Low Medium High

Code Meaning Severity Common Symptom

3 Control Area Obstructed Low A steady audible tone plays through the cooktop's speaker whenever any burner is turned on, and the tone stops only when the control area is cleared. View 20 General Cooktop Fault Medium Activating a cooking zone produces no heat even with compatible cookware in place, and the indicator for that zone may show the error. View 47 LIN Comm Error Medium The cooktop was running normally, then burners that were on no longer respond to power-level changes or shut off requests. View E4 Config Implausible Medium The cooktop completes its boot sequence but lands on a fault display instead of a ready-to-cook state. View E6 Electrical Supply Error Medium A pan sitting on a cooking zone with power called up produces no heat — the induction field cannot couple with the cookware's base. View E7 Zone Fault E7 Medium The zone indicator shows the error and no induction field is generated, even with compatible cookware in place. View E8 Internal Fan Error High Heating stops and zones deactivate because the fault-protection circuit has shut the cooktop down to prevent electronics overheating. View E9 Service Required High Every attempt to turn on a zone results in no action and E9 appears on the display, regardless of which zone is selected or what cookware is present. View E22 Stuck Touch Key Low User inputs are ignored because the cooktop is already reading a phantom press from the stuck key and will not accept a second simultaneous input. View EA Controller Error High Every cooking zone is disabled and EA appears on the display — the controller has decided that no safe cooking is possible until the error is cleared. View
