Think you have to check on the dishes? Think Again
LG smart dishwashers come with ThinQ technology built-in, so you can get smartphone notifications when a cycle is complete. That means less waiting and more time to yourself. You can even check on the cycle status with voice commands using the Google Assistant and Amazon Alexa, so you don't have to lift a finger.
Powerful Cleaning, Fewer Water Spots
LG TrueSteam® saves the time and headache of prewashing or rewashing dishes by hand. A blast of steam at the start of the cycle penetrates and dissolves tough caked-on food but is gentle enough for your favorite wine glasses. A second blast during drying helps eliminate water spots by up to 60%*—no more having to wipe spotty glasses before guests arrive.
Do the Dishes at the Speed of Life
LG's exclusive QuadWash Pro and Dynamic Heat Dry technologies combine to deliver the industry's 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 Pro. High-pressure jets with 38% 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 technology circulates hot air throughout the dishwasher for faster, more complete drying*, delivering sparkling, table-ready dishes right off the rack—including hard-to-dry plastics.
Powerful cleaning, Fewer water spots
LG TrueSteam uses the power of steam to penetrate food residue and help eliminate water spots by up to 60%*. 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 66°C (150°F) when operated on the Steam cycle** for peace of mind.
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.
Easy Party Cleanup in Just One Load
This dishwasher’s generous capacity holds up to 15 place settings for quick cleanup in fewer loads. And with more in each load, you’ll spend less time washing dishes and more time enjoying the party.

Frequently Asked Questions by Customers
-
What is the “1-Hour Wash & Dry” cycle? Is it really washing and drying in 1 hour?
Yes — this model includes a cycle that washes and dries the dishes in about 1 hour by combining the Quick Wash segment with Dynamic Heat Dry™. It’s meant for when you want dishes ready quickly. -
What is QuadWash Pro and how is it different from regular dishwasher wash arms?
QuadWash Pro is LG’s enhanced jet/arm system that uses multiple high-pressure spray arms or nozzles to clean from different angles. It helps reach more areas and removes stubborn food residue more effectively. -
How quiet is the dishwasher? Will it be noisy in open kitchens?
It runs at ~40 dB, which is quite low—whisper-quiet. It’s designed to operate with minimal noise, making it suitable for open-plan kitchens or when people are nearby. -
Does it dry dishes well, especially plastics?
It has Dynamic Heat Dry as its drying system. While it does well, some users note that plastics often don’t dry fully, particularly in quick cycles, which is fairly common in many dishwashers. Using a full heat or more thorough drying cycle helps. (This is based on user feedback from Best Buy Q&A etc.) -
How adjustable are the racks? Can I fit large items like pots, pans, tall glasses, or stemware?
Yes. The upper rack is height-adjustable (3 levels), and there is a third rack for silverware / cutlery. The lower rack has fold-down tines, and there are stemware holders. This flexibility helps accommodate tall items or irregular shapes.
