After some simple research I diagnosed the problem being the rotor and upon visual inspection it was confirmed. I used appliancepartspro.com before so I ordered the part during xmas rush and to my surprise it was delivered in a day and a half. Rotor replacement is very simple and takes less than 15 min. Runs like a champ now. Also called lg because the direct drive system was under warranty for 10 yr they said they would fix my problem $280 everything included. I fixed it for less than $75.
