The short version
LG has been building front-load washers long enough to get the fundamentals right, and the WM4000HBA reflects that experience. The 4.5 cubic foot drum handles large loads well, the Wi-Fi connectivity through the ThinQ app works reliably, and the Black Steel finish stands out from the standard white appliances that dominate most laundry rooms.
What puts this model in top-pick territory is the combination of genuine smart features, strong wash performance, and a price point that competes well against comparable machines from Samsung and GE.

Performance in real use
Wash performance is excellent across all load types. Heavy cycles handle bulky items like comforters and towels thoroughly. The 1300 RPM spin speed extracts significant moisture, which shortens dry times and reduces energy use in the dryer.
Steam function is genuinely useful for sanitizing and reducing wrinkles on delicates. It is not a replacement for dry cleaning but handles most at-home fabric care needs well.
The ThinQ app gives you remote start, cycle monitoring, and error notification. In practice the most-used feature is starting a load remotely while you are doing something else in the house. The app setup is straightforward and does not require the patience that some Samsung app setups demand.

How it scores
Our verdict
One of the best front-load washers at this price point
The LG WM4000HBA earns its high rating through consistent performance and reliable smart features. LG's ThinQ platform is more user-friendly than most competing apps, the 1300 RPM spin is among the best in class, and the Black Steel finish holds up well in daily use.
For households building a smart laundry setup, this pairs naturally with LG's matching dryers. For everyone else, it competes strongly on its own merits against the Samsung and GE alternatives in this category.
