LDT7797BM-TurboExpressCycle_12-6-18-D1

Turbo and Express Cycles

Turbo Cycle will clean heavily soiled dishes in an hour using slightly more energy and water.*

What People Are Saying

Rated 5 out of 5 by from Quiet and clean First LG product I have purchased. Easy to install. Super quiet. Had to put my ear on the door to hear it. Washes dishes perfectly. Took a little getting used to placing dishes in racks however diminished with each use. So far very happy with purchase.

Rated 1 out of 5 by from So frustrated with this dishwasher I bought this dishwasher along with all the matching appliances due to a remodel. I have had problems with this since basically day one as it never really dries all the way. Right after purchasing it, I contacted service because there was always water dripping down the inside door when I open it and dishes were still damp. They had me up the amount of rinse aid that was being dispersed during the appropriate cycle. It helped it somewhat but still moisture in the DW. BTW I set it on auto, high temp and extra dry. So I have since been just putting up with the small amount of dampness. I have had it since December and now it sometimes does not turn on even though I can see the numbers count down and then I have had it where it stopped in the middle of one cycle as there was water in the bottom of the DW when I opened it the next morning. I cannot depend on it anymore. I ran a load and left town and when I came back it was super damp in there so I'm concerned of mold growing so now I can no longer leave it and come back days later. Another complaint is they say to just scrape off food and do not rinse. Did that once and will never do that again! Had to hand wash my dishes! I would not purchase this again!

Rated 3 out of 5 by from Okay This dishwasher has a good layout but my old one cleaned so much better. I would think for the price payed this would clean amazing. I have followed all rules and tips and still have dirty spots and it does not dry the dishes very well even with rinse aid.

Rated 4 out of 5 by from Love how quiet this dishwasher is! I bought this dishwasher a month ago and I am very pleased with how quiet the dishwasher runs. We love the stylish look of the unit and the special features such as the upper utensil tray; adjustable shelves; and interior lighting. My only complaint is that I don't feel that the unit gets the dishes dry enough even on the extra dry/night dry and high heat settings - hence, only the 4 star rating. Overall though, very pleased.

Rated 5 out of 5 by from Great dishwasher! I went through two brand new Maytags that were leaking out of the front door. Decided on the LG as a replacement and I couldn’t be happier. The door actually feels like it closes, the lights are awesome, and so far it cleans my dishes great. [This review was collected as part of a promotion.]

Rated 3 out of 5 by from Very Quiet I love how quiet it is but my dishes aren't getting as clean as they did in my old dishwasher (maybe because I haven't added the rinse aid) and also my dishes aren't drying at all (maybe because I have it on Econo Mode).

Rated 5 out of 5 by from Exceeding my expectations! Replaced our old dishwasher with this one because we liked the features like the third shelf, the collapsing holders, and the color. Didn't even realize it had lights inside, which is cool. We wanted a quiet dishwasher, but didn't expect it to be this quiet. Awesome! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great Expectations Met When we purchased this dishwasher it was our second choice, the other make was not available for 3 weeks and we need one quickly. I am so happy that the other make was not available. The dishwasher is excellent, quiet and the dishes come out with a shine and the fine stemware looks brand new. The results with "bad California water" is amazing [This review was collected as part of a promotion.]

Rated 3 out of 5 by from Beware Customer Service The dishwasher itself isn't bad: pretty quiet and cleans decently, but not great. The biggest issue is with LG's customer service and warranty. According to LG's own website, racks supposedly have a 5-year warranty on them. While this rack went bad after little more than a year, that's not the issue because things happen. The problem is the constant runaround we've had trying to get LG to fix it. At first it seemed simple, we called they sent us a rack...the wrong rack. When we called again and asked why, we were told that rack was sent because the rack we needed was out of stock. We were then told to call a few weeks later. So, we did. The rack is still out of stock, and we were told to call again in a few weeks. We do, the rack is STILL out of stock. They don't know when it's going to be in stock. We've had this issue with our old washing machine, too. Just putrid customer service.

Rated 5 out of 5 by from Super Quiet We purchased this one because our old one seemed to take forever to wash dishes. Plus it was too loud if we were trying to watch television in our open concept home. This dishwasher is so quiet that we barely know it is running. [This review was collected as part of a promotion.]
