If the washer will not unlock at the end of a wash cycle unplug the washer or disconnect power.
Maytag neptune washer door lock.
Front loaders have a locking mechanism to avoid opening the door during a washing cycle but occasionally this lock will be activated accidentally.
Be very careful hacking that door.
It is locked shut with a load of clothes in it.
After the second repair i researched it and had an inline fuse put in the wiring to protect the board if the motor that locks the door overloads.
I am not sure if it is the exact same washer but we had a neptune and if the wax motor overloaded it blew the main board.
Were you using a fresh hold cycle available on some models.
