Potterton Promax 15HE Boiler -relay clicking problem

Potterton Promax 15HE on an unvented boiler installation has suddenly stopped heating both DHW & CH. Now when reset, fan starts up and runs while boiler does not fire up but has a relay on the ignition PCB clicking in & out for about half a dozen times and then locks system out. Seems gas valve operation is being inhibited by clicking relay action.
Would greatly appreciate advice on what may be wrong.
Thanks.:confused:
