How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow it to sit for several minutes before attempting any reset.
- Basic reset: Unplug the cooker for at least 10 minutes to allow capacitors to discharge, then plug back in and try again.
- Check for moisture: Inspect around the control panel for signs of condensation or liquid spills. If the unit was exposed to moisture, allow it to dry in a warm, dry place for 24 hours (unplugged).
- Avoid disassembly if under warranty: Internal board access may void warranty. If E9 persists after a reset and drying period, contact Breville support or a qualified technician.
