Myson Orion won't fire up - please help?

When I switch the heating on, the vent fan comes on and the pilot light ignites and stays on, however, the system continues to click constantly and the main burner does not ignite.
It was previously clicking constantly for a week or so but otherwise worked OK so I suppose the constant clicking was a warning that something was about to fail. Any suggestions to the possible fault would be appreciated.

When the the system fires up it will take 3 to 8 attemps to light.
Works perfect when it lit.

This is a list of things that have been changed

What else can I do? Please help?
Many thanks David

the circuit board is not detecting that the pilot is lit, thats why it keeps clicking. you need a new circuit board, or maybe an new electrode (probably circuit board).
