F7 indicates flow meter has failed. This is the on the left side behind the panel, its the large plastic panel which lets water into the tub. There is a 2 wire connection at the bottom of the panel which connects to a water meter, check to see whether the impeller is turning when water enters the machine. If it is check you have good flow, as the machine relies on the machine filling within a certain time. The unit is easy to replace.
