Miele Dishwasher Error Code F68

F68 means the frequency converter is detecting a speed signal from the electronic control board when the circulation pump should be stopped. The control board is sending an unintended run command to the pump during a shutoff state. This is a control circuit fault, and Miele's diagnostic procedure points to the electronic control board as the component to replace.

It is not recommended to continue running the dishwasher while F68 is active. The error indicates the circulation pump may be operating outside of its intended cycle, which can cause unnecessary wear on the pump motor and potentially lead to other component failures. The machine should be left off until the fault is diagnosed and repaired.

A basic reset is unlikely to permanently clear F68 because the fault is caused by an internal failure in the electronic control board rather than a temporary software glitch. The error may clear briefly after a reset, but it will typically return once the dishwasher attempts to run a cycle. A lasting repair requires addressing the underlying hardware fault in the control board or associated wiring.

Resolving F68 typically requires replacing the electronic control board, which involves accessing internal components and disconnecting wiring harnesses. Technicians with experience in appliance electronics can perform this repair, but it is not a straightforward DIY task for most homeowners. Before replacing the board, it is worth inspecting all wiring connectors between the board and the frequency converter for visible damage.

Repair costs for F68 vary depending on whether the fix requires only wiring inspection or a full electronic control board replacement. A control board for a Miele dishwasher typically ranges from $150 to $400 or more for the part alone, with labor costs adding $100 to $250 depending on the service provider. Total repair costs can range from $250 to $650 or higher.
