If all else fails, disconnect the drain hose from the sink/disposal and blow through it. If you can't blow through it, the clog is a solid object (like a piece of glass or a bone)—and you will need to replace the hose.
Before you grab a wrench, try physics.
Dishwasher detergents are excellent at removing grease, but if the water doesn't drain fast enough, that grease cools and solidifies inside the corrugated drain hose. It mixes with: dishwasher pipe clogged

A dishwasher pipe clogged with food, grease, or mineral deposits can halt your kitchen routine, leaving you with standing water and a sink full of dirty plates.
