When your top-load washer's agitator stops working properly, worn agitator dogs are usually the problem. These plastic components enable the agitator to move clothes during wash cycles. If your agitator isn't rotating correctly or slips during operation, replacing the agitator dogs will restore performance. This guide from AZParts covers the complete replacement process, from safely shutting down your washer to testing the repair.
1. How to Replace the Agitator Dogs on a Top-Load Washer
Replacing agitator dogs is a straightforward repair that most homeowners can complete with basic tools and careful attention to safety procedures. The entire process typically takes 30 to 60 minutes, depending on your washer model and experience level.
1.1. Shut Off the Electricity

Safety should always be your top priority when working on any electrical appliances. Before beginning any repair work on your washing machine, you must completely disconnect it from its power source to prevent accidental startup or electrical shock hazards.
Unplug the washer from the wall outlet. If hardwired or the outlet is hard to reach, switch the circuit breaker to OFF. Take a moment to verify that the power is completely disconnected by attempting to turn on the washer - nothing should happen when you press the power button.
For added safety, tape over the breaker or cord with a repair note. This prevents accidental power restoration while working. Wait 10 minutes after disconnecting power to let residual charge dissipate.
Check that the water supply valves are also turned off, though this step isn't strictly necessary for agitator dog replacement. Having both water and electrical systems secured provides the safest working environment and prevents any unexpected surprises during the repair process.
1.2. Remove the Agitator

Most top-load washers have agitators that can be removed by hand or with basic tools, though the exact method varies by manufacturer and model. Begin by examining your agitator to determine the removal method required for your specific washer.
Many agitators have a decorative cap or fabric softener dispenser at the top that must be removed first. Gently lift or twist off this cap to reveal the agitator's mounting hardware. Some caps simply lift off, while others require a counterclockwise twist. If resistance is encountered, you should not force it then consult your washer's manual for the correct removal procedure.
Once the cap is removed, you'll typically find either a bolt, nut, or cam that secures the agitator to the drive shaft. For bolt-secured agitators, use an appropriate socket wrench to remove the mounting bolt by turning counterclockwise. Some models use a cam mechanism that requires pulling straight up while others need a specific twist-and-lift motion.
If your agitator seems stuck, avoid using excessive force as this can damage the drive shaft or agitator components. Instead, try gently rocking the agitator back and forth while pulling upward, or apply penetrating oil around the base and allow it to work for several minutes before attempting removal again.
1.3. Remove the Agitator Dogs

Access the agitator dogs:
- With the agitator removed from the washer, you can access the agitator dogs located in the lower portion of the agitator assembly.
- They are typically arranged in a circular pattern around the interior base section.
Inspect the bottom of the agitator:
- Turn the agitator upside down on a clean work surface.
- Look through the bottom opening to locate the plastic agitator dogs positioned around the perimeter.
- They may be secured by springs, clips, or held in place by friction.
Remove the agitator dogs:
- Carefully lift each dog straight out of its slot.
- Some models may require compressing a small spring or releasing a retaining clip before removal.
- Take note of each dog’s orientation and position for proper reinstallation.
Inspect the old agitator dogs:
- Check for signs of wear, cracking, or damage.
- Common issues include rounded edges, visible cracks, or missing pieces.
- Even if only one or two are worn, it’s best to replace the entire set for balanced performance.
Clean the housing area:
- Thoroughly clean the agitator dog housing to remove debris, soap scum, and mineral deposits.
- Use a small brush or cloth to scrub away any stubborn buildup.
1.4. Install the New Agitator Dogs

Installing new agitator dogs requires careful attention to proper orientation and positioning to ensure optimal washer performance. Quality replacement parts make a significant difference in longevity and operation, so choosing reliable components is essential for a successful repair.
If you're looking for reliable agitator dogs, AZParts has you covered with our extensive selection of genuine washer parts including high-quality agitator dogs designed for various washer brands and models.
Begin by examining the new agitator dogs to familiarize yourself with their shape and any directional features. Most dogs have a specific orientation that must be maintained for proper engagement with the drive mechanism. Compare the new parts with the old ones to ensure you have the correct replacements for your washer model.
Insert each new agitator dog into its corresponding housing slot, ensuring it seats completely and moves freely within its designated space. The dogs should fit snugly but not bind or stick when moved by hand. If springs or retaining clips are part of the design, make sure these components are properly installed and functioning correctly.
Test the movement of each newly installed dog by gently pressing on it to verify smooth operation. The dogs should move easily in their intended direction while returning to their original position when pressure is released. Any binding or irregular movement indicates improper installation that should be corrected before proceeding.
Double-check that all dogs are properly oriented and seated before moving to the next step. Incorrect installation can result in poor agitator performance, excessive wear, or damage to other washer components during operation.
1.5. Reinstall the Agitator

Reinstall the agitator assembly:
- With the new agitator dogs installed, begin reassembling the agitator into the washing machine.
- This process is the reverse of removal, but careful alignment is essential.
Align and seat the agitator:
- Position the agitator over the drive shaft, aligning its internal components with the drive mechanism.
- It should slide down smoothly—do not force it.
- If resistance is felt, remove and check for misalignment or obstructions.
Secure the agitator:
- Reinstall any mounting hardware removed earlier.
- For bolt-secured models: thread the bolt clockwise until snug. Avoid overtightening to prevent damage.
- For cam-type mechanisms: lock the agitator in place with the correct twist or push motion.
Reinstall additional components:
- Replace any washers, spacers, or other small parts in their original positions and orientations.
- These components are important for proper agitator performance.
Reattach top cap or dispenser:
- Reinstall the decorative cap or fabric softener dispenser.
- Ensure it is properly seated and secure.
- If it includes moving parts, test the mechanism to confirm it functions correctly.
1.6. Restore the Power

After completing the agitator dog replacement and reassembly, it's time to restore power to your washing machine and test the repair. This final step verifies that your work was successful and identifies any issues that may need additional attention.
Reconnect the washing machine to its power source by plugging it back into the wall outlet or switching the circuit breaker to the ON position. Remove any safety tape or notes you may have placed during the repair process.
Turn on the washing machine and run a short test cycle to verify proper agitator operation. Start with a small load or run an empty cycle to observe the agitator's movement and listen for any unusual noises that might indicate installation problems.
The agitator should rotate smoothly in both directions during the wash cycle, with no slipping, binding, or irregular movement. Pay attention to the sound of the operation - it should be similar to the washer's normal operation before the agitator dogs failed.
If you notice any problems during the test cycle, immediately stop the machine and recheck your installation. Common issues include improperly seated agitator dogs, incorrect agitator mounting, or failure to properly reconnect internal components.
2. Do All Washing Machines Have Agitator Dogs?

Not all washing machines use agitator dogs, as washer design varies significantly between manufacturers and models. Understanding which types of washers use these components helps you determine whether this repair applies to your specific appliance:
- Traditional top-load washers with dual-action agitators commonly use agitator dogs to enable the reversing motion that provides effective cleaning action. These washers feature tall, central agitators that move clothes through the wash water using a back-and-forth twisting motion powered by the agitator dogs' directional engagement system.
- Single-direction agitator washers typically don't use agitator dogs, instead relying on continuous rotation in one direction throughout the wash cycle. These systems use different mechanisms to achieve clothes movement and cleaning action, making agitator dog replacement unnecessary for this washer type.
- High-efficiency top-load washers often feature impellers instead of traditional agitators, eliminating the need for agitator dogs entirely. These washers use low-profile wash baskets and specialized wash action to clean clothes while using less water and energy than conventional designs.
- Front-loading washing machines don't use agitators at all, instead relying on gravity and drum rotation to move clothes through the wash solution. These washers achieve excellent cleaning performance without any agitator-related components that might require replacement or maintenance.
- Some newer top-load models feature hybrid designs that combine elements of traditional agitators with modern efficiency improvements. These washers may or may not use agitator dogs depending on their specific design and manufacturer specifications.
If you're unsure whether your washing machine uses agitator dogs, consult your owner's manual or contact the manufacturer for clarification. You can also examine your agitator by removing the top cap - if you see a circular arrangement of small plastic components around the base, your washer likely uses agitator dogs that may eventually require replacement.
Replacing agitator dogs is a cost-effective repair that can restore your top-load washing machine's cleaning performance and extend its operational life. By following this comprehensive guide and using quality replacement parts, you can complete this repair confidently and achieve professional-quality results.
Remember that proper diagnosis, careful attention to safety procedures, and using genuine replacement parts are essential for successful repairs. Don't hesitate to consult with professionals if you encounter unexpected complications or feel uncertain about any aspect of the replacement process.
