John S Hamburg , NY October 19, 2020 Bosch dishwasher e15 error code. Got an E15 error code on my Bosch dishwasher. Pulled it out and noticed the water inlet valve was dripping. Ordered from AppliancePartsPros.com and got a new one the next day. Super easy fix and back up and running. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
