Replaced the Detergent and Rinse Aid Dispenser as recommended in several questions and answers. Viewed the instructional video provided by Appliance Parts Pros. Unfortunately, my model Bosch is a higher end unit than is portrayed in the video, so there was quite a bit of head scratching involved. But the basic procedure turned out to be the same -- just a lot of different details. It all worked in the end, but was a lot more difficult than I was expecting.
