The bottom rinse arm of my Fisher and Paykel 913T dishwasher has fallen off the spindle and will no longer rotate. Obviously some part has disintegrated and needs to be replaced -- whatever it is should be anchoring the rotating arm on the spindle above and below. What is the part?

There is a two part plastic piece which will be your problem. The top part is a cap which you can undo by turning all the way left and lifting. The bottom part has the thread on it which screws onto the spindle. If you look at the other arm you should be able to see exactly what it is and how it works. the to parts are identical.
