Why E2 appears
An induction hob can run its own diagnosis and report certain problems on the control display. E2 is one of those reports: the electronic unit has become too hot. According to the guide, extreme cases include a cooking utensil that has boiled dry.
Ranges concerned
CornuFé induction ranges. The guide carries the file name CornuFé 110 Induction, yet its title text names the CornuFé 44 Induction Range.
What the guide asks you to check
How the cooker has been installed.
Whether enough ventilation reaches the cooker.
If doubt remains, speak to the installer or a qualified repair engineer.
