GE Washer Error Code E43

The E43 error code on a GE washer indicates a DC fault within the inverter control board, classified as a non-recoverable inverter failure. The inverter board is responsible for converting DC power into the variable-frequency AC power used to drive the brushless DC motor that spins the wash drum. When the inverter detects an internal DC fault it cannot correct through normal recovery routines, it locks out and throws the E43 code to prevent further damage to the motor or electrical system.

A non-recoverable fault means the inverter's internal diagnostics have determined that the failure is not a transient event such as a brief voltage spike or temporary overload. Instead, the fault represents a hard failure within the inverter circuitry itself. This can involve failed switching transistors (IGBTs), shorted internal capacitors, failed gate driver circuits, or a corrupted control signal path. Because the inverter cannot self-correct, the washer will not attempt to restart the motor until the board is replaced.

The primary and essentially only corrective action for E43 is replacement of the inverter control board. There are no adjustments or reset sequences that resolve a non-recoverable DC fault of this type. If the board has failed due to a recurring power quality issue, such as voltage surges or unstable supply voltage, that underlying cause should be addressed before installing the replacement board to prevent repeat failures.
