I noticed that the upper agitator was free spinning so I googled the problem and found out about agitator dogs. A further parts search brought me to AppliancePartsPros.com, where I was able to find the parts for my Whirlpool washer model and very helpful videos detailing the repair process.
I received the parts within the delivery period chosen at checkout and the washer was repaired in about 1 hour ( I used the short cam kit and went slow putting the agitators back together, making sure that I had the cam inserted the proper side up).
Success. The Washer is working properly and Ingrid ,my wife , now calls me Handyman Ed.
