My washer won't spin or drain, but sounds like motor is running.

Sounds like a sliped or broken belt. The motor will run but with out a belt your drum wont spin an your pump wont drain the drum because the whole washer is set up with sensers, relays, and other fun electrical parts. This depending on its age can be pricy to cheep. Its a job that will take some time and can best be covered by your warenty if there is one by your washers deler.
