Before I can assist you further I will need to know the model # to begin with

The model number is WDF331PAMS0

We did a lot of research on this one after you called in earlier and according to the Manufacturers own listing information the control board you need is (Whirlpool W11613566 Dishwasher Electronic Control Board (Main Control) | Genuine OEM Part)
if the button is physically broken then the part # you need is (Whirlpool W11647416 Dishwasher Light Pipe With Button Tree Assembly | Genuine OEM Part)

I originally purchased part W11170174. When the part came in, there are no buttons that came with it so I see it is not the correct part. I need to know the correct part so I know what the exchange part is.
