Door Lock Assembly (Continued)
When a cycle is selected and the start pad is touched,
the control board applies power to the coil. The
magnetic field of the coil pulls the locking fork down and
tries to pull the contacts of the door lock switch closed.
If the washer door is open, a tab on the switch actuator
prevents the contacts from closing and the locking fork
will not allow the door to be closed until the stop pad
is touched, removing current from the coil. When the
washer door is closed, the door strike pivots the switch
actuator out of the way allowing the magnetic field of
the coil to close the contacts of the door lock switch and
the locking fork locks the door. (See Figure 1-7)
The wax motor and spin lock arm are used to prevent
the door from being opened while the spin basket is still
spinning. Power is applied to the wax motor when the
washer is in spin. When power is applied to the wax
motor, it expands its piston within 30 to 40 seconds,
driving the spin lock arm between the locking fork and
switch actuator holding the locking fork down. At the
same time, the piston closes the door lock auxiliary
switch allowing the washer to go into spin. When power
is removed from the wax motor, it takes about 90
seconds for the wax motor to cool down and retract the
piston, pulling the spin lock arm back away from the
locking fork and auxiliary switch. This provides enough
time for the spin basket to slow its rotation down to the
wash speed before the door could possibly be opened.
Pressure Switch (Select models)
The pressure switch is mounted to the right side panel
under the top of the washer and controls the water level
in the washer. (See Figure 1-8)
The pressure switch is made up of a single pole double
throw switch, but only contacts 1 and 2 are used. The
contacts are controlled by a bellow inside a sealed
chamber. The chamber is connected by a hose to the
air bell located at the bottom of the washer attached to
the drain boot. L1 power is applied to the pressure
switch by the control. If the water level is below 1/2
inch from the bottom of the spin basket, contacts 1 to 2
of the pressure switch close, applying power to one side
of the (3) solenoids of the water valve assembly. The
other side of the solenoids is connected to neutral by a
relay contacts on the control board. When the cycle calls
for water, depending on the water temperature selected
and the increment of the cycle, the control board
connects one or two of three the solenoid coils to neutral
activating the water valve solenoids. When the corrected
water level is reached contacts 1 and 2 open, signaling
the control to remove neutral from the solenoids.
