Fisher & Paykel Dishwasher Error Code FF

The FF code means the top tub is not responding to the dishwasher's control system. This error is specific to Fisher & Paykel double-drawer models and points to a communication failure involving the top drawer's controller. The fault can be caused by a defective controller board, a loose wiring connector, or a damaged harness.

A reset may temporarily clear the FF code, but it will return if the underlying fault is still present. Because this code indicates a hardware communication failure rather than a software glitch, the root cause must be identified and repaired to resolve the fault permanently. Use the reset only as a first step to confirm whether the code is persistent.

Repair costs vary depending on the root cause. If only a connector needs reseating or a harness needs repair, costs may be limited to a service call fee, typically in the range of $80 to $150. If the top tub controller board requires replacement, parts and labor combined can range from $200 to $450 or more depending on parts availability and local labor rates.

Some causes of the FF code, such as a loose wiring connector, can be addressed without specialized tools if you are comfortable working inside the appliance. However, the key diagnostic step involves swapping the top and bottom controllers to determine whether the board itself has failed, which requires some technical familiarity. If the controller board is confirmed faulty, replacing it typically requires sourcing the correct part and basic appliance repair skills.

The top drawer will not operate normally while the FF fault is active, so continued use of that drawer is not possible in its faulted state. The bottom drawer may still function independently. It is advisable to have the fault diagnosed promptly to avoid any secondary issues from an unresponsive control board.
