Centrifusion Wash
The locked infusor and wash basket begin a
clockwise spin (fi gure 1). The speed of the spin is
customized to the load type and fabric type. As the
basket spins faster, it creates a strong fl ow of water
under the centrifugal force (fi gure 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 fi rst. 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.
Soil
Note: The washer is programmed to correct out of
balance situations during spins. If the washer senses
an out of balance load, the spin is stopped. The
washer then refi lls 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 fi nal rinse.
Final Rinse
The washer retrieves the information it gathered
for adaptive fi ll cycle and uses that information to
refi ll the washer for the fi nal 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 fi lls to the optimal
level and goes into a basket wash cycle where the
clothes and fabric softener are mixed thoroughly. A
fi nal spin fi nishes the cycle.
Note: All rinse cycles use cold water and the
Automatic Temperature Control (ATC) is not used.
The cold rinse is the same temperature as the
incoming cold water supply.
