EF9 is a board fault.
E57 is an inverter current issue.motor faulty,wiring issue, motor control board issue
do a continuity test on the loom from the motor to the control pcb.broken wiring will cause E57 issues.be careful if you go down the board route as any fault on the machine will blow the repaired board straight away.I have had this fault and it was a straight board issue but BE AWARE it might not be the only issue on yours!
