GE Washer Error Code 203

Error code 203 on a GE washer indicates a Compressor Motor Inverter Fault, meaning the compressor motor inverter board has detected and reported a fault condition. This board controls the compressor motor, and the fault can be caused by incorrect supply voltage, a failed inverter board, a wiring problem, or a failing compressor motor. Diagnosis starts with verifying that the AC voltage at connector CN8 falls between 102VAC and 132VAC.

You should not continue operating the washer while error code 203 is active. The inverter board fault means the compressor motor is not being properly controlled, and running the machine in this condition could worsen the underlying fault or cause additional component damage. Disconnect power and have the unit diagnosed before resuming use.

A power reset may temporarily clear the error code, but if the underlying fault condition still exists, the code will return once the machine attempts to operate again. Resetting without addressing the root cause, such as a voltage problem or a failed inverter board, will not fix the issue. A proper diagnosis of the inverter board supply voltage and components is necessary for a lasting repair.

Some aspects of diagnosing error 203 require working with live AC voltage at the inverter board connector CN8, which carries real shock hazard and should only be performed by someone comfortable with electrical safety practices. Checking for a tripped breaker or inspecting visible wiring for damage are safer tasks a homeowner can attempt. Replacing the inverter board is a more advanced repair that requires proper precautions and some electrical knowledge.

Repair costs depend on the root cause. If the fault is a wiring or connector issue, repair costs may be minimal, typically in the range of a service call fee. If the compressor motor inverter board requires replacement, parts and labor combined can range from roughly $150 to $400 or more depending on parts availability and local labor rates. A compressor motor replacement would be at the higher end of the repair cost spectrum.
