My washing machine won't work?

I was washing a quilt and a few cloths, not enough to overload it, it turned on and ran for a while then quit, I went to take the cloths out and felt they were still damp and saw that the dial was stopped just before the rinse cycle, I pulled the nob out to turn it back on and nothing, I tried starting the cycle over again and nothing, the plug is all the way in and I checked the circut breaker and it is fine, what could be wrong with the washer?
