Turn the shaft sticking out of the potentiometer slowly until you get a reading of 19 on the potentiometer level on the display. The machine will also start beep continuously when the number 19 is displayed. Insert the new potentiometer into the knob or gear of the color change assembly being careful not to turn the shaft while doing it.
