How do you get dirty water out of a dishwasher if it won't drain? - used dishwasher parts

I tested the immersion in water with a very small glass. There are parts on the floor, and I can not access any water or dirt. I have a vacuum cleaner. I do not use the dishwasher is old and nevertheless. I only get water.
