LG Washer Error Code EEPROM

The EEPROM error means the memory chip on your washer's main control board (called the main PWB) has failed or become corrupted. This chip stores important operating data the washer needs to function. The error is detected and displayed specifically when you press START/PAUSE for the first time during Load Test Mode. The fix is to replace the main PWB assembly.

The EEPROM error appears during Load Test Mode diagnostics, not necessarily during a standard wash cycle, but it indicates the control board cannot reliably store or retrieve operational data. Continuing to use the washer with a failed EEPROM risks incorrect operation or unexpected behavior. It is best to address the issue before running additional cycles.

The cost depends on whether you hire a technician or replace the board yourself. Main PWB assemblies for LG washers typically range from around $100 to $300 or more depending on the model. Adding professional labor costs for diagnosis and installation, the total repair can range from roughly $150 to $450 or higher. Getting a quote before committing to the repair is advisable, especially on older machines.

The EEPROM chip is integrated directly into the main PWB and cannot be replaced as a standalone component in the field. Fixing this error requires replacing the entire main PWB assembly. A technician with experience in control board replacement can perform this repair, but it does involve disconnecting wiring harnesses and handling sensitive electronic components.

A power reset will not clear the EEPROM error because the fault is a hardware failure of the memory chip itself, not a temporary software glitch. The error will return when Load Test Mode is initiated again. The only resolution is replacing the main PWB assembly.
