Trying to change the heating element in my Bosche cooker.
Taken the cover board off and one of the screws holding the element was behind fan. Have taken bolt holding fan on by turning clockwise but now fan won't come away. What do I need to do next? I have pictures if this would help to answer? Thanks.

Remove the locking washer between the nut and the fan blade,hold the shaft with a pair of pipe grips on the flat section so it cannot slip, turn the fan blade left and right repeatedly and it should gradually free up till it can spin freely on the shaft, then pull it off. If it does not free up use some WD40 but this will make it smell when you first heat it up
