Description & Features
The LG WM3400CW front-load washer is designed to give busy households a smarter, more efficient way to tackle laundry day, combining generous capacity with advanced fabric-care technology in a sleek 27-inch-wide footprint. Its ultra-large 5.2 cu. ft. (Canadian) drum lets you wash bigger loads—up to about 20 pounds of laundry at once—so you can cut down on the number of cycles you run each week while still giving clothes plenty of room to move for a thorough clean. At the heart of this model is 6Motion™ Technology, which tailors each cycle using up to six distinct wash motions to lift and remove soil while staying gentle on fabrics, helping your favourite pieces look newer for longer. Paired with ColdWash™ Technology, the washer delivers warm-water cleaning performance while using energy-saving cold water, so you can confidently wash everyday loads and darks without worrying about fading or high utility bills. The ENERGY STAR® certification and “Most Efficient” recognition on many versions of this model underline its low energy and water consumption, making it a smart choice for both the environment and your monthly costs. Another standout feature is Smart Diagnosis™, which allows the washer to communicate key information to customer support if an issue arises, helping reduce unnecessary service visits and getting you back up and running faster. For even more flexibility, the WM3400CW is compatible with the optional LG SideKick® pedestal washer, so you can wash two loads at once—such as delicates or workout gear in the lower mini washer while a large mixed load runs up top—without extending your laundry day. Inside, a durable NeveRust® stainless steel drum resists chipping and snagging, while the TrueBalance™ anti-vibration system helps keep operation quiet and stable, even during high-speed spins. Thoughtful options like Delay Wash, Extra Rinse, Tub Clean, and a child lock give you added control over every cycle. With its combination of ultra-large capacity, energy-saving cold-water performance, multi-motion wash action, and smart service support, the LG WM3400CW offers a feature set that stands out from many standard front-load washers in its class.

5.2 cu. ft. Ultra Large Capacity (IEC, Canada) – handles big loads and bulky items so you can wash more laundry in fewer cycles.

ENERGY STAR® Certified & ENERGY STAR® Most Efficient – reduces water and energy use to help lower utility bills while meeting strict efficiency standards.

6Motion™ Technology – uses up to six different wash motions (tumbling, rolling, scrubbing, etc.) for a deeper yet gentle clean on a wide range of fabrics.

ColdWash™ Technology – delivers warm‑water cleaning performance using cold water, helping protect fabrics and colours while saving energy.

Inverter Direct Drive™ Motor – motor is directly attached to the drum for improved efficiency, fewer moving parts, and enhanced durability.

Direct Drive Motor 10‑Year Limited Warranty – long motor warranty coverage for added peace of mind on a key component.

SmartDiagnosis™ – lets the washer communicate diagnostic data to LG customer service to help quickly troubleshoot issues.

TrueBalance® Anti‑Vibration System – minimizes vibration and noise, making it suitable for main‑floor or near‑living‑space installations.

Stackable Configuration – can be stacked with the matching LG dryer using an optional stacking kit to save floor space.

Matching LG Dryer Options – pairs with LG DLE3400W electric dryer or DLG3401W gas dryer for a coordinated laundry set.

Ultra Large Door Opening with Clear Round Cover – wide, see‑through door makes loading bulky items easier and lets you monitor the wash.

4‑Tray Detergent Dispenser – separate compartments for prewash, main wash (with liquid detergent cup), bleach, and fabric softener for proper dispensing.

LoadSense Automatic Water Level – adjusts water usage based on load size to improve cleaning efficiency and reduce waste.

Maximum 1300 RPM Spin Speed – high‑speed spin extracts more water to shorten drying times and improve energy savings.

8 Preset Wash Cycles – includes Normal, Heavy Duty, Perm Press, Delicates, Towels, Speed Wash, Bedding, and Tub Clean to cover everyday and specialty loads.

Speed Wash Cycle – quickly cleans small, lightly soiled loads when you need clothes in a hurry.

Bedding Cycle – optimized for bulky items like comforters and duvets to improve cleaning and rinsing.

Towels Cycle – tailored for thicker fabrics to help remove soil and detergent thoroughly.

8 Wash Options – includes ColdWash, Extra Rinse, Prewash, Rinse+Spin, Spin Only, Delay Wash, Signal, and Control Lock for added flexibility.

5 Wash/Rinse Temperature Settings – offers Extra Hot, Hot, Warm, Cold, and Tap Cold to match fabric care labels and soil levels.

5 Spin Speed Settings – adjustable spin (High, Medium, Low, plus lower settings) to balance moisture removal with fabric care.

3 Soil Level Settings – lets you choose soil intensity so the washer can adjust cycle time and action accordingly.

Child Lock / Control Lock function – disables controls during operation to prevent accidental changes by children or pets.

Delay Wash option – allows you to schedule the start of a cycle for a later time to fit your routine or off‑peak utility rates.

Extra Rinse option – adds an additional rinse to help remove detergent residue, ideal for sensitive skin or heavily soiled loads.

Prewash option – provides an initial wash phase for heavily soiled items before the main wash.

Rinse+Spin option – quickly rinses and spins items that need freshening without a full wash cycle.

Spin Only option – runs a spin cycle alone to remove excess water from hand‑washed or previously washed items.

End‑of‑Cycle Signal – audible alert notifies you when the cycle is complete so clothes can be removed promptly.

Auto Suds Removal – automatically removes excess suds to maintain optimal washing performance and protect the machine.

4 Adjustable Leveling Legs – allow precise leveling of the washer to reduce vibration and improve stability.

White Cabinet Finish – clean, neutral exterior colour coordinates easily with most laundry room designs.

120V / 10A Power Requirement – plugs into a standard household outlet for straightforward installation.

Stainless Steel Wash Basket – durable interior resists staining and odours better than plastic tubs.
