Still learning this site. We ran full service diagnostics and every component from lid lock all the way down the tech manual list was doing its job. Control panel appears to be fully functional. We now suspect ACU control board, but ran out of time to perform any additional tests. Would appreciate any suggestions before we go up to tackle it again in the near future.
Oh, and prior to learning how to even run full service diagnostics, we physically inspected rotor and stator, clutch, and shifter/actuator and all of these components looked like new. I’ve been messing with this washer occasionally for well over a week now. Would appreciate any and all suggestions. Thank you!

All I have to go on is the error code you provided. If everything works in diagnostic mode, either the coil is good and not getting voltage from the board, or the coil is bad and is not able to respond. Sometimes the logic in diagnostics will not respond the same in actual operation. Testing a coil is hard due to temperature affecting the ohms reading. I would rather test it for voltage. Test 3A in your service manual shows how to check the shifter.
“All I have to go on is the error code you provided.”
Yes, I understand that. You’re trying to help from a distance and I’m a do-it-yourselfer trying to keep my nose above water!
Test 3a says to perform the spin and agitate tests in the Service Test Mode, which we did do. We could clearly hear the machine agitator working fine as well as the machine powering up through three spin cycles. These tests were all performed successfully, so even though the error codes suggest otherwise, the machine performed these tests successfully in the Service Test Mode. This leads me to believe that the ACU isn’t sending the appropriate signal and may, therefore, be faulty. Test 3a in “Functional Check” states: "Check the shifter and electrical connections by performing both the Spin and Agitate tests under Service Test Mode on Page 4 (machine successfully passed both tests). The following steps assume that this step was unsuccessful. IOW, you would test further ONLY if the machine failed the agitate and spin tests. Since the machine passed both tests, we stopped there.
That’s what I’m thinking, but there is a test for the ACU also, which we haven’t done because we ran out of time. If we do finally get this machine running, is there any reason to remove the old error codes? Will leaving error codes in the machine’s memory affect performance?
