Basic Wash Cycle

identification and location of washer components.
After a load is placed in the basket, the user
selects the appropriate wash cycle on the LCD
touch screen and presses start.
Cycle time and wash patterns will vary depending
on user time adjustments, soil level adjustments,
fabric type, and wash-load weight.
Dry Load Sensing
Before an initial fill, the infusor rotates the dry
clothes load. This rotation is controlled by the
inverter which measures the amount of time it
takes for the motor to coast to a stop. The larger
the clothes load, the less momentum the motor
is capable of generating, so the faster it will stop.
The infusor will rotate back and forth up to four
times. This information is used to determine the
initial water fill level.
Water Fill
The washer automatically fills to the proper
level based on the load sensing measurements.
Depending on the cycle chosen and the quantity
of clothes, there are 27 possible water levels.
This information is stored in memory for the final
rinse at the end of the wash cycle. Water levels
are matched to load size using approximately
one-third less water than typical top load
washers.
Note: The washer can use as little as 17.5
gallons of water for small loads and has an
average water use of 27 gallons per load.
Wet Load Sensing
After the first fill, the infusor and basket lock
together and rotate to measure the clothes
load. During this time, the motor momentum
is measured again. The washer compares this
information to the previous dry load sensing
measurements and determines if additional water
is required.
Operation Overview
Note: Dry load and wet load sensing are used on
all cycles except the following:
for
SNEAKERS
COMFORTERS
BLANKETS (OTHERS)
BLANKETS (COTTONS)
THROW RUGS (WASHABLE)
The SNEAKERS cycle defaults to the minimum
water level. BLANKETS, THROW RUGS and
COMFORTERS cycle default to the maximum
water level.
Wash Water Temperature
During the fill, the washer monitors and regulates
wash water temperatures within 5°F (-15°C) of
the target temperature. This accuracy is achieved
using a thermistor, located in the outer tub, which
monitors the tub water temperature during the fill
cycle.
Based on information received from the
thermistor, the inverter controls the hot and
cold inlet valves to achieve the desired wash
temperature. (See
Temp
Target Water Temperatures:
Hot - 120°F (49°C)
Warm - 105°F (41°C)
Cold - 80°F (27°C)
Very Cold - 60°F (16°C)
During the fill, the basket slowly rotates in
a clockwise direction. This action mixes the
detergent and water to assure proper distribution
and assure the thermistor is reading an accurate
basket water temperature.
Basket Wash
The infusor and wash basket lock together and
rotate clockwise and then counterclockwise.
This action mixes the detergent and water while
distributing the clothes evenly in the wash water.
The basket wash speed is based on fabric type
and load size. Delicate fabrics are gently rotated
while heavier fabrics are rotated more vigorously.
