Description
This dishwasher lets you do dishes at the speed of life so you can conquer your daily chores in less time. 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 drying², delivering sparkling, table-ready dishes right off the rack.
QuadWash Pro
High-pressure jets with 38% more cleaning power³, spray dishes from multiple angles while soaking them with over one million microbubbles to help break down stubborn food residue.
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 steam to penetrate food residue and help eliminate water spots up to 60%⁴. LG dishwashers are National Sanitization Foundation certified and reach a final rinse temperature greater than 150°F when operated on the Steam cycle⁵.
EasyRack Plus
The EasyRack Plus system provides outstanding flexibility and convenience. It adjusts to just about any load of dishes to help ensure optimal cleaning. Easy to adjust on the fly, you can change the upper rack height to three different levels with one touch.
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
LG’s ThinQ app helps you manage your LG Smart appliance and more to make your day a little easier and keep your home running smarter. Compatible with Alexa and Google Assistant and available for iOS and Android platforms, this free app will help you run your home like a pro.
Glide Rail and Ball-bearing Wheel Design
Your heaviest dish loads glide in and out smoothly with the help of LG’s Glide Rail and Ball Bearing Wheel design. The Glide Rail keeps the upper rack on track while the ball-bearing wheel provides a smooth lower rack glide for easy loading and unloading.
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
Flex Zone lets you customize your cleaning to target different zones inside the dishwasher, including upper or lower rack only, and adjust wash intensity as needed for each zone.
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 technological advances, like the Inverter DirectDrive motor and the advanced 3-stage filtration system, were designed with quiet in mind. At 42dB, this dishwasher is among the quietest dishwashers in its class.
15 Place-Setting Capacity
The spacious, stainless steel interior provides ample space for lots of dishes and stemware, in a variety of sizes. Fit up to 15 place-settings of dishes.
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
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.
3-Stage Filter System
LG’s advanced 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.
