LG WM3400CW 4.5 cu ft
The LG WM3400CW is the cheapest way into a full-size LG front-loader. You get the same 4.5 cu ft drum as LG's $1,100 flagship, LG's 6Motion wash, quiet LoDecibel operation, and 8 cycles that cover everyday laundry. What you give up is everything extra: no Wi-Fi, no steam, and the fewest cycles of any LG in this catalog. At $700 it scores 6.7 - the lowest of any full-size front-loader here. The one decision that matters: whether the $100 step up to the WM3500CW (two more cycles), or a same-priced Samsung with steam, is worth more to you than simply keeping that money.

No Wi-Fi, no steam, and only 8 cycles - the fewest of any LG here.
Full-size front-load: freight delivery, hookups, and permanent installation - no portability.

What the WM3400CW gets right
The capacity is the headline, and it earns a 9. At 4.5 cu ft, this is the same drum size as LG's $1,100 TurboWash 360 flagship - roomy enough for bulky bedding and full family loads, with no compromise on how much laundry you move per cycle. That is the entire argument for buying full-size over a portable. LG's 6Motion wash and LoDecibel quiet operation are both named on the listing, so wash action and noise track the rest of LG's front-load line rather than the entry price. It is a high-efficiency front-loader, which means lower water and energy use per load than a top-load agitator. If your goal is a lot of clean laundry from a quiet, efficient machine wearing an LG badge, the WM3400CW delivers exactly that. The catalog bears it out: capacity is the one dimension where this unit ties the best washers here, flagships included. Everything separating a 6.7 from an 8 lives in the two scores below.
What you give up at this price
Two scores tell the honest story. Features earns a 6, and the reasons are concrete: no Wi-Fi, no steam, and 8 cycles - the fewest of any LG in this catalog. There is no app to start a load from your phone, no steam option for sanitizing or loosening allergens, and fewer specialty programs than the step-up models. For a lot of households, none of that matters. But if you were expecting smart features because it is an LG front-loader, this is the trim level that leaves them out. Practical earns a 5, and that is not a knock on this unit specifically - every full-size front-loader in this catalog scores 5 there. It is a permanent appliance: freight delivery and professional installation apply, you need existing hot and cold hookups and a drain, and it is not going anywhere once it is set. That is simply what a full-size washer is. If either reality is a dealbreaker - no smart features, or nowhere to plumb it in - the WM3400CW is not your machine, and the catalog holds better-matched options.
WM3400CW vs WM3500CW: is $100 worth two cycles?
This is the decision most LG shoppers actually face. The WM3500CW sits one rung up at around $800 and scores 7 overall versus this unit's 6.7. What the extra $100 buys is narrow: 10 cycles instead of 8, which lifts the features score from 6 to 7. Both machines share the identical 4.5 cu ft drum, both are quiet LG front-loaders, and - the part worth sitting with - neither one adds Wi-Fi or steam. So the upgrade is two more wash programs, not a different class of machine. If those two programs map to something you would genuinely use, the WM3500CW is the safer pick, and it is the one most buyers land on. If they do not, the WM3400CW keeps $100 in your pocket for the exact same capacity and wash technology. Be honest with yourself about whether you have ever run out of cycle options on a washer. Plenty of people never touch more than three or four of them. For that person, paying up for cycles nine and ten is spending money to close a gap they will never notice.
The same $800 also buys steam
Here is the wrinkle that complicates the LG-to-LG upgrade. If you are willing to spend $800 - the price of the WM3500CW - the Samsung WF45R6100 costs the same and adds something the 3500 does not: steam. It matches this LG on capacity (4.5 cu ft, a 9) and carries 10 cycles, scores the same 7 overall as the 3500CW, and its steam is genuinely useful for allergy households and sanitizing loads. So lay the money ladder out plainly. At $700 you get the WM3400CW: full capacity, no extras. At $800 you can go two directions - the LG WM3500CW for two more cycles and brand continuity, or the Samsung WF45R6100 for two more cycles plus steam. If steam matters to you at all, the Samsung is the better use of $800 than the mid-tier LG. That does not make the WM3400CW a bad buy - it makes it the right buy only when you specifically do not want to spend the extra $100 in either direction.
Delivery, installation, and the real $700
The sticker is $700, but a full-size front-loader is never just the sticker. The listing notes that freight delivery and installation apply, which is the practical score of 5 in plain terms. You need a laundry space with hot and cold hookups and a drain, and depending on how you buy it, delivery of a heavy appliance and hookup of the water lines can be extra or scheduled separately. Budget for that before you set this $700 machine against a $340 portable that arrives in a box and connects to a sink - they are not the same purchase, and the price gap narrows once installation is counted. None of this is unique to the WM3400CW; it is true of every washer in the full-size group. The point is only this: the entry LG price gets you in the door at the lowest number, but the total to get it washing runs higher than $700. Do that math before you decide the cheapest LG is automatically the cheapest path to clean laundry.
Who it's for / who it's not
Who it's for
- You want LG's full 4.5 cu ft drum and quiet front-load wash at the lowest possible price.
- You do standard laundry - everyday, delicates, bulky - and will never miss the specialty cycles.
- You already have hot and cold hookups and a drain in a dedicated laundry space.
- You do not want Wi-Fi or steam and refuse to pay for features you will not use.
Who it's not for
- You want steam for allergies or sanitizing - the same-priced Samsung WF45R6100 is the better $800.
- You rent or lack laundry hookups - a portable connects to a faucet with no plumbing.
- You are spending $800 anyway - the WM3500CW or Samsung steam model are the stronger buy at that budget.
