Water begins to flow when water is poured into the sink.
The dishwasher drain hose is raised by a loop above the level of the bottom of the kitchen sink, ! !!
Therefore, when drained into the sewer, water should not flow into the dishwasher.

The place where the drain connects to the siphon is located below the sewer pipe.
And the dishwasher stinks very much. All filters are clean. The sewer pipes are clean, water easily flows from the sink into the sewer.
