Possible Causes
Corrupted firmware on main PCB, Loose display-to-main-board ribbon cable, Electrical noise or surge damage, Faulty main microcontroller
How to Fix / Troubleshooting
Safety first: Unplug the unit before opening.
- Power cycle: Disconnect from mains for 10 minutes to allow capacitors to discharge, then reconnect and test. This can clear transient MCU faults.
- Check internal connectors: Open the control panel and verify that the ribbon cable between the display board (if separate) and the main PCB is fully seated and not damaged.
- Inspect for moisture: Look for signs of condensation or liquid ingress around the control panel. Dry thoroughly and clean with isopropyl alcohol if needed.
- Firmware/PCB replacement: If E9 persists, the main PCB may require replacement. Morphy Richards typically supplies the control board as a complete assembly rather than offering firmware reflash tools to consumers.
