Engineering Revision

– 5 –
The new Profile washers have the following features:
HydroWave™ with Infusor™ wash system gently pulls fabric through the water using up to a 630-degree•
reversing arc motion for a gentle, yet thorough, clean.
4.1 cu. ft. colossal capacity handles king-size items and family-size loads, which results in fewer loads•
and less time.
ENERGY STAR® qualified meets or exceeds 2009 federal guidelines for year-round energy efficiency and•
money savings.
Auto fill system - Automatically measures the load and fills the appropriate amount of water.•
Enhanced load size control - Load size position to enable auto fill feature.•
Variable speed inverter/motor assembly - Provides multiple speeds for delicate to heavy clothes.•
Multiple wash/spin speed combinations - Speeds are matched to fabric type for better clothes care.•
Field Service Mode for electronic diagnostic testing.•
New flow controlled water valve provides•
constant flow rate of water for the auto fill
feature.
Counterweight (5 lbs.) has been added•
for better balance control (available as a
replacement part).

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

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.

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.
