potterton prima f80wall mount just stopped igniting?

I have downloaded a fault finding chart from Potterton web site under installation instructions, the fault could be resolved by changing the igniter and the cable to the control box and replacing the control box complete, the new control box fits in the other ones place nicely, a competant electrician can do the job power to the boiler should be off until the job is finished, total cost £210-00 inc VAT, we are warm now.
