Possible Causes

Corrupted firmware on control PCB, Power surge damage, Incorrect replacement control board not programmed for model

How to Fix / Troubleshooting

Safety first: Disconnect from mains before any internal work. Firmware and configuration issues require specialist tools.

  • Power reset: Isolate the hob for 10 minutes, then restore power. Sometimes the control board will reinitialise.
  • Check for recent work: If the hob or control board was recently replaced, the new PCB may not be correctly configured for your Montpellier model.
  • Surge protection: If E9 appeared after a storm or power cut, consider having an electrician check your supply and fit surge protection.
  • Service intervention: A Montpellier-authorised technician may need to reprogram or replace the control PCB using manufacturer tools.
