baxi 105e combi high co levels

[dean.]

i had to disconnect the above boiler tonight as the co was going of the scale on my anton. I had the flue striped apart and all the joints are fine. The air intake is normal with no poc. I was speaking to heat team but they had no answers.The burner pressures are set. Im going back tomorrow to spend more time on it, has anyone got anything i should be checking. cheers

sure its a e and not a HE?

 

[dean.]

Injectors and burner, give them a clean. I'd make sure the flue outlet seal is good if you haven't already.

 

[dean.]

yea i will do, i was planing on stripping the hole burner and fan tomorrow. ive checked the seals they all seem fine.

 

[lame plumber]

insulation panel cracked and fallen on burners can cause the issue!

 

[GrahamM]

Would say this is a full burner out strip clean job!

 

[R1CKY]

What state is the heat exchanger in? Fan running at correct speed?

 

[arran197]

What was the outcome of the strip out Dean?

 

[dean.]

it fixed the problem, striped out the fan , burner and injectors gave them a good clean, i didnt notice anything different but when they were reassembled it worked perfect.

Check the fan speed, seen it cause high co levels on glowworm microns a good few times
