The spray arm snapped off from the mounting bracket.

First of all, we were very impressed with the ease of finding the parts, the ordering, and the velocity in which the parts were shipped. We received them the next day. I had to remove one of the screws from the old kit, since the new one only came with one. I looked at the diagram on the website of the assembly, and also remembered what the assembly looked like before I took it apart. The first time I tried it, I could not get the spray arm to spin without hitting the dishwasher rack. Since I had ran out of time, I had to wait until the next day. Once I started, I realized that I had the mounting bracket on backwards. Once I turned it around, I tightened the screws, and it was done within 5 minutes.
