nBoom splines connect to the splutch pulley.
nBoom splines connect to the inner splines of the splutch cam.
Splutch
The splutch is made up of ve parts:
nSpring
nHousing
nCam Ring
nBasket Drive Gear and Pulley
The pulley is connected to the agitator through the agitator sha.
The agitator always moves with the pulley. The basket drive gear is
connected to the basket by the inner splines contacng the outer splines
of the transmission. The cam ring raises and lowers the basket drive
gear. When the basket drive gear teeth are engaged to the pulley teeth

Shifter/Actuator
The actuator serves several funcons. It has a synchronous motor that
shis the splutch slider and monitors the posion of the splutch. It also
houses a transmission speed/posion opcal sensor.
A. Shifter/Actuator
The shifter motor rotates a cam, attached to the shifter arm which
moves between two positions. The shifter arm moves the transmission
lever which engages or disengages the transmission creating agitate and
spin. The washing machine is in spin when the shifter is up in this
position. The teeth of the splutch are engaged with the teeth of the
pulley and the motor turns the pulley in a direction for spin. When the
shifter pulls the lever down it disengages the teeth. The washing
machine is in agitate. The length of each stroke is controlled by the CCU.
There are three different patterns.
Agitator
Water Levels
Lid Lock
Since this washer does not ulize a brake, a lid lock is used to prevent
access during spin. During the spin cycles, a lid lock mechanism will lock
the lid. The lid must be closed for the washer to ll, wash, drain, or spin.
The lock mechanism houses a switch that senses the lid is down, a latch
solenoid and a magnec reed switch to conrm that the lid is locked.
