LG FL Washer Door Lock dE and dL Error Code Troubleshooting video MP4

I got no clicks. The error would show up immediately after pushing start. I couldn't test the broken switch in the same way as in the video'; it might have been a different part number. However, replacing the switch fixed the problem. 

I got clocks with old latch and door wouldn’t lock. Replaced latch and door still didn’t lock. Main board?
