Description

4.5 cu. ft. Ultra Large Capacity Smart Front Load Washer


Product Features

  • Get A Custom Clean
    Based on the cycle you select, LG 6Motion™ technology uses up to 6 different wash motions, each designed to get clothes cleaner and help them last longer. Options range from a scrubbing PowerMotion that helps to dissolve stains to the gentle Swinging motion that’s ideal for delicates.
  • Cleans Like Warm, Saves Like Cold
    Saving energy doesn’t have to mean compromising on cleaning with the ColdWash™ 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.
  • Built-in Intelligence Takes Out The Guesswork
    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.
  • Count On Quiet, Efficient Performance
    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.
  • Go Big To Save Time And Get More Done
    Say never again to never-ending piles of laundry—this ultra large capacity washer fits more clothes in every load and helps you power through laundry day in less time. Bring on big loads of towels or jeans -this 4.5 cu. ft. washer fits more in every load up to 20 lbs.
  • Smooth Surface Helps Prevent Snags
    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.
  • More Style, Less Space.
    LG closet-depth washers and dryers have a shallower depth to fit in more places & add sleek style to any room.
  • Wash Two Loads At The Same Time
    Add the one-of-a-kind LG SideKick™ pedestal washer¹ and wash small loads that just can’t wait in the compact washer below while you do a big load up top. Warm and cold settings and 6 cycles let you care for all types of items, from delicates and hand washables to workout wear and baby clothes. Elevate your washer for easier loading and unloading.
  • A Smarter Home Starts with the ThinQ® app
    The ThinQ® app² 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 more. ThinQ Care appliances send usage, maintenance, and diagnostic alerts to help you keep them running smoothly. ThinQ UP appliances receive software updates for new features and enhancements.
