---------------------------------------------------- Hello All-
I am trying to figure out what is going on with my dishwasher -
just recently my top rack of dishes does not come out any better
than when I put it in.... *Any ideas or help would be greatly
appreciated! Thanks again = )

----------------------------------------------------

Make sure the upper spray arm is rotating and getting water. *Trace
the
plumbing that goes to it and look for loose connections. *Can you
tell if water is spraying or not?

Thank you for your response.

I disconnected the feed tube which goes up the back
of the dishwasher and everything was connected tightly although with
a
large amt. of mineral buildup....

I did try to open the dishwasher when it was running and it did not
seem that the
arm was rotating - (The arm will rotate though)...
But I do think the arm was getting some water because it was dripping
from
the edges of the arm.
Awaiting your best advice = )

I've really only "dug into" a couple of DW's in depth. Assuming spray
arms are similar (?), the arm had several holes in it for water to spray
out, The holes were at an angle which makes the arm rotate as it sprays
water. These holes over time can get clogged with crud. In your case,
evidence of mineral buildup in other areas makes me think possibly
mineral buildup in the spray arm holes is possible. Total or partial
blockage would cause it not to spin or spin weakly.

Clean out the holes maybe with a paper clip or something. Careful not to
alter/damage the holes when cleaning since they are only plastic. After
clearing holes take a garden hose and shoot water in the holes backwards
and forwards to clear further crud in the holes and arms.

If it is mineral deposits they will not clear easily like food particles
might. They will stick to stuff hard. Vinegar dissolves calcium buildup I
believe. There are also a product called CLR (dissolves calcium, lime and
iron rust).
