I have a washing machine that doesn't shut off and completely overflows. Is there some kind of sensor that doesn't work or is this something that I could fix myself. It drains fine at the spin cycle. Any help is greatly appreciated.

Is it over flowing out of washer?
If so, fill valve in machine is bad. :)
