I have no power to provide a display on the boiler so don't have a trouble shooting code at all.

Don't think it can be the fuse because the separate timer box still has power. When I switch off mains supply, where fuse is located, the timer box goes off too.

I had a new electric meter installed 24 hours ago and I wonder if the interruption in power supply has tripped a switch somewhere?

I initially thought the system had overheated, but can't reset because no display is available at all, even though it has had the chance to cool down now.

Any suggestions much appreciated
Thanks

Many thanks for responding so promptly - what's the PCB? and how much is it likely to cost to replace?

I can go to the plumbing/electrical supplier tomorrow and pick one up if it's not too pricey. Otherwise I don't get paid until next week and it will have to wait.

Regards
