The lights on the keypad of my Fridgidaire dishwasher began to flash and there is no response from the diswasher when the buttons of the keypad are pressed. Currently, the "rinse hold" light is lit up and the dishwasher seems stuck in the rinse mode(when you close the door, the dishwasher attempts to run on its own and at random times)I would like to be sure that replacing the control panel/circuit board portion, will solve the problem before I order one?? Thanks
