Pulled out the dishwasher. Toweled up water in the drain pan to clear the code. Ran the dishwasher to observe where the leak was. It was dripping from the diverter valve assembly. Ordered a new assembly and searched YouTube for videos on taking apart a Bosch dishwasher. Replaced the part. $45 fix for a 6-year-old dishwasher. I could not get a service tech to even look at it for 60 days! Thanks AppliancePartsPros.com.
