Worcester Bosch Combi Boiler fault

Gasket

Hi, i have a Worc Bosch 28 Si II has been fitted about 4 years, i keep getting the flashing light indicating ignition lock out, this happened about a month ago but reseting the system cured the problem. This no longer works and i am currently without heating or water. When turning the system on the fan starts but the system does not ignite. I have taken the cover off to expose ht leads and cannot see a spark of any sort?

Is it likely to be the leads or another problem

had a quick look on the net and it looks like it could be the PCB at fault

I have a similar problem - did you manage to find the fault?

Could be any number of things including a.p.s. Fan, Blocked venturi.
These are gas safety devices and are not for a diy person to be checking.
My advice is get a heating engineer out to look at it.
