Worcestershire Bosch Boiler

[Ric.ror]

I'm freezing - the boiler keeps firing up for a couple of seconds then off again!
Then back on then off again etc
The pressure is at zero but if it was that surely it wouldn't fire up at all
Or would it?

[emeritus]

Can you not repressurise it ?

[Ric.ror]

OH no I can't do anything like that
I might let eldest son and heir to my vast fortune have a look later but I just thought of it was firing up it would not be the pressure

[alavahalf]

It is the lack of pressure that is stopping it from running ..

[emeritus]

Some will some wont I believe. More to the point you need to find out how it has lost its pressure . eg. Water Leak on the system or the pressure relief valve has blown ??

[donny48]

Most boilers will need about 1 bar. I have known them to work as you quoted , your first move must be to re-pressurise the system.

[donny48]

Without anything dramatic such as a leak a system can lose pressure slowly and need a top up, if yours is a sudden drop then other things need looking into.

[donny48]

What model is your boiler ?

[Dodger666]

Has anyone been venting radiators without topping up the water pressure afterwards?

Does your boiler have a key like this, Rc.ror?

Err or you gas or oil. When mine fired for seconds - I had "run out" of oil.

I have had this and what a fiasco. My burner 2 years old on Sunday (the date is marked on it) - turns out (i) the photocell was kaput.....could be your problem if oil - my burner igniting but not continuing, the button going back to reset after a couple of minutes.

the second problem turned out to be the ignition assembly - but then the CO reading was 4000ppm.....somewhat high. This afternoon, they replaced it (£78 for the part) and it could all have been redundant as the guy who did it said we had a CO problem, the same reading, and no idea that this was identified on Monday...... A phone in, 'we can't send a senior engineer out to Tuesday' - a rant about Saturday and o-time and she comes back that they'll send someone out this afternoon....took him 30 seconds, he removes the eye tube that ups the air in and oomph up she goes and the CO level comes down to 21ppm.

The boiler is ancient - he takes the measurement of the top plate and they'll make a new one and then come and drill the rusted bolts out and clean the carbon out of the boiler...... The heat is now coming in - just as things are supposed to warm up this w/end.

Ok I'm not there at the moment
The thing is no one has been living in the flat for about a year - I have been weekly to water the plants but want to move in before winter really starts

[Ric.ror]

DCT - it's gas not oil

[DTCwordfan]

good luck with bringing up the pressure - it's pretty easy, ric.ror (as per Talb's video).
