Understanding the Problem
What the agitator does: The agitator is the central post in a top-load Maytag washer that moves back-and-forth to move clothes through the wash water. When the agitator or its components fail you can get no agitation, slipping, grinding noises, excessive vibration, or clothing that’s not getting clean. Step-by-step diagnostic and repair steps: 1) Confirm symptoms and identify affected part: Is the washer spinning fine but not agitating (wash cycle), or is the entire drum not turning? If spin works but agitation does not, the problem is usually the agitator assembly (dogs/cogs, cam, splines) or the agitator bolt. If nothing turns at all it may be the drive coupling, belt/gearcase, or motor. 2) Locate your model and get parts: Find the washer model/tag (inside the cabinet, behind the control panel or on the back). Order the correct agitator assembly or repair kit for your specific model. Many parts vary by model/year. 3) Unplug and shut off water: Always disconnect power and turn off water (if you need to move the washer). 4) Remove fabric softener/dispenser cap: Pry off the softener cap in the top of the agitator (if present) with a flat screwdriver. 5) Remove agitator cap and access bolt: Pull up the agitator cap (or use screwdriver to release tabs) to expose the retaining bolt. Some models have a plastic cap; others have a center post cover. 6) Remove the retaining bolt: Use the correct socket or deep socket (commonly 3/8" or 7/16" depending on model) to remove the bolt holding the agitator to the drive shaft. You may need to hold the inner basket so the bolt doesn’t turn (rotate the spin cycle by hand to lock). 7) Pull the agitator off the shaft: The agitator may lift straight up. If it’s stuck, rock it back and forth; do not pry on the outer tub. Inspect the bottom of the agitator and the top of the drive shaft. 8) Inspect parts: Check for broken or missing agitator dogs (small plastic pawls), worn or stripped splines on both the agitator and the drive shaft, cracked cam, damaged agitator bolt/washer, and any debris. Also inspect the drive coupling or transmission top if agitation failures persist. 9) Replace the failed component: If dogs/cogs are worn or missing, install a dogs/cogs repair kit (often includes the cam). If splines on the agitator are stripped, replace the entire agitator assembly. If the drive shaft splines are damaged, the transmission/gearcase or coupler may be required. 10) Reassemble: Seat the new or repaired agitator onto the splined shaft, reinstall the retaining bolt with proper torque (hand-tight then snug with socket), snap caps back in place, and test with a short wash cycle. 11) Test and verify: With the washer reassembled and powered, run a small load to verify proper agitation, listening for grinding, slipping, or unusual vibration. How to fix (practical tips): Use the OEM repair kit when possible—these kits typically include dogs/cogs, seals and the cam, and are inexpensive compared to a new agitator. If the lower agitator housing is cracked or splines are shredded, replace the full agitator assembly. If the drive shaft or coupling is scored, replace the coupling or inspect the transmission. Safety note: Always unplug the washer before working on it. Support any heavy parts and avoid reaching into the wash basket while the machine is powered. If the repair involves the transmission or inner tub disassembly, consider professional help unless you have mechanical experience.

Helpful Repair Tip
Confirm the faulty part by removing the agitator and doing a manual spin: if the drive shaft turns freely but the agitator dogs are worn or missing, the wash action will be lost. Also inspect for shredded splines — if splines are stripped you’ll need the full agitator or coupler replaced.
Frequently Asked Questions
How do I know if I need a full agitator replacement or just the agitator dogs?
Remove the agitator and inspect the underside: if small plastic pawls (dogs) are missing, worn or not biting, a dogs/cam repair kit will usually fix the problem. If the plastic splines on the agitator itself are rounded or shredded, replace the full agitator assembly. If the metal drive shaft splines are damaged, the issue may be the transmission or drive coupling and will require additional parts.
Can I replace the agitator myself, and what tools do I need?
Yes — most top-load Maytag agitator repairs are DIY-friendly. Basic tools: socket set (deep socket that fits the retaining bolt), ratchet, flat screwdriver, pliers, and possibly a small pry bar. Always unplug the washer first. If the repair requires dropping the inner tub, removing the transmission, or replacing the drive coupling, you may want a service manual or a professional technician.
