Top-load washer agitator does not move clothes properly; only the bottom moves or it slips.

Safety First: Unplug the washer before reaching into the tub.

Step-by-step checks:

• 1. Test agitator: Try turning the upper agitator section by hand. If it turns freely in both directions, the dogs are worn.
• 2. Remove agitator: Pull off the fabric softener cap, remove the inner cap, and use a socket to remove the agitator bolt. Lift the agitator out.
• 3. Replace dogs: Separate the upper agitator and replace the small plastic agitator dogs with a new set. Reassemble and reinstall the agitator, tightening the bolt firmly.
