Ben's Appliances and Junk runs what might be the most rigorous appliance testing on YouTube. He buys Swiss EMPA 135 stain strips at $25 each, washes them in every machine he tests, then measures the remaining stain color with a spectrometer. He also aggregates polls from hundreds of repair technicians alongside over a million consumer reviews. The LG WM4000HWA sits at the top of that composite ranking.
Pro Picks confirmed the result from a different angle. They tested TurboWash 360 and found it cleaned a full load in under 30 minutes using five high-pressure jets that hit clothes from every direction. That's a real cycle with real results, not a quick rinse that leaves half the stains behind. The same review praised the AI Fabric Sensor for auto-detecting fabric type and load size, adjusting wash motions and temperature without you touching a dial.
Energy efficiency sealed the pick. Pro Picks measured the WM4000HWA as one of the most efficient machines in their entire testing lineup. A front-loader that cleans faster than most, uses less water and electricity, and does it with a 4.5 cu ft drum large enough for a family of four. At $898, it costs less than the Electrolux ELFW7637AT while matching it on cleaning and beating it on cycle speed.
Ben's teardown confirmed the internals match the reputation. LG's direct-drive motor eliminates the belt and pulley system that wears out in cheaper machines. Fewer moving parts means fewer things to break.
What It Won't Do
Front-loaders demand maintenance that top-loaders don't. You need to wipe the rubber door gasket after every load and leave the door cracked open to dry. Skip this routine and you'll grow mold inside the seal. Ben's Appliances warned that neglected gaskets lead to expensive rear bearing failures. The ThinQ app also lags when you try to start cycles remotely, and the display's cycle time estimates become fiction the moment you add extra rinses or steam.
Ben's Appliances performed the teardown that makes this pick click. He pulled apart the LG WT6105CW and found the same direct-drive stator and shift actuating system that powers LG's $900+ premium top-loaders. Same motor. Same transmission. Same internal architecture. His exact words: buying this $500 model 'makes a lot more sense' than spending double for the same core technology.
HTECK and Valid Consumer tested the Turbo Drum system independently. The drum and pulsator rotate in opposite directions, creating a four-way wash action that cleans without tangling clothes into a knotted ball. HTECK also measured lower water and energy consumption compared to traditional agitator machines, which matters when you're running five loads a week.
The real value proposition is what you don't pay for. No rubber gasket to maintain. No mold risk. No bending down to load and unload. Glass lid lets you watch the cycle and toss in a forgotten sock mid-wash. These aren't features, they're the absence of problems that front-loader owners live with every day.
At $498, you're paying budget prices for flagship-tier mechanical reliability. The WT6105CW won't clean stains as deeply as the WM4000HWA, and the spin cycle won't extract as much water. Those are real tradeoffs. The question is whether the $400 savings and zero-maintenance convenience outweigh them.
What It Won't Do
The 4.1 cu ft drum is the ceiling. Valid Consumer tested it with king-sized bedding and it came up short, the comforter couldn't move freely enough to get clean. HTECK found the default water level too conservative for large loads, forcing you to manually override with Deep Wash every time you stuff the drum. And the spin cycle sometimes leaves clothes wetter than expected, adding 10-15 minutes to your dryer time.
Who Should Buy Which
LG WM4000HWA
The machine repair technicians vote for when asked to pick the single best washer on the market
- Families of 3-5 who run 4+ loads weekly and want the machine that repair technicians themselves recommend
- Stain fighters who need 30-minute TurboWash cycles that actually clean, not quick rinses that skip stains
- Energy-conscious buyers who want the lowest water and electricity costs per load
- Tech-forward households that use app-controlled cycles, AI fabric sensing, and smart dryer pairing
- Buyers willing to maintain a front-loader (wipe gasket, crack door open) in exchange for superior cleaning
LG WT6105CW
Flagship-grade direct-drive motor hidden inside a $500 top-loader
- Budget shoppers who want LG's proven direct-drive motor at half the price of premium models
- Renters or first-time buyers who need reliable washing without a $900 investment
- Anyone who refuses to deal with front-loader maintenance, no gasket wiping, no mold worry, no bending
- Smaller households (1-3 people) where the 4.1 cu ft drum handles weekly loads without issue
- Buyers who prefer simple, mechanical reliability over smart features and app integration
