Sorry, buts that funny!!
If your machine has gone legs up then basically you can't
You could try the gravity method and tilt the machine gradually backwards allowing the water to exit via the hose into a bucket
The door WILL open (after a wait) once you have disconnected power
Maybe get a few friends and carry the machine outside so you can flood the garden
Wish I was there to help. Sounds like you've waved the washing machine goodbye but want your clothes back? Hilarious!
Good luck X
