Setup and Installation
Replacing the agitator dogs typically involves accessing the agitator assembly within the washing machine. The following steps provide a general guide. Specific washer models may vary slightly.
Tools You May Need:
- Screwdriver (Phillips or flathead, depending on your washer model)
- Socket wrench (if agitator bolt is present)
- Pliers (optional, for stubborn parts)
Installation Steps:
- Disconnect Power: Unplug the washing machine from the electrical outlet. Turn off the water supply valves.
- Access the Agitator:
- For most top-load washers, you will need to remove the fabric softener dispenser or cap from the top of the agitator.
- Locate the agitator bolt (if present) at the bottom of the agitator. Use a socket wrench to remove it.
- Carefully pull the upper agitator section straight up and off the agitator shaft. This may require some force.
- Remove Old Agitator Dogs:
- Once the upper agitator is removed, you will see a cam assembly and the old agitator dogs.
- The old agitator dogs are typically small plastic pieces that sit in slots around the cam. Carefully remove the worn or broken agitator dogs.

- Install New Agitator Dogs:
- Insert the new UpStart Components 80040 Washer Agitator Dogs into the designated slots on the agitator cam. Ensure they are seated correctly and facing the proper direction (refer to your washer's service manual if unsure).
- Typically, there are four agitator dogs. Replace all of them for optimal performance.
- Reassemble the Agitator:
- Carefully place the upper agitator section back onto the agitator shaft, aligning it properly.
- If an agitator bolt was removed, reinsert and tighten it securely.
- Replace the fabric softener dispenser or cap.
- Reconnect Power: Plug the washing machine back into the electrical outlet and turn on the water supply.
- Test Operation: Run a small test cycle to ensure the agitator is functioning correctly.
Operating Instructions
After successful installation of the new agitator dogs, your washing machine's agitator should now engage and rotate properly during wash cycles. No special operating procedures are required beyond the normal use of your washing machine. If the agitator does not move or clothes are not cleaning effectively, refer to the Troubleshooting section.
Maintenance
The UpStart Components 80040 Washer Agitator Dogs are designed for durability. Regular maintenance of the agitator dogs themselves is not typically required. However, to ensure the longevity of your washing machine and its components:
- Avoid overloading the washing machine, as this can put excessive strain on the agitator and its components.
- Ensure that no foreign objects (e.g., coins, small toys) are left in clothing pockets, as these can damage the agitator or tub.
- If you notice any unusual noises or a decrease in agitator performance, inspect the agitator dogs for wear or damage.
