I got AP4009231 as not all the lights were lighting on the control board when pressed. After installation of the new board different lights would light up, but still not all would light when pressed. The dw seems to cycle through the appropriate cycles, but I'm not sure. On either board do the normal heavy wash light come on when pressed, but the Dishes come out clean. Is it the "other circuit board" as listed as 12a or the touch panel, or is the circuit board defective? thanks.
ANSWER Hello William. If the buttons are not working properly, you will need to replace the control panel 6-919765 on the unit. Hope this helps.
