Fuse repeatedly blowing on potterton Boiler Clock/Programmer

[jumblemo]

Hello All,

I'm a bit of a diy n00b, but I can at least change a fuse. So I felt bit foolish paying a central heating engineer £65 to get my heatin re-started when the problem turned out to by a dead 3amp fuse in th mains socket that the boiler programmer (Potterton EP2001) wa connected too.

However since he first visited in late December I have since woken u on three separate mornings to find the house cold, and fuse blow again.

Can anyone advise as to what is likely to be the cause of the fuse blowing?

You have an intermittent short circuit somewhere in your heating equipment or wiring. I would start by looking at the pump - 'cos that's where water and electrics come closest to each other.

An intermittent fault somewhere in the electrical system. How long does the fuse normally last after you replace it?

I would think that the fan and the heating pump are the only high load items. Mine just cost me for a fan although the fuse never blew. The unit just would not fire-up at all.

Well, it's unlikely to be the programmer

Possibly the pump, maybe the fan

Of course, if you'd mentioned the model of boiler, further advice might have been possible
