F1 means that water has leaked in to the base tray and operated the flood switch. Until it is dried out it will not do anything except run the drain pump. Turn off the power & unplug from the wall socket. Remove the lower panel beneath the door. Inside you will see the polystyrene float and the float switch. You need to dry that area as much as possible. Use a sponge to soak it up. Once dry, put panel back on & restore power. Do not do this while dishwasher is still plugged in to the power socket because some of those wires are live all the time.
