kenmore 66517772990 dishwasher checkvalves

I am reinstalling parts for this dishwasher.  It appears to have three check valve balls and not the two I expected.  One is smaller than the other.
In what order do I replace them?

If you have the whole pump disassembled then you'll have three balls the two largest go together as a pair in the main check valve as shown in the link below.

There should only be one check valve (to prevent dishwater from back flow to the water line. But there is also an inlet valve. I think the parts you might want are shown here.
