Features
Ultra Large 4.5 cu. ft. Capacity
Handle bigger loads in fewer cycles with a 4.5 cu. ft. drum that fits bulky bedding, towels, and family-sized laundry with ease, making it a smart fit for busy households.
ThinQ Wi-Fi Smart Control

Allergiene Cycle with Steam Technology
The AAFA-certified Allergiene cycle uses steam to reduce common household allergens from fabrics, offering deeper care for families who need more than a standard wash.
Why You'll Love It
The LG WM3700HVA is a 4.5 cu. ft. smart front load washer designed for households that need serious cleaning power, allergy-safe cycles, and Wi-Fi convenience in a standard 27" laundry footprint. It edges out basic front loaders with proprietary steam, ColdWash, and ThinQ connectivity that simpler models skip.
- A strong fit for busy families: 4.5 cu. ft. of ultra large capacity handles bulky bedding, towels, and heavy-duty loads without multiple runs.
- Allergy-conscious households benefit from the AAFA-certified Allergiene Cycle and Steam Technology that reduce common allergens deep in fabrics.
- ThinQ Wi-Fi lets you monitor cycles, receive notifications, and run SmartDiagnosis from your phone, making it a practical upgrade for tech-forward homes.
- At 27" wide and 39" tall, this washer installs cleanly in standard laundry closets and pairs with the matching DLEX3700W electric or DLGX3701W gas dryer for a coordinated set.
WM3700HVA: Features Built for Real Laundry
The WM3700HVA packs a wide range of LG-exclusive technologies into a 27" cabinet, offering more wash programs, smarter sensing, and quieter operation than entry-level front loaders.
- 4.5 cu. ft. ultra large capacity handles king-size bedding and full-family loads in a single cycle.
- 6Motion Technology uses up to six distinct drum movements per cycle to match wash action to fabric type for thorough, gentle cleaning.
- Steam Technology and the AAFA-certified Allergiene Cycle penetrate fabrics to remove allergens and refresh garments without full washing.
- ColdWash option delivers a warm-water clean performance using cold water, helping reduce energy costs cycle after cycle.
- Inverter Direct Drive Motor carries a 10-year limited warranty; NeveRust Stainless Steel Drum and TrueBalance Anti-Vibration System ensure long-term durability and LoDecibel quiet operation.
- ThinQ Wi-Fi connectivity enables remote start, cycle monitoring, energy tracking, and SmartDiagnosis from a smartphone; ENERGY STAR Most Efficient 2019 certified.
