A Miele Dishwasher fault codes list includes:

Code F11 - This error code indicates a problem with water drainage. It could be due to a clogged filter combination in the cabinet, an obstruction in the drain pump caused by objects, deposits in the drain hose or drainage system, or a kinked drain hose. Clearing any blockages and ensuring proper hose alignment may resolve this issue.

Code F12/F13 - These fault codes signify a water intake error. Check if the stopcock, which controls the water supply, is closed. A clogged water inlet filter or a kinked inlet hose can also cause this error. Additionally, if the water pressure is lower than 0.3 bar, it’s recommended to consult an experienced engineer for further assistance.

Code F14 - The F14 error code indicates a problem with the heater pressure switch. This switch is responsible for measuring and regulating the water level inside the dishwasher during the heating process. If it malfunctions, the dishwasher may overfill. Seek professional help to diagnose and fix this issue.

Code F24 - This error code points to an issue with the heater relay contacts. The relay controls the heating system within the dishwasher. If the contacts are faulty, the water won’t heat properly. Repairing or replacing the relay may be necessary.

Code F32 - When the door lock fails to close properly, the F32 error code appears. This fault may occur if the door is manually closed too quickly. For dishwashers with automatic door closing features, it’s important to ensure that the mechanism is functioning correctly.

Code F70 - The F70 code indicates a problem with the float switch, which detects the water level inside the dishwasher. If the float switch is defective, it can trigger the activation of the waterproof system, preventing the dishwasher from operating normally. A trained technician can assess and resolve this issue.

Code F78 - This error code relates to a fault in the circulation pump. Potential causes include a disconnection between the electronic components and the circulation pump, a faulty frequency converter electronic device, or abnormal voltage levels affecting the pump’s operation. Expert assistance is recommended to address this fault.
