glowworm ultimate 40 ff wont ignite

[andy jolly]

can anyone tell me why my boiler will not ignite you can just here the fan runing and all fuses are ok

 

[gas4you]

APS switch knackered, dirt in the venturis, pipes come off that connect fan to APS, all RGI territory though.

 

[corgiman]

is it on a sealed system?

 

[andy jolly]

the boiler is about 2 yrs old and is a glowworm ultimate 40 ff if that helps

 

[andy jolly]

al pipes are conected and hooverd the boiler and fuses are ok

 

[corgiman]

do you have a filling loop or a gauge telling the pressure of the system?

 

[andy jolly]

its not a combi no loop for filling up .i have replaced the spark electrode still nothing happened .i left it for a few hours and then tried it again and it firerd up then i switched of and then it would not fire up again

 

[alan m 1974]

is it sparking at pilot or not,if not it seemss to be aps fault blow dowwn tube and see blow very lightly

 

[andy jolly]

no its not got the loop for filling and its not a combi .i have replaced the spark electrode.and it did not work so i left it for a few hours then i tried it again and it firered up .left it to run for a hour and then turned it of and tried to start it agai and it wont fire up again .do you think its the solinode

 

[andy jolly]

hi alan there is no spark just fan running and we have cleaned the pilot jet and fitted new electrode

 

[corgiman]

I know an ultimate isnt a combi thats not what i was getting at, I was trying to ascertain if the boiler was on a sealed system and you may have had a blocked low presssure switch.

But you have nt

blocked pilot light I would say

 

[andy jolly]

pilot has been cleaned out

 

[corgiman]

whats the resistance of the solenoid?

 

[alan m 1974]

I WOuld be looking no further than either a blockage in the tubes,faulty aps or fan not fast enough to open aps.I would check the tubes and aps first as it needs that to open to allow ignition sequence to begin

andy, on them the aps is on the side of the control box when you take the bottom drawer off just try removing a tube and blowing down the aps
