whirlpool quiet mode 111 and it doesn't light up or start

Kristy Thompson, Make sure it has power. Reset the circuit breaker, simply turn it off for a minute then back on. If it still does nothing then you need to check the voltage at the junction box under the dishwasher. Remove the panel on the bottom front. Turn the breaker OFF. The junction is usually on the right side. One screw holds in the cover. With cover off you should see the wire connectors. If they are melted or dry and brittle it needs to be repaired. With a multimeter set for AC voltage loosen the wire but enough to get a meter lead inside each connector so it’s touching the exposed wire and nothing else is touching Turn breaker on and see what your voltage. If it’s less than 110v you can test the door switch then the control board.
