Overview
General
The GE Profile Harmony Washer is part of the GE
Profile Harmony Clothes Care system utilizing the latest developments in washing technology.
The Harmony Washer does not use the typical agitator found on conventional washers. Instead, the direct drive motor, capable of spinning at 1010 rpm, and the
304 stainless steel wash basket create a centrifugal force that pulls wash water through fabrics for a thorough cleaning action. (See
Operation Overview.
)
Harmony Washers also utilize an automatic load sensing system to determine load size and water levels. The washer automatically fills the wash basket with the appropriate amount of water needed for optimal wash performance.
POWER
MY CYCLES
BACK
HELP
HOME
Other features include:
Communication Link to the Dryer - The washer uses a serial cable to automatically inform the dryer about the nature of the wash load, essentially presetting the dryer controls so the user doesn’t have to.
Auto-Balance Suspension - The washer is programmed to correct out of balance situations. (See
Operation Overview.
)
Flow-Thru
TM
Dispensers - Each of the four dispensers is timed to release at the right time during the wash cycle. Each reservoir is flushed with water to pre-dilute the product before adding it to the washer.
This flushing action removes all product to help keep the compartment clean and free flowing.
Note: The bleach dispenser fills during the main wash to dispense the bleach and refills during the rinse cycle to flush any reaming bleach from the reservoir.
Direct Drive Motor - The washer does not use a transmission or mechanical brake. Direct drive technology results in fewer moving parts for smooth, quiet operation. (See
Motor Assembly
.)
Infusor
TM
Wash - The washer has specific cycles that aids in mixing the detergent/water solution, and dispersing the load evenly in the wash water. (See
Operation Overview
).
LCD Touch screen Display - All washer control functions, cycles, troubleshooting, and field service diagnostics are accessed through a touch screen display. The washer can also be powered up by touching anywhere on the touch screen or any key on the keypanel.
Centrifugal Wash - The washer uses a centrifugal washing action to clean clothes instead of an agitator.
The basket spins creating a strong flow of water under the centrifugal force. As water passes through the fabric, its natural cleansing action washes away dirt without damaging or tangling the fabric.
Plastic Top & Backsplash - The washer top and backsplash have UV stabilizers to prevent yellowing when exposed to sunlight.

Operation Overview
Basic Wash Cycle
Note: See
Component Locator Views
for 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.
Note: Dry load and wet load sensing are used on all cycles except the following:
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
Thermistor/ATC Control Auto
Temp
.)
Target Water Temperatures:
Hot - 120°F (49°C)
Warm - 105°F (41°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.
– 17 –
Centrifusion Wash
The locked infusor and wash basket begin a clockwise spin (figure 1). The speed of the spin is customized to the load type and fabric type. As the basket spins faster, it creates a strong flow of water under the centrifugal force (figure 2).
As water passes through the fabric, its natural cleansing action washes away dirt without damaging or tangling the fabric.
Water
Current
Fabric
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.
Soil
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 first. 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
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 refills 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 final rinse.
Final Rinse
The washer retrieves the information it gathered for adaptive fill cycle and uses that information to refill the washer for the final 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 fills to the optimal level and goes into a basket wash cycle where the clothes and fabric softener are mixed thoroughly. A final spin finishes the cycle.
Note: All rinse cycles use cold water and the
(ATC) automatic temperature control is not used.
The cold rinse is the same temperature as the incoming cold water supply.

• After 5 minutes, if there is no additional screen input, the washer shuts off and the power LED shuts off. There is no voltage on pins 1 and 3 and 1 and 4 at this time.
• If the washer operates through a cycle, the inverter voltages at CON2 will be present until the lid is opened.
• If the Power LED is lit and any of the three voltages (5 VDC, 12 VDC, 20 VDC) at CON2 are not present, the inverter is bad.
Brake Resistor
• The brake resistor absorbs energy from the
reversing of the motor during the brake cycle.
• The brake resistor only operates when the washer is unplugged or the lid is lifted during a cycle.
• Under normal operation, the tub coasts to a stop at the end of a cycle.
• The approximate resistance value of the brake resistor is 70 Ω.
• If the resistor is shorted, the motor will not start.
• If the resistor opens while the motor is spinning, the inverter board can be damaged.
• Look for a burnt IC labeled IC300 on the inverter board. Both the resistor and inverter board should be replaced if the IC300 is damaged. (See

• When the water level rises in the washer tub, air is trapped in the reservoir. As the water level rises, the air pressure in the reservoir increases.
• The pressure is translated into an electrical signal (frequency) by the pressure sensor.
• The frequency will vary from approximately 27 kHz (empty tub) to 22 kHz (full tub).
• This frequency can be measured at the pressure sensor between the purple and orange wires.
The frequency is monitored by the inverter which turns off the water valves when the desired water level is achieved.
Note: The water level will vary depending on the load size which is measured by the dry load and wet load sensing cycles. This information is sent to the inverter, which then determines the appropriate water level.
Pressure Sensor Test
If the pressure sensor is not operating correctly, perform the following test:
1. Set the wash cycle to SNEAKERS. This cycle bypasses the load sensing feature and defaults to the minimum water level.
2. Measure the water level from the center hub of the infusor (it should be approximately
2 inches deep in the tub).
3. Set the washer to COMFORTER. This cycle bypasses the load sensing feature and defaults to the maximum water level.
4. Measure the water level from the center hub of the infusor (it should be approximately
11 inches deep in the tub).
Note: Before disconnecting the hose from the pressure sensor, be sure the water level is below the bottom of the spin basket.
To remove the pressure sensor:
1. Remove the 2 Phillips head screws that hold the
Backsplash
in place.
2. Place a towel over the lid of the washer to prevent scratches to the surface. Gently lift each corner of the backsplash, then roll it forward so it rests on top of the washer.
3. Remove the 3 Phillips head screws that hold protective cover in place.
4. Disconnect wiring to the pressure sensor.

• The Hall sensor measures approximately
9K Ω between the brown and blue wires and the brown and red wires.
• If the sensor has failed, the motor will not operate.
• The Hall sensor is part of the stator assembly.
It is not available as a separate part.
To check the Hall sensor voltage at the inverter:
• Disconnect the Hall sensor plug from the inverter board. Check voltage on pins
3 (brown) and 4 (yellow) on the inverter board. There should be approximately 12
VDC. If not, the inverter board is bad.

Clutch Shifter Assembly
The clutch assembly locks or unlocks the basket and infusor together, depending on the wash cycle pattern. (See
Basic Wash Cycle
for a brief description of wash cycles.)
• The infusor is connected directly to the motor shaft. Whenever the motor is rotating, the infusor is rotating.
• The clutch only locks or unlocks the wash basket.
When the washer first starts a cycle, the infusor moves back and forth several times to make sure the basket and infusor are in the unlocked position before starting. This action is called “clutching” and confirms that the clutch motor is in the unlocked position.
Note: Wash cycle patterns will vary depending on user time adjustments, soil level adjustments, fabric types, and wash-load weights.
The infusor and basket are in the locked position during the following cycles:
• Water Fill
• Wet Load Sensing
• Basket Wash
• Centrifusion Wash
• Spin
• Spray Rinse
The infusor and the basket are in the unlocked position during the following cycles:
• Dry Load Sensing
• Infusor Wash

Operation
(Continued Next Page)
Clutch Operation
• The clutch locks and unlocks the basket by engaging teeth on the inside of the rotor with teeth on the clutch coupler.
• When the basket and infusor are in the locked position, the clutch moves downward and engages the rotor and clutch coupler teeth allowing the basket to rotate with the infusor.
Rotor Teeth
To diagnose the clutch motor:
• The inverter supplies 120 VAC to the clutch motor through the brown and white wires when the clutch motor changes position.
Note: Disconnect power and unplug the clutch motor connector at the inverter board.
• The clutch motor has an approximate resistance value of 2000 Ω. This can be measured between the white and brown wires on the inverter board. (See
Inverter and Main
Board Pin Connectors.
)
• The rotation of the clutch motor causes an internal switch to open or close. This can be measured between the brown and blue wires on the inverter board.
• When the clutch is in the unlocked position the switch should be closed (0 Ω).
• When the clutch is in the locked position the switch should be open (infinity).
