My Baxi 105e combi is not working and all that is showing is the mains power on light. I'm guessing that the PCB must be faulty - no LED fault lights are showing - nothing apart from the mains power.
Just wanted to check if there's anything else that might cause this condition before shelling out for a new PCB.
It was just a thought,its always worth checking before spending serious money on a pcb.there are plenty on ebay just make sure the dip switches correspond to the old board

If it was the fuse surely the mains power indicator light wouldn't come on?

there could be a fuse on the board,if it is black inside the glass of the fuse it usually indicates a short circuit and 9 times out of 10 it's the pump
