LG's Leading 1-Hour Wash & Dry
LG's exclusive QuadWash(R) Pro and Dynamic Heat Dry(TM) technologies combine to deliver our leading 1-hour wash and dry cycle for sparkling, table-ready dishes in less time. So you can spend more time on what matters.


Pro-Level Cleaning Performance
Tackle post-dinner cleanup like a pro with the enhanced cleaning power of QuadWash(R) Pro. High-pressure jets with more cleaning power , 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.


Drier than Ever
Our Dynamic Heat Dry(TM) technology circulates hot air throughout the dishwasher for faster, more complete drying that won't melt your plastics, delivering sparkling, table-ready dishes right off the rack.


Built In Leak Protection 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 with ThinQ Care will alert you as soon as there is an issue.


Sleek Exterior Design
Top controls with LED display are easy to see and use when the dishwasher door is open but hidden from view when the door is closed, for a seamless look that's also easy to clean.


Resists Smudges for an Effortless Shine
PrintProof(R) 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.


ThinQ(R) Helps Make Life Happen
The ThinQ(R) app offers control and convenience to help you simplify life and enjoy the comforts of home. Control your dishwasher remotely or use voice commands with Google or Alexa voice assistants. Plus, download additional cycles and access Smart Diagnosis, customer support, and more. ThinQ Care(TM) sends usage, maintenance, and diagnostic alerts to help your appliances run smoothly. ThinQ UP(TM) appliances receive software updates for new features and enhancements.


A Convenient Spot for Hard-to-Fit Items
From flatware to long-handled utensils to mini tart pans, items that may otherwise need to be washed by hand finally have their place in the dishwasher. The convenient 3rd rack holds more items so you can save time and wash fewer loads.


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 so quiet that 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.


More Flexibility Means No Dish Gets Left Behind
EasyRack(R) 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.
