GE Washer Error Code 33

Error code 33 on a GE washer indicates an inverter fault, meaning the inverter board has detected and reported an internal error to the main control board. The inverter board controls motor speed by managing power delivery, and when it faults, the washer stops the cycle automatically. This code shares its fault category with several related codes including 34, 41 through 51, 66 through 69, 71 through 75, and 92. Diagnosing the exact cause requires running the Service Mode spin test 14.

It is not advisable to continue running the washer once error code 33 has appeared. The inverter fault indicates the motor drive system is not operating correctly, and forcing additional cycles could cause further damage to the inverter board or the wash motor. The washer will typically stop the cycle on its own as a protective measure. Have the fault diagnosed before resuming regular use.

Resetting the washer by unplugging it for a few minutes may temporarily clear the error code display, but it will not resolve the underlying fault. If the inverter board, motor, or wiring has a real defect, the error code will return when the washer attempts to run again. A proper diagnosis using the Service Mode spin test 14 is needed to identify and correct the root cause before the code will clear permanently.

Some causes of error code 33 are DIY-friendly, such as checking and reseating wiring connectors between the inverter board and the main control board, or verifying that the washer is on a properly rated electrical circuit. However, testing motor windings and diagnosing inverter board failures requires a multimeter and familiarity with Service Mode diagnostics. Replacing the inverter board is a moderately involved repair that confident DIYers can attempt, but if you are unsure about working with appliance electronics, a qualified technician is recommended.

Repair costs depend on the root cause. If the fix involves reseating a wiring connector, there may be no parts cost, though a service call fee will still apply. Replacing the inverter board is typically the most expensive scenario, with parts and labor costs often ranging from $150 to $350 or more depending on the specific model and local labor rates. Getting a diagnostic assessment before committing to parts replacement is the best way to control costs.
