                      Defects not warrantied
                      Less than 1yr in this dishwasher started cracking on the electronics display. LG would not warranty it even though it was clearly a manufacturer defect. They did offer us to pay to have someone come out and take a look at it and great with recommending local repair facilities. Not satisfied, won’t buy LG appliances again.

                        It has a lot of features
                        I have owned this since 12/1/19 and the motor went up shortly after buying it. Just ordered new racks because the original ones are rusting. Had a code last week and had to have another motor for the sprayers replaced.

                          Love our new dishwasher
                          [This review was collected as part of a promotion.] Very happy with our new dishwasher. Cleans beautifully, love the night time option resulting in more complete drying. The options for dish arrangement is excellent. The option panel is comprehensive but easy to set up. Overall very pleased with this purchase.
                            High Quality Product & Great Idea in Theory
                            [This review was collected as part of a promotion.] This product is great start for Industry 4.0; however it seems like its not ready yet. At the very first day techs warned us about Wireless capabilities and App features which usually does not work. Eventually I have never connected with the app. True steam technology provides remarkable results however I wouldnt count on 3rd (cutlery) Rack; it does not clean at all times. We are happy about how silent it is but wash cycle takes 3 and half hours. Unfortunately currently we are having issues with our lovely dishwasher; it trips 15A circuit breaker; maybe because of heat it creates. Geeksquad will come next week. Long story short; great product, great improvement comparing to previous one however it doesnt seem quite ready for me. I would wait another year or go for Signature version of it.

                              Excellent dishwasher.
                              [This review was collected as part of a promotion.] I totally love this dishwasher. It works great and it’s very quiet. The outside door handle is different on the studio model so it doesn’t match my other appliances from LG. I will probably sell this one and get another LG to match my other appliances. This one is well worth the price.

                                    Quiet, powerful, and looks classy
                                    This is my first new dishwasher in years, and it does what I need it to do: wash dishes! 1. It's quiet - I can barely hear it run, 2. Powerful - it cleans dirty dishes even without pre-washing, 3. It looks great! The wifi feature is really only good for monitoring, as I can't change settings mid-cycle. I purchased mine in black stainless.

                                      LOVE this dishwasher!
                                      I generally do a LOT of research before committing to an appliance and a brand. We already own three other LG appliances, and we have been thrilled with their quality and clever innovations. As to this dishwasher, the features sold me! The True Steam is amazing. It loosens up the food on dirty dishes and leaves them spot-free. Our dishes have never been cleaner! Another feature I like is how quiet it is. I actually had to put my head down by the machine to hear it running. I love the adjustable features on each rack. On the lower rack, you can raise and lower all of the dish brackets to fit casserole dishes, platters, pots and pans, large bowls, and pitchers, as well as regular plates and bowls. The middle rack also has adjustable brackets. In addition, the entire middle rack cleverly raises and lowers to accommodate tall things. The third rack is really helpful for spatulas, mixing spoons, measuring cups/spoons, knives, and more - all the things we used to cram into the second rack. Also, one side of the rack can lower for taller utensils. Another feature we have yet to try, with our family of 6, is the half load option. You may select this option to clean only what’s in the top or bottom half of your dishwasher, perfect for small loads. The only negative we’ve found is longer cycles, but we knew this before purchasing. I read reviews that the cycles on this dishwasher are much longer than old dishwashers. It’s true, most cycles are 2-3 times as long as a 1990s dishwasher. However, even with the longer cycle times this model uses a lot less water and energy per load than our old dishwasher, and it holds more dishes. Plus, if you want a quicker cycle you have the option to run a “Turbo” cycle which will clean faster (just with more noise, water, and energy). I usually run our dishwasher at night, so it doesn’t matter how long it takes. Overall, I think this is a great dishwasher and I gladly recommend it!

                                        Leaks from soap dispenser
                                        First the dishwasher cleans well and is quiet. I really have 0 issues with its performance and the wifi is handy and easy to setup. When I first received the dishwasher I installed it and ran a test cycle and everything was great. Then on the 2nd cycle, I noticed there was a puddle after inspecting my connecting I realized it was coming from inside the door. I exchanged that one for a new model and you will never guess where it leaked! From the door... To satisfy my curiosity I pulled the door panel to verify and Ill add the photo below. Clearly this wasn't a one-off I had 2 units with this issue.
