Maytag Washer Error Code F6E2: Communication Error... | appliancefaults.com

Technical Background:

The F6E2 error code indicates a communication failure between the main control board (MCU) and the motor control board. The MCU sends signals to the motor control board to control the motor's speed and direction during different wash cycles. This communication usually occurs through a serial data line. If the MCU doesn't receive a response or receives a corrupted signal, it throws the F6E2 error. Voltage fluctuations or wiring issues interrupt the data transmission.

Symptoms:

Homeowner reports that the washer displays error code F6E2. The washer may not start, or it may start and then stop mid-cycle. The control panel may be unresponsive or display erratic behavior.

Possible Causes:

Loose wiring harness connection between the main control board and the motor control board.
Damaged wiring harness or individual wires between the boards.
Faulty main control board.
Defective motor control board.
Voltage supply problem to either the main control board or motor control board.
Software glitch within the main control board's firmware.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the main control board and the motor control board, typically behind the control panel and at the base of the washer, respectively.
3

Inspect the wiring harness and connectors between the boards for any signs of damage, corrosion, or loose connections. Disconnect and reconnect each connector to ensure a secure fit.
4

Using a multimeter, check the continuity of each wire in the harness between the boards. Repair or replace any wires with breaks or shorts.
5

Verify the voltage supply to both the main control board and the motor control board. The main control board typically requires 120V AC. The motor control board may need both 120V AC and a lower voltage DC supply (e.g., 12V DC), check wiring diagram. Use a multimeter to measure these voltages at the boards.
6

If the wiring and voltage are correct, the main control board or the motor control board may be faulty. Replacing the main control board is usually the next step. Record any model numbers on the board before purchasing a replacement.
7

After replacing the main control board, clear the error code by running the diagnostic cycle. Refer to the service manual for the specific procedure.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any troubleshooting or repairs. Capacitors in the control boards can store a high-voltage charge even after the power is disconnected. Use caution when working around electrical components. Always follow Lock Out/Tag Out (LOTO) procedures.

Prevention:

Regularly inspect the wiring harness for any signs of wear or damage. Ensure the washer is plugged into a dedicated outlet to prevent voltage fluctuations. Avoid overloading the washer, as this can strain the motor and control boards.

Expert Tip:

Sometimes, simply unplugging the washer for 15 minutes can reset the control board and clear the error code. Also, accessing the service mode (often a button combination like holding Start/Pause and another button while plugging the washer back in) can provide more detailed diagnostic information.

Frequently Asked Questions

•How do I access the diagnostic cycle on my specific Maytag washer model?

The diagnostic cycle access varies between models. Consult your user manual or search online using your model number and the term 'diagnostic cycle'. Often it involves a specific button combination or sequence.

•Where can I find a wiring diagram for my Maytag washer model?

Wiring diagrams are usually located inside the washer cabinet, often taped to the inside of the back panel or near the control board. You can also find them online by searching for your model number and 'wiring diagram'.

•How do I test the motor control board to see if it's faulty?

Testing the motor control board requires specialized knowledge and equipment. You'll need a multimeter and the wiring diagram. You can check for voltage at the board's input terminals. However, diagnosing internal board faults often requires replacing the board for testing purposes.
