Cause : EEPROM fault comes when data changes are not saved when the mains voltage is switched off. An EEPROM (Electrically Erasable Programmable Read-Only Memory) fault indicates an issue with the memory component of a device, typically in an electronic control system.

• The EEPROM stores crucial information such as configuration settings, calibration data, or firmware updates. If there's a fault with the EEPROM, it can lead to various issues with the device's functionality.
