I found this somewhere else. We couldn't get any other fix to work so we decided to try it and see what happened. It worked
We did not do the “making parts" like he does at the end. We just cleaned it out. It surprisingly had some weird stuff in it. It works better than it ever did. We may have to replace it one day, but it's been working for 6 months so far and we saved $120.00.
