Bosch Dishwasher E15 Error — Water Inlet Valve Replacement
Problem: The dishwasher displayed an E15 error, ran the drain pump continuously, and was leaking water beneath the unit. It would not begin a normal wash cycle.
Diagnosis: Water had collected in the base pan, activating the internal float switch and triggering flood protection mode. The source was traced to a failed water inlet valve leaking internally into the base pan.
Repair: Replaced the failed OEM water inlet valve (Part #10023852). Removed all standing water from the leak tray, reassembled, and performed a complete operational and leak test. E15 error cleared, drain pump no longer running continuously, no leaks detected. Technicians: Shane and Cody.
