Washing Machine Won't Drain

My washing machine stopped draining the water out of itself last night. I'm not sure just what happened to it, but I am hoping that the cause is as simple as the throw pillow that broke open in it clogged up its drain pipes with polyfiber fiberfill. If that is not the case... I cringe to think what a new washer might cost me if this one's drain pump burned out. Do not even want to think about it.

I'm going to go in the washroom and ladle the water out a cup at a time to drain the washer, then tug it out from the wall and see what I can sort out to fix the problem. Really hope it is as simple as a clogged pipe that is easily removed and cleaned out.
