Can anybody help? i have a valiant combi boiler. i've got a pilot light on in the display window, but when i put the radiators r hot water tap on, it does not kick in? pressure needle was slightly down under the 1 marker? but nothing really bad, well i don't think it is bad ? could it be something
2 do with the pressure vessel....
have u topped the pressure up above 1 bar? may have a low pressure cut out switch in the boiler.

just to clarify: is your heating working but your hot water not?
Both water and radiators are not coming on?
and have turned pressure up 2 ust over the 1 marker, and sill no joy... it has run under the number 1 b 4 and not done this. i've got a guy coming out
2 look at it now 2morrow. he deals with valiant boilers only? so with a bit of lady luck, he might have the pat on his van and not change me the dinner trip er sorry.... journey for the parts i need... :-) hope its not a new boiler... don't know how much? but would not like 2 buy a new 1....i don't think it is about the pressure. My combi works fine at around that. It is valiiant also. Probably need to swop out the parts.
No.
Model would be helpful. Probably a VCW or a Sine...
Since it fails for both heating and HW it could be something common to both which really leaves most of the parts of the boiler... It could even be a failure of the electrical supply.
