Purchased this in January 2018 along with other LG appliances and am very pleased with my purchases. This dish washer run so very quiet. Cleans my dishes/pots/silverware perfectly.

Old dishwasher had to turn the TV up, this one you can be standing by it and wonder if itÕs running, so quiet!

Love the optional control! It's very quiet, has several wash and dry options as well as a self cleaning option. The dishes and pans are spotless, even those that are heavily soiled. The 3 trays and adjustable middle shelve are great ~ no more waiting to put the large pans in the dishwasher. The interior light is a nice touch. . And the exterior design is very sleek. Note: The 10 year Direct Drive warranty sticker which looks like it's permanently attached to the front of the dishwasher was easily remove without scratches to the stainless steel.

Works Great, Looks Great

What I like: Works great and is very quiet. My favorite feature is the adjustable top rack to accommodate tall items. I originally thought that the third thin rack at the top, intended for flatware, would not be useful as I prefer to use the flatware basket. I had planned to remove it, but it turns out to be very useful for long pieces like spatulas, wooden spoons, etc. or other flat items (small plastic lids).What I don't like: Can't tell time left in the cycle without opening the door, and the long running time (an issue with all the new dishwashers not only LG).Overall I am very happy with it.
