Hello, Thank you for using this service, I will be helping you with your problem today
good afternoon, these agitator come off the drive bell. the best thing to do is pull the whole agitator off and take out side and use a spray hose to rinse it good. this is the drive bell. this is connected to the transmission shaft, the agitator snaps onto this.you need to get your hands underneath one each side of the agitator and pull up with force. these can be really tight but do pop off. (be careful you don't strike yourself in the face) once its out clean it real good with a hose. as far as the dispenser is the part broken ?
