Customer Questions and Answers for Bearing, Front by Whirlpool

Robert, A "Duet" washer, Yes an damaged tub bearing could be the cause of the spots on your articles, But the repair would require replacement of the rear tub assembly W10772618. A lot of "stains" on articles are caused by a build up of softner, detergent, dirt and body oils, that accumulate in the tub or hoses, You may want to attempt to clean the tubs usuing a product like "affresh" or a combination of bleach and powder automatic dishwasher detergent, and a long hot wash cycle(you may have to repeat the process a couple of times).
