What the WM3400CW is and where it fits
The WM3400CW is LG’s straightforward 4.5 cubic foot front loader: no Wi-Fi, no app, no touchscreen, just a machine with hard buttons, touch buttons and LG’s Dial-A-Cycle selector. It is built on the same closet depth chassis LG uses across the range, which the company describes as shallower than a standard front loader so it fits into places a deeper machine cannot. It weighs 187.4 pounds. For a household that wants the cleaning performance and water efficiency of a modern front loader without paying for connected features, this is the model that occupies that position, and LG names its matching dryers directly: the DLE3400W electric and the DLG3401W gas dryer.
Living with it day to day
The cycle list is where the daily character shows. LG publishes eight programs, listed as Normal, Permanent Press, Heavy Duty, Delicates, Towels, Speed Wash, Bedding and Tub Clean, alongside eight options: pre wash, delay wash, ColdWash, extra rinse, rinse and spin, control lock, spin only and signal. Five wash and rinse temperatures run from tap cold through to extra hot, and three soil levels and three spin speeds give further control. That is a comprehensive rather than a minimal control set, and the presence of a dedicated Tub Clean program matters on a front loader, where drum cleaning is a maintenance requirement rather than an optional extra.
Water level is described as load sensing, so the machine decides how much water a load needs rather than filling to a set line, and the SenseClean system is LG’s name for that behavior. TrueBalance is the anti vibration system, which on a front loader matters because spin speeds are high enough to walk an unbalanced machine across a floor. LG publishes no decibel rating in this listing, so noise cannot be quoted from the manufacturer, though a direct drive motor removes the belt that is a common source of noise and of wear on older designs. The four tray dispenser handles pre wash and main wash separately, including liquid detergent. Buyers who want the connected version of a similar machine should compare the LG WM4000HWA.
Controls and connected features
There are no connected features, and that is the defining characteristic of this model rather than an omission. Everything is on the console: hard buttons, touch buttons and a cycle dial. There is no account, no pairing, no firmware and nothing that can be discontinued, which on an appliance LG backs with a 10 year motor warranty is a coherent position. A control lock is included for households with children. What is genuinely lost compared with a connected machine is remote cycle monitoring, push notifications when a load finishes, and the diagnostic reporting that lets a service technician read an error history before arriving. For most households the first two are conveniences and the third is only relevant once.
Running cost and upkeep
This listing publishes the electrical requirement as 120 volts, which is useful and uncommon in this category, though no amperage or circuit specification is given, so the installation manual should still be consulted. There is no gas connection and no venting requirement, because this is a washer with no drying function. Water supply and drain requirements are not published, and both matter for a front load installation. Energy performance is unusually well documented: Energy Star qualified, Energy Star Most Efficient 2019, CEE Tier 2, with an Integrated Modified Energy Factor of 2.92 and an Integrated Water Factor of 2.9. Those two numbers are the industry’s standardized measures and they allow a direct comparison against any other washer that publishes them, which is far more useful than a general efficiency claim.
The 10 year limited warranty applies to the direct drive motor rather than to the whole machine, which is the usual structure and worth understanding: it covers the component least likely to fail rather than the electronics or the door seal. Upkeep is the standard front loader routine, and skipping it is what generates the complaints this class of machine attracts. Run the Tub Clean program on schedule, leave the door ajar between washes, wipe the gasket dry, and rinse the dispenser trays. Two contradictions in the listing need naming. The maximum spin speed is given as 1300 rpm in the description and 700 rpm in the specification table, and those are very different machines in terms of how wet clothes leave the drum, so the figure should be confirmed from LG. The access location field also reads top load on a front loading washer. Stated dimensions of 32 by 30 by 40 inches are inconsistent with a 27 inch wide laundry appliance and look like carton measurements rather than the cabinet. The rest of the range sits in the washers section, including the larger LG WM4200HWA.
Highlights
- Voltage is published at 120 volts, which most laundry listings in this catalog omit.
- IMEF of 2.92 and IWF of 2.9 allow a like for like efficiency comparison with any rival.
- Energy Star Most Efficient 2019 and CEE Tier 2 are both stated.
- Eight programs, eight options, five temperatures and three soil levels give real control.
- Direct drive motor with a 10 year limited warranty and no drive belt.
- Dedicated Tub Clean program, load sensing water levels and TrueBalance anti vibration.
Things To Consider
- Maximum spin speed is given as 1300 rpm in one place and 700 rpm in another.
- The access location field reads top load on a front loading machine.
- Stated dimensions of 32 by 30 by 40 inches do not describe a 27 inch wide washer cabinet.
- The 10 year warranty covers the motor, not the whole appliance.
- Water supply and drain requirements are not published.
- The program list in the description names Speed Wash twice, so the count of eight does not add up.
Who it is not for
Anyone who wants notifications when a load finishes, or remote diagnostics, should buy a connected model, because nothing here can be added later. Households unwilling to run a tub clean cycle and air the gasket should not buy a front loader at all. Buyers who need a washer and dryer in one appliance are in the wrong category entirely, and buyers who need a machine that can be moved between apartments should look at portable units such as the COSTWAY twin tub portable washer, since a 187 pound front loader plumbed to a standpipe is not a machine that moves easily.
