Overview

  • 2-in-1 Washer/Dryer Combo
    Load, set and go. In as fast as 89 minutes, your clothes will be clean, fresh and dry¹, among the fastest ventless washer/dryer combos in the market. With the all-in-one design you can get laundry done while you get on with your day, without having to stop what you’re doing to move clothes between 2 machines.
  • 5.8 cu. ft. Mega Capacity
    Say never again to never-ending piles of laundry—this mega capacity washer/dryer combo is the largest front load all-in-one unit with heat pump technology² so you can fit more clothes in every load and power through laundry day in less time. How big is 5.8 cu. ft.? Big enough to fit a king-size comforter and more in a single load, for big time savings every week.
  • Sleek Ventless Design
    Space-saving 2-in-1 configuration, ventless design and standard 120v plug means it can be installed virtually anywhere. No detail was overlooked in this all-in-one’s sleek, modern style. The LG SIGNATURE WashCombo flat front design, brushed black steel finish and tinted, tempered glass door brings a premium point of view to your laundry space.
  • Dual Inverter Heat Pump Technology
    When it comes to powerful, reliable and efficient performance, there’s just no comparison. With LG SIGNATURE Dual Inverter Heat Pump technology, you’ll enjoy quiet operation and energy efficiency—using up to 52% less energy³. The low temperatures are easier on clothes and can help them look their best for longer.
  • LG ThinQ Smart Technology
    The LG 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/dryer combo remotely, track and download cycles, connect with Google or Alexa voice assistants, and access smart diagnosis, customer support and much more.
  • Built-In Intelligence: AI Fabric, Weight, and Soil Level Sensors and AI QuickLoadSense
    Forget about endless sorting or toggling through cycles—built-in sensors use AI technology to detect fabric texture, soil level and load size, then automatically select the right wash/dry motions, temperatures and more for advanced fabric care. With AI QuickLoadSense instant time display, estimated cycle time is displayed as soon as the door is closed.
  • Direct Drive Washing and Drying Technology
    Featuring a Direct Drive motor, this all-in-one combo provides even performance and precise tumbling motions that are extra kind to delicates. Based on the cycle you select, LG 6 Motion technology uses up to 6 different wash and dry motions, each designed to get clothes cleaner and help them last longer. Better than belt-driven motors—no belts, no pulleys, no worries. What else can you count on? The peace of mind of a 10-year limited warranty.
  • 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.
  • ezLintFilter
    Conveniently located right on top of the WashCombo All-in-One, the ezLintFilter design allows you to easily remove lint after every load. Simply push out the filter from its compartment and the lint can automatically be disposed into a wastebasket without manual removal.
  • Auto Cleaning Condenser
    Unlike some dryers that require manual cleaning of the condenser for optimal performance, LG SIGNATURE Auto Cleaning Condenser does the work for you. Using water extracted during the drying cycle and supplied directly from tap water, it powerfully flushes away lint and debris using jet sprays/multiple nozzles every time you dry for better airflow, better drying and enhanced energy efficiency—automatically.
  • Advanced Washing: TurboWash 360° / Allergiene Wash Cycle
    From mega capacity to top-of-the-line innovations, this all-in-one combo unit delivers the advanced cleaning performance you need. TurboWash 360° powers through laundry in less time, thanks to five jets with variable sprays that deliver a wash cycle as fast as 30 minutes⁴. The Allergiene cycle uses the gentle power of steam to reduce common allergens such as dust, pet dander and pollen in fabrics—perfect for bedding, baby clothes and more.
  • 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 cycles⁵ 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 refill⁶.
  • LG SIGNATURE SideKick Compatible
    Looking to run more than one load at a time? LG SIGNATURE offers the only all-in-one combo that’s compatible with the LG SIGNATURE SideKick⁷, which means you can add the mini pedestal washer and tackle two loads of laundry—both large and small—all at the same time. Discreet compact washer sits underneath the main machine and elevates the washer/dryer combo for easier loading and unloading.
  • LG ThinQ UP
    ThinQ UP enabled smart appliances may receive software updates for new downloadable features and enhancements to be sent wirelessly to the appliance. Choose which features you want and customize your appliance based on your lifestyle and personal preferences.
  • LG 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.
  • 2-Year Limited Warranty on All Parts and Labor
    All LG SIGNATURE appliances are backed by LG’s 2-year limited warranty, so you can confidently enjoy this appliance for years to come.
  • Dryer cords are not shipped with the dryer.
    It is the responsibility of the consumer to purchase the appropriate cord for their home.
