Understanding the Problem
Admiral top-load washers use an agitator (the tall center spindle inside the tub) to move clothes during the wash. When the agitator slips, grinds, or stops moving, the usual culprits are worn agitator dogs (directional cams), a damaged cam/drive block, a stripped agitator spline, or a broken agitator assembly. Less commonly the problem is the transmission/gearcase, drive coupling, or clutch assembly. Follow these diagnostic and repair steps: 1) Safety first: Unplug the washer and shut off the water supply before working on it. Wear gloves and eye protection. 2) Identify your model number: Locate the model plate (usually under the lid, on the back panel, or behind the control console). You will need this to order correct parts. 3) Observe symptoms in use: Run a short agitate cycle and listen/feel. Note slipping (agitator turns freely), grinding (plastic on plastic noise), or no movement. 4) Check for simple obstructions: Remove clothes and look down the agitator base for small items trapped under or between the agitator and tub. 5) Access the agitator bolt: - Most Admiral/Whirlpool-style agitators have a center cap or fabric softener dispenser on the top of the agitator. Pry off or lift the cap to expose the bolt. - Use the correct socket (commonly 7/16" or 1/2" drive—check your model) and remove the central bolt. If it’s stuck, apply penetrating oil and allow to sit. 6) Remove the upper agitator: - After the bolt is out many upper agitators pull straight up; you may need an agitator puller or a pair of strong hands. If the upper comes off in two pieces (upper/lower), note orientation. 7) Inspect agitator dogs (directional cogs): - These are small plastic one-way pawls inside the top of the agitator. Look for cracked, worn or missing teeth. Worn dogs let the agitator spin one way but slip the other. 8) Inspect the agitator cam / drive block and spline: - Check for stripped or rounded spline teeth on the agitator and on the drive shaft. Inspect any plastic cam or drive block for fractures. 9) Test by hand: With the bot removed, turn the transmission/driveshaft by hand (carefully). If the shaft turns but the agitator does not engage correctly or makes grinding, the dogs/cam or the agitator are likely bad. 10) Replace worn parts: - If dogs are worn: buy an agitator repair kit (dogs + spring + cam if included) specific to your model and replace dogs per kit instructions. - If the cam/drive block is cracked or the spline on the agitator is stripped: replace the cam or the entire agitator assembly as required. - If the driveshaft spline is damaged or you observe metal shavings, the problem may be the transmission/gearcase — this is a major repair and often requires a professional or full gearcase replacement. 11) Reassembly: - Reinstall the lower/upper agitator in the correct orientation, tighten the center bolt to the manufacturer torque spec (hand-tight then follow spec if available), replace the cap. - Run a short test cycle (no clothes, small amount of water) to verify proper agitation and listen for noises. 12) Final check: Verify there is no leaking around the tub or unusual vibration. Safety note: Unplug the washer before disassembly. If you are unsure about removing the cabinet or the transmission, stop and consult a trained appliance technician — gearcase replacement can be heavy and requires correct seals and torque.
Common Symptoms
Agitator spins but clothes don’t tumble properly, washer makes grinding or clicking noises during agitation, agitator slips or turns only one direction, or agitator won’t move at all.
Common Causes
- Worn/broken agitator dogs (directional cogs)
- Cracked or stripped agitator cam/drive block or spline
- Damaged drive shaft spline or transmission/gearcase failure

Helpful Repair Tip
A quick field test: pull up firmly on the upper agitator with the bolt removed. If it lifts and drops freely or the one-way plastic dogs don’t click into place, the dogs (agitator cogs) are almost always worn and need replacement.
Frequently Asked Questions
How do I know if I need to replace just the agitator dogs or the whole agitator?
If the top section of the agitator is loose or moves freely one way and you see small plastic wedges (dogs) inside the top that are rounded or missing teeth, a dog kit typically fixes it. Replace dogs and the cam if cracked. If the spline on the agitator itself is stripped (teeth missing or rounded) or the plastic body is cracked, replace the entire upper agitator assembly.
Can I keep using the washer if the agitator is slipping or making noise?
You can run a cycle occasionally, but continued use may damage the transmission or create more expensive repairs (metal shavings, stripped splines). It’s best to stop using the washer for regular laundry until you replace worn dogs or other damaged parts.
