I had the fault code F14.
I removed the top, rear and front cover (the front was trickier to remove). I found a puddle at the bottom inside the washing machine which I dried out thoroughly. The problem remained so I removed the wires from the switch above the white polystyrene float and the problem was cured. I reconnected the wires and I got the F14 message again. I then removed the switch completely and found it was wet! I placed it in the microwave for roughly 20 seconds to dry it out. I reconnected the wires to it and the F14 fault was still there. So I put the switch back in the microwave for a further 10 seconds and then reconnected the wires to it again. This time the fault was gone!
The cause of the puddle???
I checked all the pipes and found they were all ok. There were no tell tale signs of water running down any of the pipes or metalwork. The ONLY possible cause I can think of for this puddle is that when we removed a waterproof bedsheet from the washing machine, trapped water which couldn't escape in the spin cycle spilled out between the inner opening and the outer front cover of the washing machine. This water then splashed on the bottom tray soaking the switch causing it to short and produce a false F14 fault.
