Boiler cutting out/tripping

[nick1972]

Hi all, first time on here and I need some advice please.

My boiler keeps tripping. After the original boiler installers came to fix it and declared the problem was due to faulty electrics, I had it rewired onto its own RCD circuit, and it was fine for a while, but has now tripped every day for the last week.
I need to prove that it is the boiler which is at fault but need to check first that the electrics cannot be called into question.
The boiler is on its own circuit so am I right in thinking that there's nothing else electrically that could be interfering?
Also the consumer unit and boiler are both in the garage. It has been damp the last few days and although there's no water leaking in or anything, the fuse spur is on a single skin exterior brick wall. Could this be causing any issues?
The main problem is that it is intermittent. The boiler seems to trip around an hour after coming on in the morning (when its cold and damp), but within another hour or two, it works again. If someone came to look at it while it was working, would they be able to even begin to locate a potential issue with the electrics?
Thanks for reading & helping. This whole situation is very stressful and the boiler installers (A Shade Greener) are being very difficult / unhelpful.

Waterproof spurs are available for the spur. There is so many things it could be. I would echo @Murdoch if it is the circuit your electrician installed he can verify or disprove it and talk to the lovely boiler installers more convincingly than you no doubt. Or get another electrician in. In any event you have no choice but to seek independent witness regard the circuit or be doomed to go around in circles forever with your installers.

i can reach bury in 40 minutes (traffic permitting) , test that circuit and test the boiler all for the meagre charge of £75.

Could be a build up of condensation in the flue which after a period of time drips onto the flue stat. I very much doubt this is to do with the supply.

considering that the fault occurs when the boiler is operating I would say the fault is in the boiler or the control wiring, not an unusual build up of condensation behind a switchfuse.

What make and model of boiler is this?

If i may put the brakes on...what exactly,is tripping?

The OP has not told us what requires resetting,after this "trip".

Is it the RCD,the MCB,or the boiler itself,locking-out?

Thanks. I really appreciate that but I've called someone and they're coming today.

Its a Weissmann combi boiler.

Forgive the lack of technical jargon used here, but the boiler is on its own switch in the consumer unit. When the boiler trips, the whole house electrics go off. I pop into the garage, switch OFF the switch for the boiler and switch ON the main switch meaning that the house has lighting, plus etc.
Then I switch the boiler back on, and within anything from no time at all, up to three or four minutes, the whole thing trips off again. After maybe an hour, I can switch the boiler on without everything else going off.


Thanks everyone for your input today. It has taken a weight off knowing that I have you on my side. Cheers!

If the whole house is fed from one RCD, then the cummulative leakage may be close to the RCDs trip level. The boiler may just push it over the edge.

You'll have to pay an additional £75 to get rid of Tel though........... ;o)))))

Right, instead of faffing around like the old cronies on here, what make and model of boiler is it any photos of install and any issues with frost lately?

what's it matter. with any boiler if it can't be fixed with a hammer or duct tape, it's an electrical problem.

There are two RCDs on the consumer unit, so when I said earlier that the whole house electrics went out, that's not strictly true. However if the boiler was pushing it over the edge of what it could handle, then that's the fault of the installers to not have taken it into account when fitting it surely.

Box of matches as how do you ignite the gas........

AKA the bang test.

Hope the spark you have called has an earth leakage clamp meter!

Well it wasn't me, 'cos a week on I'm still waiting for my Megger one to turn up!
