My Worcester Greenstar 24Ri boiler was working yesterday morning, but did not come on yesterday evening.

It is like is has no power. I'm sure the boiler is getting power. The programmer is fed from the same power source and it is working.

I've taken the housing off and checked fuse F1. This had blown. I replaced it and it has blown again.

What is likely to be wrong?

Had a man come round and look at it. The transformer had gone.

Get someone competent to look at it.

It HAS got power. The problem is there is a fault that is causing the fuse to blow.

My guess would be the main PCB but you need someone competent to look at it.
