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+
(Tub Cleaning cycle)
• Clean your drum with one button! This Pure Cycle is specially designed to remove
detergent residue and dirt buildup in the tub, diaphragm, and on the door glass
without the need for special chemical detergents.
SuperSpeed • Cutyourlaundrytimeinhalfandcleane󰀩ciently.SimplyselectSuperSpeedto
