    Last Friday while cleaning the water rollers a rag got sucked up between the rollers and jammed the water roller motor. We turned the press off as soon as possible, removed the rage, but the motor has not come on since. This morning (Monday) I removed the motor and plugged it into a different unit, and it ran, so that eliminates the motor itself as a problem.
    Any suggestions on where to look next would be appreciated.

    Do this:
    1) Take the control board of the motor that is NOT working
    2) Install in any other unit, that motor is working, if NOT work the board is fault
    3) If it work, test the Voltages feeding to the motor see the ID plate of motor if is AC or DC voltages, look for the Fuses if are Open with DMM, and replace if there are NOT fuses, see the C. breaker if are Tripped and reset.

    There is only one water control board, but I did try swapping the plugs from motor 2 and motor 3. The result was the same, motor 2 will not turn, the other will even with the plugs swapped. I have looked for fuses or circuit breakers for the water motor rollers, but so far can find none.
    Thanks for the input.

    Sir did you Test the Voltages as Indicated with The DMM?
    test the Voltages feeding to the motor see the ID plate of motor if is AC or DC voltages, look for the Fuses if are Open with DMM, and replace if there are NOT fuses, see the C. breaker if are Tripped and reset.?
    otherwise, the Motor is fault, the windings and the Recover is faulty.

    I checked the voltages at the small posts on the circuit board for each unit. They are within specs. I removed the motor and plugged it into the power supply of one of the other units and it turns. I swapped plugs on the circuit board and unit 3 motor turns when plugged into the unit two plug, but unit two does not turn when plugged into unit three terminal. I could not find any circuit breakers or fuses, so today I am going to trace the wiring from motor to board to see if I can find a burnt or broken connection. Thanks again for your input.

    Please do this:
    Perform a visual inspection : look for loose and broken wires, improperly seated connectors, loose or broken wires
    misset switch, missing jumpers. and so on.
    Chech for obviously damaged component(components burned or discolore due to overheating);
    Use the DMM(Digital multimeter) for to do: Continuity test for wires, etc.

    Someone else came and found circuit breaker that I had overlooked. A simple push of the button and it was fixed. At least now I know how some of the wires are routed, and will take care not to repeat the same mistake. Thanks again for your input.
