Hi All
Firstly, a bit of history.
1) Boiler was brand new in a new build in july 2004.
2) PCB had lockout problems in november/december 2009 and i fitted a recon with higher grade components in december 2009 and have had just a handful of lockouts since.
3) On 04/12/14 i purchased another pcb and it hasnt fixed this problem.
4) Testing a brand new air pressure switch hasn't fixed the problem.
My boiler is not firing at all and is not even sparking or attempting to fire up.
When the boiler is called for heat, the fan comes on, i can hear a click from the microswitch opening (or closing) on the air pressure switch but no attempt at firing is made and after 60 seconds i get a lockout. It started with the extremely common lockout problems 2 weeks ago. Id come home from work, the fan would be running and the boiler wouldnt be lit. Id reset the boiler and it would then start up ok. This got worse and worse and since last sunday the boiler hasnt lit once. ive also noticed i used to be able to hear water flowing through the pipes of the boiler but now i cant hear anything but the fan running and the microswitch clicking.
i've had a plumber out who didn't know what the problem was and thought it maybe the actuator upstairs by the water tank as the lever on it seemed stuck but i've taken this off the valve it was on and am now manually adjusting the valve so water is flowing round.
As i cant hear water running through the boiler, i found a thread suggesting that there could be an air lock or a blockage and to take out the water pump and turn it around to reverse the flow then once it ran for a bit put it back to normal. When i did this, i could hear water happily flowing through the boiler but now i've put it back to normal i cant hear anything again.
When the boiler is called, and the fan starts, it is again intermittent that the pump starts running, i seem to have to take the power from the pump and put it back on at an angle to get the pump going but then it seems to be fine until i reset the boiler and the pump goes off again.
The boiler has a water flow switch fitted so i assume because i cant hear water flowing this may not be helping but even when i did hear water flowing before, it was still intermittent and would get the lock out problem.
About 1.1/2 weeks ago when it was intermittently working, i decided to tackle the problem of the largest radiator not getting very warm by locking down all the other radiators so the only place the water could flow was round the system and through that 1 radiator. This radiator then got hot (previously it had a domed cold patch from the bottom middle and only luke warm around that. I then adusted all the other rads so less flowed through them and more flowed through this one rad.
So far ive spent a long timing discussing this with one plumber and as mentioned above had another one come in to look and im getting no where.
And to top it its getting colder at the moment...
Desperate now and any help or questions for more info would be very appreciated.
