Matte Obsession

LG's exclusive MATTE Black Stainless Steel combines the timelessness of stainless steel with a luxe & low-gloss, matte finish that complements any kitchen décor. It blends well with other matte finishes or provides a dramatic contrast to gloss surfaces, delivering impressive functionality and understated elegance.


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.


Four Reasons to Buy an LG Dishwasher


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.

Why NSI Protection Plus?

Our service plan is an economical way to extend the terms of your product's manufacturer parts & labor warranty.

Most manufacturer's limited warranties leave customers with no protection against the rising cost of repairs.

Even the best products can malfunction and the most minor repairs can cost hundreds.

About NSI Protection Plus

Administered by Warrantech and insured by AmTrust Financial, NSI Protection Plus is the largest service network in the industry with 30 years of building the network and over 22 million in paid claims.

The most comprehensive repair plans in the business!

  • Day one coverage on special features
  • Removal and reinstallation coverage
  • $25 Laundry credit (Washers and Dryers)
  • 5 year appliance contracts include 10 year major component coverage
  • $250 Food credit (per incident, eligible products)
  • The only true "No Lemon Guarantee" in the business
  • No "CAP" on repairs or replacement, unlimited repairs.

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.

Very unhappy

TW47 9/6/2023

It is 3 years old and the soap dispenser broke. I used it probably 1 to 2 times a week. I dont use it at all now. The LG repairman saidjust throw the soap tablet in and that does not work. I am having to replace the dishwasher.

The last LG appliance I will ever buy

Greg96 9/2/2023

I bought this product approximately 5 years ago. I am replacing it this month. That will make this the shortest-lived dishwasher I have ever experienced. By the end of its life not only would the dishwasher not drain it wasnt clogged but it seems the control board was dying as well. To use the dishwasher usually meant flipping the breaker for the circuit on which it was attached to reset the electronics. Looking online it seems I am not the only person with the problem with the electronics. When the dishwasher worked it worked fine. It was silent and cleaned the dishes well and I liked the three trays and ability to move the glasses tray up and down to accommodate larger items in either the bottom or middle trays. But none of that matters if the dishwasher does not last. I would not buy another.

So Very Quiet

Marsha P 8/21/2023

The first time I ran this dishwasher I opened it up three times because I couldnt figure out why it hadnt started. It had started it was just that quiet. Its amazing to me that something like this can run and I can be standing right next to it and not even know it. But thats this dishwasher. I love the upper shelf I love the adjustable second shelf and it cleans like a dream. But back to being quiet. I was standing next to it talking to a friend in my kitchen and they asked if they should start the dishwasher. They couldnt believe it when I said it was already running I may have won a convert.

Cleans the dishes great when it works

Blankscan 5/17/2023

Sleek looking lots of features ample room for dishes but randomly decides when it wants to turn on and off. Sometimes it works fine other times it doesnt respond for weeks or months at a time.

So awesome I designed my kitchen around it

Regina G 5/1/2022

I bought this 3 years ago for a deep discount as a last year leftover. Im so thrilled with it. Hubby thought it was broken it is so quiet. I red did .y entire kitchen ripped out all the wallsfloor ceilingand all new appliances but I loved this so much its the only thing I kept from the old kitchen. Had a bit of rust on top and bottom rack and LG replaced free of charge. Had a crack on my control panel and the Lowes warranty replaced at no charge. Best dishwasher Ive ever had Great customer service both LG and Lowes.
