You can ohm out the motor and sensor from pcb, since parts were replaced they are probably good but it doesn't hurt to make sure. Motor is rd, bu and yl and you should get about 10 ohms across all 3. Hall sensor is bu, rd, gy and wh. On the sensor connector you want to check bu and rd to wh, you should get a reading around 10k ohms on each. With unit powered on check wh to gy for dcv and you should get about 5 vdc. You can check gy to rd and bu and get about 2.5 vdc that will pulse back and forth as you turn the basket by hand. If you find all these readings correct then I would replace the main pcb.
