To clarify you are just looking to open the washing machine door this is rather simple and works for almost every washing machine.
A video showing you what to do can be found here.
Basically you find some fine string \ fishing wire, wrap it around two objects you can use handles and slip it between the door seal and then apply pressure towards the hinges and the catch is released.
Please dont apply to much force as you may damage the washer seal or break the door catch, you will see by the video it doesnt require a great deal of force.
Please let me know if you have any other questions, or need something clarified.
