          Seamless new addition
          [This review was collected as part of a promotion.] Bought the unit in December 2021 and installed in January 2022. The wait was worth it. I like the features it has , 3 adjustable racks for dishes and utensils, steam, and turbo washes. It's quiet while in use and the design matches the rest of my kitchen.

            Very quiet dishwasher with interior tub LED lights
            [This review was collected as part of a promotion.] I purchased this LG Signature dishwasher in early January 2021 from Costco that replaced an 8-year old GE dishwasher. Delivery was relatively quick by the 3rd week in January. It's very quiet and I love the interior tub LED lights that are very bright that light up the inside of the dishwasher so I can easily see the dishes that are placed in there. All the previous dishwashers I had didn't have any interior lights, so these lights really help me a lot. It has Wi-Fi connectivity that I linked to the LG ThinQ app on my cellphone that shows the settings and status, such as how many minutes are remaining on the wash, estimated time when it will be completed, which is helpful so I don't need to come downstairs to check if the dishwasher is done washing. As for the installation of this new dishwasher, Costco arranged with a company named Kepco to do the installation after the delivery. When the installer came 3 weeks after the delivery in early February 2021, he removed my old GE dishwasher, installed the new LG, and hauled away the old unit. He did a good job on the installation which took him around an hour and half to complete. I used the new dishwasher for the first time last night and all my dishes were sparkling clean, cleaner than with my old GE dishwasher. Hopefully I will have many years of trouble-free use out of this LG dishwasher.

              Cleans and dries great
              I had to replace an old Bosch dishwasher and chose this one because of the reviews and the noise level. I'm impressed with the features, the blast of steam really works on a tough mess and the night dry function works very well!
                Best Dishwasher I have ever had
                This is the best dishwasher I have ever had. It washes everything crystal clean. You need to use a rinse agent however. My daughter-in-law was skeptical about a crusty macaroni and cheese dish that I put in but it came out clean and bright. The wash cycle is longer than I am used to but not a big issue.
                  Overall...a great addition to our home
                  [This review was collected as part of a promotion.] The dishwasher works really well! My review is at the end of one year ownership. We had an issue where the dishwasher would not drain (about 3 weeks before the manufacturer warranty expired) and the LG Signature team came through. The service side of LG ownership is legit...parts are sent to your home prior to the appointment and the service technician was professional, quick and couldn't tell he was there after he was done. Overall, I think I'm an LG customer for life.
                    Great when it works
                    [This review was collected as part of a promotion.] Wash motor gave out after 1.5 year. Bought the unit almost day 1 after it was released. Disappointed that we had to call support and have someone come out twice to fix it. For being a Signature product, I would hope for signature reliability.
                      Great Washer
                      [This review was collected as part of a promotion.] I got this a month ago and so far it is working great cleaning.
                        Who'd have thought? - Happy my dishwasher died!
                        [This review was collected as part of a promotion.] When the repairman declared my top-of-the-line, seriously quiet, dishwasher as terminal, I had to find something new because there was a 7-month wait to get the brand I had. After research, I settled on the LG Signature. So glad I did. Not only is it just as quiet, but it also washes so much better. Baked on casseroles that once required follow-up hand scrubbing now come out spotless. The capacity is amazing. I'm not sure what more I could have hoped for.

                          Astoundingly poor performance!
                          Wow! Who would think that a dishwasher that costs SO much would do such a terrible job? My dishes are uniformly greasy at the end of a cycle, and to top it off, there are horrible spots on the glasses. This is hands-down the worst dishwasher I have ever owned. SO DISAPPOINTED.

                            Excellent dishwasher!
                            [This review was collected as part of a promotion.] I bought this and received it a few weeks ago. It’s a wonderful dishwasher with great features. The only problem I have is getting the touch sensor to accept start. For some reason it takes quite a few tries to get it to start.
