FFF code - Control error, failed EEPROM
The main control operates a series of software commands, which control the various features and functions of the oven. Each function or operation has a numerical value assigned to it. The numerical values can be added up - this is called the check sum operation. Every time the system is powered up and after each clean cycle the system performs a check sum and compares the value to the value programmed into the software (stored in memory).
An EEPROM check sum error or FFF code occurs when the values differ. If this happens, replace the oven control board (also called clock or ERC).
Replace the oven control board (also called clock or ERC).
Hope this helps.
