DSM is used to better control energy usage throughout the home.9

Rear view of washerFeature Definitions - eWash

eWash - Reduces the total energy consumption by adjusting certain cycle settings.

eWash is a user selectable option that will modify the current cycle settings to reduce the energy used by the machine. eWash is toggled on and off by pressing the eWash button. When eWash is selected, the cycle settings will change to the most energy efficiency settings.10Feature Definitions - eMonitor

eMonitor - Visual display of the energy use of the appliance. eMonitor Ranges:Good (1 light) to Best (5 lights).

11Feature Definitions Overnight Dry

12Overnight Dry is an option that is available on the following cycles: Active Wear, Whites, Normal and Single Item.

Overnight Dry is intended for smaller loads only. This feature is intended for use when clothes need to be washed, dried and ready to wear or finished the next morning.

This feature will tumble clothes and introduce a constant stream of air into the machine compartment upon completion of selected wash cycles.Feature Definitions Power Rinse(1)13The washer uses a recirculation pump to improve rinse performance. This is not a user selectable feature.When Power Rinse is selected the recirculation pump will be activated and spray water on top of the clothes in the washer.

The recirculation pump can operate during Tumble and Fill cycles.

Recirculating PumpRecirculating HoseFeature Definitions Power Rinse(2)14Cycles that have the recirculation pump enabled will turn on the tub Light at the start of the cycle. - The user can turn off the tub light after it is turned on due to recirculation. - At the completion of the cycle the tub light will be turned off.

The recirculation pump will be on for the Duration of a Fill or Tumble cycle.

There must be a minimum water level in the tub in order to turn on the recirculation pump.

Feature Definitions AVC(1)Adaptive Vibration Control15Using information about the floor, this system can reduce vibration and improve spin performance in some installations by adapting the spin cycle.

The DEFAULT configuration is specially designed to provide optimal performance across the widest range of floor types.

Following the procedure in the Use & Care manual, enables more specific adaptive settings.

The washer can be returned quickly and easily to the DEFAULT configuration at any time using the same procedure.Feature Definitions AVC(2)Adaptive Vibration Control16Floor Type Selection1. Place control in the idle state. 2. Press and hold the Power and Spin buttons at the same time for 3 seconds.3. Only the Power, Start and display lights will be lit in this mode.4.
