Less than 2 yrs. Used less than 100 times. All parts look in good condition. Suddenly stopped running. no agitation, no spin, but water pmup works fine. lid switch works fine. timer's motor works fine. belt is in good condition. Before reset it, the light on motor flashed 6 times continuously and the error code says 'locked rotor'. After reset motor, the light flashes in 'normal standby' only. Question: what possible problem could be ?
