Installation (Setup)
Tools Required:
- Screwdriver (flathead and/or Phillips, depending on washer model)
- Socket wrench (for agitator bolt, if applicable)
- Pliers (optional)
Step-by-Step Installation:
- Disconnect Power: Unplug the washing machine from the electrical outlet to prevent electric shock. Turn off the water supply valves.
- Access the Agitator: Depending on your washing machine model, you may need to remove a cap or fabric softener dispenser from the top of the agitator to expose the agitator bolt.
- Remove the Agitator Bolt: Use a socket wrench to loosen and remove the bolt securing the agitator. Some models may have a plastic agitator cap that twists off.
- Remove the Agitator: Carefully pull the agitator straight up and out of the washer tub. It may require some force or wiggling.
- Disassemble the Agitator (if necessary): Many agitators consist of two parts: an upper and a lower section. You may need to separate these to access the agitator dogs. Look for clips or screws holding them together.
- Locate and Remove Old Agitator Dogs: The agitator dogs are small plastic or nylon pieces located inside the agitator's cam assembly. They typically sit in slots. Carefully pry out the old, worn, or broken agitator dogs.
- Install New Agitator Dogs: Insert the new UpStart Components 80040 Agitator Dogs into the designated slots. Ensure they are seated correctly and facing the proper direction (usually with the angled side facing inward).
- Reassemble the Agitator: Reattach the upper and lower sections of the agitator if they were separated.
- Reinstall the Agitator: Carefully slide the agitator back onto the agitator shaft in the washer tub. Ensure it is fully seated.
- Secure the Agitator Bolt: Reinsert and tighten the agitator bolt. Do not overtighten. Replace any caps or dispensers.
- Reconnect Power: Plug the washing machine back into the electrical outlet and turn on the water supply.

Post-Installation Check (Operating)
After installation, perform a test cycle to ensure the agitator is functioning correctly. The agitator should rotate freely in one direction and engage to move clothes in the other direction. Listen for any unusual noises.
Maintenance
Agitator dogs are wear-and-tear components. While these replacement parts are designed for durability, their lifespan depends on usage. Regular inspection during other washer maintenance can help identify wear before it causes performance issues. If the agitator begins to slip or not agitate effectively, inspect the agitator dogs for wear and replace them as needed.
Troubleshooting
Agitator Not Moving or Slipping:
- Check Agitator Dogs: Worn or broken agitator dogs are the most common cause of this issue. Re-open the agitator and inspect the dogs. Replace if damaged.
- Proper Seating: Ensure the agitator is fully seated on the shaft and the agitator bolt is tightened correctly.
- Overloading: Avoid overloading the washing machine, as this can put excessive strain on the agitator and its components.
Unusual Noises During Agitation:
- Inspect for Obstructions: Ensure no foreign objects are caught within the agitator mechanism.
- Verify Installation: Double-check that all parts, including the agitator dogs, are installed correctly and securely.
