Miele Dishwasher F51 Error Code: Circulation Pump or Pressure Fault
Quick Answer
Miele F51 is a circulation or pressure fault. Like F78, start by checking the filter and impeller for blockage - a partially blocked impeller causes both F51 and F78 on different model generations. Also check that the wash cabinet water level is correct; low water from an intake issue (F14) can starve the circulation pump and trigger F51.

If the filter and water level are correct, the pump pressure sensor or the pump assembly itself requires diagnosis.

What Does the F51 Code Mean?
F51 on Miele G series dishwashers typically indicates a pressure or flow anomaly in the main circulation circuit. Depending on the model, it can represent a pressure switch fault, low water level condition affecting pump operation, or a pump performance issue distinct from the motor fault (F78). The distinction matters because F51 may be resolvable by addressing water supply or filter conditions, whereas F78 is more definitively a pump motor failure.
