Possible Causes

Corrupted firmware on control board, Faulty communication between UI and power board, Power surge damage, Loose harness connectors

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker for at least 10 minutes.

  • Power reset: Restore power and check if E5 clears. If it does, monitor for recurrence.
  • Inspect harness: With power off, open the cooktop and inspect the harness between the user interface board and the power board. Reseat all connectors.
  • Check for damage: Look for burn marks or swollen components on the boards.
  • Board replacement: If E5 persists, replace the user interface board first if it is separate. If that does not resolve the issue, replace the power control board.

Firmware reprogramming, if supported, should be done only by authorized service centers.
