After doing a few minutes of research online, I suspected that the Bosch dishwasher was running a very extended period, due to it not sensing that the water was reaching a minimum temperature. The likely cause was a bad control board. After ordering this replacement part, I watch a tutorial video, on the installation. Repair took about 30 minutes, and the dishwasher is working like it should. Further inspection of the old control board showed that the relay controlling the heating element, had failed.
