Sounds like your pump is out.
Unplug the washer, is the washer leaking at all?
Turn over on side or at a workable angle. Take off pump, located on bottom next to hose line. Two screws hold it on. Take it to a place that checks these things out.
Sometimes these pumps just get clogged with lint and shut down.
These pumps are cheap and if you have a place, you could even try getting a good used one.
