I agree with tgood, that indicates a fractured spider. The owners manual for this machine is available here:
on pages 21 and 22 it gives the warranty information, the 'inner wash basket' has a 20 year warranty and it does note that client is responsible for the labor charges. It also notes at the top of both pages that "All warranty service provided by our Factory Service Centers, or an authorized Customer Care® technician."
You may be able to get GE to send you the 'wash basket' and fit it yourself but I have my doubts.
I believe it is also likely that the seal and bearings have also failed, a quick way to check this is to remove the rear panel, item 263 in the diagram at the following link:
