Motor and Drive System
The new GE washers incorporate a new motor and drive system. The 120 VAC input powers a three 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 bi-directional, 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.

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 agitator shaft and the
agitator 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 agitator shaft rotates freely. In spin mode, the agitator 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 360 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.

Notes:
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.

Drain Pump
The drain pump is coupled to a 120 VAC, 60 Hz, 85
watt motor. The pump motor has an approximate
resistance value of 12Ω.
To remove the pump:
Note: Water will remain in hoses even when the tub
appears empty. Use care to avoid water spills.
1. Disconnect power to the machine.
2. Lower the drain hose into a small bucket to
remove any water remaining in hose.
3. Remove the front panel. (See Front Panel.)
4. Disconnect the pump wires.
5. Pinch off the black sump hose to prevent water
spills.
6. Remove hose clamps and hoses from the pump.
7. Remove two 3/8" hex-head screws.

Belt
• Since the belt provides constant tension, there is
no need for adjustments (an adjustment method
is not provided).
• A worn or damaged belt can result in excessive
brake time and will initiate a motor inverter slip-
ping belt error code. This code will prevent the
motor/inverter from operating.
• To replace the drive belt it may be helpful to use
the belt install tool (part number WX05X10102).

Note:
• A new belt will be slightly smaller than the drive pulley.
• A belt that has been installed on the drive pulley will
stretch to the diameter of the pulley over time. This is
normal and does not indicate a bad belt.
