Paul,
I also have just got the F11 error code.
Having searched the web, it seems like the answer is the fuse is blown on the power board.
To access the board you need to SWITCH OFF & Remove the plug, then undo the fixing screws on the back plate, remove the backplate, the board is a bit of a mother to get to......so take it easy, and then remove and check the fuse, replace if required..........
Im told if replacing the fuse dont work...then u need to replace the whole board....hope this helps
