Fisher & Paykel Washer Error Code Unfamiliar light pattern with single beep every second

This alert means the washer's control system has detected an internal fault that it cannot categorize into one of its standard, named error codes. The machine knows something is wrong but cannot identify the specific cause for the user. The beep every second paired with an unusual LED pattern is the control board's fallback alert state. It requires a power reset as the first diagnostic step, followed by further investigation if the fault returns.

It is not recommended to continue running the washer while this fault is active. Because the machine cannot identify the specific problem, there is no way to know whether the fault involves a component critical to safe operation, such as the motor controller or a water-related system. Stop using the appliance, perform the power reset, and confirm normal operation before running a full load.

If the fault returns repeatedly after a power reset, the cause is likely a hardware component rather than a temporary software glitch. At that point, a qualified technician should inspect the wiring harness connections, check for moisture near the control board, and test the main control board and any secondary modules for proper function. Continuing to reset without addressing the root cause will not produce a lasting fix.

A power reset is the recommended first step and does resolve this fault in many cases, particularly when a transient voltage event or temporary software glitch is the cause. Unplug the machine from the wall outlet, wait a full 60 seconds to allow the control board to fully discharge and reinitialize, then plug it back in and run a cycle. If the fault returns after the reset, the underlying cause is a hardware or persistent software issue that requires further diagnosis.

The repair cost depends entirely on what is causing the fault. If a power reset resolves the issue, there is no parts cost at all. If the main control board requires replacement, parts and labor typically range from $200 to $450 depending on the specific model and local labor rates. Wiring or connector repairs are generally less expensive, often falling in the $75 to $200 range including a service call.
