Same exact issue. MCU went bad, replaced with new, now just sticks in unbalanced mode. Never gets to high speed spin in Cycle mode. Passes all C00-C08 and gets high spin no problem. Pump is pumping water and clean, no clogs, no leaks, diaphragm in pressure switch is good. No errors in diagnostics mode, high spin, in any cycle just stays in unbalanced mode. Unplugging and letting it sit doesn't work. Need a button configuration for calibration I think but there is nothing on the Internet or in the manual about how to calibrate this model. Using clean washer mode works as normal, even high spin, but all cycles do not with or with out load. Doesn't make any sense. Also has new shock. It spins like new in diagnostics mode.
