If you installed this yourself, why not remove the hose connection (under
the sink) run a cycle making certain the drain is connected to a lower
drain source, (outside), (basement) etc.
This should allow all foreign material in the drain lines to exit...just a
thought

Last January, we bought a new Kitchen Aid dishwasher, which cost about
$550. There were bargain brands for $300 but we decided to get a
better one this time. I installed it myself, as I have all the
dishwashers we've bought over the last 15 years.

It worked perfectly all year. We went on a ski vacation during the
week before Christmas and were gone for five days, during which time
the dishwasher was not used. When we got back, it started leaving
specks of dirt or food or whatever on some of the dishes. This
condition seems to be getting worse. I can't see why a week of
inactivity would cause this but this is the only time we were away for
an extended period of time and the problem started when we returned.

The user's manual suggests scraping the dishes before putting them
into the dishwasher and loading properly when this happens. We do both
and are doing nothing different than we were doing all year.

Before calling a repairman, I suggested that my wife run a cycle with
no dishes in in to clear out the lines, then to run a small load to
see what happens. She's doing that today. Any other suggestions as to
what might be causing this?
