LG SIGNATURE WM9900HSA Review: Stylish and Fun Washer

Quick Overview

The LG SIGNATURE WM9900HSA is the result of LG pouring every available technology into a sleek front-load washer, combined with their signature minimalistic yet highly functional design. My kids refer to it as the Cybertruck of washers, and while that may be a bit much, it highlights its bold, futuristic aesthetic. Its 5.8-cubic-foot drum is the largest you’ll find outside of commercial laundromats. The 7-inch LCD touchscreen replaces traditional buttons, and the ezDispense system means you can go weeks without touching a detergent bottle. After testing it with the everyday laundry of my family—including towels, delicate fabrics, and heavily soiled sports clothes—the washer performs as impressively as it looks, surpassing most in the market.

However, with a current price of $1,899 (as of July 3, 2026), down from $2,499, this is a significant investment. The touchscreen can be difficult to read in direct sunlight, the dispensing drawer’s low placement risks accidental bumps, and LG’s remote start implementation is overly cautious, making it practically useless. These aren’t dealbreakers but are important considerations before making such a purchase.

If you desire maximum capacity, an advanced display, and a highly automated detergent system and your budget allows, the WM9900HSA is an excellent choice. Otherwise, LG’s WM6700HBA offers much of this performance at about half the price.

Design and Construction

This appliance commands attention with its brushed platinum steel housing, tempered-glass door with chrome rim, and nearly buttonless interface—making it feel more like a piece of modern furniture. It’s the first thing people notice, and even after months of use, I never tire of its striking appearance. The drum is crafted from LG’s NeveRust stainless steel, illuminated by an interior light, and powered by a 10-year-inverter direct-drive motor, backed by LG’s warranty.

The interface is dominated by a 7-inch LCD touchscreen instead of traditional dials and small displays. It’s responsive, though sometimes a bit slow when swiping. Every cycle parameter, including temperature, spin speed, and soil level, is accessible within a few taps. You can customize your favorite cycles for quick access. A notable drawback is that in bright sunlight, the screen can be hard to see. For dark or windowless laundry rooms, this isn’t an issue; in bright environments, it can be challenging.

Overall, the design feels robust and luxurious. The build quality is evident in every touchpoint, from the sturdy cabinetry to the smooth finish. Despite the advanced technology, the machine’s aesthetic remains clean and uncluttered, fitting seamlessly into a premium laundry space.

My only real design critique revolves around the ezDispense drawer. Its low placement can lead to accidental bumps, and its fragile feel contrasts with the otherwise heavy-duty construction. While I never damaged it, caution is advised during loading and unloading.

Measuring 29 inches wide, it exceeds the standard 27-inch width, so verifying available space beforehand is essential. It’s compatible with LG’s WDP8S pedestal, the SideKick mini washer, and can be stacked with the matching dryer using LG’s stacking kit.

Installation and Setup

At 217 pounds and 29 inches in width, this is a sizable unit. Installation is best handled by professionals, especially if you’re unfamiliar with plumbing connections—LG offers a concierge service to assist with setup, which I used. The typical setup involves connecting hot and cold water lines, a drain pipe, and a standard 120V outlet.

Once installed and leveled, configuring the washer takes roughly 10 minutes. It connects to Wi-Fi via LG’s ThinQ app, guiding you through registration. The touchscreen makes initial setup straightforward, allowing you to customize cycle preferences. Filling the ezDispense reservoirs for detergent and softener is simple; a single fill suffices for roughly 20 to 36 loads, depending on load size and soil level. During my testing, I went weeks without refilling, and I prefer using fabric softener sheets, which I added manually instead of the softener dispenser.

Cleaning Performance

Performing at the high end of expectations for its price point, this washer consistently delivers excellent cleaning results. TurboWash 360, LG’s multidirectional spray technology, reduces full-cycle times to under 30 minutes without sacrificing cleaning quality. AI Wash, an intelligent system that automatically adjusts settings based on load size and fabric type, proved reliable in my experience, handling all kinds of loads seamlessly.

The large 5.8-cubic-foot drum accommodates sizeable items like king-size comforters, multiple towels, and bulky rugs in a single cycle, saving time for large households. The capacity alone can free up weekends typically spent on laundry chores.

Overall, this washer handles dirty loads with ease, maintaining consistent cleaning performance. Its efficiency features help minimize water and energy consumption, making it environmentally friendly without compromising results.

Smart Features and the ThinQ App

The ThinQ app allows remote control, cycle monitoring, and setting adjustments, all reliably functioning during my use. Notifications alert you when a cycle completes, which is especially helpful if the laundry area isn’t visible from your main living space. You can create routines, download new cycle options, and the washer can communicate with the matching dryer to pre-select drying settings based on the load information. Compatibility with Google Assistant and Amazon Alexa is supported, though I haven’t had a chance to test these integrations. The app feels actively maintained, with regular updates adding features like new routines and music options.

The biggest frustration lies in the remote start function. Due to safety concerns, you must manually enable Remote Start on the washer before the app can initiate a cycle. If you’re already standing at the machine, it’s quicker just to press start directly. LG’s approach simplifies liability but diminishes the feature’s convenience, leaving it less useful than advertised.

Testing Methodology

I used this washer as my household’s primary laundry machine for several months, testing various loads—including cottons, synthetics, delicates, towels, king-size bedding, and heavily soiled sportswear. I examined cycle options such as Normal, Heavy Duty, Delicates, Quick Wash, Sanitary, and Allergiene, verifying ezDispense accuracy over multiple loads. The machine was paired with the LG DLEX9900S dryer, and LG handled the installation for me—standard plumbing and electrical requirements apply.

Comparable Alternatives

LG’s own WM6700HBA, with a 5.0-cubic-foot capacity and TurboWash 360, offers much of the same functionality at roughly half the cost but lacks the SIGNATURE finish and extra drum space. Samsung’s Bespoke WF53BB8900 (5.3 cu. ft.) adds AI OptiWash and auto-dispense but trails LG in network reliability. Electrolux’s ELFW7637AT (4.5 cu. ft.) remains popular for cleaning performance at a significantly lower price—though it sacrifices capacity and smart features.

Is the LG SIGNATURE WM9900HSA Right for You?

At $1,899, it’s a premium investment. The design, features, and performance justify the cost for those who want a state-of-the-art laundry setup and have the space to accommodate its size. Its smart capabilities and large capacity make it ideal for big households and tech enthusiasts. However, its sunlight-sensitive display, fragile dispenser drawer, and cautious remote start may be dealbreakers for some. For those seeking a high-end, feature-rich front-loader with an exceptional aesthetic, the WM9900HSA stands out as the top contender.

Overall Score: 8.5/10

Frequently Asked Questions

Is 5.8 cubic feet larger than I need? For singles or couples, probably yes. A 4.5 cu. ft. machine would suffice. For larger families or those washing king-sized bedding regularly, the extra capacity reduces the number of loads.

Will it fit in my space? With a width of 29 inches, it’s 2 inches wider than a standard 27-inch washer. Ensure your space and doorways can accommodate this size before purchasing.

How do I prevent mold and odors? Leave the door and dispenser slightly open between loads, dry the door gasket after washing, use only HE detergents with correct dosing (ezDispense manages this automatically), and periodically run the Tub Clean cycle when prompted. Using a magnet on the door to keep it ajar can also help prevent buildup.

Does ezDispense require special detergent? No, any HE liquid detergent or fabric softener works. One refill can last between 20 to 36 loads, depending on load size and soil level.

Can it be stacked with the dryer? Yes, it supports LG’s matching DLEX9900S (electric) or DLGX9901S (gas) dryers using the appropriate stacking kit, or you can place it on a compatible pedestal.
