Right off the bat we had a problem with the 3rd rack not sliding in and out smoothly.   Had to deal with online repair request and finally able to get a repairman to fix the problem.  Sprayer apparatus on top of machine had fallen down slightly and was blocking the ability of the rack to slide in and out smoothly.   Now we've noticed that there is a "motor " or something still running in the door hours after a wash cycle has run.  Need to call LG again and find out what this issue is.
