Hi, my name is XXXXX XXXXX I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. There is a way to open it but it is not supposed to. You can take a string and slide it between the door and seal. Slide the string holding the string above and below the door and slide the string past the latch.
Very good. It will have to be a bit of a strong string. Sounds like you have a good grasp on what has been explained. If it sounds like a latch tries to open but it is getting stuck it may just be a matter of some silicone spray on the moving parts on the latch. Do not use petroleum products for lubricant. If it gets on any seals it will damage them.
The spray is for after the door is open. I know this is a different washer model here is a video of what I am suggesting. http://www.youtube.com/watch?v=gSF4JS2B_U0
Have you been able to open the door?
