Insignia Internal Communication or Configuration Error

Induction cooktop displays E6 and all burners may be disabled.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty main control board, Corrupted firmware, Loose inter-board harness, Power surge damage

Safety first: Disconnect power at the breaker before servicing.

Power reset: Turn the breaker OFF for 10 minutes, then back ON. If E6 clears, monitor for recurrence.
Inspect harnesses: Remove the cooktop and check all harnesses between the user interface board and power board. Reseat connectors firmly.
Board replacement: If E6 persists, replace the main power/control board assembly. On some Insignia models, the UI and power board are replaced together as a kit.
