if you have already replaced the door latch /lock switch and have the same issue ,
You have a faulty CCU (main control board)
That will need to be replaced.
I suspect the door lock / unlock circuit with in the control board has failed,
When the unit first turns on the unit should lock the door ,wait 5 seconds then unlock the door wait 5 second bring in cold water ,wait 5 seconds then re-lock the door .
This function is the child safety feature .
The control board is not recognizing that the door is in fact locked that is why it is not unlocking the door.
