The upper agitator was moving freely and an obvious repair was needed.. A simple search revealed the part needed, (dogs) I decided to replace a few other parts as well.. (dust cap seal, agitator dog assembly/kit, though the cap itself wasn't needed, nor the dog assembly as they were in good condition but the minimal price difference determined my purchase) I still did laundry while waiting for the part, not a big deal in my mind, just perhaps slightly less efficient but not a detriment to the cloths.. A single bolt holds everything together and it couldn't be easier to access the damaged part. ***If you have the model with the 4 white tabs holding the upper and lower agitators together, don't worry so much about them.. 2 will likely break even though I used a small flat screwdriver to pry them back a little.. mine were melted/fused from manufacturing, but the bolt and washer will hold everything together when you reassemble..*** It took me 3 times longer to clean the parts than it did to simply replace the part, but take the time to clean the agitators, now is your opportunity and you will feel good looking at bright clean agitators for many loads to come.. The new dust cap was actually a slightly thicker plastic than the original so the fabric softener cap wouldn't click into place, not a big deal (I ended up using the original cap with the new seal) As soon as I assembled the parts I could feel the new dogs working which resulted in a nice money saving smile!.. Reassembled the agitator stack and began testing it out.. Finding the parts I needed, instructional videos, and online chat help is why I love APP and fixing my own equipment.. This is one repair that may seem more complicated than it actually is.. you can do it!!..
