Introduction
MAKE STAINS HOWEVER YOU LIKE. WE'LL MAKE WASHING THEM SIMPLE.
Getting messy is fun. We make clean-up easier with new and innovative features such as our Stain
Removal Guide, designed to fight common stains with the push of a button.
GE's CleanSpeak™ Top Load Washer features and appearance may vary depending upon model.
SmartDispense™ TECHNOLOGY
Never measure detergent again. The washer can hold about a two-month supply of detergent
and fabric softener, and can automatically dispense the right amount for each load. The
preferred amount for each load can be adjusted. Check the indicator to see when to refill the
detergent and fabric softener.
STEAM ASSIST
Steam Assist protects fabrics, while penetrating and loosening tough stains like tomato and
grass.
STAIN REMOVAL GUIDE
Remove stains with the push of a button. The Stain Removal Guide is pre-programmed with the
Ideal wash settings to tackle four common stains: tomato, oil, dirt and grass.
SOFT-CLOSE GLASS LID
Our Soft-Close Lid uses hydraulic technology to allow the lid to open to various angles, and then
close gently every time.
CLEAR GLASS LID
See what's going on inside the washer. The clear glass lid lets you take a peek inside without
opening the washer mid-cycle.
LED WASHER BASKET LIGHT
Find every last sock with a bright LED light that effectively lights the wash basket
CLEAN SPEAK COMMUNICATION SYSTEM
Perfect drying performance is achievable thanks to the ability of the washer to communicate
with the dryer to preset the dry cycle.
HYDRO HEATER INTERNAL WATER HEATER
Boosts water temperatures and helps achieve sanitization.
QUIETPACK
Enjoy a powerful clean that you won't hear thanks to noise dampening material that holds in
sound for a quieter cycle.
VIBRATION CONTROL
Wash without the shake. Quietly washes any size load without vibration thanks to technology
that optimizes spin pattern.
ENERGY EFFICIENT
ENERGY STAR® qualified and CEE Tier lll meets or exceeds federal guidelines for energy
efficiency for year-round energy and money savings.
—6—
eMonitor
Get the energy saving insight you need to reduce your utility bills with an electronic readout that
shows the efficiency level of each load.
eWash™
Energy saving option uses a cold water wash on select cycles without sacrificing performance.
FLEXIBLE CAPACITY
Take clean further with large, flexible capacity. GE’s largest capacity top load washer and dryer
help you get more laundry done in less time.
DEEP TUB ACCESS
Easily reach the bottom. Deep tub access offers an ergonomically designed wash basket
opening so anyone can easily reach the bottom.
PERSONALIZED SETTINGS
With My Settings, you can wash and dry your clothes with the settings you prefer on any cycle,
and save them as favorites.

SmartDispense ""
The SmartDispense™ feature allows the user to set their liquid h.e. (High Efficiency) detergent and/
or softener dispensing preferences for their load. This feature can be used with any wash cycle,
except for Quick Rinse, Drain & Spin and BASKETclean cycles.
The SmartDispense™ system automatically dispenses liquid h.e. (High Efficiency) detergent and/or
concentrated liquid fabric softener into each cycle at the optimal times.
To utilize the SmartDispense™ dispensers, they must first be filled. Although any liquid h.e. (High
Efficiency) laundry detergent and concentrated liquid fabric softener can be used in the
SmartDispense™ system, all liquid h.e. (High Efficiency) detergents and concentrated liquid fabric
softeners are not the same.
CAUTION! Absolutely do not store liquid chlorine bleach, powder detergent, non-
concentrated liquid fabric softener or other laundry additives in any of the tanks. Use only
liquid detergent which has been specifically designed for use in High Efficiency washers.

Redistribution Attempts
The washer will only attempt to redistribute an out of balance load one time per cycle in the final spin up. The
redistribution attempt consists of the follow sequence.
The washer will try to reach the target spin speed five consecutive times. It will spin, then stop to let the
clothes fall back to the bottom of the basket. Then it will attempt a second spin. This may occur up to five
times, although it may not need to use all of the spin attempts if it reaches its target spin speed.
If the washer cannot get to the target spin speed, it will stop, then fill the basket with water appropriate for
the selected cycle load size. Once the filling is complete, the washer will switch to agitate to jog the
clothes and redistribute the clothes in the basket. After this redistribution attempt is completed, the
basket will drain the water. This step is considered the redistribution, not the spin attempts.
The washer will then switch to spin again and make another attempt to reach the target spin speed. The
target spin speed may be reached on the first attempt. However, if the target spin speed is not reached, it
will go through another set of 5 sequential tries to reach the target spin speed. If it does not reach the
target spin speed it will spin at the highest spin speed it was able to obtain. In this example, a customer
may possibly report that their clothes came out wet.
This process can add up to 30 minutes to the cycle.

Lid Lock
The lid lock is used to prevent injuries incurred from
moving parts. Once the cycle starts, the lid lock is
engaged, locking the lid. The lid lock assembly also
contains the lid switch. The lid lock and the lid
switch are one assembly. The lid switch needs to be

Leveling Legs
Keeping the washer level is critical because the
clearance of the tub to the outer cabinet is minimal.
It is normal for the tub to bump against the outer
wrapper during usage, which the washer uses to
sense when the load is out of balance.
Adjustment
Move the washer into its final position. Place a level
on a flat top side edge of the washer. Adjust all four
leveling legs by screwing them into or out of the foot
brackets until the washer is level from left to right
and front to back.
Should any of the leveling legs show signs of
damage, order a new leg.

Motor Insulator Platform Assembly
The Motor Insulator is a thin plastic covering
required by UL, that is designed to prevent the
stator coils from coming into contact with the
platform. The isolator is located under the mode
shifter and stator, and is held in place by sticky tabs.
When the stator is installed, the isolator will roll over
the sides of the platform creating a barrier between
the stator and the platform assembly.
The platform assembly consists of a shaft and a
tube, with no gears or grease. If the wash cycle is in
agitate mode, the inner shaft will have the only
movement. If the cycle is in the spin mode, both the
inner shaft and the outer tube will move to allow
both the impeller and the basket to turn. This is
done from the action of the mode shifter. The
platform also acts as the mounting plate for the
mode shifter and stator.
Platform Assembly Removal
1. Remove the impeller. (See Impeller Removal
for instructions).
2. Remove the 1-5/16 in. hub nut.
Motor Insulator Removal
1. The rotor and stator must be removed before
removing the insulator. (See Rotor Removal
and Stator Removal for instructions). Pull the
insulator off of the platform assembly, the rotor,

used.
For the GTWN815 — GTWN845 models, the 5
coil valve is used.
For the GTWS865 models, the 6 coil valve is
used.
Diagnosing the Water Valve
° [If no water is coming out of the valve, check the
Inlet hoses and water valve screens to make
sure they are not clogged.
° |f water is still not coming out of the valve, put
the control into Service Mode and apply voltage
to the water valve coil that is not working. Check
for 120 VAC on the corresponding colored wire
at the J702 connector on the inverter board to
the white wire at the J101 on the inverter board.
Also, the resistance of the coil can be checked at
those same connectors. The resistance should
read approximately 1k ohms (1000 ohms).
* |f no resistance is present, check for resistance
at the coil. This will verify whether or not there is
an open harness.
“H20 Supply” scrolling on the control is caused by
the control not sensing water going into the tub.
If the water is going into the tub, check the pressure
sensor readings with NewFi or by checking the Hz
output from the pressure sensor in approximate
comparison to the amount of water in the tub. Check
the harness and the connections along with the
pressure sensor tube.
If no water is flowing into the tub, check the house
water supply. Make sure that it is turned on, and that
the house doesn't just have low water pressure.
If water is still not flowing into the tub, or only a low
amount of water is flowing into the tub, check the
hose screens for debris. If debris is present, clean
the hose screens. Also check the hoses for kinks.
If there is still no water or a low amount of water
flowing into the tub, check or clean the water valve
screens.
If still no water is flowing, replace the water valve.

Pressure Sensor
For models equipped with a pressure sensor, the
pressure sensor status will be determined by
reading the frequency coming from the pressure
sensor.
Pressure Sensor Removal
1.
The pressure sensor is located in the backsplash
area. Remove the backsplash assembly.* (See
Backsplash Removal for instructions). *With
the tub in an empty state.
Use pliers to compress the locking tab that is
holding the sensor in its housing, and onto the
backsplash bottom.
—
Disconnect the sensor wire connector by
pushing up on the tab above the wire connector
and pull the connector from the sensor.
Pressure Sensor Reinstallation
1. To reinstall the pressure sensor, reconnect the
pressure tube to the sensor, and also to the
harness connector.
2. Push the clip of the pressure sensor back onto
the backsplash bottom.
Pressure Sensor Diagnostics
If the pressure sensor’s frequency is outside of the
“Valid Values” illustrated in the Tub Water Level /
Hz Conversion chart, then an error condition is set.
The error condition will be logged in Service Mode.
If a Pressure Sensor error occurs during a cycle, the
cycle will be canceled and the control should go to
an Idle state.
If a cycle is started during a Pressure Sensor error,
the fill cycle will be cancelled.
— 73 —
Pressure Sensor Testing
Use a hertz meter to read the frequency at specified
water levels.
For testing at the pressure sensor, the pin out is as
follows:
1 = Ground
2 = Signal
3=5V
Test between pins 1 and 3 to verify that 5 VDC is
going to the sensor. This is needed to be able to
read the signal coming from the sensor.
Test between pins 1 and 2 to measure the signal.

Water Levels
Water levels can vary depending on the load being
washed. This can be attributed to the weight of the
items in the load, which is what sets the water level
in most cycles.
The level will vary from a minimum of 7 gallons to 25
gallons.
NOTICE
Water should always cover all valley areas (as
shown below) when a cycle is run with an empty
basket. There are four valley areas located
between the fins of the impeller. The valley areas
can be identified on the impeller by the four
sections with holes, which are designed to help
circulation within the basket.
If there is less than 7 gallons in the basket, then
water pressure from the home supply, or debris in
the water valve or hose screens may be the cause.

Top Cover Dispenser
Cups
The dispenser cups are used to either direct the
fluid into the tub assembly immediately during the
cycle, or to hold the fluid and dispense at a specific
time in the cycle. This occurs by flushing the
dispenser cups with water from the water valve.
Fabric Softener-Cup Hybrid Assembly Operation
RAE
Softener Water
To start the flow of fabric softener, water enters the
cup first, filling the reservoir and mixing with the
fabric softener. A restriction in the fabric softener
cup tubing (Venturi) creates a back pressure. The
back pressure forces water up and around the
outside edge of the cup to add water to the cup. The
water then enters the cup through two openings,
which begins to siphon the softener out. As the
pressurized water flows through to the other side of
the tube in the cup, a suction is created. The water
and softener mix together, and come out of the other
end of the cup and flows to the fill funnel. After the
water is shut off, the softener continues to siphon
out of the cup until the cup is empty.
Dispenser Cup Removal
1. With the top cover still installed, place the thumb
of one hand under the corner of the cup on the
underside of the top cover assembly.
— 75 —
. Place the thumb of the other hand inside the cup
from the top side of the top cover. With firm
pressure, pull down with the one thumb on the
underside while pushing down with the other
thumb from the top side.
The cup should pop free from the top cover tabs.
Once the cup is free, it can be slid out from
under the top cover. Remove the clamp and pull
the tube off of the cup. The clamp will not be
reusable, and will have to be replaced with a
new clamp at reassembly.
Dispenser Cup Reassembly
1.
Install the tube onto the new cup using the small
click clamp. (Refer to the click clamp instructions
found in Water Valve Assembly
Reinstallation).
Straighten the tabs on the top cover hole
opening so that the cup can slide into place
easily around the tabs.
Push up and hold the cup in place. Bend the
tabs over to about a 45 degree position to hold
the cup to the top cover. This can be done either
thumb pressure or coated jaws or the handle of a
pair of pliers. Be careful not to damage the top
cover finish.

Remove the hose clamps at the bottom of the
bulk tank. (Refer to the click clamp instructions
found in Water Valve Assembly
Reinstallation). If there is fluid still in the tank,
block the opening where the tube connects to
the tank with thumb to prevent any leakage from
the tank. Also have a towel under it to prevent a
mess on the floor.
Bulk Dispenser Tank Reassembly
1.
With the washer still leaning back or laying on its
side, slide the tank in at a 45 degree angle.
Make sure to reconnect the hose back to the
tank using a small click clamp.
Slide the tank up and in alongside the front
corner of the cabinet.
Maneuver the top of the tank around the front
suspension rod.
. Once the top of the tank is in place, it will lock
into position.
Once locked into position at the top, apply
pressure while pushing the tank in until both tank
posts are secured on the bottom lip of the
cabinet. Once locked in, the pressure will hold
the tank in position and also prevent the tank
from rattling on the cabinet.
Bulk Tank Pressure
Sensors
The bulk tank pressure sensors, one for each tank,
are located at the back of the unit. They are
mounted to a plastic bracket that sits over the rear
leg posts. Slots in the bracket hold them in place to
the cabinet. The sensors are used to measure the
amount of fluid that is in the bulk tanks.
Pressure Sensor for Bulk Tanks Removal

Tank Pressure Sensor Diagnostics
If no liquid is being dispensed from the bulk tanks,
check the water valve operation in the Service
Mode. Make sure the tanks are full, and that the
water pressure going to the tub is good. The hose or
water valve screen could be clogged. Check the
bulk tank pressure sensors to make sure that they
are in range, that they are connected, and that
power is going to them. If there is no power, check
for a broken wire to the sensor.
NOTICE
If the bulk tanks are empty of either fabric softener
or detergent, the tank level indicators will flash
three times, and the cycle will not start. This can
be bypassed by turning off the bulk tanks, and
applying detergent manually.
Diagnosing the bulk tank sensors can be done at
the sensor or from the J502 connector on the IMC
board.
Use a hertz meter to read the signal at specified
tank fluid levels.
For testing the pressure sensor, the pin out is the
same as the pressure sensor for the basket water
levels and are as follows:
1 = Ground
2 = Signal
3=5V
Test between pins 1 and 3 to verify that 5 VDC is
going to the sensor. This is needed to be able to
read the signal coming from the sensor.
Test between pins 1 and 2 to measure the signal.

Heater Assem b ly Heater Assembly Reassembly
1.
The heater is 1200 watt, 12 ohms with a 10 amp
draw. It is located toward the back of the washer
where the sump hose connects to the tub. If there is
room available, it is easiest to remove the heater
after the rear panel is removed. (See Rear Panel
Removal for instructions).
Heater Assembly Removal
1. Disconnect the harness from the heater.
2. Loosen the 10 mm nut and slide the heater out
from the tub opening.
— 83 —
Slide the heater assembly into the tub opening
until it is seated inside the tub. Be sure that the
foot at the end of the heater is pointing down.
Using an inch Ib. torque wrench, tighten the 10
mm nut to 3 1/2 inch pounds.
Using a 10 mm wrench or socket, tighten the 10
mm nut three more complete turns to get the
proper seal between the heater and the tub.
Tug on the heater assembly to make sure it will
not come out.
Reconnect the harness onto the heater
terminals.
Heater Assembly Diagnostics
If diagnosing at the heater, put the control into
Service Mode. Connect an amp meter to one of the
wires going to the heater. The reading should read
approximately 10 amps. If there is no amperage
reading, check the resistance of the heater, it should
read 12 ohms.
To check the heater diagnostics from the IMC board,
check the J803 connector from the black wire to the
white wire. The resistance should be approximately
12 ohms, and the amperage draw should be
approximately 10 amps. The brown wire that is on
the heater sheath goes to the J501. This is the
continuity circuit with the yellow wire at the
thermistor.
NOTICE
To read continuity there needs to be water in the
tub. This circuit was removed on models
produced after March 2013 as it was not needed
with updated programing that was used in
production. Some harnesses have the connectors
removed that was used for this circuit.

Tub Thermistor
The thermistor is used to sense the water
temperature in the tub, and also for the steam assist
cycle.
IF THE TEMPERATURE NEEDS TO BE TAKEN,
WAIT AT LEAST TWO MINUTES AFTER
AGITATION/RECIRCULATION HAS BEGUN.
Tub Thermistor Removal
1. The thermistor is located in the bottom of the
outer tub assembly, next to the drain pump.
Remove the two 5/16 in. hex screws to remove
the thermistor.
2. Once the tub thermistor is removed, there are
two different possible configurations for the
harness wiring to the thermistor. Some models
may present a separate yellow wire connected
to a ring terminal mounted underneath one of the
thermistor assembly screws. Some units may
not have a separate yellow wire.
Unit with no separate
yellow wire.
Unit with separate
yellow wire.
3. If the yellow wire with the ring terminal is
present, carefully lift it out of the way and protect
it from damage. It will be reinstalled in the same
location in a later step.
— 84 —
4. Cut both azure (blue) wire leads flush with the
rear black seal of the old tub thermistor to keep
the azure leads coming from the harness as
long as possible.
5. The leads are interchangeable when splicing so
there is no need to label them.
Tub Thermistor Reassembly
1. Splice the thermistor back onto the main
harness.
2. Slide the new thermistor into the tub assembly.
3. Fasten the new thermistor with the two 5/15 in.
hex screws.
4. If there is a yellow wire with a connector on it,
slide it onto the hex screw before installing the
hex screws through the thermistor.
Make sure the rubber O-ring is in place before
reinstalling the new thermistor into the tub.
5. Torque the hex screws to 17 in. pounds.
Thermistor Diagnostics from the IMC board.
To test the thermistor with the tub empty, take the
ambient room temperature with a thermometer to
see if the thermistor is within plus or minus 5
degrees. If good, turn on the TAP COLD water into
the tub and measure the incoming water
temperature at the fill funnel. The thermistor reading
should drop to within what the thermometer is
reading, plus or minus 5 degrees.
From the J501 connector, check thermistor
resistance between the two azure wires.
