I went on YouTube and found AppliancePartsPros.com video on how to replace the bottom seal on a Bosch dishwasher. Found the model number and ordered a new seal. When it arrived I replayed the YouTube video and followed the steps and replaced the seal. My model was not the same one in the video so I had to add a few extra steps and eventually got to the point of replacing the seal and then reassembling everything. No parts were left over so I turned on the power and water and ran a load of dishes. No leaks and clean dishes. Complete success.
