Ok so the washer is saying Lo Flo but won’t allow me to shut it off while I figure the issue out so the question is how do I just shut the washer off so the door unlock

Unplug the washer for 2 full minutes or kill power to it at the breaker and that should reset the board and allow the door to unlock if the drain pump comes on after restoring power give it time to drain and just let the drain pump run, once it stops running if it does the door will unlock.
