    Default Blanco dwf6x6 circuit

    Belongs to a friend. Fills with water, does not wash, and pumps water out.
    Service guy tested the motor by bypassing the control board as cactus.
    $300.00 + Install.

    Any clues ?

    Looks like this model uses a simple induction motor for the wash pump.
    These little PSC motors need a start / run capacitor (item 4200 in exploded view) to operate and have very little starting torque.
    I would suggest checking the capacitor before condemning the motor. Also never rule out the impeller being physically stalled by debris like a chicken bone or other food scraps.
    The service tech would have just shorted the pump relay to stooge the motor into starting; this method doesn't check the capacitor or any physical blockage of the impeller.

    When the board was by passed, the motor ran fine and no blockages.

    Sorry I misunderstood, thought the motor was not spinning.
    Wouldn't rule out the relay on the PCB. Most of the European PCBs tend not to be potted, so component replacement is possible.

    Looking to get some sort of circuit before I see the unit.
    I can test the relay with external power supply easily enough.
