whirlpool awm5145-2 front loading washer no water?

when u put on the cycle and press on the machine switch just turns a little bit then does nothingdoesnt do anything. the only thing that it will do is make a little whirrring noise. also if u set it on the seperate drain cycle it seems to work ok and then u can open the door, or if u unplug it u can open the door but not any other way. it was working fine a few days ago and then i put in some bright pink towels with a bit of salt nad soap , i may have overloaded it. as they still came out soapy.
