Overview

  • 29″ wide 5.8 cu. ft. Mega Capacity
    With its sleek aesthetic and streamlined design, you may not expect capacity that goes beyond the boundaries of a traditional washer. The massive 5.8 cu. ft. tub accommodates king-size bedding, comforters, oversized towels or washable rugs with ease, all while helping to save time by reducing the number of loads each week. At 29″ wide, it’s only slightly larger than standard 27″ models but still fits comfortably in most laundry spaces.
  • Modern Design and Touch Controls
    Go beyond ordinary buttons and dials with an intuitive 7″ LCD touchscreen that simplifies laundry and places total control at your fingertips. The elegant panel perfectly complements the modern, flat front design, luxe brushed steel finish and tinted tempered glass door.
  • Built-In Intelligence (AI Fabric Sensor / Smart Pairing)
    Forget about endless sorting or toggling through cycles—built-in sensors use AI technology to detect fabric texture and load size, then automatically select the right wash motions, temperatures and more for advanced fabric care. With Smart Pairing, the washer can even tell the dryer to select a compatible drying cycle, making it the ultimate laundry hack.
  • LG ThinQ Smart Technology
    The ThinQ app offers control and convenience for smart LG appliances to help you simplify life and enjoy the comforts of home. Manage and monitor your washer remotely, track and download cycles, connect with Google or Alexa voice assistants, and access smart diagnosis, customer support, and much more.
  • TurboWash 360° Technology
    With TurboWash 360°, you can clean larger loads fast and get more done while enjoying the same great washing performance you expect from LG. Five powerful jets with variable sprays surround clothes from multiple angles so detergent can penetrate deep into fabrics for a complete clean—even for big loads—in under 30 minutes¹.
  • ezDispense Automatic Dispenser
    No more digging out detergent and fabric softener every time you do laundry—with ezDispense Automatic Dispenser, just fill the reservoirs once and you’re set for up to 20 to 36 wash cycles² with the versatility of using detergent and softener or detergent only. It adds just the right amount for each load size—at just the right time—and will even send an alert to your smartphone when it’s time to refill³.
  • ThinQ Care
    Available within the LG ThinQ app, ThinQ Care sends proactive usage, maintenance, and diagnostic alerts to your smartphone, notifying you of potential issues and helping you keep your smart LG appliances running smoothly.
  • Tempered Glass Door with Dark Chrome Rim
    Real tempered glass door provides a sleek, stylish look that also resists shock and scratches. The dark chrome door trim offers a finished look that nicely contrasts the brushed steel finish and enhances the premium feel.
  • Cold Wash Technology
    Saving energy⁴ doesn’t have to mean compromising on cleaning with the Cold Wash option. Powered by the LG Direct Drive Motor and 6 motion technology, it’s ideal for cleaning all types of clothes—even those you normally wash in warm water. Can be used with almost any wash cycle and virtually all fabric types.
  • Direct Drive Motor 10-Year Limited Warranty
    Backed by a 10-year limited warranty, the LG Direct Drive Motor delivers peace of mind with every load. Fewer moving parts means less noise and vibration, greater stability and durable performance you can depend on for years to come.
  • ENERGY STAR Certified
    This LG high efficiency washer uses far less water and energy than a conventional washer for savings that add up with each load. Get additional savings with load-sensing technology that adjusts water levels and wash times or by adding the ColdWash option to almost any cycle.
  • LG SideKick Compatible
    Wash small loads that just can’t wait while cleaning a larger load in the main washer by adding the ingenious LG SideKick 29″ pedestal washer⁵. Controlled via the main washer’s touch panel, you can choose from warm and cold settings and 6 cycles to care for delicates, hand washables, workout wear and more. Elevate your possibilities—and elevate your washer for easier loading and unloading.
  • Closet Depth
    LG closet-depth⁶ washers and dryers are worth showing off, but when space dictates otherwise it’s good to know they’ll easily fit in almost any closet with plenty of room to close the closet door. Install the pair side-by-side, or get a stacking kit and install the dryer over the washer to save even more space.
  • NeveRust Stainless Steel Tub
    Unlike tubs made from porcelain or plastic, the LG NeveRust Stainless Steel Tub avoids the chips and nicks that can snag fabrics and ruin clothing.
  • Tub Clean System
    With the LG Tub Clean system, you don’t have to worry about mold, mildew or musty odors. Simply select the Tub Clean cycle, add liquid bleach or other cleaner and let the washer do the work to thoroughly clean and dry the tub, door and gaskets. Run it every month or so to help keep your washer—and your laundry—clean and fresh.
  • True Balance Anti-Vibration System and LoDecibel Quiet Operation
    Run the washer whenever you want— LG ‘s True Balance Anti-Vibration and LoDecibel systems are designed for quiet operation that keeps even big loads in balance to reduce washer noise and vibration. A must-have for main-floor or second-floor laundry rooms.
  • LG Pedestal Storage Drawer Compatible (29″)
    Sleek, sturdy bases elevate your washer and dryer off of the floor by more than a foot for more comfortable loading and unloading⁷. Slide the drawer open to find storage space for everything from detergent bottles to dryer sheets. They’ll even help you rise above laundry room clutter with a basket to keep it all organized.
  • Requires fill hose (not included)
    For standard hook-up upon delivery.
