Do the dishes at the speed of life

LG's exclusive QuadWash® Pro and Dynamic Heat Dry™ technologies combine to deliver the industry's leading 1-hour wash and dry cycle* for sparkling, table-ready dishes in less time. So you can spend more time on what matters.


Make room for last-minute items

Use the handy slider to adjust the 3rd rack height-even when fully loaded-to make room for taller items at the last minute. Not only can you save time and wash fewer loads, it's also a convenient spot for hard-to-fit items like flatware, long-handled utensils or small espresso cups.


More flexibility means no dish gets left behind

EasyRack® Plus lets you fit more dishes, run fewer loads and make short work of after-dinner cleanup. With three height settings, the upper rack adjusts effortlessly and smoothly to make room for tall stemware on top or oversize pans below. Customizable tines offer greater flexibility for loading dishes of all shapes and sizes without compromising cleaning performance.


Brilliant visiblity

Check on your dishes with the help of interior LED lighting. Two integrated tub lights turn on when the dishwasher door is opened so, you can easily check on your favorite mug.


Resists smudges for an effortless shine

PrintProof® finish resists fingerprints and smudges to keep your kitchen looking its best. Available in black and classic stainless steel, now you can have all of the things you love about stainless steel appliances-the premium look, the professional-grade durability-without the need for special cleaners or constant attention. Plus, it easily wipes clean with a soft, dry cloth.


Life's better when your home runs smart

Discover ThinQ Care within the ThinQ app - proactive smart alerts to keep your appliances running smoothly. Get notifications about usage, maintenance, plus early diagnosis right on your smartphone.*

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

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.

Installation

RB21 3/16/2023

I have had the dishwasher a couple of weeks now. It is quiet and works well. One thing you should know about installation is the unit is 25 inches in depth so it sticks out beyond a standard cabinet.

The perfect dishwasher

Burst3 3/15/2023

My last dishwasher was just not getting the dishes clean as I wished. I decided to replace it with another LG dishwasher and after the first wash I realized I had made the right choice. The dishes were perfectly clean dried and sparkling fresh. Good no GREAT choice

Nice dishwasher

Mrkcrsll 2/14/2023

We have our LG dishwasher about a month now. It is extremely quiet and does a great job. There are LED lights on the inside which I thought was great the first time I saw them and it is a great feature to have when loading and unloading the unit.

Exceeded expectation

MommaZ 1/14/2023

Ive been an owner of two sets of LG washers/dryers for the past 20 years. Neither set has/had problems and therefore I am updating my kitchen with LG appliances. This dishwasher is super quiet and does an amazing job with the dishes. I would highly recommend this model to anyone who is looking for a dishwasher.

Bought this newer model based on recent high marks

jon2u2 1/4/2023

Bought this newer model based on recent high marks from online reviewer for highest reliability for LG dishwashers. So far have only used a few times. I must admit theres still a leaning curve at least for me due to all of the bells whistles including Wi-Fi interface. Also big change from older models simpler start-up and lack of so many options. However so far seems to do a very nice job of cleaning. Love the interior lights and third rack.

Great features controls and ThinQ illogical

J Boris 12/24/2022

A very quiet machine with nice racks lights and steam. Drying is disappointing- but apparently this is not unique to LG. The controls are confusing at first- should be intuitive. Linking the ThinQ app is elusive couldnt find the right barcode to scan and the link instructions to WiFi very poorly written. The manual is generic too many models. Not as satisfying as the LG washer.
