LG Smart Front-Load Washer 5.0 cu. ft. with Wi-Fi and ThinQ (WM4000HWA)
8.6/10 — A spacious, smart front-loader that blends genuinely useful app control with fabric-friendly washing, making it an easy recommendation for busy large households.
Overview
The LG Smart Front-Load Washer 5.0 cu. ft. with Wi-Fi and ThinQ (WM4000HWA) is a high-capacity front-loading washing machine aimed squarely at larger families who do laundry in volume. With a 5.0 cubic foot drum, it can swallow bulky loads like comforters and multiple days' worth of clothing in a single cycle, reducing the number of runs you need each week.
What sets the WM4000HWA apart from a basic front-loader is its smart layer. Built-in Wi-Fi connects the machine to the LG ThinQ app, so you can start, pause, and monitor cycles remotely, receive end-of-cycle notifications, and even get maintenance reminders. Compatibility with Amazon Alexa and Google Assistant adds voice control for hands-free convenience.
This washer is best for households that value smart home integration and want serious cleaning power without babysitting the laundry room. If you prefer a no-frills mechanical machine or have a very small living space, the size and feature set may be more than you need.

Performance
In day-to-day use, the WM4000HWA lives up to its high-capacity billing. Large loads of mixed laundry come out clean without needing pre-treatment for everyday soil, and the 6Motion system handles delicate items noticeably more gently than older agitator-style washers. Bulky items such as bedding fit comfortably, which is where the 5.0 cu. ft. drum earns its keep.
The smart side performs better than many connected appliances. The ThinQ app connects quickly, remote start works as advertised, and end-of-cycle alerts are genuinely helpful for avoiding forgotten wet laundry. Voice commands through Alexa and Google Assistant cover the basics reliably, and the AI cycle recommendations become more useful the more you run the machine. If TurboWash speed matters to you, our LG TurboWash 360 review covers the faster sibling model.
Value for money
The WM4000HWA sits in the upper-mid tier of front-load washers. You are paying a premium for the smart connectivity and the large drum, so its value depends on how much you'll actually use those features. For a large household that runs frequent, varied loads and appreciates app and voice control, the convenience justifies the price.
Buyers who want a straightforward washer and won't touch the app may find better value in a simpler, less expensive model — our roundup of the best washing machines under $700 highlights solid alternatives. But as a long-term investment for a connected home, the combination of capacity, efficiency, and smart features makes the WM4000HWA a sensible buy.
Final verdict
The LG Smart Front-Load Washer 5.0 cu. ft. with Wi-Fi and ThinQ (WM4000HWA) earns a solid 8.6/10. It combines a roomy drum, gentle-but-effective washing, and a smart feature set that actually works in practice. For larger families wanting to modernize laundry day, it's well worth buying.
