A Bosch dishwasher was experiencing an issue where the drain pump ran continuously, displaying an error code. The error indicated a leak, so I began by examining the dishwasher's internal components. I identified the leak source as the diverter valve assembly. This assembly directs water flow, and a leak here can trigger the error. I carefully disassembled the assembly, inspecting each part for damage or wear. After confirming the leak, I replaced the faulty diverter valve assembly with a new one. Post-replacement, I tested the dishwasher to ensure the error was resolved and the drain pump functioned correctly. The dishwasher now operates without issues, and the error code has been cleared.
