F3 is the OUTER door assy not closing properly. You may need a new outer door solenoid assy or at least have it checked by someone suitable.

hi
i think f3 means inner door switch not closing
close the inner door and release handle slowly listening for a click as the switch closes if not you will need a complete switch assembly
check on the display for fault info.
