2-1. FEATURES
Features Description

Smart Control · Samsung's innovative Smart Control technology enables you to control your
washer through personal technologies such as smart phones. You don't have
to be on standby until the cycle ends. Smart Control allows you to monitor the
washing process and let you know when the cycle is complete.

Smart Care · Samsung's Smart Care, an automatic error-monitoring system, detects and
diagnoses problems at an early stage and provides a quick and easy solution
through LCD navigation. With the innovative Smart Control technology, you can
also be alerted when the problem occurs via your smart phones.

Self Clean+ · Clean your drum with one button! This Pure Cycle is specially designed to remove
(Tub Cleaning cycle) detergent residue and dirt buildup in the tub, diaphragm, and on the door glass
without the need for special chemical detergents.

SuperSpeed · Cutyourlaundrytimeinhalfandcleanefficiently.SimplyselectSuperSpeedto
wash a full load in 30 minutes. A powerful water spray helps detergent penetrate
fabrics faster and speeds up rinsing. A larger-diameter drum cleans with more
forceandaSwirl+patternextractswatereffectively.

Bixby · UseyourwashingmachinemoreoptimallyandeasilywiththeBixbyartificial
intelligence (AI) system. `Laundry Recipe' recommends wash cycles, `Laundry
Planner' optimizes your daily schedule, `HomeCare Wizard' enables remote
troubleshooting, and `Auto Cycle Link' ensures optimal drying.

DD Motor · The power to handle anything! Our direct-drive inverter motor delivers power
right to the washer tub from a variable speed, reversible motor. A beltless direct-
drivemotorgeneratesahigherspinspeedof1,300rpmformoreeffective,quiet
operation. The washer also has fewer moving parts, meaning fewer repairs.

Pedestal with Storage · An optional 15" pedestal is available to raise the washer
Drawers for easier loading and unloading.
(Model No : WE357*) Italsooffersabuilt-instoragedrawerthatcanholda
100 oz. bottle of detergent.




Stacking · Samsung washers and dryers can be stacked to
(Model No : SKK-7A) maximize usable space. An optional stacking kit is
available for purchase from your Samsung retailer.
