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.

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.

  • Height Adjustable 3rd Rack

    The height adjustable 3rd rack gives you more space for hard-to-fit items.

  • Smooth Operator

    Even your hardest dish loads glide in and out smoothly with the help of LG’s Glide Rail.

Smarter Washing

SmartThinQ® technology lets you stay connected with features like Smart Access and Smart Adapt, which allow you to monitor your dishwasher remotely and download new cycles. Smart Diagnosis helps you troubleshoot quickly and efficiently if needed.

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.

What People Are Saying

Rated 5 out of 5 by from Works fantastic t I bought lg three door refrigerator and lg stove. But to my horror they had no dishwashers without handles available most places including where I purchased them at said they were discontinued. Very unhappy. Because I can't have a handle on dishwasher. Well I waited a few months trying to buy one online bc they would say they have one but in end they didn't. So I kept looking. Finally Lowes showed they had them. I went straight to Lowes and ordered one. It is really nice works wonderfully super quite. The only thing it doesn't have is steam clean. That was an option I really wanted but alas they did discontinue that model. Over all the one I have is great. Would recommend to anyone this is a good dishwasher. Third rack is great addition Thanks.

Rated 5 out of 5 by from Is it on??? This is the quietest appliance I have ever owned and I am 61. I had to keep checking to be sure it was on. I live alone so it has taken me weeks to try all the settings. The choices are amazing..I almost wish I had a larger crew to otcook for. I love the adjustable shelves and the adjustable dish holders. up to stack dishes and down for pots and baking dishes. There are four slots in the utensil basket and I have put them in uniformly. It makes emptying the dishwasher as easy as it is to load it. It replaced a basic washer I bought when I bought this house and if I knew this was going to be so great I would have bought it years ago. Next I am getting an LG room portable air conditioner Love the products and the features they provide.

Rated 5 out of 5 by from Very Happy with this choice We found this LG on sale while out looking at another brand. I looked at the reviews and noticed the satisfaction areas were similar to what I look for and the features sold me. I want clean dishes without having to wash them beforehand. I want power and silence. I want the water to get everywhere because I have a lot of odd shaped things and I want the little packet of soap (I use the finish tabs) to fall out and dissolve, not get stuck in the holder. Looking at the design answered many of those issues. The racks are adjustable. I LOVE THAT. The third rack seemed iffy to me. I didn't think anything would get clean but I have not had to rewash anything I put up there yet. Not only does it have it's own water sprayer but one side drops down for larger items like measuring cups. Very useful for light items that usually end up in the bottom and long utensils that don't fit well in the silverware spot. The bottom sprayer has 4 arms that are better made than most of the plastic types. This is the most quiet dw I have had to date. But I'm sure most are quiet these days. The cycle is long but there is a quick wash that is under an hour and does just as well. I'm more concerned with not having to check every cup for dirt as I unload than with the cup still being a little wet. But the full cycle completely dries the dishes from what I have paid attention to. Sum up: Its a good machine. It cleans well and is quiet. It has extra features that I thought would mean nothing to me but that I now use regularly. There are many different cycles and I haven't really messed with them. I just hit start and walk away. But I'm pretty happy with it so far. I'm glad we bought this instead of something more expensive.

Rated 4 out of 5 by from Well built, great features The quietest dishwasher I have ever had. Solidly built, very smooth bearings on the racks. First rate quality

Rated 5 out of 5 by from Work of Art We received our dishwasher a week ago and used it several times so far. I can honestly say visually it is a work of art for an engineered dishwasher. Much more elegant than our old one. So far we rate it very high. The positives include a stainless interior, it washes dishes and glasses extremely well, has multiple settings and cycles to help be more green, and it completely dries the dishes. A couple negative things include the fact that taller glasses don't work in the middle shelf because they hit the small top rack and the front panel shows a lot of fingerprints. These issues are minor compared to the overall quality of the machine.

Rated 1 out of 5 by from Finish flakes off Spent 5 thousand dollars on black stainless appliances 14mos ago. The black scratches very easily and is very noticeable but the real issue is the black finish is actually flaking off of three appliances. Told too bad out of warranty. It like buying a car and the paint flakes off. Do not by Black stainless steel.

I recently purchased the white colored one, the metal base is black, do you sell that piece in white?  If not, what type of paint do you recommend I use to paint it? 

Asked by: Bryanguy
We appreciate your interest in this dishwasher. Unfortunately, the metal base would only come in black. Also, we would not have any recommendations to offer for painting the base.

When will this dishwasher be available?

Asked by: PapaJ
Not anytime soon. I already paid for my dishwasher at a local Lowe's and apparently they haven't even made them yet. Can't get a straight answer from LG if they are made or still in design phase.
