NEW COMPONENTS
Sleek Under Glass User Interface — the Whirlpool washer features a new sleek under glass capacive touch user interface
that asks “what’s being washed” followed by “how you want to wash.” First select a cycle from the “What to Wash” (Mixed,
Whites, Casuals, Jeans, Towels, Delicates, AcveWear, and Bulky Sheets) and then select the “How to Wash” (Normal, ColorLast,
HeavyDuty, Oxi Sanize, Deep Water, Cold Wash, and Quick). This new and improved input will help the customer achieve the
best combinaon cycle available for the type of items being washed.

INTRODUCTION
The new Whirlpool & Maytag Direct Drive, Top Load Washer
represents industry-leading innovaon with the new improved
direct drive system. The p revious generaon direct drive
washer operated using a oang basket to assist in the
switching between spin and agitate modes. The
new washer
operates with a clutch coil system that provides reliable,
immediate, and smooth shiing between the various wash
modes.
Basket — the Whirlpool & Maytag washer has an extra
large basket capacity of 6.2 cu.. Other than size, the major
dierence from the previous model is that this basket does not
have a otaon chamber to assist with changing between spin
and agitate modes.
Figure 2 - Basket
Motor — The motor is an electronically commutated direct-
drive 3-phase BPM (Brushless Permanent Magnet) variable
speed design that moves the impeller and spins the basket
without the use of a transmission. The motor is comprised of
a stator and rotor that are aached to the drive assembly. The
motor direcon and speed is controlled by the ACU (Appliance
Control Unit) or main control.

GENERAL INFORMATION
General Theory of Operation (continued)
NEW COMPONENTS (Continued)
Clutch Coil and Clutch Assembly — the clutch coil on
the washer is a simple electromagnec coil, which when
energized, pulls the clutch into contact with the rotor. The
drive assembly contains an internal and external drive sha.
The internal sha, which is connected directly to the rotor,
agitates the impeller; whereas the external sha, which is
directly connected to the clutch, is able to spin the basket.
Therefore, when the clutch coil is energized, the resulng
magnec eld pulls the clutch out to engage with the rotor,
resulng in spinning both the basket and impeller together.
When the coil is de-energized, the clutch disengages the rotor
and the spring returns the clutch to its home posion. The
motor now controls only the impeller.
