I also have a serial number if needed.
I see the parts # XXXXX and #17 on the diagram, but now where these parts are found in the dishwasher. The diagram does not indicate where.
Can I, a non-technetian (SP?), " pull out the "nit"? What is the unit, actually?
How about #5, where is that?
Will unclogging # XXXXX of food particles, correct the problem of reside crumbs being left in the glasses and cups? Or might that be a separate problem?
I believe that is beyond my comfort level - to ppull out the nit as you described.
However, I probably can check # XXXXX the valve. Again, where will I find it please?
Next time, I'll pjhone for a repair man to come,
but thanks for trying.
