Standing water in the drain pipe between the air gap and I presume the bottom of the loop at the back of the machine is not good. Maybe a little but not all the way to the top of the pipe.
There will be no draining back of the water into the machine as there is a check valve that diverts the dirty wash water to the drain pump but prevents it coming back into the machine itself
You said that you checked the drain hose for clogs etc but maybe you need to check the drain pump itself (as best you can) to see if the pump is OK and not clogged (maybe where the smell is coming from?) or perhaps the impeller blades may be broken or slipping reducing the pressure of the flow through the pump.

Here’s the [document|25585|tech sheet] for the dishwasher which may also help. On the lower half, left side, it describes how to get into the diagnostic mode so that all the functions of the dishwasher can be tested. (Sometimes the tech sheet can be found behind the kick plate (toe plate?) in a plastic sleeve as well)

If it is determined that the pump is the problem there are other suppliers online that may suit you better. just search for ''KUDS02FRSS4 parts'' to get results.
