the up/down arrows on my ge pdw 9900 series dishwasher stick and will not allow me to select different wash cycles. the arrows are on the electronic module along withfive other enhancement selections. i can select the enhancements just fine. it is the wash cycle selection up/down arrow pads that will not work. the pads are the same for the enhancement features. its the type of pad you push to select the item. has anyone run into similar problem
