You’ve probably using conditioner and short washes.
It attracts black goop to stick to the inside of the washer. The best way to get rid of it is have someone strip it and power wash it.
Stop using conditioner (softer) right now and never use it again. Buy powder for your machine and avoid using the little tablets.
