April H Carson City , NV January 22, 2017 E 15 error code The inlet valve ended up being cracked, flooding the base pan and activated the E15 error code. Ordered the part from appliancepartspros.com and had the replacement within a day and a half. Great service, quick shipping, and accurate parts. Do note that the appliancepartspros website will have different part numbers than the bosch website part number. 20 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
