What the A-55 error code actually means
Your Continental washer's motor controller has lost or corrupted the settings it needs to run the motor properly. This is often caused by a power surge or interruption that scrambled the drive's internal configuration. A technician can usually fix this by reloading the correct settings from the washer's main computer board.

Questions people ask about A-55
What does A-55 mean on a Continental washer?
The A-55 code indicates a parameter error in the washer's inverter drive, which is the component that controls motor speed and operation. The inverter has lost or corrupted the configuration values it needs to run the motor. This fault is typically triggered by a power surge, power interruption, or a missing parameter download after a control board service. Correcting the machine ground and re-downloading parameters from the microprocessor are the first required steps.
Is it safe to keep using my washer when the A-55 code is displayed?
No, you should not continue operating the washer while the A-55 error is active. The inverter does not have valid parameters, which means the motor may not operate correctly or at all. Running the machine in this state risks further damage to the drive or motor. Stop using the washer and have the fault addressed before resuming normal operation.
How much will it cost to repair an A-55 error on a Continental washer?
If the fix involves only re-grounding the machine and reloading inverter parameters, repair costs are typically limited to a service call fee, which can range from $75 to $150 depending on your area. If the inverter drive itself has failed and requires replacement, total repair costs including parts and labor can range from $250 to $600 or more depending on parts pricing and local labor rates.
Can I fix the A-55 error myself, or do I need a technician?
The repair process involves verifying the chassis ground connection and re-downloading inverter parameters from the machine's microprocessor, which typically requires a technician with access to the correct service tools and procedures. A homeowner can check that the washer's power cord and plug are in good condition and that the outlet is properly grounded, but the parameter reload process is a technical procedure not suited to DIY repair.
Will resetting the washer clear the A-55 error code?
A simple power reset is unlikely to permanently clear the A-55 error if the underlying cause is corrupted or missing inverter parameters. The fault may temporarily disappear but will return because the root issue is not resolved. Clearing the code requires correcting the machine ground and performing a proper parameter download from the microprocessor to the inverter drive.
