Hi, I have a Worcester Bosch 240 BF Combi Boiler. I tried to turn the central heating on but the boiler didn't fire up. However it does when I turn the hot tap on. There is no external room thermostat connected and I've changed all the fuses in the boiler to be on the safe side, but still no luck? The water pressure is fine also. Any ideas what could be wrong? Thanks.

You need to check there's a demand into the PCB. Are you ok to do a few wiring checks with a multimeter? There's a wiring diagram on the back of the white case that you lift off...

Hi sorry for the late reply, i've been on holiday!
You need to check for 240Vac into the main PCB from the controls. There's a wiring diagram on the back of the front pannel but if you're unsure of how to do this, you'll probably be better off getting someone in for safety reasons.
