Miele Dishwasher Error Codes: What They Mean and How to Respond

Miele dishwashers are engineered with sophisticated diagnostic systems that display error codes when problems occur. Understanding these codes helps you respond appropriately and communicate effectively with service technicians.

F11 indicates a drainage problem. Check for food debris in the filter, kinked drain hoses, or blocked garbage disposals. If clearing obvious obstructions does not resolve the code, the drain pump may require service.

F12 and F13 relate to water intake issues. Verify the water supply valve is open and the inlet hose is not kinked. Hard water areas may experience inlet valve problems from mineral buildup.

F14 signals a water heating problem. The dishwasher cannot reach the required temperature. This may indicate a failed heating element or sensor requiring professional diagnosis.

F24 and F25 relate to water level sensing. These errors can occur from faulty sensors or control board issues. Attempt a reset before calling for service.

F32 indicates a door closure problem. Check that nothing obstructs the door seal and that the latch mechanism operates smoothly. Worn door gaskets can trigger this error.

F51 through F53 involve circulation pump issues. The dishwasher cannot circulate water properly. These codes typically require professional diagnosis of pump and motor components.

F70 indicates a leak detection fault. The base flood switch has triggered. Check under the dishwasher for standing water and inspect hoses for leaks. This safety feature prevents water damage.

F78 relates to the circulation pump not running properly. This may be caused by a pump blockage, motor failure, or control board malfunction.

Always note the exact error code before attempting a reset. Multiple occurrences of the same code indicate an underlying problem that requires professional attention rather than repeated resetting.
