Friends gave us a washer and dryer from their grand mothers condo, she was the only one to ever use them. They are GE and look BRAND NEW. The dryer runs great. The motor on the washers seems to vibrate. When I hold my finger on the top of agitator it speeds up. Can any one tell me how old this from # below? Any ideas on what might be wrong? Like I said, they look show room new! Thanks! S # FZ129988G M # WWA 7070 GAL WH Do these machines have a history of longevity?
