E2 on a CornuFé induction range means the electronic unit is too hot, sometimes because a pan boiled dry.
Model compatibility: La Cornue reuses codes across series and model years, so E2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
The electronic unit is too hot; it can also appear if a pan boiled dry.
E2 on a La Cornue CornuFé induction range tells you the electronic unit is too hot. The manual adds that in extreme cases it can also show up when a cooking utensil has been left to boil dry.
The entry is for CornuFé induction ranges. The guide is filed as CornuFé 110 Induction, while its title text reads CornuFé 44 Induction Range.
The induction hob can diagnose some problems itself and show them on the control display. For E2 the manual asks you to look at how the cooker is installed and make sure there is enough ventilation around it. If you are unsure, it points you to your installer or a qualified repair engineer.
