Having a bit of a problem with a CELTIC FF combi boiler in trying to get the boiler to fire up:Turned switch on front to hot water and heating :pump runs.I then press the ignition button in for 15 seconds as instructed but pilot doesnt light once i release the ignition button the fan comes on but due to the pilot not being on the main burner doesnt fire up.

Checked 240v to boiler= ok
checked microswich from ignition to pc board = ok.
Checked both fuses on pc board= ok.

am i rigt in thinking the pcb is nacked or am i missing something. The boiler is 10 years old and had a new fan and expansion vessel fitted about 3 years ago if thats any help.
