The dishes, glassware and sliverware do not look
There
are 3 standard answers to solving the white-deposits-on -dishes
problem: 1) Use a rinse aid; 2) use less detergent; 3) use vinegar in
the washer. If you have hard water, none of these may work, especially
if you've had the problem for a while. Because phosphates were ordered
removed from dishwasher detergents, hard water minerals can now react
with the soap to create a heavy greasy-feeling scum. That scum can
build up in the water lines, arms, bottom reservoir, and filter,
providing an endless supply of goo to spray on your dishes. This can be
fixed. You need to remove and clean out the spray arms, the filters,
and especially the array of parts at the bottom of the tub. I've seen
up to 1 cup of coagulated/crystallized scum in the bottom of dishwasher
tubs. Once you clean out the scum, then run the washer empty with a completely full detergent cup on
the highest temperature setting, extra rinse. Before you start it add
to the detergent cup 1 teaspoon of TSP(tri-sodium phosphate), a very
powerful phosphate cleaner available at hardware stores. Your washer
will now have all scum gone from the inner workings. From now on you
must always fill both your detergent and pre-wash cups to the max and
use a high temperature water setting, extra rinse. Chemically what
you're trying to do is add so much detergent that the scum-forming
reaction is overwhelmed by the dispersant action of the detergent, and
the extra heat helps this to be more effective. I am not a fan of
vinegar in the wash cycle. Why? In some washers the vinegar fumes can
reach the exposed contacts of the printed circuit board or touch pad,
corrode them, and then your washer won't work at all, along with being
very expensive to fix.
