Grab the agitator at the base and attempt to rotate it clockwise and counter clock wise. It should remain firmly in place. If there is movement the agitator spline is worn.

This is your Agitator:

It does not come with the fabric dispenser. It has to be ordered seperately. You should be able to transfer you old one to the new one if you do have to replace the agitator.

Besides the agitator the drive bell can also be the source of the noise. It is located under the agitator.

This part is the most likely cause of the noise.

Thanks for using FixYa.
