Thermador Dishwasher E34 and Continuous Filling: Verify the Code Before Blaming the Inlet Valve

Do not treat “intake valve stuck open” as a confirmed diagnosis. Thermador's US dishwasher error-code page lists E3400, not a standalone E34, and describes E3400 as an issue with water flowing into the dishwasher or filling system; it also lists E3100 as a base-water/leak-protection condition.
