Kenmore 655 ultra wash built in dishwasher

Possible problem is that the chopper/cutter filter is plugged. This prevents water circulation and therefor no water is available for cleaning.
Solution:
Remove the dish baskets.
Remove the bottom cleaning arm - Rotate the centre post and the arm can then be removed.
Remove the conduit that feeds the upper arm(s) - Remove screws, one at the back and one at the top. Rotate the whole assembly 45 deg right and lift off of the centre post.
Remove 4 screws in the plastic assembly and lift it off of the centre.
Remove 1 screw at left front (Under assembly just removed). Lift off the plastic cap which covers the cutter/chopper. Remove the chopper. It is on a spring loaded pin. Pull the cutter foreword while lifting the filter disc straight up. Thoroughly clean the filter disc - a knife will be req'd to scrape in clean.
Reassemble in reverse to the disassembly steps.

Anyone have any hints on reassembling the cutter/chopper from Solution 2?

We can't get it back in.

Check the water inlet valve to see if it is getting voltage to it if it is replace the water inlet valve,,,,,,,also check to see that the house water valve for the dishwasher is turned on so water can come into the dishwasher
