Features & Performance

Built-In Intelligence uses AI and sensors to detect fabric texture and load size, automatically selecting optimal wash settings
SmartThinQ Wi-Fi lets you start, stop, and monitor cycles remotely from your phone
Smart Pairing, set up through the ThinQ app, lets this washer tell a compatible LG dryer which drying cycle to use
Allergiene cycle uses steam to help reduce common household allergens in bedding, baby clothes, and more, and is AAFA certified
ThinQ Proactive Customer Care can flag potential issues and suggest fixes before they become bigger problems
5.0 cu ft Mega Capacity comfortably fits large loads, including bulky items and king-size bedding

This washer focuses on large-capacity washing combined with AI-driven smart features rather than a compact or budget-first design. It's built for households that want a full-size, high-efficiency front load washer with the convenience of app control and automated settings, in a sleek Black Steel finish.

Reality check: Smart Pairing, remote start/stop, notifications, and proactive diagnostics all require connecting this washer to your home Wi-Fi and registering it in the LG ThinQ app; Smart Pairing specifically also needs a compatible LG dryer registered the same way. As a high-efficiency front load washer, always use HE detergent — regular detergent can cause excess suds and affect performance. At roughly 27" wide and 39" deep, it has a larger footprint than compact 24" washers.
