Whirlpool duet front load washer displayed E1 F6 code

Model Number: WFW9151YW00
Brand: Whirlpool
Age: 1-5 years

Our Whirlpool duet front load washer displayed code E1F9 and would not drain. Went online and saw how to check drain pump filter and that was the problem. Was clogged with you so cleaned it. Ran a small load in rinse and spin cycle and it then displayed E1 F6 code and would not stop filling. Stopped washer and it drained out fine but tried again and it just keeps filling until stopped. It does not fill when off, just when on. Help!

Here is what the manufacture says about the F6 E1 error code.

F6 E1 - Serial Communication Error
The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Possible Causes/Procedure

- 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).
- Make sure that the two ground switches are pressed correctly by the toe and rear panels.
- Make sure that ground switches are installed correctly, are not broken, and that 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. See page 5.
- After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 seconds.
