Thanks for the link and went through the manual looking for the magic key, no luck. Models don't match. At one point in searching for the answer I came accross a manual that had close model number and it looked right however the magic key was not listed any where I could find. Does anyone know if the piece just lifts off and it's stuck on mine? I could always use the hammer answer but I didn't want to break it or the lower housing causing more issues/problems.
Just trying to solve the no water making it to upper arm issue. Already cleaned out arms and other lead tubes. Even cleaned the part of the chopper screen I could get to with small brush. No luck for the water fix. Perhaps it's a diifernt issue anyhow and I don't need to remove it?
