Hi' all new member. Went to a glowworm space saver kfb 70 which won't fire' forth led light won't come on. Home owner had a engineer out who replaced the PCB, GAS VALVE AND ELECTRODE +LEAD+ NEW APS , but still didn't fire up. When top. Front cover is removed it. Will fire up, run and when demand met " same issue just sparks .

I have checked cleaned up the flue. And heat exchanger and fan. Cleaned the injector.
Fan dose run but could it be failing to that extent .
Any help. Would be much appreciated.
