    1st new dishwasher purchase in 22 years, so a lot of the following may be a reflection of the change in design technology and not necessarily a pro/con of this LG product. First, aestheticaly, this is a well designed product. Controls are touch panel (no knobs/buttons/dials) and are located on the door's top edge so you can't see them with the door closed. With nothing on the front face, except the streamlined LG handle which is somewhat elegant in appearance and matches our other appliances, it blends in nicely into our kitchen and is unassuming. For a dishwasher, that's the way it should be. Functionally. Wow, all the options. In an era of being "green" and eco-concious, there is every option available to save energy, reduce water usage, maximize cleaning for specific load types, etc. Unfortunately for me, it's way too much thinking trying to match up all the best options on a daily basis to the contents of my "load of the day" to get the best wash to satisfy me and the future of the earth. So, with all those options available, I use the AUTO cycle almost exclusively -- it's just easier. Similarly, in an effort to conserve electricity, the DW powers down when its done with its most recent load and you have to hit the power button to turn it back on every time. Another related quirk is that every time you open the door during a cycle you have to hit the restart button if you don't shut the door within 4 secs of opening it (and that's almost impossible -- since you typically only open the door during a cycle just to add something you missed after starting it, & you simply can't get an item into the DW that quickly). This is big, because if you're used to adding stuff after the cycle has started, there's a good possibility that you forget to restart the machine upon reclosing it and you wake up the next morning to dirty dishes still sitting in there from last night. LG should consider changing the 4 second time to something longer, or maybe even making it a user adjustable setting. I almost kind of miss my old "fill it, close the door, and push the start button" machine. As far as drying goes, it's OK. I'm not in love with the new heated drying technology which is apparently the way most new "green" dishwashers are going and is not this product, or LG, specific. Simply put, plastic doesn't dry well. And, while they say one advantage with the new technology is that you can now put it down on the bottom rack without fear of burning/melting it, it's often too light and gets shot around in the tub during the wash cycles, so yu still really can;t put most plastic there. I miss my old heating coil. Cycle time: Varies depending on which options you select, and a full wash can be well over three hours in length (AUTO is just under three), to just under an hour. That was a big change for me -- 3 hours to clean dishes? Nothing critical there, just took a little "time" getting used to. Noise: Standing right beside it, the amount of starts/stops whizzes & whirs, and other noises the machine makes are intriguing. However, overall they are very quiet & you really can't hear them just a short distance away. And if anything else is going on, including a simple family conversation, you can barely even notice it when close by. A huge plus! Inside, the unit has some nice features but could add some simple common sense: Lower Rack: Lower rack is open and large so would seemingly fit a lot of dishes. It has four rows of movable alternating tines in the rack so, for example, in each row you can keep all of the tines pointing upwards & stack rows of plates "tightly" together, or you can lower alternate ones to accommodate larger serving dishes, platter, bowls, etc, or you can mix and match for varied loads. A really nice feature. Unfortunately, there are only four rows of tines and they're spaced fairly widely apart. There really needs to be at least 5 rows, if not 6, of them, to fully utilize the lower rack. Since dishes need two rows of adjacent tines to be held up, the four total rows of tines only allow two rows of dishes to be filled in the rack. Even when filled with oversized plates, about 20% of the lower rack is unused due to the wide spearation between rows. Total rack usage drops even lower, occasionally up to 40% unused space in a "fully loaded" rack, when smaller bowls, dessert plates, etc. are loaded. Now I can see LG trying to keep a little open space in this lower rack to allow for better water movement throughtout the tub, but it's way too excessive. I could fill my old dishwasher lower rack full with dishes from edge to edge and they always came out clean. Surely there's a middle road somewhere? Utensil Basket: Meh. Doesn't do a great job. Not sure if its the basket design (are holes in sides large enough to allow enough water flow through it), the mounting location at the side of the tub, or something else. All I know is I've never had to inspect each item of silverware for cleanliness after every load like I'm doing now. And, noting there's a full section in the owner's manual dedicated to how properly arrange each and every utensil into specific locations in the basket, you wonder if that's LG's best attempt at trying to rectify a known problem? Seriously. "Forks can go there or there, spoons need to go here, and knives can fill in here, here, or there." It's almost comical the attention paid to this. Seems like there has to be a better design. Upper Rack: The traditional upper rack is actually the middle rack in this dishwasher, which has 3. In general, its OK. The unique varied bottom has no flat areas and the angled tines rising from it take a little getting used to. I'm sure some engineer spent 100's of hours designing them to hold certain glasses in place at ideal angles with respect to water flow from the nozzles (e.g. the wine glass holders are nice), etc., but overall, our mix of glasses, tupperware, and other small items must be unique because they'rs routinely tipping, falling over, and generally not laying nicely in the rack. 3rd Rack: Kind of a gimmick and often not used (is easily removable), but does come in handy on occasion with large serveware, spatulas, etc., as well as keeping small stuff from flying around in the tub. Bottom line, it's a keeper. Nice looking, provides clean dishes, and mostly clean silverware. Wish it could hold more dishes in the lower rack and wish I didn't have to inspect every spoon before putting in the drawer. Maybe with our next one...

    Breaks down frequently

    This dishwasher does a fantastic job when it is working. I purchased the unit mid September. It stopped powering on at the beginning of December. The serviceman arrived within a couple of days and repaired the unit in a day or so after that. I am happy. It is now the beginning of February and the machine is again not powering on. It stopped working Monday, called early Tuesday morning, and I won't get a serviceperson out till Friday. Parts will have to be ordered which means I will not have a working dishwasher till next week. The unit is 4.5 months old and has broken down twice already. I spent what for me was a very large sum of money for a dishwasher because I wanted something that worked well and was reliable. My research showed that they were second behind Bosch for reliability and the layout on the machine is great. I love the machine when it works, but now I wish I had bought the bosch. I have no confidence in the machine any longer, and feel saddled with a $1,000.00 hand washing dish rack that won't drain.

    Works Great For Two Weeks

    If I could give zero stars, I would. I am on my second unit in under two months and now this one is leaking just as bad as the other unit. I am beyond my whits with this dishwasher and getting it replaced by Best Buy is a nightmare I wouldn't wish on anyone. To top that off I have water damage from the first unit and and after a month and a half I am stuck sending emails w/no replies to get it fixed. Today my second unit started leaking out the other side of where the first one did. I guess I get to call Best Buy, wait two weeks, hope I get a prompt replacement and hand wash all my dishes while I wait. Oh the joy! I forgot to mention I have a five month old and the copious amount of bottles that need cleaning makes not having a dishwasher flat out stupid. The process to replace my first unit was less than stellar and also not what I would expect based on prior experiences with Best Buy. Maybe my third unit will be the one that works...here's hoping!

    Good cleaner, so-so at drying

    As with almost all new dishwashers, this one struggles with drying. I found using the "Heavy Duty" and "Extra Dry" settings together always leaves the dishes dry, but it takes a long time for the cycles to complete. However, dishes are always clean and I don't do any scrubbing before putting them in. Also, I really like the phone app- I get notified when I need to add rinse aid, and when dishes are complete. A novelty, but makes it fun. Also the adjustable top shelf is SUPER useful. However the folding tines on the bottom rack always end up folding down and are a pain to keep upright.

    We bought this because the quiet ratings were almost identical to the Bosch 800 series which is almost exactly the same price. We had the Bosch at our last housed it was AMAZING!! The LG was part of a "Package deal" so we went with the LG. LG was rated 44db's and Bosch 42db's. SURELY 2 db's can't make that much difference! WRONG!! I can hear this machine over the tv in a completely separate room that is over 70 ft away from the dishwasher. VERY disappointed in this dishwasher. I wish I could upload a video so you could hear the machine while it runs. Pictures don't help in this situation.

    Very quiet

    The dishwasher is very quiet. I didn’t know if it was working or not the first time I ran it. It also cleans the dishes great and has plenty of room. The only down side for me is that I only have to run it once a week and it smells horrible from the dirty dishes. My old dishwasher did not smell like this one. I think it might be because the seal in the new one is much better so it just holds all the smell in. Plus, there is more space to put more dishes so it takes longer to fill up, which keeps the dirty smelly dishes sitting there longer.

    Great upgrade

    I upgraded from a Bosch and I’m really happy with that decision. Similar to a Bosch, it doesn’t have a heating element on the bottom for drying purposes, so I am used to that. Instead, the rinse cycle heats the water to a high temp and dishes dry faster. I love the third rack, but I removed the wine stem holders on the second rack to allow for more room. Syncing to my WiFi/LG app is a bonus. Somewhat unnecessary, but I do like that my phone gets an alert when the cleaning cycle is finished.

    Cleans well, a little noisier then my old one but it’s fine. It looks good. I like the lights inside the washer as it illuminates the dishes etc. the door feels a little light. Not as much heft to it so it feels a little cheaper. Not sure if the drying is working all that well but I haven’t been playing with the dry settings. I just hope it last longer then my old junky kitchen aid which is a brand I will never buy again.
