MISCELLANEOUS 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. 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.
