Afternoon all
Got a customer with one of these that is not working. To be honest got me stumped a bit.
Demand for heat, fan runs but doesnt get to the sparking stage.Following potterton fault finding guide, points to the aps and associated tubes etc.
Inner flue all ok and not blocked etc.
Case seal OK.
Changed aps, blew through hoses to check for splits, brass restrictor is clear.
Still not getting to the sparking stage.
Thinking it is the PCB that is goosed.

Any suggestions welcome.

Sounds like a dry joint on the pcb. Take it out and have a look where the multi wired plug fits to the board. They are notorious for getting dry joints on the end two pins.
