GE Washer Error Code 66

Error code 66 on a GE washer indicates a Drive Motor Inverter Fault. The inverter board, which controls motor speed during wash and spin cycles, has detected and reported an internal fault condition. This will typically stop the washer mid-cycle or prevent it from starting a spin cycle. A Service Mode Spin Test is the recommended first diagnostic step to identify the root cause.

It is not recommended to continue using the washer while code 66 is active. A drive motor inverter fault can indicate an electrical issue that could worsen with continued use, potentially causing additional component damage. The washer may also fail to complete spin cycles, leaving laundry soaking wet. Discontinue use until the fault is diagnosed and resolved.

Resetting the washer by unplugging it for a few minutes may temporarily clear the code, but the fault will almost certainly return if the underlying cause has not been corrected. A reset does not repair a failing inverter board, a damaged motor, or a wiring problem. Running the Service Mode Spin Test after a reset can help determine whether the fault is consistent or intermittent.

Some causes of error code 66, such as a loose wiring connector between the inverter board and the motor, can be addressed by a knowledgeable DIYer comfortable working with appliance electronics. However, diagnosing this code accurately requires running Service Mode test 11, which involves specific control panel sequences. Replacing the inverter board or drive motor involves working near high-voltage components, so professional service is recommended if you are not experienced with appliance repair.

Repair costs depend on the root cause. If only wiring or connectors need attention, the cost may be limited to a service call fee, typically in the range of $75 to $150. A replacement inverter board generally costs between $100 and $250 for the part, with additional labor charges. A drive motor replacement can cost more, often in the $150 to $350 range for the part alone, plus labor.
