Hello,
If you mean you hear the ticking noise under the agitator while its washing it sounds like the clutch dogs in the agitator are worn. This is not difficult to fix if this is the problem. You have to remove the cap on the agitator and then you'll see a bolt. Remove the bolt and the top of the agitator and the "dogs" are underneath. The agitator would have little or no movement while washing if this is the problem. Hope this helps.
