A:Answer Hi Laura. The ENERGY STAR® Certified LG 5.0 cu. ft. Mega Capacity Smart Wi-Fi Enabled Front Load Washer with TurboWash™ 360° and Built-In Intelligence, Model # WM4200HWA is designed for use with only HE (High-Efficiency) detergents. That is standard with High-Efficiency washers. HE Detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of the washer clean. Using a detergent that is not HE may cause oversudsing and unsatisfactory performance which could result in error codes, cycle failure, and washer damage. Detergents designated as HE-compatible may not provide optimal results...^Ivan
