Possible Causes
Corrupted firmware in main PCB, Power surge damage to microcontroller, Faulty EEPROM or flash memory, Incomplete factory reset
How to Fix / Troubleshooting
Safety first: Disconnect from mains before extended troubleshooting.
- Factory reset (if available): Consult the Tefal user manual for your specific model to perform a factory reset (often involves holding specific buttons while plugging in).
- Stable power: Plug the cooker directly into a wall outlet, not a power strip or extension, to avoid voltage drops.
- Retry basic program: After reset, try a simple program like reheat or keep warm. If E9 persists, internal memory is likely damaged.
- Service requirement: Firmware reprogramming or main PCB replacement is required. This is not user-serviceable; contact an authorized Tefal service center.
