Thomas W Los Angeles , CA June 29, 2023 Bosch dishwasher leaking water intake valve (error code 15). First, I learned from an online Youtube video what Error Code 15 meant and proceeded with locating the water leak within my dishwasher. Next, I watched the repair video by AppliancePartsPros.com and ordered the replacement part. I followed the instructional video but I did not have to disconnect the drain hose from the air gap. I fully installed the dishwasher before running a test cycle to confirm that the appliance was fully operational again. If I were to carry out this repair again I would run the test cycle before reinstallling the appliance in case of any leaks due to improper installation.
