GE Washer Error Code 43

Error code 43 on a GE washer indicates a Drive Motor Inverter Fault, meaning the inverter board that controls the drive motor has detected and reported a fault condition. This board manages motor speed throughout wash and spin cycles, and a failure here will typically stop the machine from operating normally. Diagnosis requires running Service Mode test 11, the Spin Test, to full completion to pinpoint the source of the fault.

It is not recommended to continue using the washer while code 43 is active. The inverter board fault indicates a problem in the motor control circuit, and running the machine in this condition could worsen an existing failure or cause additional damage to the motor or control electronics. The washer should remain out of service until the fault is properly diagnosed and resolved.

Resetting the washer by unplugging it for a few minutes may temporarily clear the code if the fault was caused by a one-time power event or overheating, and the machine may resume normal operation briefly. However, if the underlying component, such as the inverter board or drive motor, is actually failing, the code will return during the next cycle. A full Service Mode Spin Test is the correct way to determine whether the fault is persistent or was an isolated event.

Some instances of code 43 are caused by loose wiring connections or a temporary power event, which a knowledgeable DIYer can address by inspecting and reseating the wiring harness connectors between the motor and inverter board. However, if the fault points to a defective inverter board or drive motor, those repairs involve high-voltage components and should be handled by a qualified technician. Running Service Mode test 11 first is the correct starting point to narrow down the cause before any parts are replaced.

Repair costs vary depending on the root cause. If only wiring or connectors need attention, costs may be minimal, primarily covering a service call fee in the range of $75 to $150. Replacing the drive motor inverter board typically runs between $150 and $350 in parts and labor, while a drive motor replacement can push total repair costs into the $200 to $450 range depending on the specific model and local labor rates.
