Miele dishwashers communicate problems through error codes and indicator lights. Understanding these messages helps you respond appropriately, potentially resolving minor issues without a service call.
F11 or F12 indicates water drainage problems. Check for kinks in the drain hose and clear the drain filter of debris. In Arizona, hard water deposits can clog drain components. Running a cleaning cycle may resolve minor blockages.
F13 or F14 relates to water intake issues. Verify the water supply is turned on and the inlet hose is not kinked. Check the inlet filter screen for mineral buildup. If the problem persists, the inlet valve may need professional attention.
F24 points to heating element or temperature sensor problems. The dishwasher cannot verify water is reaching proper temperature. This typically requires professional repair as it involves electrical components.
F70 or F78 suggests water leak detection. Miele dishwashers have sensors that detect water in the base pan. Check underneath for visible leaks. If water is present, identify the source before running the dishwasher again.
Intake/Drain light flashing indicates the dishwasher cannot fill or drain properly. This often relates to installation issues like improper drain hose height or a blocked air gap.
Technical fault warnings with solid lights usually indicate electronic control issues requiring professional diagnosis.
Before calling for service, try resetting your Miele by turning off the circuit breaker for 60 seconds. This clears temporary electronic glitches that sometimes trigger false error codes.
Document error codes before they clear. Write down the exact code or light pattern. This information helps technicians diagnose efficiently, potentially reducing repair time.
