What the F79 Fault Code Means
The F79 fault code indicates a fault with the interaction or communication between the circulation pump and the control system. Unlike F78, which can sometimes be resolved by freeing a dry pump, F79 points to a more technical fault within the pump control circuit. Miele confirms this cannot be remedied by the user and requires professional attention.
Common Reasons This Fault Appears
