Trying to figure out what error I'm getting with this washer and Google has failed me so far.

I'm getting 3 beeps, "wash" light flashing, and "door lock" light is red. There is no display on this washer that flashes an error code (even though the manual for it says to look at the display).

I have power cycled it multiple times. Eventually it will stop beeping, let the door open, but if you try to close it and start a cycle it goes back to this.

Whirlpool told me there is no error code associated with the beeps/lights. This seems bizarre to me. Maybe that's the case. If so, where should I begin for troubleshooting?

I'm attaching your tech data sheet below.

Page 5--->On models without a display, the WASH LED will flash to indicate the error code. If there are no error codes stored, the WASH LED remains on.
NOTE: This program recalls the most recent error code first.

Page 10--->For non display models, the WASH LED will flash and the error code number is represented by the number of times the LED flashes. The first set of flashes represents the “F” and the second set of flashes represents the “E”. There is a pause of 2 seconds between the flashes for “F” and “E”. The error code sequence will repeat after a pause of 5 seconds.

How many times is the WASH LED flashing for the FIRST SET of Flashes? Then for the SECOND SET of Flashes?

I should have updated the thread when I figured it out but it seems like I have F6E1 error.

Ok F6E1--->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).
- 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. See page 5.
- After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 seconds.

You may want to UNPLUG THE MACHINE FIRST, then remove the MCU(Motor Control Unit) and look at the circuit board closely and see if you notice any burnt spots on it, than order the new MCU below and that fill fix it.

Here's the MCU for this model:
Main Control Board WPW10384843
