F6E1 is an error code, which signals a communication problem between the CCU (Central Control Unit) and the MCU (Motor Control Unit).
Why it happens and how to fix it.
- Disconnect power or switch off your washer.
- Make sure that the power code terminals’ connections on the RFI filter are not reversed or confused (white-Neutral/ black-Line).
- There are two ground switches pressed by the rear and toe panels. Make sure they are pressed properly, not damaged, and the ground wires (green) are not loose and connected properly
- Check the ground harnesses (the green wires) and make sure they are not loose or disconnected.
- Check the CCU connections (M13 cavity), MCU and main Motor are intact, not loose or damaged, and connector internal pins are ok.
- Check the wiring between the MCU to the CCU connector (M13 cavity) for continuity.
- If the continuity is bad, replace the main harness.
- Be sure that there are no loose connections.
- Make sure that there are no faulty or worn components in the drive system.
- Plug the washer back in/reconnect it to the mains.
- Run the Diagnostic Test cycle to ensure that the washer is working well.
- After the diagnostic, disconnect/switch off the washer and wait for about 15 seconds.
