I followed the excellent parts diagram on the PartSelect.com site to remove one screw after another, until I arrived at the disintegrated impeller.

After replacing it, I reversed the procedure, again refering to the diagram frequently.

In the process, I discovered that one part, the pump housing filter, had shrunk over the years, preventing the pump cover to seat properly. Although I had a few service calls in the past (we had a service contract until a month ago), no one could find the reason why the cover did not tighten down. I was told the screw holes were stripped, and it would not be worth replacing the whole base.

Anyway, I used a Dremel grinder on the filter latches to increase the diameter of the filter, and it fits now.

The nine-year old dishwasher runs like a charm again.

Incidentally, the ordered parts arrived within 24 hours! How do they accomplish such fast delivery?
