During the spin cycle, the agitator makes a

If your machine type is a FAV6800AW or FAV9800AW the tumblers or agitator should no rotate in spin cycle maybe a 1/8 turn and no more at the start of spin cycle . If your machine is one of the above machine types maybe you have coins or something under the tumblers. You can remove the tumblers by removing the plastic tumbler caps and with a #20 torx driver. See page 37 for tumbler removal. If your machine type is not the above please disregard my post.

The Service Manual for reference. Sears Parts Direct for reference.

I have another thought but if you could confirm the machine model number that would be helpful. So many folks post non FAV6800AW machine types in this forum.
