Continental Washer Error Code A-00

The A-00 code means the main microprocessor control board and the inverter drive unit have lost communication with each other. When this happens, the inverter will also show its own code, Er8. The microprocessor is required to supply 5 VDC through a communication cable at connector X-14 for the two components to exchange data. If that signal is missing or interrupted, the washer will stop operating and display A-00.

No, the washer will not operate normally with an active A-00 fault because the inverter cannot control the motor without communication from the microprocessor. Attempting to force cycles while this fault is present is not recommended, as the underlying electrical fault could potentially worsen. The machine should remain out of service until the communication issue is diagnosed and repaired.

A power reset may temporarily clear the displayed code, but the A-00 error will return as soon as the washer attempts to operate if the underlying communication fault has not been corrected. Because this code reflects an actual hardware or wiring problem between the microprocessor and the inverter, a reset alone is not a fix. The root cause must be identified and addressed for the fault to be permanently resolved.

A knowledgeable DIYer can perform some of the initial diagnostics, such as inspecting the communication cable and checking the connector at the X-14 position for visible damage or looseness. However, verifying the 5 VDC output from the microprocessor requires a DC voltage meter and comfort working around live control boards. If the microprocessor or inverter board needs to be replaced, most homeowners will want a qualified technician to handle that work.

Repair costs depend on which component has failed. If the issue is simply a loose or damaged cable, the cost may be limited to a service call fee, which typically ranges from $75 to $150. Replacing a microprocessor control board generally costs between $150 and $400 including parts and labor, while inverter board replacement can range from $200 to $500 or more depending on parts availability and labor rates in your area.
