Hi all my Halstead finest platinum combi boiler will not fire up. Initially it was thought to be down to a pressure problem as the read out stated 0 bar however I have now resolved that by recompressing to 1.5 bar through the fill loop. However it still won't fire up i've switched it off and left it off for an hour but still no joy, just comes up with the red light with the CH lights flashing yellow, the in built fault display states that it is a pressure issue, really can't afford to get anyone out to look at it someone please help if you can!!! :scratch:

Cheers.

think you'll need someone out, it may be the pressure sensor wont read the pressure, after you've re-pressurised the system.

yes, the boiler will attempt to fire up a couple of times the blue light will come on for about 3 seconds then the light goes off completely and a couple of seconds later a solid red light comes on.

I had something similar to this on a Worcester Bosch CDi Combi - re-filled system after a draindown and it wouldn't kick in at all.

Turned out just to need an vent release on the boiler itself (about 8 years ago this, so memory bit vague). 5 second fix by someone who knew what to do :oops:

maybe you've turned off the gas in your turning off valves.

under the boiler make sure all the taps/screwdriver slots are in line with the pipes.

hopefully this might help

also ensure all the water taps are also in line with the pipes (open)

except of course the fill loop!

Thanks for your help guys, unfortunately the boiler seems to have taken a turn for the worse pile of sh**. Its now leaking water from the back of the pressure switch so i've turned off the water supply to it and hope it drains itself. Could it have been a pressure problem or a presure switch or reading problem as to why it wasn't firing up??? Anything I can do o do I need to call in the help!?!

Hi jonathan,
Try and get a no call out charge local engineer to call out and ask him to diagnose, you may be surprised.

Nothing ventured nothing gained.

no call out fee... means no charge to get to your door, once they cross the threshold, the clock starts, and so does the charges!

It may well be a problem with the pressure switch... really you need someone to dianogse the problem.

I've just finished refilling the CH system after doing quite a bit of work. At first the boiler (Keston Celsius) locked out and refused to start - even although the pressure gauge showed a reasonable pressure. I tried venting it with the manual vent in the boiler - no joy. Eventually I opened the drain cock underneath and bled off some air at that point and everything kicked into life.

Could well be as simple as a trapped pocket of air in your boiler.
