Low Medium High

Code Meaning Severity Common Symptom

E1 Cooktop overheating High One or more zones stop heating while set to boost or high power, particularly during prolonged cooking sessions. View E2 No compatible cookware Low Placing a pan on an induction zone and selecting power results in E2 appearing and no heat being generated — the pan stays cold. View E3 Coil sensor fault High One induction zone refuses to heat regardless of which pan is used — the zone display shows E3 immediately when that zone is selected. View E4 PCB communication fault High Touching any zone control or power level button produces no result — the cooktop is powered (display may be lit) but completely inoperative. View E5 Residual heat sensor fault Medium The residual heat warning symbol for one zone remains lit even after the cooktop has been completely cold for several hours, indicating a false-hot reading from the sensor. View E6 Supply voltage fault High When multiple zones are running at high power, all zones simultaneously cut out and E6 appears as the voltage sags below the acceptable minimum under the combined electrical load. View E7 Touch panel locked Low Touching zone power buttons or adjusting power levels has no effect — the cooktop appears powered but completely ignores all user inputs. View
