Agitator Dog Repair Kit — Complete Guide for Whirlpool WTW5000DW Top-Load Washer
The agitator dogs (also called drive pawls or agitator dogs) on your Whirlpool WTW5000DW are small plastic components located inside the agitator that engage with the drive block during the wash cycle. When these dogs wear out or break, the agitator will fail to turn properly during washing, leaving your clothes dirty and tangled. This repair addresses the root cause of agitator failure on this popular top-load model. The agitator dog repair kit (part 285811 or equivalent 80040) contains replacement dogs that restore proper agitator engagement. Difficulty Level: MODERATE — This repair requires partial disassembly of the washer tub assembly but is accessible to DIY technicians with basic mechanical aptitude.
Symptoms
- Agitator does not turn or rotates only intermittently during the wash cycle on your Whirlpool WTW5000DW
- Clothes remain bunched around the agitator center column with minimal movement
- Audible grinding or clicking noise coming from inside the tub during the agitation phase
- Agitator spins freely by hand with no resistance or engagement (indicating missing or broken dogs)
- Clothes are excessively wrinkled or tangled after a wash cycle due to lack of agitation
- Water drains but the drum stops moving mid-cycle on the Whirlpool WTW5000DW
⚠️ Safety Warning
- Unplug the washer completely from the electrical outlet before beginning any disassembly work on your Whirlpool WTW5000DW. Do not rely on the power button alone.
- Shut off both hot and cold water supply valves behind the washer to prevent water spillage during disassembly.
- The washer lid is heavy and can cause injury. Support it with one hand or prop it open carefully using a sturdy object. Do not let it fall freely.
- The agitator cap may have sharp edges after removal. Handle with care and inspect for burrs before reassembly.
- Allow the washer to cool for 10–15 minutes after a wash cycle before disassembly, as internal components may retain heat.
- Keep your hands and fingers clear of pinch points when removing the agitator assembly from the Whirlpool WTW5000DW tub.
Parts Needed
- Agitator Dog Repair Kit — Part 285811 (primary part for Whirlpool WTW5000DW; contains 4 replacement drive dogs/pawls)
- Alternative Part Number: 80040 (equivalent agitator dog set for some Whirlpool top-load models; verify compatibility with your WTW5000DW before ordering)

- Towels or absorbent cloths (to catch residual water when opening the tub)
- Small container (to organize and store small screws and springs during disassembly)
Step-by-Step Instructions
Step 1: Prepare the Washer and Create a Safe Work Area
Unplug your Whirlpool WTW5000DW from the electrical outlet and wait 5 minutes to allow residual electrical charge to dissipate. Turn off both the hot and cold water shut-off valves located behind the washer. Lay towels on the floor around the washer base to catch any water that may spill during disassembly. Open the washer lid fully and inspect the interior tub for any visible debris, lint, or foreign objects that should be removed first. This prep work ensures your safety and makes the repair process cleaner and more efficient.
Step 2: Remove the Agitator Cap from the Whirlpool WTW5000DW
Locate the agitator cap at the top center of the agitator column. On the Whirlpool WTW5000DW, the cap is secured with two Phillips head screws positioned at the 10 o’clock and 2 o’clock positions when viewed from above. Using your Phillips head screwdriver, carefully remove both screws and place them in your small container. Gently pry upward on the agitator cap using a plastic pry tool or flat-head screwdriver inserted at the edge near the seam. Avoid forcing the cap, as the plastic threads can crack. The cap should lift free once the screws are removed. Set the cap aside in a safe location.
Step 3: Disconnect the Drive Block Spring and Retaining Clip
With the agitator cap removed, you will see the drive block assembly inside the agitator column on your Whirlpool WTW5000DW. A tension spring is connected to the drive block, typically positioned at the 6 o’clock position. Using needle-nose pliers, carefully unhook the spring from its attachment point on the drive block. Next, locate the metal retaining clip (U-shaped or C-shaped) that holds the drive block in place. Gently pry this clip upward and to the side using your needle-nose pliers or plastic pry tool until it releases from its groove. Be careful not to bend the clip excessively, as it will need to be reused during reassembly.
Step 4: Remove the Drive Block Assembly from the Agitator
Lift the drive block assembly straight upward out of the agitator column on the Whirlpool WTW5000DW. The drive block is a cylindrical component with four recessed pockets or slots where the agitator dogs sit. Once the drive block is removed, you will have clear access to the four agitator dogs (drive pawls) that are installed in the agitator itself. Set the drive block on a clean surface where it will not be damaged during the dog replacement process.
Step 5: Inspect the Worn or Broken Agitator Dogs on the Whirlpool WTW5000DW
Examine the four agitator dogs that remain in the agitator column. These are small, flat plastic pieces, typically gray or black in color, positioned at 12, 3, 6, and 9 o’clock positions around the interior of the agitator. Look for cracks, splits, worn edges, or pieces that are completely broken away. On the Whirlpool WTW5000DW, worn dogs will have rounded or flattened engagement surfaces where they previously contacted the drive block. Take a photograph if helpful for reference. In most cases, all four dogs should be replaced simultaneously using your agitator dog repair kit (part 285811) to ensure balanced operation and prevent premature re-failure.
Step 6: Remove the Old Agitator Dogs
Each agitator dog on the Whirlpool WTW5000DW is typically held in place by a small spring or snap fit. Using your needle-nose pliers, gently compress or lift the retaining spring that holds the first dog in position. Slowly slide the worn dog out of its slot. Repeat this process for the remaining three dogs, working around the agitator in a clockwise pattern. Place the old dogs in your parts container. If a dog is broken and fragments remain, use your pliers to carefully remove all pieces. Clean out any plastic debris from the dog slots using a dry cloth and flashlight to ensure full visibility.
Step 7: Install the New Agitator Dogs from the Repair Kit (Part 285811)
Remove the four new agitator dogs from your repair kit (part 285811). Inspect each dog to ensure it matches the slot dimensions and that the engagement surface (the side that contacts the drive block) is smooth and undamaged. Starting at the 12 o’clock position on the Whirlpool WTW5000DW, slide the first new dog into its slot until it seats fully against the interior surface. Secure the dog by compressing and seating its retaining spring or snap feature. You should hear a subtle click or feel the dog lock into place. Repeat for the remaining three new dogs at 3, 6, and 9 o’clock positions. All four dogs must be installed with their engagement surfaces facing inward toward the center of the agitator.
Step 8: Reinstall the Drive Block Assembly
Carefully lower the drive block assembly back into the agitator column on your Whirlpool WTW5000DW, aligning it so the four recessed pockets on the drive block align with the four new agitator dogs. The drive block should slide down smoothly. Once fully seated, reinstall the metal retaining clip by pushing it down and to the side into its groove until it locks in place. The clip should sit flush and secure. Reconnect the tension spring to the drive block at the 6 o’clock position, ensuring the spring is under slight tension but not overstretched. Manually rotate the agitator by hand—it should turn smoothly with moderate resistance, and the drive block should engage without grinding or clicking sounds.
Step 9: Reinstall the Agitator Cap
Place the agitator cap back onto the top of the agitator column on the Whirlpool WTW5000DW, aligning the two screw holes with the corresponding threaded holes in the column. Hand-thread the two Phillips head screws first to ensure proper alignment and to avoid cross-threading the plastic inserts. Once hand-tight, use your Phillips head screwdriver to tighten both screws firmly but not excessively—over-tightening can crack the plastic cap. The screws should be snug enough that the cap does not wobble, but not so tight that you feel significant resistance. The typical torque is approximately 5–7 inch-pounds, which is moderate hand-pressure.
Step 10: Reconnect Water Supply and Plug in the Whirlpool WTW5000DW
Turn both the hot and cold water supply valves back on behind the washer, opening them fully. Listen for any water leaks around the valve connections. Turn the washer back on by plugging it into the electrical outlet. Allow the washer to sit for 1–2 minutes to re-pressurize the water lines before running a test cycle.
Step 11: Run a Test Wash Cycle
Close the washer lid on your Whirlpool WTW5000DW and set it to run a normal wash cycle with a small load (6–8 towels) and warm water. Allow the cycle to reach the agitation phase. Listen and observe through the lid (if visible) or by opening it briefly to confirm that the agitator is now turning smoothly and continuously throughout the agitation phase. There should be no grinding, clicking, or hesitation. The clothes should be actively moved around the tub by the agitator motion. If the agitator turns properly, allow the cycle to complete.
Step 12: Final Inspection and Documentation
Once the test cycle completes on your Whirlpool WTW5000DW, run one additional full cycle with a normal load to confirm sustained operation. Check beneath and around the washer for any water leaks that might indicate a problem with reassembly. Verify that the agitator cap remains tight and secure. Document the repair date and part numbers (285811 for future reference. If all systems are operating normally, the repair is complete and the washer is ready for regular use.
Troubleshooting
- Agitator still does not turn after repair: The new dogs may not be fully seated in their slots. Disassemble again and verify each dog is locked into place with its retaining spring secure. Check that the drive block pocket surfaces are clean and undamaged; if grooved or worn, the drive block (part 285756) may need replacement.
- Grinding or clicking noise continues: Inspect the drive block bottom surface and agitator dog engagement surfaces for cracks or chips. A cracked drive block will require replacement (part 285756). Ensure all four dogs are installed and no fragments remain in the slots.
- Agitator cap is loose or wobbles: Remove the cap and hand-thread the two securing screws again, checking for cross-threading. If threads are stripped, the agitator may require replacement or the threaded inserts may need repair.
- Water leaks from the agitator area during operation: The agitator cap seal (part 3957764) may be damaged or improperly seated. Disassemble, inspect the seal, and replace if cracked or hardened. Ensure the cap is centered before tightening.
- Clothes still not moving after agitator spins: Confirm the agitator is actually turning by manually rotating it before reassembly and after repair. If it turns smoothly but clothes are still stationary, the issue may be unrelated to the agitator dogs (check for a clogged drain or transmission issue).
- Dogs wear out again after a few months on the Whirlpool WTW5000DW: Premature wear indicates a binding drive block or misalignment. Verify the agitator shaft is straight and not bent. Check that the tub bearing at the base of the agitator is not seized, as this will cause excessive resistance and accelerate dog wear.
When to Call a Professional
- If the drive block itself is cracked, chipped, or shows deep groove wear that prevents the new dogs from seating properly, a professional should inspect the transmission coupling and tub bearing on your Whirlpool WTW5000DW to rule out mechanical binding that caused the damage.
- If water leaks persistently from around the agitator area or from beneath the washer after reassembly, a professional should verify that all seals and gaskets are correctly installed and that the t

The Agitator Dog Kit That Actually Stops Your WTW5000DW From Slipping
If your agitator is spinning freely without gripping the wash basket, worn-out dogs are almost always the culprit—and this OEM kit is the direct replacement that matches your model’s specifications exactly. Skip the universal kits for this one; Whirlpool engineered these dogs to work with this specific drive block geometry.
What works
- Genuine Whirlpool part (285811) means the dogs fit the drive block engagement teeth without gaps or binding—I’ve seen universal replacements cause grinding noise or fail to engage halfway through a cycle.
- Comes as a complete kit with all four dogs and the spring clip, so you’re not hunting for individual parts or making a second order when you realize you’re missing hardware.
- Installation is straightforward once the agitator is removed—dogs simply slide into the slots on the drive block with no modification needed, and the job takes maybe 10 minutes total.
What doesn’t
- This is a direct fit for WTW5000DW only—if you own a different Whirlpool model, check the part number first because mixing model-specific dogs will leave you with an agitator that either won’t turn or grinds constantly.
- Doesn’t address damage to the drive block itself—if the block teeth are stripped or cracked, new dogs won’t solve the slipping problem, and you’ll waste time on a part that can’t grip damaged metal.
The friction point I hit on my first WTW5000DW repair was assuming the agitator seal was the problem when the real issue was worn dogs—I replaced the seal first and wasted a day before pulling the agitator and seeing the dogs worn down to nubs. Once I had the right diagnosis, ordering the Whirlpool 285811 Agitator Dog Kit solved it in one repair cycle.
