If you see the FE code on the display, your washer is getting too much water. This may be due to a faulty inlet valve. If that is the case, take steps to replace it. Bad inlet valves cannot be repaired.
Check the filters in the valves for clogs. To do so, unplug the machine, turn off the water supply tap and pull out the hoses. Check the water valves’ filters to ensure there are no debris. Check the hoses for clogs too. Use a good-sized tub or bucket. If necessary, clean the hoses until water runs freely through them. Reconnect the hoses, turn on the water supply tap, plug the machine back in and run a quick cycle to check if the error iss gone. Most likely, it will be ok.
