If you do not centrifuge first, check the motor torque (this frees the gears, to perform the centrifuge), plastic support (if it has one), this must be well placed or makes the motor torque slip, and lever that releases the gears, then check the motor consists of three wires, blue (neutral) and Red and Yellow joined these last two to the capacitor. To test the motor, first connect the blue with the red to the electrical network, this will turn to the side, then connect the blue with the yellow, this will turn in the opposite direction. In both directions try to move the lever to release the gears would have to centrifuge, unless it has no force changes capacitor, Another thing you have to check is that the pump has no set and its hoses (the pump has to work during the centrifuge cycle). I hope I can help you with anything at your disposal. Best regards.
