Introduction
General
The GE Profile Harmony Washer is part of the GE Profile Clothes
Care system utilizing the latest developments in washing
technology.
The 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.)
These 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.
Other features include:
QuietClose Hydraulic Glass Lid - Extra wide glass lid closes
gently.
Flow-ThruTM Dispensers - Each of the 3 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 with water during the main wash to dispense the bleach and refills during
the rinse cycle to flush any remaining 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.)
InfusorTM Wash - The washer has specific cycles that aid in mixing the detergent/water solution and
dispersing the load evenly in the wash water. (See Operation Overview).
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.
Auto-Balance Suspension - The washer is programmed to correct out-of-balance situations. (See Operation
Overview.)
Specialty Cycles - These cycles that offer improved care for specific types of fabric now include intuitive
names to make it simple to choose the right one. These cycles, including Jeans, Towels & Sheets, or
Washable Wool, take all the guesswork out of getting the best possible results.
Antibacterial Option - The internal HydroHeaterTM extends heating cycle time to reduce certain types of
bacteria by 99.9%.
Delay Start - Set the washer to begin whenever it’s convenient.
Cycle Countdown - shows exactly how much time is remaining between loads.
Service Test Mode - Built-in service test mode that aids the service technician to quickly identify failed or
improperly operating washer components.

Using the Liquid Bleach
Dispenser
The bleach dispenser automatically
dilutes and dispenses liquid chlorine
bleach at the proper time in the wash
cycle.
1Check clothing care labels for special
instructions.
2Measure liquid bleach carefully,
following instructions on the bottle.
•Never pour undiluted liquid chlorine
bleach directly onto clothes or into
the wash basket.
•Do not pour powdered bleach into
bleach dispenser. Do not place load
items on top of the bleach dispenser
when loading and unloading the
washer.
•Avoid overfilling or splashing
when adding bleach to the
dispenser. The maximum capacity
of the bleach dispenser is one cup
of bleach per wash cycle. Overfilling
could result in early dispensing of
bleach.
3Before starting the washer, pour
measured amount of bleach directly
into bleach dispenser. If you prefer to
use powdered bleach, add it into the
wash basket directly before adding
clothes.
WARNING! Do not mix
chlorine bleach with ammonia or acids
such as vinegar and/or rust remover.
Mixing can produce a toxic gas which
may cause death.
The manufacturer’s recommended
amount of undiluted bleach goes into the
bleach dispenser. During the final
“Infusor” wash action, the bleach is added
to the wash load. This ensures
performance won’t be diminished. Two
sequential flushes through the bleach
dispenser completely remove the bleach
from the dispenser. Any residual liquid left
in the dispenser at the end of the cycle is
water, not bleach. To prevent self-
siphoning of the bleach into the wash
basket and damage to your clothes, never
add more than the maximum fill level
marked on the dispenser.
Also keep clothes away from the bleach
dispenser so they don’t absorb any bleach
droplets left around the bleach dispenser.
Using the Dispenser Drawer
The dispenser drawer contains
2 compartments:
•Liquid Fabric Softener
• Liquid or Powder Low-Sudsing,
High-Efficiency Detergent
The dispenser automatically dispenses
additives at the proper time in the wash
cycle.
1Slowly open the dispenser drawer by
pulling out the drawer until it stops.
2After adding laundry products, slowly
close the dispenser drawer. Closing the
drawer too quickly could result in early
dispensing of additives.
• Avoid overfilling or splashing when
adding laundry products to the
dispenser. Doing so could result in
early dispensing of laundry products.
At the end of the cycle, you may see
water in the compartments. This is part
of the normal operation of the washer.
NOTE: Do not use bleach in the dispenser
drawer.
TIDAL WAVE Wash System
Your washer has an innovative washing
system which uses rapid spinning
motion and an angled spray to pull
water through faberic. The TIDAL WAVE
Wash system provides a gentler and
more thorough cleaning.
TIDAL WAVE Wash is avaiable only
during COLORS/NORMAL and
WHITES/HEAVY DUTY cycles.

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 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 power
board. The power board 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
4 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 16 gallons of
water for small loads and has an average water use
of 24 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.
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. The thermistor
monitors the tub water temperature during the fill
cycle.
Based on information received from the thermistor,
the power board controls the hot and cold inlet
valves to achieve the desired wash temperature.
(See Thermistor/ATC Control (Auto Temp.)
Target Water Temperatures:
Sanitize - 140°F (60°C)
Hot - 120°F (49°C)
Warm - 95°F (35°C)
Cold - 65°F (18°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.
Tidal Wave Wash
The infusor and wash basket lock together and
rotate clockwise and then counterclockwise at
230 RPM. 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.
(Continued Next Page)
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).

– 12 –
As water passes through the fabric, its natural
cleansing action washes away dirt without
damaging or tangling the fabric.
Water
Current
Fabric Soil
Infusor Wash
Following the centrifusion wash cycle, the basket
and infusor unlock and the wash basket remains
stationary. 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.
Jet Spray Rinse
Jet Spray is used during the rinse cycles in order to
use less water. Water is sprayed over the clothes as
the basket rotates.
Jet Spray is the default rinse type unless either
FABRIC SOFTENER or EXTRA RINSE cycle additions
are selected.
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 4 times) before going to the next
cycle.
Cycle Cancellation
If the user cancels a cycle by pressing the POWER
pad, after 4 minutes the pump will turn on and
pump the water out of the tub. The control does not
illuminate and the tub does not spin. The pump is
operated until the tub is empty.
If the customer pauses a cycle for an extended
amount of time, after 2 hours have elapsed, the
machine will pump the water out of the tub and
shut off.

Pressure Sensor
The pressure sensor is connected by a clear
pressure hose to an air reservoir near the bottom
of the outer tub and operates by a frequency (kHz)
signal to the power board.
• 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 21 kHz (full tub).
• This frequency can be measured at the pressure
sensor between the purple and orange wires.
