Checked water coming in,no problem.Sometimes, after filling, water in tub seems slightly brown, but I believe it may be from clumps getting stuck under agitator and dissolving in water. Would this be a clogged \\\"magic clean\\\" automatic lint filter, that is backing up into the tub when draining?
