F6 error

Help! I am receiving the F6 error code on this front loading duet washer. We were also receiving a slow drain code on machine. We removed drain pump cleaned it and reattached to receive the F6 error. My husband has checked all wiring and harnesses. We did find one disconnected wire on motor which we reattached and the machine ran a full load upon 2nd load it filled up and when it came time to drain it coded out with the F6 error again. We have replaced the Mcu board and triple checked everything. Motor apins and appears to be fine. Any other suggestions? This machine was a replacement from whirlpool after we had repairmen here numerous times. We have also replaced bearings recently. Any other ideas before I trash the machine?

It’s F6 E? something I think on these. What’s the E#?

It’s E1F6 sorry I thought I posted that
