Won"t spin or agitate. Makes a loud rattling noise

If this is a Whirlpool manufactured TOP LOADER (such as Roper, Estate, Kenmore, Amana, and Frigidaire), you may have a damaged or broken motor coupling. Whirlpool manufactured top loading washers use a motor coupling between the drive motor and gearcase (transmission) in place of a drive belt. This configuration is known as "direct-drive". The coupling can break through normal wear and tear. Washing frequent loads of heavy items and reduce the life span of the coupler. Common symptoms include the following:

1. No spin or agitation.
2. Washer will fill and empty.
3. Drive motor still runs.
4. Strange rattling, grinding or clicking noise during agitation or spin cycles as the drum sits still.

If your washer is exhibiting these symptoms, then its probably a safe bet that the motor coupling is bad.
