Quick Specs
Redesigned with Style in Mind
This new style takes your kitchen next-level with a fresh, contemporary look. Restyled bar handles are slightly contoured to comfortably fit your hand.
Pro-Level Cleaning Performance
Tackle post-dinner cleanup like a pro with the enhanced cleaning power of QuadWash(R) 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.
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.
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.
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.
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.

Manage and monitor your dishwasher remotely, track and download cycles, connect with Google or Alexa voice assistants, and more.
