Basic Wash Cycle

Note: See
Component Locator Views
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 fi ll, 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 fi ll level.
Water Fill
The washer automatically fi lls 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 fi nal 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 fi rst fi ll, 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 identifi cation
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 fi ll, 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 fi ll
cycle.
Based on information received from the thermistor,
the inverter controls the hot and cold inlet valves
to achieve the desired wash temperature. (See
Thermistor/ATC Control Auto Temp
Target Water Temperatures:
Very Hot - 140°F (60°C)
Hot - 112°F (44.5°C)
Warm - 80°F (26.5°C)
Cold - 63°F (17°C)
Tap Cold - Consumer's incoming water
temperature.
During the fi ll, 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.
