Badly smelling crockery after dishwashing

In recent weeks when removing crockery from my integral dishwasher (diplomat, now 5years old) a really bad smell was evident on the sparkling and clean looking crockery. I have used all of the advice available and the Dishwasher was totally clean. Finally gave up and removed it replacing it with a bosch freestanding machine that I purchase around about two years ago. Before installing the bosch all the drainage was hosed and cleaned with “soda cristals” and hose pipe into the ground waste. I still have exactly the same problem, very smelly crockery, sparkling but smelling really bad and offensive. The machine is salted and rinse aid and I use expensive dishwasher tabs can any body help please I am desperate now and don’t know what else to do…thank you
