Thank you for your question.
I am sorry you are having a problem with the washer. By what you have stated, I suspect the problem with the washer is worn agitator dogs. When the dogs wear down the bottom portion of the agitator will continue to work but the top portion will move intermittently if at all. The image below shows the location of the dogs. The part number of the dogs are 80040 and can be ordered from our parts website:
Sears Parts Direct
To replace the dogs please follow these steps.
Remove the fabric softener dispenser from the top of the agitator.
Remove the agitator cover by pulling it up.
You should see a plastic piece that has a square hole in the center. You need to insert a 1/2 inch drive extension into the hole. Then turn it counter clockwise to remove this retainer.
Remove the cam out of the top portion of the agitator and replace the dogs.
Reassemble the washer in the reverse order and test the operation.
I have provided you with an image below to aid in replacing the dogs. Your model is slightly different from the image but the dogs sit in the cam the same.
Please reply below if you need further assistance.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
