Have a two year old Electrolux washer-dryer combo Model FFLG3911QW0. Motor quit running during a wash cycle - neither the agitator nor spin basket move. On board diagnostics give an Error 59
• Drum mechanical locked
• Motor
• Wiring or Motor Control Board

Agitator and spin basket can be moved by hand. Ordered new motor control board and installed but did not solve problem. Spin basket and agitator must be pulled to replace motor. Any suggestion or additional test to run to pin down source of problem.
