That's good to know. Would at least have a clean slate that way - and possibly a manual to go with it too.

Hi, I've just moved into a new house with the above alarm fitted. The keypad is showing "Alert! Enter code" but neither I or the previous occupier know the code for it (they had a dog, but my cat is not nearly as effective as their German shepherd!) It was fitted by ADT and they want a kidney...

Fair enough guys... and understandable. I didn't actually realise you weren't allowed to say but it makes sense when you consider the potential for disaster. Like I said, with it being a spark problem, thought I'd try all the electrical side of things that I can get to first before calling the...

I use washing powder instead of swarfega... cheap and effective - didn't think of trying it with oil spots though, great idea!

Great response - many thanks

It's definitely not part of the sealed unit. Not unless massive gaps at the bottom and top count as sealed anyway.... No fear, staying well away from the combustion chamber!

This.... and a 17 year old 45 isn't worth much. Treat yourself to a new motor - you deserve it!

As long as it's the today grade for your motor and you don't stretch your service interval then it should be fine. If you have a high end turbo engine then maybe consider a premium brand just to be safe but if it's going in a 1.2 corsa it shouldn't make a difference. I tend to use cheaper stuff...

Petrol works well on block paving... not sure about tarmac though.

Plus gas and a breaker bar. Don't be shy with the hammer. Worth checking on a model specific car forum to see if it's a captive bolt too - or splined as mentioned earlier.

Think I'll go with your first response.... sure it's something simple but I'm not going to open it up. Last time I had a problem with this $hite thing it was just a dirty air switch but tried all the easy stuff now and no joy. Will have a ring round tomorrow and get someone out.

Sounds like you know but you're not telling..... ;) Fair enough if it's something internal, I can understand why you wouldn't want an amateur opening things up! Just wanted to try and eliminate any wiring / pcb issues first as they are easily accessible.

Badly worded.... The burner cover is on so it IS sealed (I'm not a complete moron) just removed the outer case so I could see if it was igniting - can't see the viewing window without doing that. It was only serviced in Feb so I wouldn't expect there to be any blockages. I checked the external...

Umm - was hoping to eliminate some of the obvious myself first. What voltage should the air switch be putting out if it's functioning correctly, are there other places I can can test to establish which section is at fault, etc

^^^ this. Copper is strong and pretty malleable, so shouldn't be an issue unless it's been dented with something sharp that may cause it to split (unlikely). If it isn't leaking now, chances are it won't.

Boiler isn't going into the ignition stage. Hot tap goes on, fans start, air switch clicks, but no spark. Tried the usual off/on/reset but no joy. The light doesn't show any error (which is strange) just the usual green flashes. It started playing up a couple of weeks ago but when I take the...

Just in case anyone does a search for this problem, like I did.... thought I'd post up the solution rather than leave it unanswered. Turned out just to be a bit of dirt in the pressure switch. Pulled the front off, unbolted the cover to the fan at the top right, then just cleaned out the...

Pulled the front off this afternoon and can see that the gas comes on for about five seconds before cutting out. Pressure gauge is now showing about 0.7 bar (it was 1.1 yesterday). Any suggestions or is it engineer time?

Thanks for the responses folks... The pressure gauge reads 1.1, so within normal range. LED does not go red at all... always flashing green - just faster when I turn something on. Is it still worth trying to increase the pressure slightly - if so, what up to as a maximum? About 1.5?

Hi, this is my first post so please go easy on me! I have checked the FAQs and already gone through the first ten pages of posts after searching what is in my thread title, but none of them had the same issue I am getting. My indicator light is flashing green every ten seconds, which means...
