Answer to: installed a brand new switchTry this. Remove the top cover of the washer. To remove the top cover, my washer had 3 screws on the back. Once the cover has been removed, you should see the Central Control Unit (CCU). Simply give the far right terminal a little push inwards and that should to the trick. I believe the far right terminal controls the front door latch ( F DL ). If not, give all the terminals to the left a little push. I'm guessing vibration from the washer causes the terminal to shake loose which results in the F DL error code. I hope this helps.
