Dishes after cycling come out with very small particles on them, not clean

[FONT=Times New Roman][SIZE=3][COLOR=#000000]No matter what cycle I set the dishwasher on the dishes come out with very small particles of food on them. It my understanding that the dish washer has a food grinder in it to take care of this, but yet coffee ground size particles are all over the dishes. Can you advise? what parts do I need to order if any, or kits?[/COLOR][/SIZE][/FONT]

Dan,

What has changed since this started ?

Changed detergent ?

Changed rinse aid ?

Changed water temperature(lowerred)?

Any of these changes can effect the washability of the dishwasher.

If nothing has changed,

Check for debris in the bottom of the tub and filters

Check the dishwasher for a proper fill level.
(should be touching the bottom of the heat element).

Check for a proper drain(tub empty in 40 to 60 minutes).

If all that is proper, you may have to dismantle the pump and replace the impeller kit.

Are you sure it is food particles or is it just grit, if grit see the following link (at bottom of the page)
