Lid Lock Step 2
Press the START button to begin the wash cycle.
Power is sent to terminal 3, activating the solenoid, turning the green cam 30 deg.
Then locking pin falls in place, closing the circuit at terminal 5, sending a signal to the board that
the lid is locked. This terminates power to terminal 3.
The lock signal from terminal 5 to the board now allows the motor to run..
Note: The board looks for this lock signal with a pulse up to 5 times. If it does not receive this
signal it will show F8. The board will repeat this up to 3 times (with a 30 seconds pause between
each try). If the lid still does not lock, an ERROR code Er8 will be shown and unit no longer oper-
ate until unplugged and re-plugged or serviced.
