F1 is flood error - water on the bottom tray. Turn power off at wall and remove bottom drawer. Completely dry bottom tray with cloth and a hairdryer to finish it off. Put drawer back & run only one drawer for a couple of days. If all ok, then just use the other drawer for a day or 2. If the water comes back & F1 returns it will at least give you some idea which drawer is leaking.
