How to enter Diagnostic Mode GE Washer GCVH6400J1WW

Tried a number of Google suggestions but did not work. I probably did not perform the steps correctly

To enter diagnostic mode on your GE Washer GCVH6400J1WW, keep the door closed and simultaneously press and hold the Power and Start buttons. Holding the buttons in place, rotate the cycle selector knob 180° clockwise. The lights will flash and the washer will be in diagnostic mode and ready for display of error codes or testing.

I found the correct procedure in the service sheet behind the kick panel. "recently plugged in + signal- delay,-signal- delay"

The error code was 60, for the door lock. The machine was adding time during a cycle.
