Customer Questions and Answers for Upper Agitator by Whirlpool

Hello Johnny. This model does not use the dogs in it. You will need to remove the agitator and see if the splines in the base 21001530 are stripped out. If not, and the agitator is striped and not working, you may have a transmission 35-6615 issue with the unit or a bad thrust bearing 12002213 in the unit.
