Load, set and go. In as fast as 89 minutes2, your clothes will be clean, fresh and dry, making it the fastest among 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. - Go-Anywhere 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. - Greatest Energy Savings.
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. - 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, 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.

Simply push out the filter from its compartment and the lint can automatically be disposed into a wastebasket without manual removal. - One Less Thing To Worry About.
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 With LG’s Best Cleaning System.
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 in as fast as 30 minutes4. The Allergiene® cycle uses the gentle power of steam to reduce common household allergens such as dust, pet dander and pollen in fabrics—perfect for bedding, baby clothes and more. - The Ultimate 3-in-1 Laundry Set-up, For Small Loads That Are A Big Deal.
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 SideKick®7, 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. - A Smarter Home Starts With The LG Thinq® App.
The LG ThinQ® app8 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.
