Fisher & Paykel Dishwasher Error Code FC0

FC0 indicates a motor controller communications fault, meaning the wash controller and motor controller boards have lost their communication link. Without this link, the dishwasher cannot safely run the wash motor and will stop the cycle. The fault can be caused by a loose wiring connection, a corroded harness, or a failed controller board.

A reset may temporarily clear the FC0 code if the fault is intermittent, but it will return if the underlying cause is not addressed. Fisher & Paykel recommends running a rinse cycle on both tubs after the code appears to assess whether the machine can operate correctly. If the error reappears during or after the rinse cycle, a reset alone will not resolve the problem.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, you may pay only a service call fee, typically in the range of $80 to $150. If a motor controller or wash controller board needs replacement, parts and labor combined can range from $200 to $500 or more depending on your region and the specific model. Getting a diagnostic assessment before authorizing parts replacement is recommended to avoid unnecessary costs.

Some FC0 faults can be resolved without professional help if the cause is a loose or disconnected wiring connector, which does not require any parts. However, if the fault is caused by a failed motor controller or wash controller board, replacing those components can be complex and may require a qualified technician to safely access internal wiring and confirm the correct diagnosis before purchasing parts.

FC0 is not a water leak or electrical shock hazard, but the dishwasher will not complete normal wash cycles with this fault active. Continuing to attempt cycles without addressing the fault is unlikely to cause further damage, but the machine will not clean dishes effectively and may repeatedly stop mid-cycle. It is best to diagnose and resolve the fault before regular use.
