By the name of "self-clean filter'. It already answer your the question. 1st understand how is the self-clean filter work. It filters out lint (毛毛和线头) that comes off from cloths. Overtime lots of lint are collected. Then the filter needs to be cleaned. Or the lint will not filtered out, all the lint will just circle around with the cloths (This is the reason why you see lint on the cloth after washed), Sears told you run the wash machine free with water an bleach, The suggestion is try to remove or loosen up all accumulated lint from the filter. And it was better after. Right? So do it few more time or manually clean the filter remove all lint by hand.
