Motor and Drive System
The new Profile washer incorporates a new motor and drive system. The 120-VAC input powers a 3-phase
induction inverter/motor assembly. The inverter produces approximately 340 VDC, which is pulse width
modulated (PWM) to control motor speed. There is no location to check inverter output voltage to the motor.
Voltage given is for information only. The motor is bidirectional, constantly reversing it’s direction to provide
agitation. The motor is connected by a belt to the shaft and mode shifter assembly. By energizing or de-
energizing a coil, the mode shifter assembly engages or disengages the shaft and tube. This allows for
agitation and spin cycle modes.
Motor status is displayed through a series of flash codes from a green LED located on the front side of the
inverter just above the motor. These codes are stored in memory until cleared. (See Inverter Motor Error
Codes.)

Shaft and Mode Shifter Overview
The shaft and mode shifter assembly consists of the shaft and tube, mode shifter cam, and mode shifter coil.
It operates in 2 distinct modes, spin and agitation.
The shaft and tube transfers power to the wash system. Motor power is transmitted to the shaft and tube
from the drive belt to the drive pulley. The drive pulley is attached to one end of the infusor shaft and the
infusor is attached to the other. The tube is fixed to the washer basket at all times.
The mode shifter changes the shaft and tube from spin to agitation. In agitation mode, the tube is fixed to
the platform and the infusor shaft rotates freely. In spin mode, the infusor shaft is fixed to the tube and both
rotate together.

MODE SHIFTER
AGITATE
PROGRAM
RUNS
(18 SEC)
Mode Shifter Operation - Agitation
The mode shifter is controlled by the motor inverter circuit. When the washer starts the agitation cycle,
the inverter energizes the mode shifter coil. The magnetic field of the coil lifts the mode shifter cam,
disengaging it from the drive pulley. Without the cam engaged, the drive pulley rotates only the
agitator shaft.
At the beginning of the agitation cycle, the inverter energizes the mode shifter coil with
135 VDC (PWM) for approximately 18 seconds. This high voltage pulls the mode shifter
cam up from the drive pulley. During this time, the motor also rotates clockwise and
counterclockwise in short strokes to ensure the mode shifter cam has been released from
the drive pulley. This operation is called the Mode Shifter Agitate Program. It is normal to
hear metal-to-metal "clunking" sounds during this time as the cam and drive pulley
disengage. The washer runs this program when the agitation cycle first starts, when
power is restored if lost during agitation or when the user restarts the washer if paused
during agitation.
Once the Mode Shifter Agitate Program has completed (18 seconds), agitation begins. During agitation,
the inverter continues to supply 30 VDC (PWM) to the mode shifter coil. This voltage is sufficient to hold
the mode shifter cam away from the drive pulley throughout the remainder of the agitation cycle.
The inverter motor controls the speed of agitation. The agitator stroke rate is approximately 30 strokes
per minute. This rate is the same for all cycles. The speed of the motor controls the arc. At fast speed,
the arc is approximately 630 degrees. At slower speeds, the arc is substantially less. It is the distance of
the arc that determines normal or gentle wash cycles.
Mode Shifter Operation - Spin
At the beginning of the spin cycle, the inverter runs a short sequence (approximately 30
seconds) to make certain the mode shifter cam is engaged with the drive pulley. The
inverter does not supply voltage to the mode shifter coil during this sequence. Since the
coil is not energized, the spring loaded cam drops down into the teeth of the drive pulley.
During this time, the motor also rotates clockwise and counterclockwise in short strokes to
ensure the cam has engaged with the drive pulley. This 30 second operation is called the
Mode Shifter Spin Program. It is normal to hear metal-to-metal "clunking" sounds during
this time as the cam and drive pulley engage.
MODE SHIFTER
SPIN
PROGRAM RUNS
(30 SEC
Notes:
If the washer is paused while in agitation, it is NORMAL to hear sounds for an additional 30 seconds as
the inverter control runs the Mode Shifter Spin Program to de-energize the coil and enter a pause state.
If the washer is in agitation and power is lost, the inverter control will run the Mode Shifter Agitate
Program when power is restored.
If the washer is in spin and power is lost, the inverter control will run the Mode Shifter Spin Program
when power is restored.
To help prevent out-of-balance conditions, the last 10 seconds of agitation on certain cycles will be
short, fast strokes to help redistribute the clothes load prior to entering the spin cycle.

Precise Fill
The manual load size settings selected by the consumer are fixed time fills, the pressure switch does not
control fill timing.
When Automatic Load sensing is selected the machine determines how long the fill timing will be by
monitoring the lower level pressure switch, the control receives the input from the lower switch and then
determines the load size and fill timing for that load.
The washer will not fill with water when automatic load sensing is selected if the lid is opened.
When the lid is closed the machine is able to begin filling with water in order to sense the load size.

Load Size
Add detergent to the bottom of the basket and fabric softener to the dispenser prior to loading clothes.
Loosely load clothes no higher than the top row of holes in the basket. For optimal performance, load items
around the outside of the basket.
Make the load selection from SMALL, MEDIUM, LARGE, EXTRA LARGE, SUPER and AUTOMATIC LOAD SENSING:
– For convenience, best performance and optimal efficiency, select AUTOMATIC LOAD SENSING. This selection
automatically provides the correct amount of water suited to the size and type of load placed in the unit.
– If you prefer to manually select the water level, select SMALL through SUPER. While AUTOMATIC LOAD
SENSING is best for most loads and general washing, you may want to manually select the load size for
specialty items such as bulky, lightweight comforters or pillows, where you want to ensure a larger water
level is applied. Manual load size selections should be made for wet items placed in the washer, such as
soaked towels or garments.
– The washer will not fill with water when automatic load sensing is selected if the lid is opened.
When the lid is closed the machine is able to begin filling with water in order to sense the load size.
NOTE: This is a high-efficiency washing machine with Infusor™ wash action. This system requires less water
while providing effective cleaning action. You may notice that the water level is lower than on your previous
washer. This is normal for an Infusor™-equipped washer. The water level will be just above the top of the
Infusor™ when the SUPER WASH size is selected.
Temperature
Select the water temperature for the wash and rinse cycles. Always follow fabric manufacturer’s care label or
instructions when laundering.
PerfecTemp senses the incoming water temperature and adjusts the fill water to obtain a more precise
temperature range for all wash temperatures. For example, in a COLD wash selection, some warm water may be
added to reach a temperature needed to better dissolve detergents. Often, detergents are not completely
dissolved in very cold water, especially in cooler climates.

During winter months, when the water entering your home is colder, or for locations with very cold water year round,
use the PerfecTemp plus COLD to help dissolve powdered detergents and to improve the cleaning of your clothes.
The TAP COLD feature turns the PerfecTemp feature on your washer off and uses your household tap water
temperature for a COLD wash. This can provide energy savings by reducing the amount of hot water used in your
wash.
Options
Autosoak Option (on some models)
This option begins with a brief agitation, soaks for a specified period of time, then moves through the rest of the cycle
automatically. On some models, this option is located on the Cycle Selector knob.
2nd Rinse Option (on some models)
When you use extra detergent or bleach to clean heavily soiled clothes, you may want to use the 2nd Rinse option.
It provides a second deep cold rinse.
Extended Spin Option (on some models)
Use this option to extract more water from your clothes. Clothes will be drier when this option is selected and will dry
more quickly in your dryer.
Fabric Softener
Set this option when adding fabric softener to the washer.
NOTE: Do not use fabric softener dispensing balls with this washer. They do not work correctly in high-efficiency
washers.
Estimated Time Remaining Display
Displays the approximate time remaining until the end of the cycle.
If the estimated time remaining is more than 60 minutes, “1H” will flash in the display followed by the additional
remaining minutes. When the time remaining is less than 60 minutes, the timer will count down.
Cycle time is affected by how long it takes the washer to fill. This depends on the water pressure in your home.
The “smart” timer “learns” the amount of time it takes to fill your washer and adjusts the total time accordingly.
Wash Cycle―Cycle Selector Knob
The wash cycle controls the length of the washing process. The knob can be turned in either direction. Turning the Cycle
Selector knob after starting a cycle will stop the washer and reset the cycle to the new selection. Press START
to begin the new cycle selection.

The water valve has a flow rate of 2.8 gallons•
per minute on the cold side and 1.8 gallons hot
side.
If the pressure switch is not satisfied within 20•
minutes, a fill error code will be recorded. If the
pressure switch has not opened in 45 minutes,
the main control will de-energize the water valve
and place the washer in pause mode.
Each solenoid coil has an approximate•
resistance value of 1.1K Ω.

Automatic Temperature Control (ATC)
The automatic temperature control (ATC) is a feature•
that utilizes a thermistor to regulate the water fill
temperature.
The thermistor has a negative temperature•
coefficient (as temperature increases, resistance
decreases).
The thermistor is located in the outlet of the fill•
funnel and will measure 50K Ωat room temperature
(77°F / 25°C).
If the thermistor reads outside the expected range•
(10K - 120K Ω), the main control will default to the
following pre-programmed fill temperature settings:
Tap Cold = cold water valve only
Cold = cold water valve only
Cool = hot and cold water valves
Colors = hot and cold water valves
Warm = hot and cold water valves
Hot = hot water valve only
When both valves are energized, the internal orifices•
in the valves meter the flow to a 60% cold and 40%
hot ratio.
With the lid open, ATC will remain activated. The•
temperature of the water entering the washer
with the lid open may vary greatly from customer
expectations due to the cycling of the fill valve
solenoids.
Extreme water temperatures at low pressure can•
cause the ATC to use it’s maximum number of
activations and revert to a preset fill routine. The
main control will not allow the water valve to cycle
more than 25 times per fill.
Resistance can be measured at the wire harness
located on the control board location J5. Make sure to
unplug the connector to isolate the thermistor before
taking resistance readings.
To determine the temperature of the incoming
water, the main control measures the difference
between the voltage sent and the voltage returned
from the thermistor. The main control then makes
temperature adjustments accordingly.

AC Line Filter
The potential exists for the washer to cause
electronic devices in the vicinity to experience
disruption. In addition, electrical devices in the
area could cause erratic behavior in the washer
electronic control. To eliminate the likelihood of
disruption, the washer is equipped with a conductive
noise filter. Should interference with electronic
devices or erratic control behavior be reported,
suspect a problem with the filter. The ground wire
attached to the filter must have a good connection
for the filter to operate properly. Check to make
certain that the ground wire is connected properly
before replacing the filter.
The filter is accessed by placing the control panel in
the service position. (See Control Panel.)
Note: When untaping and disconnecting the wires
from the AC line filter, note wire locations.
