Fisher & Paykel Washer Error Code Lid Lock flashing

The Lid Lock flashing indicator on a Fisher & Paykel washer signals that the control system cannot confirm the lid is properly closed and locked before or during a wash cycle. The lid lock is a safety mechanism required for the washer to operate. When the control board sends power to the lid lock assembly and does not receive the expected confirmation signal back, the lid lock light begins flashing and the cycle will not proceed. This protects users from exposure to a spinning drum and prevents water from running with an open lid.

The lid lock assembly contains a locking solenoid or actuator and a position switch that communicates lid status to the control board. If the lid is physically open, the switch simply will not close and the confirmation signal is absent. If the lid appears closed but the error persists, the problem is usually internal to the lock mechanism itself. Common failure points include a worn or broken latch strike that prevents the lock from engaging fully, a failed solenoid or actuator that cannot extend the locking pin, or a faulty position switch that fails to send the closed signal even when the lid is properly shut.

Wiring between the lid lock assembly and the control board can also cause this symptom. A loose connector at the lock assembly or a damaged harness can interrupt the signal path, producing the same flashing indicator as a failed lock component. In less common cases, the control board itself may be unable to properly interpret or send signals to the lid lock circuit, though the lock assembly is the statistically more likely failure point and should be diagnosed first.
