Frigidaire Dishwasher Error Code PF

PF stands for Power Failure on a Frigidaire dishwasher. The code is triggered when the main control board's microprocessor detects that power to the unit was lost or interrupted. It also appears during first-time installation when the dishwasher is connected to power for the first time. In most cases, it is not a sign of a broken component.

The PF code itself is a notification about a past power interruption and does not indicate an active hazard. However, you should clear the code before starting a new cycle to ensure the control board is operating correctly. If the code keeps reappearing without any obvious power interruption, stop using the dishwasher until the wiring and control board have been inspected, as a short circuit in the control system could present a risk.

If PF reappears repeatedly, it usually points to one of two causes: recurring power supply issues such as a loose household circuit connection or a frequently tripping breaker, or an internal problem like a short circuit or damaged wiring in the control system. A faulty main control board can also cause the microprocessor to falsely log power failures. Start by checking your home's breaker and outlet, then inspect the control board wiring for damage before considering a board replacement.

Yes, pressing the START/CANCEL pad is the first step to clearing the PF code, and it resolves the issue in most situations. If the code remains after pressing START/CANCEL, opening and then firmly closing the door allows the door switch sensing circuit to reset, which often clears the code. If PF still persists after both steps, further diagnosis of the wiring and control board is needed.

If the PF code is caused by a power outage or first-time installation, there is no repair cost since a simple button press clears it. If the door switch needs adjustment or the wiring harness needs repair, costs are typically low, ranging from around $20 to $75 depending on parts and labor. Replacing the main control board, which is the last resort, generally costs between $150 and $350 including parts and professional labor.
