Quick answer

E01 typically points to a sensor or control communication fault in the refrigerator.

Model compatibility: La Cornue reuses codes across series and model years, so E01 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means
