Yay! Hopefully it should be easily done then :D

 

If there is no fault code showing then it may be that there is no demand returning to boiler from external control/timer....easily checked by linking terminals 3&4 inside the boiler

Hi, i am just needing some advice, i have got an airlock in radiators and the boiler wont fire up, i have tried bleeding the radiator but no air is coming out or in one radiator there is no water coming out either, i have a condensor boiler. I would be grateful for any advice. thanks

Check the pressure on the boiler, there should be a small clock it should be above 1.5. if it is below this then there should be an outlet valve which you turn this lets the pressure go back up when it reaches around 1.5 turn it back to original position. Not sure if it is the same on the boiler you have but you can try. Good luck

is it a combi boiler?

if it is the pressure gauge should be 1bar when cold ie heating not on.

How do you no there is an airlock?

the pump could be jammed or the the auto airvent above the pump gathering air (inside the boiler casing).

Happy to help

Adam

sorry misread your post

check the valves are open under the boiler and the pressure is is registering if its a combi.

if you have tanks, check it has water in it.

also, the boiler does initially fire up for about 30 secs or so like its going to come on but then closes down again, it is a condensor boiler.

ok

is the heating pressurised though? or tank fed?

check pressure or that there is water in tank if its gravity fed.

as there is either a blockage or no water to upstairs radiator.

Sounds like faulty or stuck ball valve in central heating header tank or blocked cold feed.
