Our DU930PWP dishwasher (which was in our house when we moved in, last year) no longer cleans dishes well on the Regular cycle. We have to use the Heavy cycle. Even that regularly leaves dishes with stuck-on food bits. Silverware has the worst time - about 30% comes out of the basket with food still on it.
Possibly unrelated, but the dishes on the top shelf often have pools of nasty water still in them after a full cycle.
Thanks for the clarification (we get a lot of people on here that don't know how to really use a dishwasher).
Sounds to me like the DW may need a through going over.
Confirm the make and model of the DW so I can see how it's built. I am suspect that with all the food particles and film you mention, that the spray heads are clogged in the spray bars, and, check that the drain hose is not kinked, and it's attachment into the garbage disposal is clear. I've had these clog before, limiting the ability of the DW to get rid of the dirty water.
Testimonial: "Thanks! I'll try these and check back in after the holidays."
I found exploded views, and I might add, my daughter and son-in-law have one of these and it does a pretty good job of cleaning dishes.
Take the baskets out, take the spray bars out and make sure they are clean of foodstuffs. Remove the bottom filter assembly (larger round plastic ring) and look for accumulated foodstuffs.
And again, check for a kinked drain hose and clogged or partially clogged disposal connection, as well as sink drain capability. (My DW recently began having a similar problem, combined with taking forever to complete the cycle because it couldn't drain, and I found the drain was partially clogged.
Let me know what you find.

Hi,
The scum, film and white
residue problems have started since the reduction of
phosphates in dishwasher detergents.
Here is a tip that
will help you to solve the problem of films, residue, and scum in
your dishwasher.

We are rinsing dishes before they go into the dishwasher. There is not large amounts of food on the dishes - those gets put in the garbage. Sometimes there are pieces of food remaining in the washer, and sometimes there is a baked-on film of unwashed food. We don't use the heated dry setting.
The pools of nasty water form on the bottoms of the glasses/bowls (as they are upside down in the top rack).
We stack the washer as best we can, given that the bottom shelf is almost too short for most of our plates. We have previous dishwasher usage experience, so we know how to stack it.
The big question here is "Is this a crappy dishwasher, to be replaced? Or is it an okay dishwasher that's somehow not working at its best?"
Thanks!
The manual was not present when we bought the house. We have used other dishwashers before, so we have the general idea of how to stack one.
Dishes/glasses/etc are scraped if there is food on them, rinsed if the washer isn't going to be run immediately.
Often what's on the dishes post-wash isn't large pieces, but a "film" of the food that was there. Sometimes it is visible pieces, though.
The pools that form are on the bottoms of the upside-down cups and bowls in the top shelf. I'm not sure how a glass bottom will drain if it is standing at a 90 degree angle. Our top shelf doesn't easily allow the glasses to put set at an angle.
What I'm mostly wondering is whether we have a lousy washer that doesn't wash/rinse well, or whether we have a decent washer that needs repair.
Thanks!
Are you loading the dishwasher as described in the Owner Manual? Is food allowed to dry on the plates and utensils before the dishwasher is started? Are there large accumulations of food left on the dishes and silverware? Anytime water has pooled in items placed in a dishwasher, it's because the items were not properly placed in the dishwasher so that they may drain. Not all items can be placed in a dishwasher so that they can drain. You need to orient anything put in the dishwasher in it's best position so that it can drain.
