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 rackincluding 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 66C (150F) when operated on the Steam cycle** for peace of mind.


Make room for last-minute items

Use the handy slider to adjust the 3rd rack heighteven when fully loadedto make room for taller items at the last minute. Not only can you save time and wash fewer loads, its also a convenient spot for hard-to-fit items like flatware, long-handled utensils or small espresso cups.

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.

Brilliant visiblity

Check on your dishes 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 favourite mug.
