When cycle is selected and unit turned on door locks then nothing happens, after a while code F6E1 comes up. Unit will not power down until plug is pulled and door will not unkock by itself. This code seems to be common with this style washer. What is the most common repair?
Answer Hello John,
The tech sheet on the unit says this about the fault code:
F6E1 FAULT CODE: SERIAL COMMUNICATION ERROR
The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.
- Unplug washer or disconnect power.
- Check that the power cord terminals are connected at the right position to the RFI filter (white-Neutral/ black-Line).
- Check that the two ground switches are pressed correctly by the toe and rear panels.
- Check that ground switches are fitted correctly, and are not broken and the green ground wires are connected correctly.
- Make sure that both ground switches are not broken or scratched.
- Make sure that all the ground harnesses (green wires) are connected correctly, and are not broken or with wires detached.
- Make sure that all wire harness connections from the CCU (MI3 cavity), main Motor, and MCU are not broken or with wires detached, and that connector internal pins are visible.
- Check for continuity from the MCU connector wires to CCU (MI3 cavity) connector.
- If the continuity diagnosis failed, the Main Harness must be replaced.
- Make sure that all the connectors are fully seated.
- Check the drive system for any worn or failed components.
- Plug in washer or reconnect power.
- Verify the washer operation by running the Diagnostic Test cycle.
- After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 seconds.
