Centrifusion Wash
The locked infusor and wash basket begin a
clockwise spin (figure 1). The speed of the spin is
customized to the load type and fabric type. As
the basket spins faster, it creates a strong flow of
water under the centrifugal force (figure 2).
As water passes through the fabric, its natural
cleansing action washes away dirt without
damaging or tangling the fabric.
Fabric
Water
Current
After several seconds of clockwise spinning, the
basket slows down and stops. The wash water
pools back into the wash basket. The wash
basket starts spinning in the counterclockwise
direction creating the same cleaning action. The
washer will change direction (up to four times)
before going to the next cycle.
Infusor Wash
Following the centrifusion wash cycle, the basket
and infusor unlock. The infusor rotates to evenly
distribute the wash load while continuing to clean.
The redistribution of fabrics helps ensure that the
lint and dirt do not become trapped.
Spin
The infusor and wash basket lock together. The
basket spins very slowly at first. This allows dirty
wash water and lint to drain through the holes in
the bottom of the basket before a higher spin
begins. When the washer senses that the excess
water has drained, the wash basket accelerates
to a higher speed.
Spin speeds are adaptive to fabric type that is
selected by the user on the LCD touch screen.
They can be as slow as 350 rpm for hand-wash
items and up to 1010 rpm for heavier items. The
spin is designed to extract as much water and
detergent as possible without harming fabrics.
Note: During the spin cycle, excessive suds can
cause excessive torque on the motor. If the
washer detects this condition, it will run through
the rinse, drain, and spin cycle (up to three times)
in an attempt to eliminate the suds
Note: The washer is programmed to correct out
Soil
of balance situations during spins. If the washer
senses an out of balance load, the spin is
stopped. The washer then refills to allow the
infusor wash cycle to redistribute the load before
starting the spin again. The washer attempts to
rebalance the load three times before optimizing
the spin to a lower speed where balance is
sustainable.
Spray Rinse
The infusor and wash basket turn at a slow speed
while fresh, clean water is added to the wash
load. The spin cycle then drains this rinse water
and prepares the wash load for a final rinse.
Final Rinse
The washer retrieves the information it gathered
for adaptive fill cycle and uses that information to
refill the washer for the final rinse. Cold water
enters the basket through the fabric softener
dispenser to dilute the softener into the basket
and rinse the dispenser clean. The wash basket
fills to the optimal level and goes into a basket
wash cycle where the clothes and fabric softener
are mixed thoroughly. A final spin finishes the
cycle.
Note: All rinse cycles use cold water and the
(ATC) automatic temperature control is not used.
The cold rinse is the same temperature as the
incoming cold water supply.
