If the washer won't agitate, replacing the agitator repair kit may solve the problem. The kit contains the agitator components that are most likely to wear out and/or fail. If any of the parts are worn out, stripped, or damaged, replace the kit.

The drive block connects the washer transmission to the agitator. If the drive block is worn out, the transmission shaft will still move back and forth, but the agitator will only move slightly or will not move at all. Inspect the drive block for damage. If the drive block is worn out, stripped, or damaged, replace it.
On some models the lid switch assembly prevents the washer from both spinning and agitating when the lid is open. If the lid switch assembly fails, the washer will not spin or agitate. To determine if the lid switch assembly is defective, use a multimeter to test the lid switch for continuity. If the lid switch does not have continuity when the lid is closed, replace it.
On most top load machines the washer will not agitate or spin without the lid being fully closed. Close the lid after loading the washer and ensure there are no obstructions preventing the lid strike from connecting to the lid switch or latch.

05 - Alliance Washing Machine Motor Coupling
The motor coupling connects the motor to the washer transmission. If the washer is overloaded, the motor coupling will fail in order to protect both the motor and transmission. The motor coupling can also fail due to normal wear. Inspect the motor coupling to determine if it is broken. If the motor coupling is broken, replace it.
