Kenmore Washer Error Code F/11

F/11 indicates a serial communication error between the Central Control Unit (CCU) and the Motor Control Unit (MCU). These two boards exchange data continuously during operation, and F/11 is triggered when that communication cannot be sent correctly. The washer shuts down to prevent running the motor under unknown conditions. The issue can stem from wiring problems or a failure in either control board.

No. When F/11 is active, the washer has stopped operation because communication between its control boards has failed. Running the machine in this state is not recommended, as the motor could operate unpredictably or not at all. Unplug the washer until the issue is diagnosed and repaired.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose wire harness connector, there may be no parts cost at all. Replacing an MCU typically runs in the range of $150 to $300 for the part alone, while a CCU replacement can range from $100 to $250 or more. Adding professional labor can bring the total repair cost to $200 to $500 or higher depending on your location and the specific parts needed.

In many cases, yes. Start by unplugging the washer and inspecting all wire harness connections at the MCU, CCU, and drive motor. Reseat any loose connectors and look for damaged or corroded pins. If the wiring checks out, diagnosing a failed MCU or CCU typically requires a multimeter and some familiarity with control board testing, which may be better suited to a technician.

A reset by unplugging the washer for a few minutes may temporarily clear the code, but if the underlying cause is a loose connection, corroded wiring, or a failed control board, the error will return. A reset is a reasonable first step, but it should be followed by a thorough inspection of the wire harness and control board connections.
