J.O.
It sounds like the lid switch (the little hole that stops the washer from spinning when you open during a spin cycle) has come loose or broken. Check and see if it's hanging down -- you may be able to insert a pen or screwdriver (something thin and long) and make it work manually to get the water out. Then you can probably rig it to work until you get it repaired.
Let me see if I can find a tutorial on it. Be back in a minute!
ETA: Okay, here are a couple of sites that aren't too terribly technical. One has video that may help explain what I was saying to do.
