The bosch dishwasher shx33A continues to drain but is also filling up at the same time. Draining is working as I see it pour into the disposal. Just cant stop water from coming in thru bottom. Had to shut water valve off to stop it.

I had the same problem. The motor had to be replaced. For as much as we paid for this it has not lived up to the Bosch name. It's never been as quiet as other people talk about, and then the motor went out! It's only 2 years old.

Similar problem for us turned out to be water accumulating in the tray which set off the float switch.  I vacuumed the water out and function returned to normal.  However, we are now facing a repairman's assertion the clay in our well clogged the water inlet systems necessitating $285 in repair parts and labor.

I have a guide here to walk you through the process of clearing the drain system. You most likely have a clog somewhere and the dishwasher can't proceed because it would cause it to flood.

Find out where the water is being stopped. Firstly at the wall. Then maybe at the solenoid (depending on the model) and then just trace the water line until you find out where it's being stopped.
Also I would recommend you run some nickel safe ice machine cleaner through the system to get rid of the 'white junk'.
