I can see how it would upset you when your washer is ruining your clothes instead of cleaning them. I was able to find a link that includes great troubleshooting advice for this issue. I attached the links below. I hope this helps.
I can understand how important it is to have your washer working correctly. Something like this is usually caused by overloading the washer; clothes will get trapped under the fins of the agitator causing tears. First thing to do is with a pair of stockings over your hand rub the basket down for any burrs that might snag something. Next with a flashlight check all the drum baffles. If one is cracked or loose then something might snag and tear. Check the door bellows. Pull back and check the crevices for anything odd. You seem sure the damage is done in the washer. I would also recommend check the dryer as well. The front load washers by design can't normally damage clothes unless they are overloaded or there is something sharp in the tub. Check these things and reply with any additional details for further assistance. Thank you for using Manage My Life.
