I have a Kitchenaid KUDS25SHBL1 dishwasher that is doing a great job of cleaning the bottom rack of dishes, but even after replacing the very top sprayer and the complete rotating assembly sprayer for center unit, dishes are oily, muddy and over all not comming clean.
Help Please

Replaced:
All seals, checkvalve (To make sure drained water does not come back in)
Center rotating assembly
Top sprayer assembly
Replaced seals gaskets, for bottom assembly

Using, Cascade W/Grease Fighting Power of DAWN. Still not coming clean.
Help Please.

I looked up some info on your detergent looks like it gets a pretty poor rating at least on the following site.
Cascade - Cascade® with the Grease Fighting Power of Dawn® Gel customer reviews - product reviews - read top consumer ratings

Perhaps try another detergent. I would go with the powder type.
Gel packs also do not get great ratings.

A common problem is the unit not filling with enough water.
Most units fill to just under the heating element.
This can be checked by adding a couple quarts of hot water after each fill during a cycle. Just be careful to not overfill it.
If it now washes OK then check the fill valve.

Often if the fill is low you will also hear a growling sound because the pump will cavitate (suck in air).
The most common cause is a dirty screen filter on the input side of the fill valve. Remove the valve from the unit and clean/check the filter.
Do not permanently remove it from the valve as it is there to keep crud out of the valve which could hold it open and cause a flood.

If it still does not fill correctly I would replace the fill valve.

PS: Be sure to shut off the power and the water supply to the unit. Have paper towels etc. handy to wipe up any spilled water. Get a small pan/bowl etc. that will fit under the valve then loosen the input water line let it drip into the container emptying it as necessary. This will minimize the amount of water spilled.
