Fisher & Paykel Dishwasher Error Code FC1

FC1 indicates a communication failure between the wash controller and the motor controller inside the dishwasher. These two boards need to continuously exchange data for the appliance to run correctly. When that communication breaks down, the dishwasher logs FC1 and stops the cycle. The fault can be caused by loose wiring, a damaged harness, or a failed control board.

A reset may temporarily clear the FC1 code if the fault was caused by a brief power fluctuation or a momentary communication dropout. However, if the underlying cause is a damaged wiring harness or a failed control board, the code will return as soon as the dishwasher attempts to run again. Fisher & Paykel recommends running a rinse cycle on both tubs after a reset to confirm whether the fault is truly resolved.

Repair costs vary depending on the root cause. If only a connector needs reseating or a harness needs replacing, costs are generally in the range of $50 to $150 for parts and labor. If a control board needs to be replaced, total repair costs including labor typically fall in the range of $200 to $450 depending on which board has failed and local labor rates. Getting a diagnostic assessment from a technician before committing to parts is advisable.

Some FC1 faults are caused by loose wiring connectors, which a confident DIYer can address by locating and reseating the connector between the wash controller and motor controller. However, if the fault persists after checking the wiring, the repair likely involves replacing a control board, which requires disassembly and comfort working around electrical components. If you are not experienced with appliance repair, a qualified technician is the safer choice.

The dishwasher is designed to stop operation when FC1 is detected, so continuing to force cycles is not recommended. Running the appliance with an unresolved controller communication fault could result in the motor operating outside expected parameters. It is best to diagnose and resolve the fault before resuming regular use.
