Hi. Welcome to Just Answer.
It seems that this is a common complaint with this model. Customers either love it or totally hate it.
Unfortunately it seems that LG has not figured out what is going on or just dont want to. The wash plates in these units are hard on clothes as rather than tumble them or move them around the wash drum with a regular agitator they have more of a grinding effect.
If the unit is less than a year old you should be able to get a different model after enough service calls under the warranty. Do not let them put it off as customer overloading. Get the service person out there and show them what is going on. If you dont get satisfaction call and have another tech come out. Just keep it up and eventually they will get tired of coming out and do something about it.
I know that this isnt what yuou want to do, but there really isnt much else that can be done. It is just a bad design, and LG is eventually going to have to bite the bullett and do something. The same thing happened a few years back with the Whirlpool Neptune units. It took a class action law suit to get them to do something about the problem. Hopefully that wont be the case here.
