Also worth checkin the 4 connections at the rear of the drum.There are various connections here including temperature elements and earthing points. The vibration of the drum can often snap the wires here.
F-02, F-03, F-05 , F-07 ,F-11 These fualts can all be generated by a simple break in the wire or a poor connection here. There are many other ways to generate these faults but often it is something very simple and easily overlooked.
Failing this it is then worth checking that all the other visible connections are tight. A spray with WD-40 doesnt hurt. You can also try cleaning the contacts on the main circuit board with a hard clean rubber its amazing how dirty they can get.
