Certified to Sanitize

All LG dishwashers are certified by the National Sanitization Foundation (NSF) to reduce bacteria found on dishes by 99.999% and reach a final rinse temperature greater than 150°F when operated on the Steam cycle of TrueSteam dishwashers or the High Temp Cycle of other LG dishwashers*. So you can clean and sanitize your dishes with confidence.

Get a Spotless Clean the First Time

LG's exclusive QuadWash™ technology gets dishes clean the first time. With four spray arms instead of just two, QuadWash™ uses Multi-Motion arms that rotate back and forth while spinning to power-clean dishes from multiple angles throughout the entire cycle.

Beautiful tables start with beautiful dishes

Dynamic Dry™ technology on all LG dishwashers delivers faster, more complete drying. So you get drier dishes for a more dynamic table.

Resists Smudges for an Effortless Shine

PrintProof™ finish resists fingerprints and smudges to keep your kitchen looking its best. Available in matte black, 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.

Clearly in Control

Fully-integrated into the top lip of the door, LG's sleek controls make it easy to select the settings you want, while the LED display provides every detail at a glance.

Step Up to the 3rd Rack

The 3rd rack gives you more space to fit everything from long flatware to oversized cooking utensils including spatulas, spoons, tongs and more.

So Quiet, You Can Use Your Indoor Voice

Now you can run the dishwasher whenever you want-day or night. The 46 dB cleaning cycle is whisper-quiet, so you won't have to worry about interrupting post-dinner-party conversations or naptime. Especially important for homes with open floor plans where sound readily travels from room to room.

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.

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 and 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.

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

I dont like it

Submitted by hilew - 10/22/2020

I hated my old dishwasher and was soo excited to get a new one. I purchased this online and installed it a couple weeks ago. Its quiet which is great. Looks good. I do like that you can select a half load cycle. You select whether you want the top rack or bottom rack to be washed. BUT the dish supports spacing in the lower rack is terrible. It seems like its missing a row of supports. I end up with an empty space in the middle of the rack because isnt anything there to support dishes bowels or whatever. The spacing is just all wrong. Also you have to enable the extra dry setting otherwise every comes out very wet.

Poorly Designed

Submitted by jeanblt - 10/13/2020

I feel the racks were poorly designed which results in not being able to make maximum use of the space in loading the dishwasher.. The silverware basket is poorly placed and takes up way too much space.

Nice wash very clean and dries well

Submitted by Maverick1138 - 9/30/2020

We have had this dishwasher for a year and a half it is performing well and the WiFi feature is a nice to have. The only downside is the rack is rusting out already. There are patches where the plastic coating has dissolved to a rusty area. Now we are contemplating a new rack. With only 1.5 years the rack shouldnt dissolve like this. Also the lettering on the controls have also dissolved in some spots. That may be due to the rinseaid we use but still the engineers should have tested that.

Wish I still had my old dishwasher

Submitted by Pamela150 - 8/21/2020

Have had this dishwasher for 2 months and it will not dry the dishes not matter what setting I use. This is just half of a dishwasher. I thought I was purchasing a quality product. Hate it.

Washes good. Dries terrible.

Submitted by cacka - 7/16/2020

Does a good job washing but dries terrible even using extra dry or night dry. Leaves the insides wet and if you wait a few days until you have a full load the water stagnates and smells terrible. Dont recommend.

Not as shown

Submitted by Astone - 5/18/2020

This dishwasher shows finished sides and top. We bought this because we dont have cabinets and thought we were purchasing what is shown in the pictures. The pictures show stainless sides and top. When it arrived the sides and top were exposed. Nothing like the picture. Very disappointed as we bought this specifically for this purpose.

Quiet but ......

Submitted by Flicka - 5/15/2020

I have used my LG QuadWash dishwasher for a year. I was very excited at first because it is VERY quiet. The reality set in very quickly - my dishes never get dry. I had it looked at by a company representative and was told that I would have to live with wet dishes if I didnt want to use a rinse agent. I dont like the taste that is left behind by the rinse agents I have tried in the past so I hurry to open the machine as soon as it finishes so they will air dry. Then I tried to clean the filtration system. I have always cleaned my dishwasher filtration system weekly because I know what builds up in them. This one fills with grease quickly and is ABSOLUTELY IMPOSSIBLE to clean. All my previous dishwasher filtration system filters came apart for easy cleaning. This one does not come apart and requires that you have a very long thin brush that has long bristles on the top and the sides to be able to reach all the nooks and crannies. I havent found a brush yet that will actually clean the filter. I have tried immersing it in boiling water with lots of dish soap and it still requires major brushing. All in all I am extremely sorry I purchased this dishwasher - mainly because of the filtration system.

Looks Great Just hope yours doesnt breakdown.

Submitted by Unhappy2020 - 1/28/2020

I bought this in April 2019. Loved it. Quiet worked pretty well for 6 months. Then it went down hill. The machine started throwing error codes. Multiple calls to support with solutions. None of which worked. Warranty service techs HAVE to be scheduled through LG. Took 2 weeks to get someone to come look at it. Turned out to have a cracked motor and bad sump pump. Problem diagnosed...finally. But have been on back order for over 6 weeks Worst service experience ever.

PrintProof still shows fingerprints

Submitted by JulieColl - 1/9/2020

The dishwasher is advertised as PrintProof but it still shows smudges and fingerprints. I would not recommend if that matters to you.

Why does the light turn off??

Submitted by Meteorologymike - 12/25/2019

Great dishwasher But why does the light turn off after 30 seconds? Why does the light turn off at all? Who has the door of the dishwasher open when they arent loading and unloading? This would be an easy improvement for future models.

Very Loud

Submitted by MRDe - 11/23/2019

Bought this dishwasher to replace a Kenmore with same sound rating. The LG is much much louder. Very disappointed.
