          [This review was collected as part of a promotion.] Worst appliance I have ever owned!! It does not clean my dishes what so ever!! They were so focused on saving water that it doesn't clean anything off my dishes and it takes 3 hours!!

            Great, but...
            [This review was collected as part of a promotion.] Great dishwasher. Does a great job. However, after 5 years the middle rack is rusted everywhere. Rust places are NOT where dishes or anything rubs. Saw similar reviews.

            Bad racks/quality, pretty good wash
            This dishwasher seems to wash well, but the racks have completely rusted out. I will not be buying another LG if this is the quality.

              This is one the worst appliances that I've ever purchased!!! This dishwasher began to break within the first yr piece by piece it has fallen apart. I have a household of 2. My husband and I may run it 2 to 3 times a week. We're 64/70. I'm the only one who loads and unload the dishwasher. It washes dishes horribly. I am in the market in less than 3 yrs for a new dishwasher....you've been warned ⚠️ ⚠️ ⚠️

              Top Rack already rusting only 4 years
              Dishwasher is only 4 years old, and the top rack is rusting out. I love the dishwasher but never LG again. My previous brands have never rusted just replaced because the dishwasher quit. I wanted to try LG as I have Refrigerator and washing machine and love them.

                  Has good features, but some design flaws
                  I have owned the dishwasher since 2018, and I like the 3 rows and the moveable middle row. However, almost immediately the middle row (for cups & bowls etc.) began to have portions start to rust. Also, when the dishwasher came to us there was a almost unnoticeable hairline crack on the touchpad-control panel where it "power button" is. Since then, the crack has grown to the point that I can't power the dishwasher on by touching it. I was sent a new control panel, but it has the same crack in the same place. When installing the new control panel/touch pad, it powers on, but none of the buttons on the right side work, including the start button. If I could go back, I would get a dishwasher with actual buttons instead of these simulated ones.

                    Cracked Control Panel
                    Hi, Hi, I saw another review regarding the cracked control panel for the dishwasher below. I have the same issue. I was really disappointed to have this issue after enjoying the machine for a while. I never expected this issue from the major company. Please let me know how and what I can do for this matter. I hope to get your prompt response.
