re: LG front load washer PE code

If it's not the switch, or the hosem, then it's the board.

LG's are known to have board issues, I know it would suck to put a $150 part in, but you have a pressure error.
If you know the switch is good and you have a clear hose, then it likely is the control.

Remove the black tube from the Water Pressure Sensor---and blow through it.

Remove/re-connect all plugs on the Main Board

Inspect all wiring that leads/runs from the Water Pressure Sensor-to-the Main Board.
You're looking for wiring damage caused by a wildly-out-of-control spinning tub assy---slamming into the wire loom.

Test Washer.

If still malfunctioning---replace the MAIN BOARD.
