Possible Causes
Corrupted firmware, Power surge damage to control board, Shorted component on PCB, Loose internal connectors
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker before inspecting any internal components.
- Hard reset: Disconnect the machine from mains power for at least 15 minutes. Plug it back in directly to a wall outlet (avoid extension leads) and try to power on.
- Check for moisture: Inspect around the control panel and top cover for signs of water ingress (spills, condensation). Allow the unit to dry in a warm, dry room for 24 hours before retrying.
- Inspect power cord and plug: Ensure the Kenwood power cord is not damaged and the plug fits firmly in the socket.
- Do not attempt board-level repair: The main PCB contains high-voltage components. Do not open or attempt to repair it unless you are a qualified electronics technician.
- Service recommended: If E09 remains, the main control board likely needs replacement and should be done by an authorized service center.
