Help! My washer won't change cycles and keeps overflowing!

Please help! We got this washer off of Craigslist two years ago, so I’m not sure exactly how old it is. It has always worked great with no problems. But now it suddenly won’t change cycles. We have to set a timer, and physically change it to the next cycle or it will overflow and flood the entire room. And tonight it started filling with water after the spin cycle was finished, which of corse flooded the room again. We are not sure what to do. I would rather not have to call somebody to repair it. Anybody have any ideas or suggestions? Thanks in advance.

Do you feel lucky? If so, clean out the tube going from the water pressure switch to the tub, and see if that doesn’t make things right.
