Spinner Fell Off in Dishwasher

There is a plastic part in the dishwasher that looks like a hurricane symbol. It's called a Spinner and it disperses water during the wash and rinse cycles. It is located on the top of the inside of the dishwasher. Unfortunately there is a small plastic part that holds the Spinner in place. This plastic part wears out after a few years and requires replacement. I have replaced it twice - part number 8519736. Very easy to replace - unscrew one screw and put in the part (three separate component) - obvious how it works. Good luck.
