Unplug the washer to disconnect electrical power and remove the bottom front service panel as shown in the first image below. Carefully reach up along the front panel of the washer and pull down on the manual release tab that is on the bottom of the door lock assembly until it clicks. This should unlock the washer door.
If the door lock assembly is broken, you may be able to replace it yourself. You can order a new door lock assembly from the
website. The part number is 8182634.
The procedure for replacing the door lock assembly is provided in the second image below. Be sure that the washer is still unplugged when accessing this component. After replacing the door lock assembly, the challenging part of the repair will be to replace the spring clamp on the boot of the door opening. Start by working in the clamp on the opposite end of the spring and working evenly around both sides. Pull outward on the clamp to expand the spring as you work your way around the opening. Significant force will be needed to work this clamp back onto the washer door opening. I recommend wearing gloves during this procedure.
