My Maytag MDB7160AWB washer started not cleaning very well a few weeks ago, food would be left on dishes, etc. I confirmed the water is hot, water gets in to the washer, it sounds like it is filling, running and draining, but the dishes are still dirty. I did test the resistance of the inlet valve and it’s not an open circuit but it is reading 1000 ohms. Is that the problem then, or is that normal for that inlet valve?
Sounds like there is a problem with the wash pump. If the dishwasher is less than five years old - it is still under the limited manufacturer warranty and it’s better if you call Maytag for service.
