Quick Review

The LG SIGNATURE WM9900HSA washing machine is what happens when LG throws every technology it has at a single front-load washer and gives it that memorable LG signature design that is both minimalistic and highly functional. My kids call it the Cybertruck of washing machines, and while that might sound controversial, they do have a point. The 5.8-cubic-foot drum is the largest you’ll find in a front loader this side of a laundromat. The 7-inch LCD display replaces the usual buttons and dials, while the ezDispense system means you can go weeks without touching a detergent bottle. After running it through weeks of real family laundry (including a highly OCD daughter who washes her towels after one use), the LG Signature washing machine washes as well as it looks and looks better than 99% of the washing machines on the market. 

That said, $1,899 (as of July 3, 2026, down from a $2,499 list price) is serious money for a washing machine, and the WM9900HSA has a few rough edges that keep it from perfection. The gorgeous touchscreen washes out in direct sunlight, the ezDispense drawer sits low enough to catch a stray foot or laundry basket and feels more delicate than the rest of the machine, and LG’s remote-start implementation is so cautious that it’s effectively useless. None of those are dealbreakers. All of them are things you should know before spending this much.

If you want the biggest capacity, the best screen, and the most hands-off detergent experience in a front-loader (and your budget stretches this far) the WM9900HSA is an easy machine to recommend. If you just want clean clothes, LG’s own WM6700HBA does 90% of this for roughly half the price.

LG SIGNATURE WM9900HSA: Design and build

Most washers are appliances, but this one feels almost like furniture to me. The WM9900HSA’s brushed platinum steel cabinet, tempered-glass door with chrome rim, and nearly button-free fascia give it a presence that justifies the SIGNATURE badge.  It’s the first thing everyone comments on, and weeks in, I still love looking at it. The drum is LG’s NeveRust stainless steel, lit by an interior drum light, and the whole machine is anchored by an inverter direct-drive motor that LG backs for 10 years.

Instead of a typical dial and small display, there is a larger 7-inch LCD touchscreen. It’s fairly responsive to use, but can be laggy when swiping sometimes. Every cycle, temperature, spin speed, and soil level is a couple of taps away, and you can edit the cycle list so your favorites live up front. One real-world caveat: if your laundry area gets direct sunlight, the screen can be hard to read at certain times of day. In a windowless laundry room, this will never bother you; next to my bright window, it occasionally did for me.

My one genuine design complaint is the ezDispense drawer. Its low position on the fascia makes it easy to bump with a laundry basket or your foot, and the drawer mechanism feels noticeably more fragile than the rest of this otherwise tank-like machine. I never broke it, but I was always aware I could.

At 29 inches wide, the WM9900HSA is 2 inches wider than a standard 27-inch washer, so make sure to measure your space and your doorways before ordering. It’s compatible with LG’s WDP8S pedestal, the SideKick pedestal washer (WD405CS) for smaller loads, and can be stacked with the matching dryer using LG’s stacking kit.

LG SIGNATURE WM9900HSA: Installation and setup

This is a 217-pound, 29-inch-wide appliance, so plan on two people at minimum, and professional installation is recommended if you’re unfamiliar with plumbing hookups. Full disclosure, though. LG provided installation through their concierge service for me, so I did not have to hook this up myself.  Requirements are otherwise standard front-loader fare: hot and cold water connections, a drain standpipe, and a regular 120V outlet.

Once it was in place and leveled, software setup took around 10 minutesminutes. The washer connects to Wi-Fi through LG’s ThinQ app, which walks you through registration, and the touchscreen makes initial configuration far less painful than punching through seven-segment displays on a typical washer. Filling the ezDispense reservoirs, one for HE detergent, one for fabric softener, is the last step, and depending on load sizes, a single fill lasts LG’s claimed 20 to 36 loads. That claim held up in my experience; I went weeks between refills. I prefer to use fabric softener sheets, so instead of loading the second dispenser with fabric softener, I filled it with detergent. 

Wash performance

Cleaning performance is what you’d hope for at this price and was consistently excellent for me. The big claim-to-fame technology is TurboWash 360, which uses multidirectional spray jets to cut Normal-cycle times to under 30 minutes for full loads without a noticeable drop in cleaning quality. Combined with AI Wash (LG’s built-in intelligence that senses load size and fabric type, then adjusts wash motions and settings automatically), the WM9900HSA seemed to handle everything without me having to tweak things.

The 5.8-cubic-foot drum is great for large loads. King-size comforters, a full week of towels for a family, washable rugs, and things that required a laundromat trip or two separate loads on our previous washer fit in a single cycle here with room to tumble. For big households, the capacity alone can help free up your time on your Sunday afternoon.

What impressed me most day-to-day is the customization. All 26 cycles, including Allergiene (a steam-based allergen cycle), Sanitary, Bright Whites, Sweat Stains, Jeans, and an Overnight Wash, can be tweaked for temperature, spin speed, soil level, and extras like Extra Rinse or Prewash, and the machine remembers your adjustments. It’s the rare appliance that rewards both the set-it-and-forget-it user and the tinkerer. My daughter loves using all of the custom settings, but I usually stick with Normal and Delicate settings for my laundry loads.

Cycle options and specialty features

The ezDispense system deserves its own section because it changes the daily experience of doing laundry more than any single feature. Fill the reservoirs, and the washer meters the right amount of detergent and softener for every load based on size and soil level. No measuring, no drips, no blue crust on the dispenser drawer. It’s effortless in the way good luxury features are. 

You stop thinking about it entirely, and it genuinely feels like a premium touch every time you skip the detergent bottle. It works with standard HE liquid detergent, and you can still add pods or powder manually for individual loads if you prefer. To be fair, this is not a feature that is uncommon, and you can find auto-dispenser features on lower-priced washing machines. But if you are coming from an older machine, you really are in for a treat. 

Steam is built in and powers the Allergiene and Sanitary cycles; five wash/rinse temperatures run from tap cold to extra hot. There’s also ColdWash for energy-conscious washing or those afraid that their clothing will shrink, a Tub Clean cycle with a built-in coaching feature that reminds you when it’s due, and an ezDispense nozzle-clean routine to keep the auto-dispenser itself fresh. Tub Clean is recommended every 30 washes and takes about 2.5 hours to do each time.

Noise and vibration

LG’s True Balance anti-vibration system and the direct-drive motor keep the WM9900HSA impressively quiet. Wash phases are conversation-quiet, and even at the 1,300-RPM maximum spin, the machine stays planted without walking or drumming. [TK: dBA measurements during wash and max spin; need to put numbers in here]

Water and energy efficiency

The WM9900HSA is ENERGY STAR certified, carries the ENERGY STAR Most Efficient designation, and sits in the CEE Advanced Tier, which is the top rung of the Consortium for Energy Efficiency’s rating. Its Integrated Modified Energy Factor (IMEF) of 3.2 and Integrated Water Factor (IWF) of 2.6 put it among the most efficient large-capacity front-loaders you can buy, per Energy Star’s DOE-based test methodology. The ThinQ app also includes energy monitoring, so you can see actual consumption per cycle rather than relying on estimates. No clue how many people will actually use this feature, and it certainly is not important to me.

LG SIGNATURE WM9900HSA: WM9900HSASmart features and the ThinQ app

This is where the WM9900HSA is both at its best and its most frustrating.

First, the good:  The ThinQ app lets you power on the washer, start and monitor cycles, and change settings remotely, and every one of those functions worked reliably for me. Push notifications when a cycle finishes are prompt and genuinely useful when the laundry room is out of earshot. You can build smart routines, download new and seasonal cycles, and the washer transfers load information directly to the matching DLEX9900S dryer, which then pre-selects the appropriate drying cycle so you literally just hit run.

Google Assistant and Amazon Alexa are both supported, and SmartDiagnosis can flag issues before they become service calls. I did not test Alexa integration or Google Assistant, but will update the review down the road if I get a chance to try these features. 

Now the frustrating part: remote start is pretty much useless as implemented. For safety reasons, you must physically enable Remote Start on the machine itself before the app can start a cycle every single time. If you’re already standing at the washer to press that button, you may as well press Start. I understand the liability logic, but competitors handle this with a persistent opt-in, and LG’s approach reduces an advertised feature to a checkbox on a spec sheet.

How I tested

I used the WM9900HSA as my household’s only washer for size-months running loads across cotton and linens, synthetics, delicates, towels, and king-size bedding, and heavily soiled kids’ and athletic clothes. Cycles tested included Normal, Heavy Duty, Delicates, Quick Wash, Sanitary, and Allergiene. Detergent was [TK: brand] HE liquid dispensed via ezDispense, verified over multiple loads for dosing accuracy. The unit was paired with LG’s matching DLEX9900S dryer, reviewed separately. The unit was provided and installed by LG. 

Comparison and alternatives

The WM9900HSA’s closest in-house rival is LG’s own WM6700HBA, a 5.0-cubic-foot front-loader with TurboWash 360 and ezDispense that typically sells for around half the price but lacks the touchscreen, the SIGNATURE finish, and 0.8 cubic feet of drum, but washes nearly as well. Samsung’s Bespoke WF53BB8900 (5.3 cu. ft.) counters with AI OptiWash and its own auto-dispense system at a lower typical street price, though Samsung trails LG in service-network reliability. And if pure cleaning performance per dollar is the goal, the Electrolux ELFW7637AT (4.5 cu. ft.) remains the most popular for far less money; you just give up capacity and the smart-home polish. 

Should you buy the LG SIGNATURE WM9900HSA?

The LG SIGNATURE WM9900HSA is the best-looking, best-equipped front-load washer LG makes, and after months of daily use, most of its luxury features earn their keep, and I didn’t feel like they were too gimmicky. The app made sure everything was up to date and offered new features like updated smart routines or music on a regular basis, which made me feel like LG was actively involved in making sure the user experience is a priority. 

It loses points for a screen that fights sunlight, a dispenser drawer that feels fragile in a machine that otherwise feels indestructible, and a remote-start feature that’s remote in name only. At $1,899, it’s a splurge. At its $2,499 list price, it’s a hard sell against LG’s own lineup. But if you’re building a premium laundry room and want the full flagship experience, this is the front-loader to beat.

Overall Score: 8.5/10

FAQs

Is 5.8 cubic feet bigger than I need? For singles or couples, honestly, yes. A 4.5 cu. ft. machine will do. For families of four or more, or anyone who washes king-size bedding and comforters at home, the extra capacity pays for itself in fewer loads.

Will it fit where my old washer was? Maybe not. At 29 inches wide, it’s 2 inches wider than a standard 27-inch washer, and it needs about 54 inches of clearance with the door open. Measure your alcove and doorways first.

How do I prevent mold and odors in a front-loader? Leave the door and dispenser drawer ajar between loads, wipe the door gasket dry after washing, use only HE detergent in correct doses (ezDispense handles this automatically), and run the Tub Clean cycle when the washer’s Tub Clean Coach prompts you roughly monthly. I like to use a long magnet rubber arm that sticks to the side of my washing machine and holds the door open.

Does ezDispense require special detergent? No. Any HE liquid detergent and liquid fabric softener work. One fill covers roughly 20 to 36 loads depending on load size and soil settings.

Can I stack it with the dryer? Yes. The WM9900HSA supports the matching DLEX9900S (electric) or DLGX9901S (gas) dryer with LG’s stacking kit, or you can add the WDP8S pedestal or SideKick pedestal washer underneath.
