Problem Solved ! Like most here, My new Bosch dishwasher (7-2021) cheapest one ) smells bad Checked the drain hose.. nothing wrong Checked the screen ...Clean as new.. I always pre-rinse my dishes even though they say not to ???? Ran Vinegar through it to kill any mold.. still not right. Then I studied the smell and thought it smelled like the small packages of soap you are supposed to use Hooray ! The soap makes it stink. I went back to Cascade powder soap and Wallah. NO SMELL ! its there recommended soap packages !

Brand new Bosch 100 Dishwasher ran it with the sterilize cycle first , then put a load of pre rinsed dishes in and Cascade packet (2) and had Finish tank filled The smell came with the first load.. New drain line, with tall loop so no backfeed There is something wrong folks ! Brand new and it stinks ! Never had that with my Kenmores or Amana’s - In 30 years I never had to “clean” the dishwashers . My screens have always been perfectly clean I am not a washing machine expert, but I do know metals and I suspect that the stainless steel is treated somehow and that reacts with detergent ? Looks like Bosch has some explaining to do !
