"Highest in Customer Satisfaction with Dishwashers"


Put Enhanced Cleaning in Motion

Achieve maximum cleaning throughout the entire cycle with LG QuadWash . With four spray arms instead of two, QuadWash also includes Multi-Motion arms that rotate back and forth while spinning. The high pressure jets power-clean dishes from multiple angles.


Think you have to check on the dishes" Think Again

LG smart dishwashers come with SmartThinQ® technology built-in, so you can get smartphone notifications when a cycle is complete. That means less waiting and more time to yourself. You can even check on the cycle status with voice commands using the Google Assistant and Amazon Alexa, so you don't have to lift a finger.


Count On It

When you buy a dishwasher, you want something reliable that you can count on. Because the Direct Drive Motor uses fewer moving parts and operates more efficiently, LG confidently backs the motor with a 10-year warranty.


Easy Loading & Maximum Flexibility

The newly-enhanced EasyRack Plus system provides outstanding flexibility and convenience, adjusting to just about any load of dishes to help ensure optimal cleaning performance. Easy to adjust on-the-fly, this racking system can shift to handle any challenge your dishes can serve up.


Quiet Operation

LG's technological advances, like the Inverter DirectDrive motor and the advanced self-cleaning filtration system, were designed with quiet in mind. At 44dB, this dishwasher is among the quietest dishwashers in its class.

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.

CHLC 7/12/2018

The wi-fi enabled feature is great It notifies me on my phone when the cycle is complete. I also like the top rack for spatulas and other large utensils. It is so quiet that it does not disrupt our conversations or other activities in the kitchen.

Great looking dishwasher

FranInBC 7/10/2018

Bought it 4 months ago. Found that I need to use the extra dry cycle in order for dishes to dry and not smell. I rinse food off the dishes before placing them inside. Ive still sometimes had food stuck on them after a wash cycle. I use the Cascade pods. Ive had the soap door not open during a wash or remnants of the pod still left in the soap container. Im using normal wash. Im satisfied but doesnt clean as well as my last dish washer that was at least 15 years old and still in working condition but looked it age.

Quiet and Roomy

Ccmbcm 7/8/2018

We are still getting used to loading our LG dishwasher. This machine is so quiet it is hard to tell if it it actually running Easy to navigate the various settings. Love the extra rack and have been using it mostly for flatware. The only reason we cant give 5 stars is because we are struggling a bit with the rack configurations and loading dishes in places where they will fit well.

Very happy with our purchase

cdsterling 7/8/2018

I cant really speak to long term performance as we have had it less than a month. But we love it. Even on Turbo which is a one hour wash it cleans everything we throw at it including dishes we would have pre-rinsed and wiped with our old dishwasher. As far as quiet operation yes I can hear it running. I dont understand how people could say that they dont hear it but it is the quietest dishwasher I have owned by a fair margin. The upper third rack is a great feature that is every bit as useful as we thought it would be. The hybrid drying system is very effective without a super-hot inefficient heating ring. Dishes that have a spot for water to sit on top will still have water sitting there but everything else is completely dry. The racks operate much more smoothly than on any other dishwashers we looked at and there is a lot of adjustment so you can customize to your preferences. Anyway my wife tells me every day that she loves this dishwasher. Im sorry if this sounds like a commercial but it is nice to buy something that outperforms your expectations at a reasonable price. The only thing Im not crazy about is how easily the stainless front gets fingerprints with our small children but I can live with that given how it performs. All in all this is the best dishwasher Ive used so I hope it holds up exactly forever. =

Viking69 7/7/2018

I have only had this dishwasher for a week but it is very nice quiet and easy to use. It is much larger inside compared to the 23 year old one it replaced. We laugh every time the little tune plays at the end of the cycle. What a fun surprise. I would definitely recommend this to anyone looking to buy a new one.

Overall Gets the Job Done

gchglobal 7/6/2018

Our old dishwasher stopped cleaning dishes to the point we would wash them by hand and run them in the dishwasher and they would be dirtier. Our non rinsed dishes come out spotless with this LG. Which of course is the main point and it does a great job. The flexibility of the three trays is excellent my only complaint is to fit our largest pots or cookie sheets we do need to remove one of the trays. Not the end of the world for super clean dishes

TERRIBLE

vlbh 6/26/2018

the worst dishwasher Ive ever had. It wont dry the dishes Ive had a metal spatula to rust and a cutting board mildew because it wont dry. It also smells so bad when you have dirty dishes in there and even after they have been ran and so called cleaned. Thats so un sanitary. Bring back the heating elements that actually dry your dishes and keeps it from smelling rusting and mildewing your dishes and utensils.

Amazing

Joce 5/8/2018

This dishwasher was extremely easy to install in the same space as my older one. After three weeks of usage of this LG dishwasher Im still amazed by how well thought of is the design of the interior and how much more the racks can take compare to my older one. Its a joy to fill this machine with all kind of soiled pots and pans as well as dishes and kitchen utensils and find everything spotless after the shim of the end of the cycle. The Auto and normal cycles are quit long two and a half to three hours but you can hardly hear the machine working. I also tried the faster cycles such as Turbo takes almost 60 minutes and the Express 30 minutes they are a little bit noisier than normal cycles but the results are almost as satisfying. The only thing that did not work for me is the Wi-Fi but I wouldnt take off a star of my evaluation because of that I still think this machine does an excellent job and deserve without hesitation the 5 stars. I hope Ill be able to enjoy this machine for many years to come and that I will not need to deal with the service department for a long time they couldnt help me much with the Wi-Fi issue anyway.

Greekladybug 5/5/2018

I am pleased with the 3 racks The soap dispenser could be reconfigured to fit the Finish pods. Instead of going in straight I have tilt the pod to make it fit. Otherwise it is a great product One more thing the silverware holes need to be a little bigger to accommodate European style silverware handles. They accommodate the spoons but not the forks knives handles. I got my SS set at Costco so it is not an unusual size. BUT for cleaning I think LG is the best out there

Nice design features underwhelming performance

Rw1270 4/28/2018

Own it for couple of weeks now used for around 15 times. I like the features I like the looks and design. Its nicely quiet. However it fails to impress in the most important category: cleaning and drying. Glass has spots left dishes have streaks pots have drops of water stuck to their surfaces. I use Cascade Platinum so cant blame it on the detergent. Wifi app is so basic that I see no point. If the price were low it would get more stars as Id rate it adequate but for this price I expected more - much more. If it were as simple as grabbing it and going to store I would definitely return it and ask for refund. I feel a bit stuck with it and underwhelmed so say the least. There are better choices.

Creppy 4/19/2018

Being a top of the line dishwasher we bought this over a similar speced and priced German brand dishwasher. Regret our choice now. Even on highest temperature- and soil setting and with Extra Dry mode turned on dishes come out dirty and dripping wet. Especially is this true for the top shelf where you stack cutlery. If not rinsed completely before running the machine food scraps will remain on your tools and tea stains in your mugs. Two stars for being extremely quiet ++ but not really doing a good job at what its supposed to do ---.

Its very quiet and cleans very well. The Wi-fi features is a plus but realistically useless. It doesnt allow you to control the dishwasher remotely.
