I get an error code: F dU and my washer won't drain properly

I too, had the same issue with the door not opening. My solution was to unplug the power cord and then plug it back in and press the green button's as if to start a cycle and while it starts putting water into the washer I put my knee and weight into the door lock area and held pressure from my knee and press the red stop button until the lights went out, and I took my knee off the door lock area and opened the door!!! No taking off the lower panel.
If this works for you too please email me [email protected].

FDU is Door Unlock error.

A Door Unlock Error occurs if the door cannot be unlocked. It will try to unlock the door six times before displaying the error code.

Possible Causes / Procedure
