Why Blend In When You Can Stand Out"

LG's exclusive MATTE Black Stainless Steel appliances give your kitchen an edge, with a unique matte finish that stands out from the rest. Now you can enjoy the innovation of LG, with an exclusive new look that will turn heads. Because the classics aren't for everyone.


The Look You Love Without the Fuss.

Now you can have all of the things you love about stainless, without the need for special cleaners or constant attention. LG's PrintProof fingerprint and smudge resistant finish easily wipes clean with a soft, dry cloth for a distinctive kitchen that handles real-life in style.


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.

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.

Efficiency...at a price.

BenjaminS 7/26/2018

We have owned this dishwasher only a month and like its physical features are great loading rack size height etc. However as a hybrid appliance no heating element the dishwasher doesnt dry the plates and plastic very well. The constant presence of moisture has caused a bad smell to develop after a couple of days. The owners manual and a placard on the dishwasher state you should not rinse your dishes. Clearly this worsens the smell inside the dishwasher between loads. I read in the manual that this is to ensure the soil sensor works properly. The instructions also say to clean the filters twice a month. That frequency of regular maintenance was a bit more than I expected. This is a very quiet appliance. Our dog doesnt even notice it which is amazing. We have only run it three times so far and we are starting to smell a slight rubber smell during the cycle. Not sure if thats an indication of a problem yet.

Nice upgrade to what I had...great features

MsAnn528 6/17/2018

So far I like it..only negative so far is a normal cycle takes 2 hours which is unnecessary so I use the turbo cycle which is only an hour. The top display is not usable as the countertop overlaps so I cant see it..but thanks to the wifi capability using the app I can monitor as it washes to know how much time is left which cycle is running etc. overall I really like it

DRYING ISSUES

Not for us 6/7/2018

We bought this not very educated on the new condensation drying process. I dont like it. It doesnt dry plastics well you MUST use a Rinse aid You cant just rinse and put dishes in for them to air dry - they NEVER dry like that even with the door slightly open. We dont have alot of dishes for the two of us and really like to use it as an open air dryer. Returned it...But it is VERY VERY Quiet.

Muzette 4/6/2018

I like the dish washer. It is quiet has lots of features some I will never use e.g. hook-up to WiFi I find this over kill. The utensil holder has a top cover w/slots where one slot holds one utensil. It can be cumbersome utensils get tangled and takes more time then just putting them in an open holder.

More wash settings than necessary

kreggie 2/20/2018

Why do designers keep adding bells and whistles to a product that really only needs a heavy normal and delicate cycle. This dishwasher seems to clean the dishes well but the lower rack could use more divider tines. The thought I guess is for large kettles to set unencumbered by tines - really kettles will set over tines. What about smaller storage containers smaller mixing bowls? These items need the support of tines. If I live long enough to need another dishwasher I will not get this style again.

OK

Steve review 2/18/2018

There are too many times too close together making loading of anything but flat plates difficult. Because the control. Panel is not visible when th3 door is closed no progress status is available. The lack of a heating coil for drying means the dishes do not completely dry if there is a rim. Because the door pops open for the last five minutes of the cycle means that heat and humidity is released to the room. The racks seem flimsy and do not smoothly return to closed position.

Our old dishwasher was 10+ years and we are happy to have a newer model. I love the different positions of the top rack and the utensils rack. I enjoy The quietness of this dishwasher but the water draining in my sink is a bit loud and annoying. I feel this dishwasher is on the smaller size from my old one as well. I am trying to learn how to best stack my dishes in my new machine. Overall I am happy so far and I am sure we will have many good years together.

Wow This Thing Cleans

Charlie57 2/4/2018

We replaced a worn-out dishwasher with this new LG. First of all its beautiful inside and out. Three racks a utensil holder that actually holds the items apart and that third rack that gives space for flat items and oversize spoons all of it works well to get our dishes cleaner. And a light in the dishwasher This is also a very quiet machine. With our kitchen open to the main living space the older dishwasher would overwhelm the sound. This one is so quiet that I dont hear it. We went with this LG after we had picked out another one a Maytag that the store didnt seem to be able to get. A friend recommended LG and how great it was. I changed the order to this LG and it has impressed me. I knew LG from electronics not for kitchen appliances. I am just amazed at everything this dishwasher has.

Own nothing but LG products. Have had no problems

JAG34 1/12/2018

In the past few months have bought refrigerator microwaveetc all LG products.The only problem I have with the dishwasher is the led and display that shows its done washing. we got in the habit of opening the door and letting whatever water is on the plastic air dry. If you do that the indicator lights go out.Other people dont know that its done and dishes are clean. Our old dishwasher kept the light on when you opened the door. Some people want to add dirty dishes to the already clean dishes. Minor problem. Bought a dishwasher status magnet to put on the door. Know we can use the night time drying option.
