Thanks for using FixYa. First of all please check the Water temperature by using a thermometer inside the dishwasher to measure the water temp. It should be as close to 125 degree F to 140 degree F as possible. Now try using the temperature boost feature if your dishwasher is equipped with this cycle feature and check if this will help your wash ability issues.
Now check the Powder soap by making sure that you store your soap in a dry environment and it is not stale and clumping together. Possibly try a different detergent like a liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is not overloaded.
To check the proper filling dishwasher will fill with water up to and around the heating element. If water is more below the heating element, you may have low water pressure or a problem with the fill valve. Try & listen if it sounds like it is spraying the water around with enough pressure.
For low water pressure, try to clean the screen at the entrance of the fill valve, sometimes the fill valve can fail and not allow the proper water into the dishwasher and may need to be replaced. And, check the spray arm and pump cover for splits or leaks. Also make sure that the water is draining and is not accumulated in the dishwasher, if it is in dishwasher then check for clogged drain hoses and drain pump.
Low water fills are a very common trouble maker with today's dishwasher.
Please do rate this solution and revert for further assistance.

We have a Kenmore 665.17702k600 Portable dishwasher with a similar problem. What we did was pop off the drain cover (turns out the one screw wasn't doing anything and just pushed down into the unit when screwdriver was applied). We popped it off by shimmying a screwdriver under the panel, and applying torque on the long end. It just popped right off. Then there was this nasty stale water, and not much obvious debri. We used a wet vac to slurp all that up. So that's the solution we took -- haven't tried it yet, so not sure if it will actually fix the problem...

Most dishwashers have a soil separator which separates the soil from the water while it's washing. When a wash cycle is over a valve opens in the separator to allow the soil to go down the drain. If it's not working properly the washer will leave a film or food particles on the dishes.
It's under the lower spray arm. Post your model number and I may can find a diagram for you. Dishwasher- Inside the doorjamb on the top, left or right. On the door edge top left or right. Portable models on the back.
