HW/CH 7 day programmer - steamed to death?

[PaulStat]

So I have a Drayton LP722, I was stripping wallpaper with my steamer last night, around the programmer.

This morning I got up and noticed there wasn't any hot water! Looks like I steamed the poor thing to death. Anyway just looking at the instruction manual (click link) and notice it mentions a 3A fuse. Is the fuse going to be in programmer itself or part of my main fuse box?

I can't check at the moment as I'm in work.

It was a simple job of unscrewing a single screw to remove the programmer from it's backplate.

Usually there should be a switch fused connection which has a 3amp fuse for the central heating boiler to isolate the supply, there is no fuse within the programmer.

Unlikely the fuse has blown though.

Yeah I know but I was only reading the manual on the way to work, so too late by then.

So more likely I'll have to replace the programmer then? From what I can see the programmer is wired into the junction box as well as the boiler/pumps/thermostat. As a result the boiler is off as well.
