How to Clean Under the Agitator of a Washing Machine

Unplug the washing machine from the socket where it is currently connected.

Open the hood over the tub and rest it against the control panel.

Examine the top of the agitator. If this agitator has a fabric dispenser on the top, remove this by twisting the dispenser counter-clockwise. Otherwise, the agitator will probably have a cap on top covering the agitator bolt. Pry the top off of the agitator with the edge of a flat-blade screwdriver.

Remove the agitator bolt with a socket wrench and extension, if needed.

Put on a pair of sturdy work gloves. Reach underneath the agitator and grasp it firmly. Pull up on the agitator and slide it up and off the agitator shaft. Set aside.

Clean the part of the tub and agitator hub concealed by the agitator with a standard bathroom cleaner and rag. A nylon brush can be used to get off any stubborn mold or mildew. Clean off the bottom of the agitator while it is out of the machine as well.

Apply a few drops of dish soap to the agitator hub. Slide the agitator back over the hub. Replace the agitator screw and tighten. Replace the cap or fabric dispenser.

Run a short load on the highest temperature setting. Pour 1/4 cup of bleach into the machine to rinse it out and help disinfect after cleaning.
