I have a Bosch Dishwasher Model SHU9925UC/U12 that does not have enough pressure to spin the cleaning wands and it will not pump put the water? Any help? Just a side note. the wife mixed two Cascade dishwashing soaps together and after a few uses this happens. She mixed them in a small easy to use bottle instead of using the large club store bottle to fill the DW with and I noticed that the two (same brand but different name) detergents clumped all up and formed hard white chunks. Of course I hear nothing from Cascade addressing the issues.Thank you for your comments

You will have to trace the water circuit and clean it out. Here are some manuals to help: https://dl.dropboxusercontent.com/u/8010163/Bosch%20Dishwasher%20Sears%20ServiceManual.pdf

I hope this helps. You should remove the arms and clean them, too.
