  • The ENERGY STAR emblem signifies that the Duet washer meets the requirements set forth by the Department of Energy for cleaning efficiency
Ultra Capacity Plus
6th Sense Technology
  • As soon as the wash cycle is started, Duet and Cabrio washers use various sensors to determine the size of the load and precisely how much water is needed to clean it
  • Heat sensors then monitor the temperature, and make sure water is warmed gradually to make cleaning enzymes optimally effective
  • Suds sensors also work to prevent oversudsing in the low water wash system
Direct Inject Wash System
  • A stain-removing shower of concentrated detergent deep cleans large loads and delicate garments, ensuring thorough cleaning
Care Control Temperature Management
  • Care Control Temperature Management uses built-in sensors to monitor wash water and ensure it's warm enough to dissolve detergents and cool enough to ensure proper fabric care
Quiet Wash Plus Noise Reduction
  • Innovative noise reducing technology brings the beauty of silence to the laundry room. Choose a washer with the quiet wash package that meets your needs; Ultra Quiet Wash, Quiet Wash Plus and Quiet Wash
  • All three packages are remarkable for what they don't do - make noise
  • Ultra Quiet Wash: Our quietest wash system ever. Strategically-placed, sound absorbing materials on the front, sides and bottom of the washer cabinet, along with a quieter hose design, gives you the flexibility to operate the washer wherever and whenever
  • Quiet Wash Plus: Sound-absorbing materials on the front, sides and bottom of the cabinet help keep operational sounds inside the washer and out of your daily life
  • Quiet Wash: Helps reduce operational noise with a sound-absorbing pad on the front of the washer cabinet
