Section 2. Washer Controls Overview
DOOR LOCK PHILOSOPHY
The door lock mechanism is checked
by the machine control board for
proper operation. This is done in the
following manner.
1. The door will be locked. If the door
does not lock on the first try, a help
code 47 is logged into the control
memory. The display will show the
door has not locked.
2. If the door lock switch check shows
that the door is locked, then the door
will be unlocked and the cycle will
continue unless the door fails to
unlock. If the door fails to unlock, the
cycle will be paused until the door is
able to unlock for 30 seconds and lock
again.
DOOR LOCK OPERATION
1. By closing the door, the door lock
hoop rotates the catch cam and the
door actuator is depressed actuating
the door open/closed microswitch.
MISCELLANEOUS 2. A 60 milliseconcd 120 VAC impulse
from the machine control board to the
lock solenoid extends the push rod of
the solenoid and moves the lock lever
to the right only to lock the door. The
lock lever in turn is engaged with the
slider and slides the slider toward the
door lock mechanism and inhibits the
door lock mechanism from releasing
the door lock hoop of the door.
5. The slider will actuate the door lock/
unlock microswitch in the locked
position and the washer will begin the
wash cycle.
6. When the wash cycle is finished an
impulse from the machine control
board to the unlocking solenoid
unlocks the door by pulling the slider
away from the door latching
mechanism and the lock/unlock
microswitch.
7. The consumer can now open the door.
8. By opening the door, the open/closed
microswitch is open.
