Possible Causes
Corrupted EEPROM on the control board, failed main PCB, power surge damage to the memory circuit, incorrect firmware configuration.
How to Fix / Troubleshooting
Safety: Unplug the microwave before any further action.
- Power reset: Leave unplugged for 15 minutes, then reconnect. Sometimes, transient memory errors clear after a full power-down.
- Check power quality: Avoid using the microwave on circuits with frequent surges; consider a surge protector rated for microwaves.
- If E15 persists: The main control board will likely need replacement or reprogramming with Princess-specific firmware, which must be performed by an authorized service center.
