Door remains locked after cycle and displays LO on screen

Question edited for clarity.

E3 is a generic 'Off Balance' code

If you receive an E3 Error code, your washer may be unbalanced. This could be caused by the washer being too tightly packed, or clothing not distributed evenly. This will usually occur during the spin cycle. Stop the spin cycle.

F8 is taking too long to fill. Check the filter screens on the rear hoses.

The F8 E1 or Lo FL error code means your washer is not detecting the correct amount of incoming water. If the washer has an F8 E1 error or LO FL error, the door may be locked, and the control may be unresponsive.
