After loading the clothing, the door should be closed and latched. The locking cam on
the door contacts the latching switch actuator which closes the latching switch. The
specifi ed number of coins should now be added to start the washer. The solenoid pulls
up on the locking pawl by use of a linkage rod. The locking pawl has two jobs. The fi rst
is to lock the door. This is accomplished by blocking the locking cam on the door so
that it can’t rotate to unlock. The second job is to close the two piggyback lock sensing
switches. These switches control power to all of the controls. If the door unlocks for
any reason, these two switches will stop the machine. When the door handle is 1/4 to
1/2 of an inch from its fully closed position, the latching switch should close. The two
piggyback lock sensing switches should be open when the door is unlocked and should
be closed when the door is locked.
Accessing the Door Lock Assembly
Step 1: Set door cam over pin. Here you
can see the Door CAM away from the door
lock assembly.
Step 2: Tighten spring screw on switch
actuator arm until it just clears cam OD.
(Note : Spring screw will have approx. 1/8”
thread exposed at end beyond nut. This is
where you want clearance.)
