Product Features

Pro-Level Cleaning Performance

Tackle post-dinner cleanup like a pro with the enhanced cleaning power of QuadWash® Pro. High-pressure jets with 38% more cleaning power¹, spray dishes from multiple angles, while soaking them with over one million microbubbles to help break down stubborn food residue and provide exceptional cleaning performance.

Save Time with SteamAssist

No need to spend time rinsing or soaking dishes when LG SteamAssist gives you a hands-free head start. To activate, simply press the Steam button and the hot steam will help dissolve caked-on, baked-on food before the wash cycle ever begins.

Perfectly Flush for a Perfect Upgrade

Flush appliance installation is among the hottest kitchen trends, but rest assured the sleek, integrated design of this LG dishwasher will remain timeless. LG fits your space while fitting an impressive 16 place settings. It's an instant kitchen upgrade.

More Flexibility Means No Dish Gets Left Behind

EasyRack Plus® lets you fit more dishes, run fewer loads and make short work of after-dinner cleanup. With three height settings, the upper rack adjusts effortlessly and smoothly to make room for tall stemware on top or oversize pans below. Customizable tines offer greater flexibility for loading dishes of all shapes and sizes without compromising cleaning performance.

Resists Smudges for an Effortless Shine

PrintProof® finish resists fingerprints and smudges to keep your kitchen looking its best. Available in 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.

A Smarter Home Starts with the LG ThinQ® App

The ThinQ app offers control and convenience for smart LG appliances to help you simplify life and enjoy the comforts of home. Manage and monitor your dishwasher remotely, track and download cycles, connect with Google or Alexa voice assistants, and more. ThinQ Care appliances send usage, maintenance, and diagnostic alerts to notify you of potential issues like water leakage. ThinQ UP appliances receive software updates for new features and enhancements. Learn more.

No More Guessing

Now there's no more guessing when your dish cycle is complete. Floor status indicator projects a white light onto the floor just in front of the door to let you know when the cycle is finished.

Built In Leak Detection for Peace of Mind

ThinQ monitors water supply, drainage and leakage and will notify you if any issues arise after installation. Built right in for worry-free operation. Compatible models will alert you as soon as there is an issue.

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.

Enjoy a 2-year limited warranty on select appliances purchased through April 6, 2026 via the LG ThinQ® app. Terms apply.ᶲ
