Yes you can pop the top of the agitator off which is the softener dispenser. To remove the bottom part of the agitator you need to remove the bolt on the center. Here is a parts breakdown http://lookup.bellparts.com/diagramenlarge/2/0/525481/87051 Also if it is just an odor from soap build up or mold you can run two Affresh tablets through the machine on a heavy duty cycle set on hot water. These will break up the build up and not just mask it. You can find the Affresh tablets at any store or online.
