Textured Steel™ Finish

The LG SIGNATURE dishwasher merges the exquisite Textured Steel™ Finish with our sturdy and sophisticated LG stainless steel technology.


Stainless Steel Touch Panel with LED Display

Sleek controls make it easy to select the settings you want, while the LED display provides every detail at glance.


EasyRack™ Plus

The EasyRack™ Plus system adjusts to just about any load of dishes to help ensure optimal cleaning performance. With one touch, you can change the height of the upper rack to three different levels. Easy to adjust on-the-fly, this racking system can shift to handle any challenge your dishes serve up.


Height adjustable 3rd rack

The height adjustable 3rd rack gives you more space to fit everything from long flatware to small espresso cups.


Glide Rail and Ball-bearing Wheel Design

Even your heaviest dish loads glide in and out smoothly with the help of LG's Glide Rail and Ball Bearing Wheel design. The Glide Rail keeps the upper rack on track while the Ball-bearing wheel provides a smooth lower rack glide for easier loading and unloading.


Dual Zone Wash

This feature enables water to spray with two different intensities at the same time. Gently wash delicate dishes on the upper rack while simultaneously power washing heavy-duty pots and pans on the lower rack.


ThinQ®

Stay connected with features like Smart Access and Smart Adapt, which allow you to monitor your dishwasher remotely and download new and improved cycles. In the unlikely event that you have any problems, Smart Diagnosis helps you troubleshoot problems quickly and efficiently.


TrueSteam®

LG TrueSteam® saves the time and headache of prewashing or rewashing dishes by hand. A blast of steam at the start of the cycle penetrates and dissolves tough caked-on food, but is gentle enough for your favorite wine glasses. A second blast during drying helps eliminate water spots by up to 60%*- no more having to wipe spotty glasses before guests arrive.

*Percent in water spot reduction compared to comparable LG non-steam dishwasher on delicate wash cycle. Results may vary by model. Results based on test with LG LDF7774ST as of Feb. 2018.


LoDecibel™ Operation (38dB)

Doing the dishes shouldn't keep you up at night. LG's technological advances, like the Inverter Direct Drive Motor and self-cleaning filtration system, were designed with quiet in mind. At 38dB, this dishwasher is our quietest on the market.


QuadWash™

The QuadWash™ with Multi-Motion spray arms combined with the Inverter Direct Drive motor power cleans dishes from multiple angles to reach every nook and cranny.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Does not dry.

Triple J 11/9/2021

I bought this about a few months ago and I am not happy at all. Unless the food is wet it doesnt come off. If you had something with color in a white bowl the color stays on the bowl and you have to hand wash it to get it off. I have white dishes. The dishes always have to be dried when you open it no matter what setting it is put on. When it shows END the machine sounds like it is still running. I run my dishes at night and am not happy that in the morning it sounds like its still running. I am very unhappy as we paid top dollar for this machine thinking it would be wonderful and we have been VERY DISAPPOINTED

Nice machine sketchy loading racks.

Retired hubby 10/5/2021

I purchased this to replace my 13 year old Kenmore Elite which I liked very much and at the time had the lowest Db rating available. This LG machine has a listed Db rating of 38 and indeed is very quiet. Installing the sound proofing materials was problematic due very poor instructions. Fortunately I found a You Tube video which clarified it. The machine does a fine job of cleaning my dishes and as I mentioned is very quiet. I also like the lighted tub. The rack system is very poorly designed. When attempting to load bowls or saucers on the middle rack the foldable tines constantly collapse and thus the dishes need to be gingerly reloaded. The silverware caddy has a large handle in the middle which is in the way of some of the silverware compartments and makes loading more of a hassle than it should be. I like the dishwasher but LG should redesign the racks.

Extremely quiet

TammyLyn 8/15/2021

We just renovated our kitchen and our old 25+ year old Kitchenaide dishwasher that still worked great did not fit in with the remodel. I decided to go with this LG model and we are amazed at how quiet it is. It took us a few washes to get the drying part to our liking. All in all we are very satisfied with this purchase.

LG Signature dishwasher

Brown2 8/3/2021

I had to replace my 12.5 year old LG steam dishwasher because the control display panel stopped working and the part was no longer available I was told parts are only made for 7 years. I wanted a quiet model and this one seemed to be rated as the quietest. Ive only used it a couple times. I like the bright interior light and the racks work great they are better designed than the previous model I had. Im not sure how well it cleans yet and need a few more times running it. So far it doesnt seem to clean better than my previous machine. There are special drying cycles my previous model didnt have. I like the fingerprint-resistant finish and integrated handle. It sticks out a little further than my other dishwasher did and Im not sure why because the specs seem to show the same depth. This seems to be the most expensive model and I probably would have gotten something less expensive if there was another model as quiet as this one. I dont need a Wi-Fi enabled machine.

The Wife is Happy

BigOH 6/28/2021

We have always bought the top of the line Kenmore Dishwashers. The one we had still worked great after 15 years but we were remodeling the kitchen and the old one did not match. After looking at what seemed liked a hundred different dishwashers my wife said this was the one she wanted. I was afraid it would not live up to her expectations. I was wrong. She is so happy with the quietness and the results that you could not remove this dishwasher if you wanted to.

Very Quiet so that is the plus

Mike in GBVA 3/23/2021

I bought this a couple of months ago and already had to have the repairman in to fix an issue that kept us from using it for 2 weeks. Also the other problem is that it does NOT get everything clean. So we have to prewash/rinse off most of the dishes and utensils before putting in dishwasher. We had an old 25 year + dishwasher in our other house and never had any problem with getting the dishes clean with NO rinsing. why cant newer products work the same.

Excellent machine

tkpm 3/5/2021

We purchased this dish washer about a month ago. The price made us hesitate for a moment but after reading about all its features we decided it would be worth it. We have not been disappointed It is quiet dishes come out sparkling with little or no scraping or rinsing. We like the finish as fingerprints are much less visible than our previous stainless- finish dishwasher. We would definitely recommend the LG Signature

Very quiet dishwasher with interior tub LED lights

TJKA 2/10/2021

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. Its 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 didnt 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 dont 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.

The machine

Eddie Cie 2/4/2021

Have used this dishwasher just a bit less than a month. Very quiet but time to clean is a bit long. Longer than our past dishwasher. So only draw back long washing times.

Truly quiet dishwasher

old guy cc 1/11/2021

The dishwasher is very quiet and has a smudge-free stainless finish and clean lines. Dishes and glassware sparkle after cleaning. The real test was dried on canned cat food bowl. It always requires overnight soaking to come clean. The LG rendered it shiny and spotless with no soaking or scraping.
