Fridgidaire Washer Error Code 43

Washer won’t spin in any cycle, but if I go into diagnostic mode, every function works perfectly, except it issues an error 43. The code description state "control board problem - replace control board", which I’ve done. Since it is a spin problem, I’ve replaced the motor control board as well, but the code resest if I clear it and it simply won’t spin if any regular cycle is selected.
