LG’s innovative QuadWash Pro and Dynamic Heat Dry technologies combine to deliver maximum cleaning coverage and thorough drying performance for clean and dry dishes, faster than ever before. That means you can spend less time waiting on dishes and more time on what matters. Plus, our TrueSteam technology helps to penetrate food residue, reduce water spots and sanitize your dishes.
1-Hour Wash and Dry
LG’s exclusive QuadWash Pro and Dynamic Heat Dry technologies combine to deliver a 1-hour wash and dry cycle¹ for sparkling, table-ready dishes in less time. So you can spend more time on what matters.
Dynamic Heat Dry
Our Dynamic Heat Dry technology circulates hot air throughout the dishwasher for faster, more complete drying, delivering sparkling, table-ready dishes right off the rack.
QuadWash Pro
Tackle post-dinner cleanup like a pro with the enhanced cleaning power of QuadWash Pro. High-pressure jets, 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.
ThinQ Care
Keep your appliances running smoothly with ThinQ Care, now in the ThinQ app. Get notifications about usage, maintenance, plus early diagnosis right on your phone. ThinQ Care will help you understand your appliance needs, avoid potential problems, and keep your appliance running its best.
TrueSteam with Sanitization
LG TrueSteam uses the power of steam to penetrate food residue and help eliminate water spots by up to 60%².
Plus, LG dishwashers are certified by the National Sanitation Foundation to reduce bacteria on dishes by 99.999% and reach a final rinse temperature greater than 150°F when operated on the Steam cycle³ for peace of mind.
Hidden LED Front Timer
Conveniently manage your time with a hidden LED display that counts down the remaining cycle time. When the dishwasher is not in use, the display disappears for a sleek look.
Height Adjustable 3rd Rack
Use the handy slider to adjust the 3rd rack height—even when fully loaded—make room for taller items at the last minute. Not only can you save time and wash fewer loads, it’s also a convenient spot for hard-to-fit items like flatware, utensils or small espresso cups.
EasyRack Plus
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.
LED Tub Light
Now you can check on dishes in an instant with the help of interior LED lighting. Two integrated tub lights turn on when the dishwasher door is opened, so you can easily check on your favorite mug.
Remote Start
Conveniently start your dishwasher remotely with the ThinQ app, so no matter where you are, your dishes will be ready when you need them.
ThinQ Technology
The LG ThinQ app helps you manage your LG Smart appliance and more to make your everyday a little easier and keep your home running smarter.
Glide Rail and Ball-bearing Wheel Design
Why waste time fighting a dishwasher rack that goes off track, especially when you’re in a hurry? The lower rack’s ball-bearing wheel design rolls out effortlessly—even when loaded with heavy pots and pans.
Flex Zone
Customize your cleaning to target different zones in the dishwasher. Set it to wash only the upper rack or lower rack, based on where the load is, or adjust the wash intensity to soft for the upper spray arm and strong for the lower, for just the right amount of pressure on each level.
Auto Cycle
With LG Auto Cycle, you have one less thing to think about. This feature automatically senses the level of dirt on your dishes and sets the wash cycle, so your dishes get optimal cleaning every time.
LoDecibel Operation (42 dB)
LG’s LoDecibel operation lets you run the dishwasher whenever you want with whisper-quiet operation.
Top Control Panel With LED Display
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.
PrintProof Finish
PrintProof finish resists fingerprints and smudges to keep your kitchen looking its best. Now you can have all of the things you love about stainless steel—the premium look, the professional-grade durability—without special cleaners or constant attention.
3-Stage Filter System
LG’s advanced 3-stage filtration system is tough on food residue and dirty dishes even if you don’t pre-wash. Plus its advanced design makes it extremely efficient and quiet.
