You must locate and eliminate the source of the dirt.
Is the dirt in the water supply?
• Hand fill the washer with clean water. If the dirt is not present after the wash, you must ensure clean wash water.
Is the dirt in the washer?
• Check the filters of the washing machine. If the filters are dirty, clean or replace them.
Is the dirt in the air?
• Check the cloth before and after you hang the cloth out to dry. If the cloth is clean when wet, the place where you dry your wash must be clean.
Work step-by-step to isolate when the problem occurs. After you locate the source of the problem, take corrective action. This might be to change the water supply, the treatment of the water supply, change or clean the washer water filtration system, change the method or location for drying, wash the cloth by hand, accept the dirt as unavoidable, discard or replace the cleaning cloth, use disposable materials.
