Push the start button, unit begins filling normally but then shuts right down. Ran a motor control control check. Motor runs. Repair manual and says thats the RD30 wire. Harness and wires though look ok, so do connections. Can it be the motor control board ? Do not see anything burned out. 10 amp fuse is also ok. Or is it the machine control board? Or do I just order a new wire harness ?
