How to Fix / Troubleshooting
Safety: Disconnect power before accessing internal components.
- Power reset: Turn off the breaker for 5 minutes to fully discharge the electronics, then restore power and test again.
- Check for recent repairs: If a board was recently replaced, verify that the correct Etna part number was installed and that any configuration jumpers or DIP switches are set according to the service manual.
- Service mode: Some Etna models require a calibration procedure after board replacement. Refer to the technical documentation for entering service mode and recalibrating zones.
- Board replacement: If E8 appears without any prior work and cannot be cleared, the control board’s memory (EEPROM) may be corrupted and the board should be replaced.
