Quick answer
Code 12 is a lid-lock switching-device failure or short in the lock circuit.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so Code 12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Seeing this code on your Fisher & Paykel appliance?
Book a specialist visit for a clear estimate and approval before any repair.
No. The old Fisher record identifies the condition described above, but it does not by itself prove which component has failed. Diagnosis should confirm the cause on the exact model.
Do not use repeated resets as a way to keep operating through **Code 12**. Follow the safe stop conditions above and arrange diagnosis when the condition returns or presents an active hazard.
Provide the full model number, the exact code or symptom, what the appliance was doing when it appeared, and whether the condition returned after any safe owner-level check.
