What E may mean on a La Cornue appliance, the symptoms you might see, safe checks you can perform, and when it is time to call a technician.
The E symbol on a La Cornue Château induction hob display is an error message for an electronic failure.
Model compatibility: La Cornue reuses codes across series and model years, so E 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 E on the induction hob display is an error message for an electronic failure.
When a La Cornue induction cooktop shows the letter E, the hob is reporting an electronic failure. In the display table of the guide, E is listed as an error message, next to the symbols for residual heat, booster and locking.
The entry covers the induction hob module of the current G4 series: Château 90, Château 120 and Château 150, as well as the induction ranges described in the same guide.
The guide describes E only as an electronic failure and gives the owner no fix for it. Turn the zone off with its control knob, leave the hob alone and do not open the appliance. Electrical faults are work for a technician.
For a La Cornue cooktop showing E in Los Angeles, call (310) 570-2050 and ask for cooktop repair. Have the code, the cooktop model and what you saw on the display ready when you call.
