Black greasy buildup

I own a Maytag dishwasher (MDB6769PAW0) and we keep getting a black/brown greasy like substance built up over a period of time. To realistically keep it clean, I would have to take the inside apart monthly. If I wait longer the buildup can grow quickly.

What I have done so far. I checked to make sure my dishwasher drains. We heat the water in the sink and run the disposal before starting the washing. The dishwasher drain-line is it elevated between the dishwasher and sink. We have tried the two or three in one pods, liquid detergent, powder detergent mixed with lemi-shine. We also use a rinse-aid. The last time I cleaned the dishwasher I pulled everything I could out and cleaned with bleach. I have cleaned the drain line and replaced the feed line. I am still getting slow buildup.

We live in the pacific northwest, we don't have hard water where we live or high humidity. This was never an issue with our last dishwasher. I have replaced the heat element and my dishes come out dry, but there is water on the door and roof of the dishwasher. I have also replaced the food chopper. Before I pay for a service tech, which is about half the cost of a new dishwasher, I am hoping there something I can learn from this forum.

I am including a few photos, which show what the substance looks like. This is an more extreme example of the buildup, we don't let it get this bad anymore.Click image for larger version.  Name: IMG_2350.JPG  Views: 0  Size: 91.5 KB  ID: 38480Click image for larger version.  Name: IMG_2348.JPG  Views: 0  Size: 96.4 KB  ID: 38481Click image for larger version.  Name: IMG_2352.JPG  Views: 0  Size: 154.5 KB  ID: 38482
