Electrolux Range Error Code Bake + Clean (LEDs 1,5)

The Bake + Clean error code (LEDs 1 and 5 illuminated simultaneously) on an Electrolux range indicates that the electronic control board has detected an incorrect EEPROM checksum. The EEPROM (Electrically Erasable Programmable Read-Only Memory) is a small non-volatile memory chip integrated into the control board that stores critical configuration data, calibration values, and operational parameters for the range. A checksum is a calculated value the control uses to verify that stored data is intact and uncorrupted. When the checksum the board calculates does not match the expected value, this fault code is triggered.

This type of error typically points to data corruption within the EEPROM itself. Corruption can result from a power surge or voltage spike that wrote invalid data to the memory, a partial power loss during a write cycle, or gradual degradation of the EEPROM chip over time. In some cases, a momentary power interruption during a self-clean cycle can trigger the fault, since control boards perform write operations during and after high-heat events.

Because the EEPROM is physically integrated into the electronic control board assembly, it is not a component that can be serviced or reprogrammed independently in the field. The corrective action is replacement of the entire electronic control board. Attempting to operate the range with a corrupted EEPROM checksum can result in unpredictable control behavior, so the unit should not be used until the board has been replaced.
